Major breakdowns during operation of the gas water heater Neva 4513

Overview of repair options

The devices are equipped with modern automation, they are protected by multi-stage systems and provide increased safety during operation.

The Neva 4511 geyser is considered one of the most popular; you can repair this equipment yourself if you read the information below. But experts do not recommend undertaking such work on their own; this especially applies to those people who are not very well versed in such equipment. It is not recommended to do this if the warranty period has not yet expired, because independent repairs will void the manufacturer’s obligations. But if the device was purchased quite a long time ago, then it is worth considering that its design is simple, so any home craftsman will be able to handle the repair.

Refusal to ignite

The Neva 4511 geyser, which you can repair with your own hands if you refuse to ignite, is a budget and fairly simple model. Quite often, the problem mentioned above can be caused by the fact that the ventilation system suffers due to lack of draft. If this is the case, then the problem can be eliminated by cleaning the channel. If the batteries are low, a problem may arise with the power supply; this issue can be resolved by simply replacing it. The gas water heater "Neva 4511", a review of the faults of which is mentioned in the article, may experience failure to ignite due to low water pressure in the system. In this case, the consumer can wash the filters and also clean the device from combustion products. If this approach does not solve the problem, then you should contact your utility service with a question about low pressure. If the Neva 4511 gas water heater still does not light up, you can carry out the repair yourself by adjusting the temperature of the coolant. This solution is relevant if the balance between hot and cold water is incorrect.

External factors of column inoperability

1. Incorrect connection to the water supply line outlet. As a result, the column does not work after installation or after plumbing work. Check that the pipes are connected correctly: the outlet pipe is marked in red and it is connected to the hot water pipeline.
2. Low water pressure in the system, as evidenced by a weak stream of water from the tap.

The problem of low water pressure is relevant for residents of the suburbs, whose water pipes receive water from water towers. In this case, when buying a gas water heater, you need to study the equipment parameters as carefully as possible, namely, the minimum permissible water pressure level.

It happens very often that the water pressure drops due to a clogged filter, which is located in front of the column. This can be checked by comparing the stream of water in the cold and hot water tap, and if the stream in the cold water tap is not thin, but normal, then check the filter. Cleaning it will eliminate the hot water problem.

There are also cases when, when the water heater is turned on, the water flows barely warm, a little time passes and the water heater turns off completely. This is all due to a defective mixer. It adds cold water to hot water, which causes the water in the column to overheat and trigger the shutdown system. To make sure of this:

• The tap supplying water to the water heater should be closed.
• Open hot water. If the water runs out, it means the mixer is faulty.

What else needs to be taken into account when troubleshooting a gas water heater?

1. The gas supply filter is clogged due to which the dispenser does not receive fuel to operate. The problem can be resolved by cleaning the filter. If this type of breakdown occurs during gas supply work, the cause may be airing. The air trapped in the pipe must be released when the gas valve is opened, and then the operation of the column will be restored.
2. Deterioration of cravings or its disappearance. This problem most often occurs with columns that have a pilot burner, in which it is not the draft sensor, but a tube that connects the chimney to the ignition point. If there is no draft, combustion waste passes through this tube and goes to the igniter, which leads to its extinction. In electric ignition water heaters, the draft is controlled by a temperature sensor.

Check the kitchen for leaks. If there are plastic windows or a plastic door, any of these must be placed for ventilation. A specialist checks the chimney for operability. Even when the column is turned off, draft must be present, since the chimney works like a ventilation duct. The technician brings a small sheet of newspaper to the inlet of the chimney and, if the sheet does not deviate, then the pipe requires cleaning. There are many reasons for its clogging, including soot, garbage and even bird nests.

By the way, smoke can linger in the chimney due to an antenna installed on the roof directly above the chimney or some other object.

Turning on the speaker with extraneous claps

Most often, this problem is caused by clogged ventilation; it may also happen that the supply batteries have expired or the fuel is supplied too intensively. Sometimes characteristic pops occur when the nozzle is clogged. In any of these cases, you need to contact a specialist. The only exception is replacing batteries or cleaning ventilation ducts.

The problem of inefficient water heating

If you have a Neva 4511 gas water heater installed in your house, you can repair this equipment yourself. This also applies when the water is not heated as efficiently as required. If the equipment turns on, but the water temperature does not reach the required level, then the equipment simply may not meet the power needs of the consumer. The second assumption is that the column is clogged. In this case, the equipment loses performance. To solve the issue of inefficient water heating, you can adjust the coolant supply tap or seek the help of a service center specialist, he will be able to clean the equipment.

Temperature sensor malfunction problem

The gas column "Neva 4511" (automatic) is protected by a multi-stage system, but even then it happens that the column does not ignite. The culprit for this is the bimetallic temperature sensor; it is designed to protect the equipment from overheating. The malfunction usually manifests itself in the fact that the burner goes out, and the column itself works for a certain time, but then stops, and attempts to ignite do not achieve results. After 20 minutes, the column can be turned on again, the burner will light up, but after the same period of time it will go out again. This may be caused by the sensitivity of the equipment. This case is guaranteed, in addition, the problem occurs only in summer or winter, it occurs at too low or too high temperatures when the windows in the kitchen are closed. In these cases, the temperature in the room is elevated and the equipment is not cooled. If you have a Neva 4511 gas water heater installed, a malfunction in the sensors can also be expressed by a chaotic shutdown of the device. Sometimes it doesn't light up at all. The behavior may indicate deterioration of the sensor conductor insulation. A short circuit to the housing causes the safety valve to operate. In this case, it is useless to call gas workers, since the problem is not related to the gas part. There is also no way to solve it yourself, so it is best to contact a service center.

Possible malfunctions when using geysers Neva Lux 5514

_______________________________________________________________________________

The automatic gas water heater Neva Lux 5514 is in operation. Could you please tell me why it began to heat water unsatisfactorily? What operations need to be performed to fix the problem? Firstly, the heat exchanger is clogged with dirt. An increase in deposits on the walls of the heat exchanger creates an obstacle to proper heating of the water, and the device begins to weakly heat the water. Therefore, we advise you to clean the heat exchanger. Option two is regular overheating of the heat exchanger. This is due to improper operation of the equipment. An increase in temperature entails the formation of scale, which slows down the heating process of the liquid. In such a situation, change the heat exchanger. We have a gas water heater of this model in our private house. After four years of operation, the heat exchanger leaked. The repair did not help, and after three months I purchased a new unit. The installer recommended maintenance and cleaning every year. I cleaned it and did that. As a result, this device worked for 4 years, and the reason for the breakdown was the same - wear of the heat exchanger. Why might this happen? There may be problems with water, causing the heat exchangers to fail. At the dacha there is a model of this exact brand connected. I can’t figure out why in some cases the water gets too hot? What is the problem? Apparently the problem is with incorrectly installed regulators. It is necessary to make adjustments for the summer season. Use the gas flow adjustment knob to reduce the gas on the burner block, and then add a water flow to the water heater. There is a problem with the Neva Lux 5514 battery-powered flow-through gas water heater. The wick starts to burn, I leave it in this position for about 5 minutes. Then I switch to the operating mode, but the unit goes out. What does this depend on? Try removing the housing, unscrewing the tube that supplies gas to the wick, and rinsing it. In theory, such an event is recommended to be carried out annually, preferably at the end of summer, because the windows are often open and dust will penetrate into this tube. Help me figure out why the device sometimes performs the heating process unsatisfactorily. What are the solutions? Presumably, the burner has an unstable flame, which indicates a membrane malfunction, and the pressure of the rod to the gas valve is very weak. You need to remove the water block from the gas fitting. Then unscrew the cap from the water block and check the membrane for deformation, and if it is damaged, install a new one. A year ago, a gas water heater from the above company was connected to the house for heating. This week there was a problem with the ignition. When a request for DHW arrives, the wick is ignited. It lights up and immediately goes out, and then the water heater starts up again. And so on for about 2-3 attempts. The unit then operates normally. I just can’t figure out why the pilot light cannot ignite the main burner? What's happened? Now the column functions as follows. A spark is formed which ignites the fuse. After this, the spark disappears, the wick burns for a short time and goes out. The device re-discharges the spark, the wick is ignited, the spark stops flowing, and after some time the main burner lights up. There appears to be a problem with the ionization sensor. First, you should inspect it. Of course, it is advisable to install a new one, but if you can’t, you need to clean this one with sandpaper. Also clean the burner using a metal brush. After these measures, it is important to check that the burner has a blue flame and not yellow. In addition, the fire must reach the ionization sensor. We installed and launched the Neva Lux 5514 gas flow-through water heater six months ago. But when winter comes, a problem often arises in operation, in particular, low gas power, and, moreover, the gas supplied is not clean. How can I fix the problem? There is an adjusting bolt at the bottom of the device. When the burner is turned on, it is necessary to turn it to the left and set the desired flame value. When summer comes you can turn it back. If such a procedure does not correct the situation, most likely the pressure in the gas pipeline is indeed unsatisfactory. The gas water heater has been operating in a private home for almost 4 years. The other day the pilot light stopped turning on, and when you try to light it with matches, the flame immediately goes out when you turn the dial to the heating position. What to do? I observed the same problem. The specialists explained that the thermocouple needed to be replaced. Tell me about the malfunction of the gas water heating column. If you open a hot water tap, the water heater goes out. I tried cleaning the thermocouple, but to no avail. The membrane was checked and found to be suitable, although it was replaced with a new one anyway. The water pressure decreases, but not significantly. How to find and fix the problem? The traction is probably weak or the traction sensor is broken. You should check this out. Sometimes a curved pipe is installed in place of the draft sensor on top of the water heater. It supplies the air needed for combustion. If the draft is disrupted, it is not air that enters the tube, but smoke. Because of this, there is a lack of oxygen for the burner and it goes out. Additionally, check the pilot flame. It should completely cover the thermocouple. When this does not happen, it means the thermocouple heats up little and stops sending a signal to ignite the main burner. The other day a serious malfunction appeared: the automatic gas water heater Neva Lux 5514 began to turn off during operation. Could you tell me what problems there might be? Presumably, there is a malfunction of the membrane in the water unit. It has become deformed or worn, so it needs to be replaced. We also advise you to inspect the solenoid gas valve, since it contains an electromagnetic coil that could have broken. The coil cannot be repaired, only for replacement. Please advise on a faulty gas water heater. 3-4 minutes after ignition, the device finally goes out, and subsequently the ignition device has to be lit only with matches. What could have happened? Perhaps there is no draft in the chimney, which is why the draft sensor is triggered and the device goes out. It is necessary to check the chimney duct. Overheating of the water in the heat exchanger may also occur when the temperature reaches 90 degrees. In this case, the overheating sensor will turn on and turn off the unit. To reduce the water temperature, turn down the gas on the main burner using the regulator. I would like to know why a gas water heater lights up and then immediately goes out? How should this failure be resolved? The first reason can be considered a clogged chimney. Most likely, a significant mass of soot deposits has accumulated inside it, and combustion products are removed with difficulty, which is why the draft sensor is triggered. The thermocouple opens and the flame of the device goes out. The second reason is a strong wind, which can extinguish the flame of the column if there is a draft in the room. Accordingly, the protection mechanism is activated and blocks the flow of gas. Sudden gusts of wind should not be allowed. But there is no need to completely limit the access of fresh air, since the equipment must operate with an open window. If there is no fresh air, the draft will be poor and the flame will go out. The house is equipped with a Neva Lux 5514 automatic gas water heater (14 liters). Please tell me why she began to heat the water excessively? What steps do you need to take to resolve the problem? The suspected cause is high blood pressure. Set the water heating temperature regulator to maximum flow, and set the gas regulator to the minimum gas flow to the burner position. Such adjustment can help reduce the temperature of the water leaving the column. What is the reason why ignition slows down and the gas burner slams loudly? The pilot spark does not reach the main burner, or it is insignificant. It is recommended to clean the igniter and nozzle. After this, carry out configuration operations. Problem with gas water heater. I try to start it, a spark is produced, but the igniter does not ignite. How to fix it? The igniter nozzle is clogged with dirt. You need to cleanse. The ignition electrode is in the wrong position. Set it up. Presence of air in the gas pipeline. Remove the air. We installed and started up the Nevalux 5514 geyser. The problem is that the device starts to work, but then goes out after two seconds. Most often this happens at night, when the unit has been resting from work for a long time. In addition, if it heats water regularly, it no longer turns off. If you press the microswitch for a long time, the water heater lights up and continues to function well for several days. What could this be? There is no need to click the microswitch, just install a new one, since yours is broken. The actions of the unit are approximately as follows. A spark first appears and goes to the igniter. An ionization signal follows, the gas supply to the main burner begins, and the flame lights up. When there is no signal that the igniter is functioning, the main burner will also not start. Your igniter sends a signal, but the main burner does not start. The ignition process is in progress, but there is no signal, so the gas supply is blocked. We advise you to clean the electrode. There is a similar unit. Why does the pilot burner go out during ignition? What kind of malfunction is this? The thermocouple has failed. Needs replacement. The coil is damaged. Change it. A question has arisen regarding the operation of the Neva Lux 5514 14 liter instantaneous water heater. Here's what happened: the pilot burner lights, but the main burner doesn't want to. What needs to be done and how to repair it? Lack of water pressure. Set the required system pressure. You must turn the adjustment knob all the way to the right. Membrane wear. Make a replacement. In my country house I use a speaker. When you turn off the water, the gas burner does not go out. What is the cause of the problem? The gas valve shutter is clogged. Run its diagnostics. If necessary, rinse. The hydraulic valve rod is jammed in the open position. Remove elements, clean, install new ones if necessary. Check the gas inlet pressure. Adjust if necessary. Replace the gas cylinder reducer. I just can’t understand why there is no spark when starting the unit? The wiring of the ignition element has broken. Connect the wiring as required. Igniter malfunction. It is necessary to check this device and replace it. The electrode is faulty. Replace it.

• JUNKERS

The Junkers gas water heater began to malfunction. It works for 15-20 minutes and goes out. You turn the water off and on, the igniter lights up, and after a few seconds it goes out, and you can do this no matter how many times, it doesn’t light up. A little time passes - it works, and everything repeats again. The water pressure is good, as is the gas pressure. What could be the reason?

Replacing the membrane

Before replacing the membrane, turn off the equipment and turn off the cold water and gas. One of the hot water taps opens, which will relieve pressure in the pipes. At the next stage, the column casing is removed, and then the mounting screws, which are located under the decorative overlays. The technician should remove the water regulator; to do this, unscrew the motor nuts. Now you can begin the procedure for replacing the membrane. When repairing the Neva 4511 geyser with your own hands, it is important to note that the element being replaced should not be installed upside down. It is important not to block the bypass channel. Next, you can reassemble the gas water heater, proceeding in reverse order. It is important to install all the gaskets in place, so treat this step extremely carefully, but if you have experience, these manipulations will take no more than 15 minutes.

So, let's begin disassembling and repairing the Neva column:

1. Unscrew the union nuts on the tube connecting the heat exchanger with the water block of the column and remove the tube.

2. Separate the wires on the connectors that fit the solenoid valve (1) and the microswitch wire connectors.

3. Unscrew the screws that attach the gas

column block to the body.

4. Remove the battery compartment (you need to unscrew the two self-drilling screws under the cover). Unscrew the screws that secure the column water block to the housing.

5. Unscrew one self-drilling screw on both sides of the gas column burner and remove the completely water-gas gas assembly with the burner.

6. Now you can easily get to the self-drilling screws that secure the column heater to the housing from below.

7. Next, unscrew the draft meter from the cap.

8. Now let’s unscrew the overheating temperature meter from the heating device.

9 Unscrew the self-drilling screws that attach the cap of the Neva

to the heat exchanger and housing.

10. Unscrew the temperature sensor from the heat exchanger and unscrew the screws that secure the section of the heat exchanger pipe to the column body.

Actually, the large-scale disassembly is done. I hope this article will be useful to you when repairing the Neva .
