The gas heater does not ignite, goes out or clicks

Clap when turned on

If, when you turn on the column, you hear a pop, this is a sign of problems with the gas supply. Each device has a working area in which gas accumulates when the equipment is turned on, as well as its gradual connection with air. If the volume of accumulated gas and air corresponds to the manufacturer’s calculations, there will be no pops. If gas and air accumulate in excess, it causes a small volumetric explosion.

It not only causes a loud popping sound, but can also damage the chimney, so this situation should be corrected immediately.

The author of the following video offers his solution to this problem. After watching his video, you can independently get rid of the cotton when you turn on the gas water heater.

The speaker hums and makes noise during operation

The cause of noise when heating water is insufficient draft. Therefore, in noisy equipment, it is the first thing to check. A lit match or lighter is brought to the control holes or a special hatch in the upper part of the column. If the flame deviates towards the device, the draft is sufficient. Otherwise, care should be taken to clean the chimney duct.

Also, noise can be caused by insufficient air flow into the room, for example, if plastic windows are installed in the kitchen. The seals in such windows interfere with the natural ventilation of the room. In this case, to eliminate noise, you should simply control the air flow.

Another reason the column is too noisy is that the pilot burner wick is dirty. And then to eliminate the noise, it is enough to clean the jets. A similar situation is possible if the jets in the main burner are clogged, then after cleaning it, the hum during operation of the column disappears.

In modern speakers that are turned on using electric ignition, the cause of noise during operation may be as follows:

Discharged batteries. As a result, the gas-air mixture is difficult to ignite. In such a situation, the batteries need to be replaced.
Damage to the sensor that controls the water supply. Often its malfunction is caused by oxidation of the contact group. Usually this sensor is not removable, so it is replaced.
A spark plug malfunction prevents an electric spark from being produced. Most often, it shifts after many heating-cooling cycles. By returning the spark plug to its nominal position, you will restore the possibility of spark formation and eliminate extraneous noise.
Problem with mechanical ignition retarder. Its presence can be determined after dismantling the assembly and shaking it - normally you should hear the noise of the ball moving inside the moderator. If there is no sound, this indicates that the ball is moving. You can return it to its place using a soft wire.

The speaker whistles

If a monotonous loud whistle is coming from your equipment, you should first determine where it is coming from. To do this, turn off the gas tap, and then open the hot water tap. Further actions depend on the resumption or absence of “trills”:

If a whistle appears, its occurrence is associated with the water path. The most common reason for this sound is scale deposits in the heat exchanger or a foreign object getting inside the pipe. At the same time, the performance of the column decreases. In this case, to get rid of the whistling, you need to clean the heat exchanger from scale, and the reverse flow will help wash out the foreign object from the column.
If there is no whistling sound, the cause of its occurrence was problems in the gas path. Most often they are associated with a defect in the valve that modulates the flame power. Then the whistle appears only at a certain power, and to eliminate it, you need to adjust the power in any direction. Another common cause is a clogged tract. Whistling sounds appear at any power. To identify the location of contamination, you will have to carry out extraordinary cleaning, which is best entrusted to a specialist who works with gas equipment.

The gas water heater is noisy, whistling, humming: what to do

Is the gas water heater noisy? It is necessary to find out the reasons: they depend on whether the equipment is new or has been in operation for several years. To find out why the speaker hums, hisses or buzzes, let’s look at its structure and operating features.

The principle of operation of the gas water heater

The column or flow heater, as it is called, is a metal box (casing). Two pipes are connected to it for supplying water and gas. The main design elements are:

Radiator (water flows through it).
Main and pilot burners (serve to heat the liquid in the radiator).

When the user opens the faucet, the valve opens and allows gas to flow into the burner. It lights up and the gas heats the heat exchanger. Combustion products are removed through the chimney and ventilation.

Causes of noise

Due to the very principle of operation of the equipment, you can hear a slight noise, it crackles. Sounds may be amplified if the room is not well ventilated. There's nothing wrong with that.

Does the appliance make sounds when turning on hot water or heating? When drawing water, you may feel vibration because the flow passes through the pipes, turns, and passes through obstacles. To reduce the noise level, you can adjust the water handle. While scrolling it, listen: as soon as the sound vibrations decrease, leave it in this position.

There is a popping sound when starting up

Do you start the equipment and hear a pop? Does the device jerk and vibrate? This means there are problems with the gas supply. When starting, fuel accumulates in the working part: when the amount of air or gas corresponds to the norm, no popping noises should be heard.

Excessive gas results in a volumetric explosion when the fuel hits the wall at the bend. This can happen if there is excess pressure in the system.

Such problems can even lead to the failure of the chimney. Therefore, contact a service center or try to fix them yourself.

Turn off the gas and water supplies.
Remove the equipment casing: pull the handle towards you, unscrew the two screws.
Inspect the fuel supply system and burner. Clean the parts from dirt. How to clean a gas water heater, read the previous article.
Unscrew the two burner tongue screws.
Inspect the condition of the nozzle. If it is clogged, clean it.

The speaker hummed and made noise

The main reason is poor traction . To test it, light a match and hold it near the hole. If the flame deviates to the side, as if from an air flow, the draft is fine. If not, the chimney channel is clogged with soot and carbon deposits, which are produced during the combustion process. Need to clean it up.

Poor ventilation also contributes to increased noise. This often happens after installing plastic windows. The bags are so sealed that natural ventilation becomes impossible.

What to do if the device cracks? This is possible when the burner nozzle (nozzle) is clogged . You need to disassemble them as described above and clean them.

If your column is turned on by electric ignition, the reasons may be:

Such devices operate on batteries. When they are discharged, the fuel ignites poorly or does not ignite at all. Clicking sounds may be heard. In this case, replace the batteries.
The flow control sensor is faulty. Most often, its contacts oxidize under the influence of moisture. You can try to clean the contacts, but it is better to replace the sensor.
The spark does not ignite. The candle that is responsible for the fire has moved, so the process does not complete. Reinstall the spark plug and resume the process.
The ignition retarder does not work. Remove the part and shake. In this case, you should hear the noise of the ball rolling in the housing. If you don't hear anything, the ball is stuck or dislodged. Put it back in place with wire.

Is the new equipment rattling? Perhaps the reason is not the boiler, but an installation error. To find out, inspect all connections to ensure they are connected correctly. It could also be:

Depressurization of the air duct . Air enters not only through the main hole, but also through the hole. Therefore the noise increases.
Incorrect burner placement . Perhaps it has shifted and cannot cope with burning the entire volume of gas. You need to install it in place.

Gas boiler whistles

If the product whistles and squeaks, you need to find out where the sound is coming from. What to do:

Turn off the gas supply.
Open the mixer in the “hot” position.
Did the whistling intensify? This means that the problems lie in the water path. The main reason is scale deposits on the heat exchanger parts or pipes, or blockage. It is necessary to clean all the elements in order to restore the performance of the equipment and eliminate the cause of the whistling. Using a reverse flow of water can clear clogged pipes.

If the whistling sound disappears when you open the tap, the problem is in the gas path. There is probably a defect in the valve that controls the flame intensity. Whistling may appear when the operating power is increased. Try turning the control until the sound goes away. Does not help? Then the problem is that the tract is clogged. The device needs to be disassembled and cleaned.

If you notice similar problems in your equipment, you can try to solve the problems yourself. But it is better to contact a service center, especially with a valid warranty card. Employees will repair or remove faulty equipment.

How to eliminate whistling, popping, humming in a gas water heater

The operation of a gas water heater is always accompanied by certain sounds. Usually this is the sound of water running through pipes or the burning of a fire. But it happens that the device begins to make non-standard sounds: whistling, popping, clicking, etc. If this starts to happen, you need to quickly figure out why the gas water heater is making noise. The reasons may be different.

Popping sound when turned on

If you hear a pop when you turn it on, this indicates a problem with the gas supply. Each device has a working area in which fuel accumulates when the equipment is turned on, as well as its connection to air. If the volume of accumulated gas coincides with the manufacturer’s calculations, then there will be no extraneous pops. And if gas and air accumulate in excess, this leads to a small explosion accompanied by a loud bang. This action not only produces an unpleasant loud sound, but also increases the risk of damaging the chimney. You can solve the problem by calling a technician to your home or by yourself if you understand the design of the device. You can fix a geyser with your own hands like this:

turn off water and gas;
remove the body;
inspect the gas pipeline approaching the burner;
if necessary, clean parts from soot and soot;
inspect the condition of the injectors; if there is contamination, clean the elements.

When turned on, the gas water heater slams, what should I do?

To install gas equipment, it is better to contact a specialist, and you need to monitor the work yourself. If you notice that the gas water heater is clapping or making unusual sounds, do not delay it, contact the service center immediately. In this article we will tell you why equipment makes noise.

Why does the gas water heater crackle and bang?

The only reason that popping noises are heard when you turn on a gas boiler is excessive gas accumulation. For normal operation, it mixes with air and, when in excess, makes a loud noise. If gas fills the chimney, there may be an explosion .

To solve the problems, you need to figure out what is causing the fuel to accumulate. Before starting the inspection, turn off the gas and water supplies.

Why do speakers with piezo ignition turn on with a bang:

There is a blockage in the chimney, therefore there is no or reduced draft.
The inlet valve that releases gas into the system is deformed.
The wick light deviates to the side.

In recent electronically controlled models, the following could happen:

The batteries are low.
The water switch is broken.
The spark plug does not fire.

For repairs, contact only a specialist. But you can do an examination and try to find out the cause yourself.

Poor traction

To check its presence or absence, light a candle or match. Bring it to the inspection hole on the body or the chimney outlet. With normal draft, the fire should deviate to the side; with medium draft, it should tremble slightly and deviate slightly. In its absence, the flame will burn evenly. Then when you turn on the hot water, the device may clap.

If you find a lack of traction, contact a specialist. It is dangerous to continue using the column.

Why does craving disappear:

Blockage . Debris gets into the chimney and becomes contaminated with soot, which eventually clogs the passage. You can clean the hole yourself if the blockage is shallow. If not, you will have to call utility services.
Poor ventilation . Often, after installing plastic double-glazed windows, natural ventilation is disrupted. And since air is needed for traction, work is slowed down. The solution is to install a ventilation valve.
Strong hood . It happens that the fan delays the exhaust, not allowing it to exit upward. Therefore, it is better to turn off the hood while the equipment is operating.

The batteries are low

Some speakers are equipped with an electronic ignition system. When you open the mixer, the batteries fire and give a spark, after which the burner turns on. A similar function is implemented in some models “Neva”, “Oasis”, “Electrolux” and others.

How to proceed:

Discharged batteries do not work when igniting. You may hear something clicking or cracking. To fix the problem, just replace the batteries.

Check the fluid pressure regulator. It is triggered when water is supplied and sends a signal to the electronic module to start ignition. The element may be giving incorrect readings, which is why the power is not being activated. The regulator is checked for serviceability with a multimeter. If there is a problem, replace it.

The spark plug moved. Due to temperature changes, the part moves. The spark plug is held in place with one screw. Tighten the screw to the desired position, check: if the candle lights the first time, everything is in order.

The jet (injector) is clogged

Devices with mechanical piezo ignition are ignited by a wick. If it becomes clogged, the column will not work. You need to remove the equipment casing; it is secured with two screws. Find the wick and clean its jets with wire.

There is a burner next to the jets, which could also be clogged. For this reason, the speaker makes noise, pops and shoots. The burner is cleaned with a brush.

It can also pop due to large impurities in the gas. You can ask your neighbors, perhaps they have encountered a similar problem.

If after cleaning the heater's operation is restored, the operation was successful. Otherwise, you need to contact the service center.

The speaker is noisy and buzzing

If the gas water heater is noisy, then most likely the reason is:

poor traction;
lack of ventilation;
wick contamination.

The cause of noise when heating water is often a lack of draft . Therefore, if the gas water heater makes noise during operation, first of all check the presence of draft in the chimney. This can be easily determined by using a lit match or lighter, which is brought to the inspection hole of the chimney or its hatch:

if the flame is drawn into the chimney, then there is draft;
if the fire does not move, there is no draft.

If there is no draft, the chimney should be cleaned. During operation, it becomes clogged with soot and debris.

Read here Geyser does not work - what to do

Lack of air in the room can cause noise . Most often this happens if the owners replaced the old frames with plastic ones. Their seals interfere with natural ventilation in the room. In this case, to stop the noise, it is necessary to increase the air flow.

Causes of various noises and their elimination

When operating a gas appliance, you may hear a specific noise or crackling sound. To understand why your geyser is noisy and to identify the cause, first inspect the device and listen.

As a rule, every gas appliance makes noise during operation. This occurs when gas is burned, which is supplied under pressure into the combustion chamber.

The reasons for breakdowns of modern gas instantaneous water heaters can be very different. Some of them can be fixed on your own, while others will need to be repaired by calling a specialist.

In a poorly ventilated room, these sounds may be heard more strongly. No worries. These sound waves can also be formed during the supply of water, and the crackling sound that comes from the column occurs when metal elements are exposed to an open flame or occurs during ignition from a piezoelectric element.

When hot water is supplied, slight vibrations may occur. They are formed as liquid passes through the system. To reduce the vibration level, it is enough to adjust the water pressure using the valve. By selecting the desired position of the valve, the noise will disappear.

Next, we'll look at the most common problems and determine what causes different types of noise and how to deal with it.

Problem #1 - loud bang when turned on

If you hear a specific loud bang when you turn on the hot water, while the column may vibrate and oscillate strongly, then most likely the gas supply system in the working compartment is faulty. This is due to the accumulation of a large amount of flammable mixture, which does not have time to ignite in time. The accumulated gas creates excess pressure and as soon as it ignites, a small explosion occurs with a characteristic loud bang.

Such circumstances can lead to destruction of the chimney structure, the column itself, or to more widespread destruction. Therefore, you should immediately find out the cause of the problem and fix it. It is best to contact gas service company specialists who will diagnose and help quickly resolve this problem.

If the gas water heater does not work and does not ignite, then the gas burner may be faulty - to solve the problem and restore the functionality of the burner, it is necessary to clean the nozzles from soot and dust

If you want to try to cope with the task yourself, then you can try to inspect the condition of the parts inside the device.

To do this you need:

shut off the supply of fuel and water to the system;
remove the upper part of the gas water heater box;
if traces of debris, dust and soot are visible, then it is necessary to clean the surface thoroughly;
if there is a lot of soot inside, most likely the injectors also need to be cleaned;
further inspect the condition of the electrodes, clean or replace if necessary.

The cleaning process is quite labor-intensive and complex. Therefore, if you are not sure that you can repair the equipment yourself, it is better to leave this idea. Contact the gas service or specialists so as not to endanger your life and the health of other people.

Problem #2 - the speaker makes loud noise and hums

Usually this phenomenon is associated with weak draft in the chimney or ventilation shaft. To find out whether the pull is in order or not, just light a match or lighter and bring it to the hole.

With proper operation and normal draft, the flame will immediately begin to be drawn inward, but if the flame does not deviate, then it is necessary to start cleaning the chimney channel from soot and dirt

If there is insufficient ventilation, increased noise will also be heard. This usually happens when installing double-glazed windows. They make natural ventilation of the room impossible. In this case, it is necessary to take care of upgrading the ventilation duct or installing a supply valve on the windows or in the wall.

Problem #3 - there is a crackling sound when the device is operating

If you hear something crackling in your gas water heater, then most likely the nozzles inside the device are dirty. Gas is supplied through them and a flame is formed, heating the heat exchanger. To find out and clean the jets, you need to disassemble the equipment in the sequence as described above.

If the column crackles and does not light up, then it is necessary to check the functionality of the batteries; perhaps they are simply discharged - if necessary, replace the old batteries to restore the operation of the gas boiler

Now let’s figure out why the household gas water heater clicks.

So, in speaker models with electric ignition, there may be several reasons for the crackling sound, namely:

Batteries. Models with an electric ignition type usually run on batteries. As soon as the batteries lose their capacity, the gas does not ignite immediately or does not burn at all. And the clicks come from a piezoelectric element, which will operate until the flame ignites. To fix this problem, simply replace two batteries.
Failure of the sensor that controls the gas flow. Often, under the influence of condensation, the sensor metal oxidizes. In this case, you can try to clean the oxides. But for the device to work correctly, you need to buy a new sensor.
Spark plug deformation . If the wick has moved, this may be another reason why the heating device does not work. As soon as you place the candle in its original position, the flame will light up.
In some cases, the retarder ball - the ignition mechanism - may not work . Most likely the cause will be a stuck ball. The simplest solution is to remove the product and shake it to free it or otherwise clear the jam.

A loud hum and vibration may indicate that an error was made when connecting the gas equipment. To find out the reason, check how the gas and water pipes are connected. Maybe some nuts need to be tightened. In addition, loud sounds and vibrations can be caused by depressurization of the air duct. Fix the problem and the noise will stop.

If the gas burner that heats the heat exchanger has moved to the side, this may cause incomplete combustion of the fuel. You may smell gas. Return the burner to its original position and the noise will disappear.

Checking the functionality of the gas burner and eliminating the malfunction by replacing the ignition wick

Problem #4 - the gas water heater whistles

Whistling sounds can come from different places in the gas appliance and gas network. Most likely, the reason why a household geyser whistles is the place where the pipes are connected. This means that a gas or water pipe is making noise. First you need to determine where the whistle is coming from.

Then it will be easier to figure out why this happens:

First of all, you need to block one of the inlet pipes. For example, shut off a gas pipe. We recommend that you familiarize yourself with the causes of noise and vibration in a gas pipe.
Next, try opening hot water.
If the whistling does not stop and becomes even louder, then you need to inspect the water supply system. Most often, this problem occurs when the equipment is used for a long time. During the process of heating water, a hard limescale deposit (scale) forms inside the heat exchanger. This helps to reduce the diameter of the holes, thereby making it difficult for water to pass into the system. To fix the problem, you need to clean the heat exchanger with a special solution or replace it with a new one.
If the dispenser stops whistling when you open the tap, then the problem is in the gas supply system. The flame control valve may have failed. To check, try reducing the gas supply. If the whistle does not decrease, then it is necessary to disassemble the device and clean it.

To prevent scale accumulation in the heat exchanger, experts recommend installing water filters at the cold water inlet. This way you can reduce water hardness and increase the service life of the heat exchanger. The cost of a new one is rather high, so you need to monitor its condition.

So, if you notice that the water pressure is very low, then most likely your filters are clogged or the heat exchanger is clogged.

If the gas water heater is noisy and vibrates, and the water pressure in the tap is very weak, then a large amount of scale has probably accumulated inside the copper heat exchanger. But the radiator can be cleaned at home

Problem #5 - the device clicks and does not turn on

If, when you turn on the hot water, the column starts to click and does not turn on, then the reason may be a faulty fan. It is designed to discharge combustion products into the ventilation pipe. Typically, such models are installed in apartments of multi-story buildings, and in houses where it is not possible to build a chimney or ventilation shaft.

If the fan is faulty, you will hear the piezoelectric element clicking, but the gas supply valve will not operate, and accordingly the device will not work.

Causes of malfunction:

The fan blades are clogged with dirt and debris . To find out the cause of the breakdown or clean the part, you need to inspect the device. To do this, remove the protective cover and look at the condition of the fan. If it is clogged with dust and debris, clean it and, if necessary, lubricate it with special oil.
The winding burned out . If the fan does not show signs of life, then most likely the gearbox winding has burned out, in which case it is necessary to replace the device with a working one. Also, stopping can occur due to oxidation of contacts. Check and, if necessary, clean the connection contacts.

If you cannot find or fix the malfunction of your column, then do not waste time and call specialists who will perform all the necessary actions to solve the problem.

To find out whether the fan that removes combustion products to the street is working, you need to remove the protective casing of the gas water heater and inspect the turbine

Causes of noise in a device with electric ignition

The causes of noise in a gas water heater equipped with electric ignition may be the following:

The batteries are discharged - in this case, the ignition does not work well and the gas-air mixture is difficult to ignite. This problem can be easily solved by replacing the batteries.
The sensor that controls the water supply is broken. Often problems are associated with the oxidation process of contacts. Basically, this sensor is not collapsible, so you have to replace the element with a new one.
Problems with the mechanical ignition retarder. The presence of problems in this unit is determined by removing it and shaking it. During this procedure, the noise of the ball moving inside the retarder will be heard. If there is no sound, this indicates the ball has moved. You can fix the problem and return the ball to its place using a thin wire.
A spark plug malfunction prevents an electric spark from appearing. It mainly moves after repeated heating and cooling processes. It is necessary to return the spark plug to its place, after which the possibility of a spark will be restored and the extraneous noise will go away.

The speaker whistles

If a gas water heater whistles, you should immediately figure out which unit the noise is coming from. To check this, turn off the gas tap, and then unscrew the hot water tap. Subsequent actions depend on the nature of the noise:

If after the above steps a whistle appears, then it is associated with the water path. The most common cause is scale deposits in the heat exchanger or a foreign object getting inside the pipe. As a result, the performance of the device decreases. In this case, cleaning or washing the object out of the pipes using reverse flow will help eliminate noise and increase the performance of the column.
If the dispenser begins to operate quietly, it means that one of the gas supply units has failed. This is mainly due to a defect in the valve that regulates the power of the fire. A sign of problems with the valve will be a change in sound when adjusting the flame intensity. The problem may also be hidden in a clogged tract. The whistle is then audible in any case. It is recommended to call a specialist to identify the location of the blockage.

Whistling, knocking, annoying rumble! Why is the gas boiler noisy, is it faulty?

A recently purchased gas boiler operates quietly, barely noticeable to humans. If during operation the unit suddenly begins to make noise, then this is a direct sign of the first malfunctions in the system.

The fan is out of order, the walls of the heat exchanger are clogged with scale, the components of the device are worn out or the boiler is not configured correctly - all these reasons lead to the device beeping, knocking, humming or making clicks.

Odnoklassniki

There are many reasons that cause alarming noise in a gas boiler. Each problem requires a different approach to fix it.

The fan located above the burner is faulty

The fan provides ventilation in the system to remove and exhaust smoke, and also removes residual gas combustion products. A common reason for fan failure is operating time. The longer the boiler operates, the more parts of the system wear out.

Photo 1. This is what a fan looks like in a gas boiler. Its breakdown can cause unpleasant noise coming from the heating device.

Other causes of breakdowns:

The fan is usually located at the top above the burner. Constantly being exposed to high temperatures burns out the bearing lubricant. This causes rapid wear.
The fan is full of dust and residues from gas processing.
Manufacturing defects.

Reference. There are characteristic sounds that indicate a malfunction of the device. Listen to the operation of the boiler. If it makes clicking sounds at short intervals, the cause is the fan.

In order to repair the fan, you should carry out the following manipulations:

First, inspect the fan and clean it from the inside: the main blades are located on the inside of the housing, you need to free them from accumulated dust and dirt, and then lubricate the bearings.
If the problem has not been solved and the boiler is still noisy, you can replace the valves with ball valves or install a rubber gasket.
If the previous measures did not help, then you should reinstall the cooler. To do this, you need to call a technician and replace the worn-out device with a new one.

Scale in the heat exchanger

A heat exchanger is a boiler component that plays the role of an intermediary between the thermal energy of the gas and the water that is heated by it. Because of it, scale appears and lime accumulates both on the walls of the radiator pipes and in the entire heating system.

Photo 2. Heat exchanger from a gas boiler with scale formed on it. Because of this, the heating device makes noise.

This often causes a narrowing of the passage for water, which provokes the appearance of steam and small bubbles in the system. Scale reduces the wear resistance of equipment and the efficiency of the device. The breakdown is noticeable within 15-20 minutes of constant operation of the gas boiler.

Important! An alarming sign that a lot of lime deposits have accumulated in the heat exchanger is a characteristic sound. The device hisses, whistles, and howls like a kettle when boiling.

Deposits lead to excessive overheating of the heat exchanger walls, which causes them to warp.

To clean the device from contaminants, you should rinse the heat exchanger, pipes and other parts of the heating system with a chemical solution.

Reference. In household stores there are a large number of chemicals that can quickly clean any scale. To make the right choice, consult with a gas service technician.

First remove the heat exchanger itself. Next, remove the casing and unfasten the pipes connected to it. The chemical solution is poured into the device for 2-5 hours. If the design of the device is quite complex, then to remove it yourself, use a flexible hose.

Other causes of noise

Sometimes the cause of noise in a working geyser is not a breakdown, but loose communication connections or a poorly secured element. Therefore, if extraneous sounds appear, it is worth checking the tightness of the parts and pipeline connections. You can also see if anything has gotten into the device body. Perhaps after the last disassembly they forgot a bolt, electrical tape or other item.

When noise appears in a gas water heater, it is important to determine the cause and solve it as quickly as possible. A hum is the first sign of a problem with the device. If the problem is not corrected in time, it will gradually lead to more serious consequences. As a result, you will have to buy a new gas water heater instead of small repair costs.

Why does the gas water heater hum when hot water is turned on?

A working flow-type gas boiler operates almost silently. The appearance of extraneous sounds indicates that one of the components has failed and needs serious repairs. The cause of the malfunction is identified by the nature and intensity of the noise.

Frequent signs of breakdown:

the gas water heater hums when hot water is turned on;

a characteristic whistle appears;

Each manifestation has its own reasons. A breakdown requires immediate repair, as it can cause an explosion or complete failure of the water heater.

Why is a gas boiler or water heater noisy?

The consumer buys and installs high-quality gas equipment at home, and it will be an unpleasant surprise for him when the gas boiler or water heater makes noise. Does this always mean a major overhaul of equipment? Can a home repairman eliminate the cause of the noise himself? What to do if the boiler makes noise when you turn on hot water. The equipment still has a warranty period, everything is clear here. The Neva speaker is noisy - you need to take your purchase to the store and exchange it for a new one. The warranty has expired - there is only one way out. In this case, you will have to call specialists from a gas boiler repair bureau.

Causes of noise from a gas water heater or boiler

The Baxi boiler makes noise and prevents me from sleeping at night. Extraneous sounds when turning on the equipment are signs of a malfunction of the heating system.

Why does the speaker whistle and hum?

First you need to determine what exactly caused the appearance of extraneous sounds. To do this, turn off the gas and open the hot water tap. If the whistle does not go away, then the breakdown is due to a faulty water supply system. There are several reasons for the problem:

debris got inside the heat exchanger or water regulator: rust or sand;

If the dispenser operates quietly when the gas is turned off and only hums when turned on, it means that one of the gas control valve units has failed. In the case of automatic water heaters, a whistle from a gas water heater indicates the following:

scale in the heat exchanger;

The gas valve has failed.

The problem can be solved by cleaning the pipes. You can clean it yourself using improvised means and special chemicals. A boiler that whistles when hot water is turned on may also be noisy due to failures in the settings of the valve that regulates the gas supply. Usually, third-party sounds stop when a different heating mode is set.

If a semi-automatic gas boiler is noisy during operation, the breakdown may be caused by the pilot burner. A characteristic sign: the column hums if the water is not turned on. The malfunction is due to dirty jets. It's actually the igniter making noise. After cleaning, all unusual sounds will go away. The boiler will operate normally.

The geyser goes out - why does a gas water heater light up and go out?

Why does the speaker go out after turning it on?
Why does the speaker go out during operation?
Turns off during shower mode - reasons
Turning off the column when mixing water
Why does the column not go out after turning off the water?

You can determine why the gas water heater goes out and fix most problems in the water heater yourself. Malfunctions are manifested in the following:

the flame goes out immediately after switching on;
the column goes out during operation;
attenuation occurs when switching to the “shower” mode or mixing hot water with cold;
the burner continues to work after turning off the water.

In each of the described cases, malfunctions are caused by different reasons.

Why does the speaker go out after turning it on?

There are several reasons for the attenuation. To determine the malfunction, you need to pay attention to the duration and intensity of the flame. The following signs will help identify the cause of malfunctions:

The column and wick light up and immediately go out - after repeated starts, the water heater does not start. Cause of failure: failed servomotor or solenoid valve. Cleaning the burner and jets will not help. The malfunction can only be eliminated by replacing broken components.
The burner turns off after a few seconds of operation, when turned on again the flame burns longer, after 5-6 starts the column starts working normally - the reason: a malfunction of the ignition system, more precisely the flame ionization sensor or overheating relay. To eliminate the malfunction, change the module or move it closer to the flame.

If the gas water heater turns on and immediately goes out, the breakdown can be eliminated by replacing the servo drive, solenoid valve or flame ionization sensor. Repair work requires the involvement of a specialist.

Why does the speaker go out during operation?

Another common malfunction is that the flame does not die out immediately, but after several minutes of operation. When figuring out the cause of the malfunction, you should pay attention to the following signs:

duration of operation after switching on;
whether the malfunction is eliminated when the water heater is restarted.

The main reasons that a geyser goes out during operation:

The chimney is clogged - combustion products have time to escape from the combustion chamber. A characteristic manifestation: the igniter and burner go out. The speaker turns on with a bang. Troubleshooting: cleaning and restoring the smoke channel.
The supply and exhaust ventilation and the gas heater in the kitchen are turned on at the same time - while the water heater is operating, the hood must be turned off or set to a lower power. Burner extinction occurs due to the accumulation of flue gases, which cannot escape into the channel due to insufficient draft. The speaker turns off automatically after a short period of operation.
The overheating sensor in a gas water heater is triggered - the block consists of two metal plates that are triggered when heated. The reason for the shutdown is the oxidation of the contacts between the control module and the fuse. You can check the temperature sensor by moving it closer to the burner. If this is the reason, the column will begin to work temporarily without failures. Protection against overheating of the geyser is an important part of the internal structure. It is prohibited to turn off and start the water heater without a module.
The radiator is clogged - the heat exchanger has fins. When using the speaker for a long time, debris accumulates between the plates. A characteristic sign of a clogged heat exchanger is a change in the color of the flame to yellow. The problem can be resolved by washing the coil with warm water. At the same time, clean the igniter using a wire or a brush with coarse bristles. Spontaneous shutdown during operation should stop.
In models with piezo ignition, it is important that the wick is constantly burning. If there is insufficient draft (the reasons are given in points 1 and 2), the igniter goes out, which leads to the column turning off.

After eliminating the described disturbances related to air circulation in the room and the need for good draft, as well as replacing the overheating sensor, the water heater will continue to function normally. The speaker will stop turning off regardless of the duration of operation.

Turns off during shower mode - reasons

The automatic column works as follows:

a gearbox is used as a trigger, internally divided into two parts by a membrane;
the first section is connected to the hot water supply - after filling the block, water enters the coil located above the burner device;
in the second part there is a rod that opens the gas supply;
water entering the gearbox presses on the rubber gasket;
the membrane presses on the rod and opens the flow of gas.

When switching to a shower, the pressure in the DHW decreases. When the water pressure is low, the column turns off. Installing a special pump that stabilizes the pressure in the water supply pipeline will help solve the problem. You can additionally check the condition of the mixer. The burner may turn off due to debris accumulation in the shower head.

Turning off the column when mixing water

The instructions for the water heater indicate that it is extremely undesirable to dilute the hot water supplied by the water heater with cold water.
It is recommended to immediately set a comfortable heating temperature. The geyser goes out when cold water is turned on due to decreased pressure in the pipeline. Inside the water heater there is a protection system (water unit) that prevents water from overheating. When the water pressure is low, the gas supply is turned off and the flame goes out.

If this happens at normal pressure, it is necessary to change the gasket of the gearbox (water unit). Membrane wear occurs due to long-term operation of the water heater. The gasket may lose elasticity due to poor water quality.

There are two ways to solve the problem:

replace the membrane;
Initially set the required water temperature that is comfortable for washing.

Proper operation of the water heater will help solve the problem associated with shutting down when mixing hot and cold water.

Why does the column not go out after turning off the water?

Another common problem. The cause of the malfunction is the low quality of water entering the column and the resulting disturbances:

The rod in the water unit (gearbox) gets stuck - the reason: the appearance of rust, as well as the weakening of the spring that returns the device to its original position after turning off the water. If the geyser does not go out after turning off the water, within just a few minutes the liquid will reach the boiling point and rupture the heat exchanger tubes.
Damage to control valves - the water heater has a valve that opens the gas supply to the burner. The unit turns on and off simultaneously with the opening/closing of the water tap. After the valve fails, gas is supplied to the burner continuously. When the hot water tap is closed, the regulator does not operate. It is necessary to completely shut off the gas supply and call a technician.

If the gas water heater does not go out when the water is turned off, you should not try to repair it yourself.
The breakdown requires a qualified technician to fix it. avtonomnoeteplo.ru
