Elimination of errors that occur during operation of Kiturami gas boilers

We're sure you're not a fan of unexpected expenses. And you probably don’t want to replace a completely new boiler because of a problem that was not resolved in time. Meanwhile, problems appear even in devices that work for the first day. In the article we wrote about errors in Kiturami gas boilers and their codes. Read it. Even if you do not have heating equipment of this brand, it is better to learn more about it - you will understand whether it is worth buying it in the future.

You will learn to recognize errors in Kiturami boilers. Find out what causes them, in addition to the main reasons. For convenience, we have presented their codes in ascending order. Immediately after them, other failures and problems that do not have codes were indicated. Read the article and you will know what to do if a malfunction occurs.

Boiler errors are determined through codes. They differ among manufacturers. On Kiturami devices, combinations of numbers from 01 to 98 pop up. The decodings are the same for all boilers of this brand that run on gas. They can differ only because of the names of individual modules.

Gas boilers Kiturami

Kiturami has been making boilers since 1962 and produces up to 9,000 units daily. Kiturami produces devices that run on gas, diesel fuel, and solid pellets. Gas boilers are manufactured for fuel in accordance with GOST 5542-2014.

Most products from the South Korean manufacturer have a dual-circuit structure, a closed combustion chamber and are fully automated. The efficiency of the devices reaches 94%.

The Kiturami company uses low-carbon technologies, equips its boilers with a large number of fuses and sensors, and makes compact and advanced internal structures

Popular models of Kiturami gas boilers:

• World Plus;
• Eco Condensing;
• TGB;
• KSG;
• World Alpha;
• Twin Alpha;
• World 3000;
• World 5000.

The power of Kiturami boilers reaches 465 kW, and for wall-mounted models it ranges from 13-35 kW. Their turbocyclone burners operate at low pressure - about 30 mm of air column. Each type of fuel has its own burner models that can operate on the same boiler.

Kiturami appliances have protection against freezing and blowing out the chimney. Heat exchangers in World Plus devices maintain their quality even after long-term use of “hard” water.

Kiturami gas boilers last up to 15 years or more, much depends on the conditions of use. Devices display errors with simple numbering - from 01 or from Er 01. Read about them to quickly fix problems and keep the device in working order.

Error codes 01 – 08

Errors 01 to 03 indicate that the control system does not see the flame or has blocked ignition - before or after starting.

Errors 01, 02 and 03 often appear due to a closed valve - open it and restart the device, at the same time check the air supply to the boiler

Code 01 - no flame. Perform the actions from the list, and if nothing changes, move on to the following points:

1. Open the gas supply valve to maximum.
2. Bleed air from the heating system.
3. Inspect the grounding. The wire may have lost its integrity, or it may have been routed incorrectly. Re-ground to a depth of 30 cm or more.
4. Compare the gas pressure in the boiler with the indicator in the instructions. If there is a discrepancy, call the gas workers.
5. Check the integrity of the ignition wire and its power source.
6. Remove soot and dirt from the boiler burner.
7. Also clean the ignition and control electrodes. Soot and deposits collect on them. Reposition the electrodes according to the instructions if the inclination has changed. Check if they work at all.
8. Check that the gas valve and photocell of the flame detection system are working properly. Replace elements with new ones if necessary.
9. Check the circuit board, connections and wires that go to it. Replace if necessary.

Code 02 - false flame or its defect. Check and, if necessary, replace the photocell of the flame control system. Replace the board if it is broken beyond repair.

Check it for oxidation, open circuit, short circuit. The burner nozzles could cause the electrodes to become dirty. Clean them and put them in the correct position.

Code 03 - the flame appears and disappears for a short time. Check the flame sensor and replace the faulty device. Check the pressure on the pressure gauge. Contact your gas service if the reading is outside the normal range.

The problem may be ventilation. Open windows and doors, inspect the built-in ventilation ducts of the room. The error remains - check the external condition of the boiler fan and determine the resistance with a multimeter. The device could break. Also look into the chimney and remove any dirt.

Code 04 - the temperature sensor of the heating element is not working correctly. Inspect the wires that go to the sensor. Connect the broken wires and clean the oxidized contacts. Check the sensor for an open or short circuit. Inspect the control board. If something happens, contact a service that professionally repairs Kiturami brand gas boilers - they are repaired in many service centers in Russian cities. Replace these components if necessary.

Code 05 - overheating sensor failure. Ring the seismic sensor if your boiler has one. Replace if necessary, but do not remove. Also inspect the overheat indicator itself. Determine the pressure in the system and add water if the reading drops. Take a look at the heat exchanger. If there is excess scale, clean the unit.

Code 06 - fan failure - fan speed cannot be determined.

To fix the error you will need to take seven steps:

1. Inspect the wires that go to the fan. Clean if oxidized. Restore broken contacts.
2. Assess the condition of the fan blades. If there is noticeable wear and tear, purchase a new device.
3. If the differential relay connections are stuck (including after they have come loose), replace the unit.
4. Make sure that the mains voltage matches the required value. If not, install a transformer and an uninterruptible power supply.
5. Clear the chimney of anything foreign.
6. Inspect the fan rotating mechanism.
7. Check the Hall sensor.

Replace any unusable parts.

Code 07 - problems with the chimney. The likely cause is the fan/blower speed being higher or lower than normal. Inspect the unit, remove foreign objects. At the same time, clean the chimney of dirt and condensation.

The error appears due to gusts of wind. If the problem occurs frequently, you will have to change the pipe pattern. You need to design taking into account the wind rose.

Many Kiturami boiler models come with CTR remote thermostats, which make it easier to regulate the room temperature and allow you to set the operating time

Code 08 - problem with the room temperature controller. The error appears when communication with the boiler control unit is disrupted. Code 08 will also appear if the length of the regulator wire exceeds 10 meters. Thermostat cables are sometimes exposed to telephone and high-voltage wires.

First of all, turn off the regulator and check the operation of the boiler. If everything is fine, first try to find a different location for the thermostat and turn it on again. Re-route the temperature sensor cable correctly if nothing has changed. Avoid placement in pipes under the floor.

Error codes 14 – 98

Let's start with similar errors - 14 and 34.

Code 14 - malfunction of the hot water outlet temperature meter. Look for a problem in the sensor itself and its wire.

Code 34 is an error of the same type regarding the hot water supply inlet temperature sensor.

After the DHW (hot water supply) sensor fails, the boiler will continue to heat the home, and regulating and maintaining the temperature of running water becomes impossible

Code 95 - indicates low pressure in the boiler/heating system, i.e. due to a lack of coolant (usually water).

Proceed like this:

1. Check to see if there is water in the boiler and what pressure is in the heating circuit.
2. Check and clean filters if necessary.
3. Look for leaks in heating pipes and radiators. Then, eliminate leaks in the expansion tank and heat exchanger.
4. Take a look at the expansion tank membrane. Replace if stretched or becomes too dirty.
5. Add water to normal pressure.
6. Inspect and repair the air valve on the pipe through which coolant enters the heating system.

Code 96 - the temperature indicator has activated. The temperature rose above the permissible 92...97 °C. The boiler will operate in emergency mode until the temperature drops. When the error disappears, restart your device.

Eliminate the cause of the temperature jump:

1. Clean the heat exchanger from scale.
2. Check and replace the circulation pump if necessary.
3. Ring the thermostat. Buy a new one if repair is not possible.
4. Do the same with the board.

Code 97 - possible gas leak. There could be a leak of natural gas near the burner. Stop the gas supply to the boiler and turn it off. Call the gas emergency service. Error 97 may also appear because air has accumulated in the system.

Technologies used in Kiturami boilers to ensure tightness: protection against water hammer and flue gas penetration in the upper part of the heat exchanger

Code 98 appears on liquid fuel appliances.
Indicates insufficient energy level in the fuel tank.

The Kiturami boiler does not receive signals from the sensor that controls water overheating. The sensor may be broken or the connection may be interrupted. You need to stop the device and contact the nearest service center.

Error code 07 - Fan error

There may be some foreign object in the fan, the rotation speed of the blades is either too high or too low. Strong wind entering the chimney affects the rotation speed of the fan. If this code appears, the smoke exhaust pipe must be adjusted and reinstalled. There may be condensation in one of the elbows. It should be removed. If you could not solve the problem on your own, you need to contact the nearest service center.

Error code 08 - Communication between the boiler control unit and the room regulator CTR-5700 is broken

The length of the wires through which this connection is carried out should be no more than 10 m. Also, the operation of this sensor is affected by devices or wires operating nearby. To verify the cause of the problem, you need to turn off the sensor and check how the device works. If the problem goes away, then you need to install the room regulator in another location. If the problem cannot be solved on your own, you must contact your nearest service center.

Error code 10 - Room remote control dirty

Error code 00 - Malfunction of the room remote control or the wire to it

Press the “Restart” button on the room remote control - restart the boiler.

If you are not 100% sure what exactly the problem is and that you can solve it, immediately contact the service center to diagnose and fix the problem.

Problems in the operation of Kiturami boilers

Not all problems have their own code, so we will consider them separately.

“Network” indicator does not light up - check the power in the outlet and the fuse on the ignition transformer. If there is no voltage in the electrical network, call an electrician; if there is, call the service department.

The indicator on the control unit lights up for insufficient water - there is no water in the device or the level is too low. Damage to the black wire of the boiler and the red cable of the sensor can also cause a problem.

The room temperature sensor works normally, but the radiators are cold - the circulation pump does not disperse the coolant through the pipes or does so too weakly. Inspect the locking parts on the heating pipes. Check the pump itself.

"Overheat" light comes on - the heating system is not working properly. Check her out.

If the problem persists, do the following:

1. Adjust the shut-off valves on the heating pipes.
2. The strainer may need cleaning. Examine it.
3. Check the circulation pump, repair or replace if necessary.

The “Safety” diode lights up - gas enters the boiler burner in small quantities or does not enter at all. Inspect the valves and open them if necessary. The problem remains - call the gas workers.

The pump has been running for too long. The water temperature indicator on the control unit is constantly on - the heating system is not working properly or there are air pockets in it. Release the air.

The boiler takes longer to heat up - look for a problem with the gas pressure and the condition of the filters.

The burner vibrates when turned on - the size of the chimney is not enough for normal gas removal.

The efficiency of the device in terms of hot water supply and heating has decreased - bad water or dirt from the heating system enters the boiler. Chemical treatment of the circuits and heat exchanger will help.

Description of Kiturami malfunctions and repairs

The Kiturami diesel boiler belongs to the economy version and has a fairly long service life. But there are also situations when boilers fail prematurely. The reason for the need to repair Kiturami is their untimely maintenance or the use of low quality fuel.

You can carry out simple repairs of Turbo boilers yourself, but it is more rational to contact service organizations in case of malfunctions.

Rice. 3 Installed Kiturami boiler

Below are the main error codes that the Kiturami Turbo 17 diesel boiler most often experiences:

• when the lights flash “01”, “02” or “03” on the display, it means there are problems in the flame detector and ignition does not occur. In this case, the Turbo boiler should be restarted according to the instructions;
• error “04” indicates that the water temperature sensor is faulty in the Kiturami heating system, and repair in this case becomes inevitable;
• error “08” warns that the route between the boiler and the temperature sensor is very long or a wire break has occurred in some place. Repairs will be required to identify the immediate cause of the operational failure;
• error “95” means the pressure in the heating circuit is too low. The Turbo boiler needs to be energized and the entire heating system inspected for possible leaks;
• error “96” - the mechanism that protects the Turbo system from overheating has activated;
• error “98” - indicates that there is a lack of fuel in the supply line.

Of all the errors described above, “01” blinks most often on the display, but this does not pose a great danger to the operation of the equipment. The Kiturami Turbo 17 diesel boiler is characterized by maximum efficiency. Thanks to the control panel, the boiler control functionality is achieved and room heating is possible in any temperature regime.

In Turbo it is possible to regulate temperature parameters step by step from 45 to 75°C. All information about the operation of the diesel Kiturami Turbo is displayed on the thermostat screen by a self-diagnosis mechanism.

Most often, the Kiturami diesel boiler produces error 01. This happens when there is no stable ignition in the Turbo.

The reasons may be as follows:

• when the screw jams, which serves as a fuel level limiter. The repair consists of replacing the locking element or checking the injection motor;
• when the injection motor fails. It is necessary to check the working condition of the Kiturami motor. If the motor is faulty, then the repair consists of replacing it with a new one;
• when there is not enough incoming fuel, then the level in the tank should be checked; repairs in this case will not be necessary;
• when a foreign object accidentally ends up in the screw gate, it must be removed during the repair process;
• when the photosensor fails, the Turbo repair consists of checking this element for its functionality.

When error code “01” periodically appears on the display, in such cases it is necessary to seek help from the appropriate specialists in order to avoid major expensive repairs.

Carrying out regular maintenance and repairs of Kiturami is a guarantee that Turbo boilers will operate efficiently and reliably. If irreparable damage occurs to a diesel boiler during the warranty period, it will be repaired without the need to pay for such work.

The Kiturami Turbo diesel boiler has excellent characteristics, but you must always remember that failure to comply with the established installation diagram, correct settings and basic rules for handling it in many cases ends in total repairs. If all requirements for use and operation are met, modern technologies for the production of heating equipment Kiturami guarantees each user stable operation of the boiler without the need for repairs and a long service life.

What are the differences between Kiturami heating boilers and what can cause them to break down?

The species diversity of Kiturami boilers affects the troubleshooting technology, so consideration of the types of their energy supply and design features is very important.

According to the type of fuel used, Kiturami boilers are divided into:

• diesel (Turbo, KSO series);
• gas (Twin Alpha, World Plus, KS);
• biofuels (KRM).

Construction of a gas double-circuit boiler Kiturami Twin Alpha

In addition, the company also produces solid fuel (KF), condensing heating boilers that can operate on combined fuels. Regardless of the type of device, they all have similar equipment, which includes 5 levels:

• an air system, which includes a chimney and inlet;
• hydraulics, whose main function is to perform heat exchange of the coolant;
• automatic control, with sensors and regulators;
• the fuel system, through which the fuel enters the injector and is transferred by the pump;
• electrical component.

All these levels interact with each other and provide the technical component (passport) of the device, so they must work uninterruptedly. That is why, if problems are detected, repair of Kiturami boilers must be carried out comprehensively. After all, even if the gear panel sensor shows a system failure, it will not indicate the real reason for the deviations in operation: be it a lack of grounding or a simple lack of fuel.

The main causes of problems include:

• violation of operating rules;
• incorrect installation;
• depreciation of equipment;
• untimely service.

Error codes and malfunctions of Kiturami gas boilers

The operation of gas equipment does not always occur without breakdowns. Therefore, manufacturers have developed a self-diagnosis system. Special sensors monitor the operation of each unit in the structure. In the event of a breakdown, error codes for Kiturami boilers are displayed on the display. Each symbol indicates a specific breakdown. We will show you how to deal with the problem yourself.

Design and principle of operation of Kiturami boilers

The Korean brand "Kiturami" produces powerful heating equipment. The devices can compete with other famous brands. The model range is represented by mounted and floor-mounted units.

Wall-mounted boilers are attractive due to their compact size. They can be placed in any non-residential premises: kitchen, corridor. Floor-standing options require a separate room (boiler room). But you can count on high performance.

High power - from 13 to 470 kW - allows Kiturami equipment to heat residential and industrial premises.

Models differ in the type of combustion chamber. The closed type is connected to a coaxial pipe, which is led outside through a hole in the wall. The turbocharged burner takes air from the street, and the built-in fan forcibly removes the smoke outside.

The open chamber is connected to a stationary chimney. The flame in the burner is maintained by drawing air from the room.

Based on the number of circuits, Kiturami offers single- and double-circuit models. Devices with one circuit work exclusively to heat the coolant for heating. Double-circuit ones provide hot water supply (DHW) and heating.

Errors and malfunctions

What to do if there is an error on the display? Look at the instructions. Usually the manufacturer indicates the decoding of the values. Another thing is that it is not always clear to the user. We will tell you how to fix the problem.

Malfunctions of WORLD 5000 models

When the device is turned on and the CTR-5700 controller is started, the device does not respond. The lights don't come on and it doesn't start.

• Make sure there is voltage in the network. Plug any equipment into a power outlet.
• If it works, inspect the boiler; if not, then call an electrician.

The CTR-5700 external regulator is functioning, but the batteries are cold.

The coolant probably does not move well through the system:

• Open the fuel valve.
• Make sure the circulation pump is working properly.
• Adjust speed settings.

Diesel boilers Kiturami

With fuel prices constantly rising, diesel boilers are in high demand. The best-selling models are the Kiturami boilers of the TURBO series. TURBO 13R or 17R boilers are very economical to use, fuel consumption is 8 liters per day. It is better to place the fuel tank of these boilers nearby, and more powerful boilers (from 35 kW) are equipped with special pumps, which allows the tank to be installed in another room. Also, more powerful boilers have the option of replacing the diesel burner with a gas burner.
