Features of operation of Koreastar
The name of gas boilers "Koreastar" suggests that they are produced in Korea. But this is not so: they are produced in Europe, taking into account Russian conditions. Double-circuit models work stably with voltage drops in the network up to 15%.
Two heat exchangers provide heating for heating and hot water systems (DHW). Productivity reaches 13.6 liters per minute with a power of 32 kW. The heating capacity is designed for rooms with an area of 240 m².
Some models are equipped with bithermic radiators. They are designed according to the "pipe in pipe" type. At the same time, in one tube there is heating for hot water, in the other - for the circuit. Frost protection provided. The burner is equipped with a flame modulation system, so you can reduce the power at any time. Another feature of the burner is the pressurized type of operation, which makes the boiler quite noisy. You can read more about this in the review of Koreastar gas boilers.

The device and principle of operation of boilers
All GazLux gas boilers are double-circuit devices. They can operate at sufficiently low temperatures, withstanding pressure drops of up to 25 mbar. The latest modifications provide for the connection of heating to the “warm floor” structures.
The heating equipment GazLux "Economy" is controlled by rotary knobs, which set the required parameters for the temperature of hot water. They also set the air temperature. Models of this class are available with both open and closed combustion chambers.
Heat exchangers are available in two versions:
- for heating - finned tubular
, for hot water supply - lamellar; - bithermic coaxial
, made on the principle of "pipe in pipe".
GazLux "Standard" boilers are equipped with digitally controlled liquid-crystal monochrome displays, on which, in the event of a malfunction, corresponding messages are displayed. Displays allow you to adjust and program the necessary modes.
In GazLyuks "Premium" class, programming of heating boundaries during the day by specific segments is implemented. This is achieved with the help of color displays made on LEDs. In addition, such screens also monitor pressure in parallel.
The main causes and malfunctions of gas boilers
The typical thermal scheme for various gas-fired boilers is almost the same, the main elements of the thermal scheme include a boiler with a furnace and heaters for hot water, one boiler for single-circuit boilers for heating systems and two for double-circuit ones. A burner and chimneys connected to a chimney are located along the gas path.
If the boilers operate with forced circulation of flue gases, as in closed furnaces, then an additional exhaust fan or fan is installed to supply air to the furnace and create a gas-air mixture. The gas pipe system and pipelines of direct and return water are tied with the boiler using shut-off and control valves, in addition, safety and control automation devices are installed in the circuit. All these elements must work reliably and in concert with each other, otherwise, the boiler will issue an error code.
Other malfunctions
Error codes about the operation of the heater are not always displayed on its display. There may be cases when a breakdown has no indication.
If there are no symbols on the screen at all, then you should press the ON / OFF and RESET buttons. What to do if this method did not solve the problem? It is necessary to disconnect the device from the power supply. Then turn it on again.
Repeat this operation with the buttons one or two more times. If this does not help, then you will have to seek qualified help from specialists in the repair and maintenance of equipment.
Gas boilers GAZLUX (Gazklyuks) is a Russian development of heating equipment, which is manufactured in China. The model range is represented by three series: Economy, Standard and Premium. According to the principle device, the versions of the boilers are limited to double-circuit models with a bithermic heat exchanger, an open and a closed combustion chamber. The boilers are designed to work in closed heating systems with forced circulation of the coolant by a circulation pump and a pressure limit of 3 bar.
It is noteworthy that all boilers are equipped with a special magnetic device to prevent the formation of scale (the main problem that reduces the life of the “bithermic”).
The layout of GAZLUX heating equipment is contained in the full name of the model. For example, GAZLUX Economy B-18-C1 is a boiler of the Economy series with an open combustion chamber, with a rated power of 18 kW. Standard B-24-T1 is a boiler of the standard series with forced removal of combustion products (fan) and a power of 24 kW. The letter F may be present in the designation - this means that the boiler provides frost protection for the primary heat exchanger (preventing the circulation of cold air through the heat exchanger when the boiler is idle), as well as the ability to control draft when installed in multi-storey buildings with long chimneys.
In the Gazlux Economy series, control is carried out by rotary mechanical knobs, and the diagnostic system shows errors using LED indicators. The GAZLUX Standard series is already equipped with a liquid crystal display and push-button control, as well as the ability to program the boiler operating modes. The Premium series provides maximum opportunities - a color LCD display with error codes, boiler status display and programming.
Preventive advice
Modern gas boilers are very practical and thoughtful units, they have absorbed the best experience of the past decades, combined with the latest developments in the field of boiler materials, control and protection automation. They are made block, with the possibility of replacing worn parts and assemblies.
The units, which are operated according to the manufacturer's regime maps, are able to operate for decades without emergency shutdowns and replacement of components.
The weakest components of the Proterm boilers and the Buderus boiler:
- Heat exchanger - serves to transfer the heat of the exhaust gases through the developed pipe surface to the water of the heating circuit: heating and hot water. The duration of its operation largely depends on the quality of tap water and the presence of hardness salts and suspended impurities in it, as well as on the temperature regime in the network. At a temperature of more than 70 C, hardness salts are intensively deposited on the walls of pipes from the water side, gradually clogging the flow area. Low circulation causes overheating of water and pipe walls, on the surface of which fistulas form from excessive overheating. At the slightest suspicion of the presence of scale in the pipes, chemical cleaning of the inner surface of the heater is carried out according to the technology and reagents specified by the boiler manufacturer. In order to prevent scale formation, water purification filters are installed at the inlet to the boiler.
- circulation pumps. According to the new operating rules, the gas boiler unit operates on a closed heating system, which increases the efficiency of space heating and the possibility of automatic control of thermal conditions. Repair of pumps is usually caused by the presence of damage in the mechanical and electrical parts of the structure.
- The heating circuit temperature sensor outputs a parameter that is the main one in the automatic mode control system, in connection with which the boiler is turned on / off, its malfunction may be in the contact group or caused by a break in the communication line.
- Gas burner - the main device of the boiler, which burns fuel to produce thermal energy. The repair of this device consists in cleaning the nozzles.
- An expansion tank is a unit that compensates for the excess pressure of the medium that occurs during the heating process. The repair is carried out by replacing the elastic membranes.
Most of the parts and assemblies for repairing the boiler are in the distribution network, they are also easy to find on the Internet, but if the boiler is under warranty, it is recommended to purchase them through service centers, which will guarantee not only high-quality repairs, but also its durability.
Malfunctions of the GAZLUX Economy gas boiler
The device of any modern gas boiler must have a control unit - an electronic board that is responsible for the process of starting and stopping the boiler and fully controls the process of its operation. Also, the second important function of the board is to protect the device in case of emergency situations and malfunctions.
Such situations may include:
Problems with the removal of combustion products
Gas burner damping
Insufficient coolant pressure in the hydraulic circuit of the boiler
Boiler temperature too high (overheating)
The listed faults are critical and the operation of the boiler will be immediately blocked for safety reasons.Failures can occur accidentally, for reasons independent of the equipment, for example, during interruptions in the gas line or freezing of the chimney.
Depending on the configuration of the equipment, faults can be displayed either as a combination of lit LEDs or as a digital code on the display.
GAZLUX Economy and Standard errors
To display errors on this boiler model, a special group of indicators (position 5) is provided. During normal operation of the boiler, they display the current power level.
E1 error. The lower indicator flashes red 1 time per second, the first power LED is lit on top.
The fault is caused by a flue gas temperature sensor (for an atmospheric boiler) or a differential pressure sensor for a turbocharged boiler. This malfunction may be due to the difficulty (or impossibility) of removing combustion products. Need to check:
inlet and outlet pipelines - they must be free (visual inspection);
the fan must run smoothly and without interruption;
the pipes leading to the differential pressure transmitter must not be deformed or clogged.
Error E2. The lower indicator lights up red, the second power LED lights up from the top. Breakage of the temperature sensor of the heating system (supply pipeline).
NTC sensors are tested by measuring resistance. In most cases, at room temperature, the resistance is about 10 kΩ and decreases with increasing temperature. If there are strong deviations during the check, then most likely the sensor is faulty and needs to be replaced.
Error E3. The lower indicator lights up red, the third power LED lights up from the top.
The same as for the previous error, but for the temperature sensor of the DHW system.
Error E4. The lower indicator lights up red, the fourth power LED lights up from the top. Signal from the safety thermostat installed downstream from the primary heat exchanger. So, for some reason, the temperature of the coolant exceeded 92 degrees. In most cases, overheating is the result of poor circulation of the coolant. Poor circulation can be caused by:
malfunction of the circulation pump (difficult or no movement of the coolant)
poor patency in the heat exchanger (scale or blockage)
air lock in the heating system
Error E6. The lower indicator is lit red, the first and fifth power LEDs are lit on top.
The control unit does not detect the presence of a flame on the burner. To prevent explosive situations, the boiler automation constantly monitors the presence of a flame through a special electrode (also called an ionization electrode). When a combustion flame is present, the board registers a small current through the electrode, if this does not happen, the boiler turns off by mistake. Why this might happen:
there is no normal gas supply (the reasons may be different: low pressure in the gas line, clogging of the burner cavities, contamination of gas filters, malfunction of the gas valve)
the ignition system is faulty (circuit breakage on the control board)
malfunction of the ionization electrode (contamination, short circuit to the case)
Error E7 (Eb). The lower indicator is lit red, the second and fifth power LEDs are lit on top.
Similar to the previous error.
The lower indicator lights red, the upper power LEDs flash in sequence. The electronic board registers combustion after closing the gas valve. This means that either the gas valve does not fulfill its function (the gas does not completely shut off - there is a leak), or the boiler electronic board is faulty.
EP error. The lower indicators flash (green and red). Low pressure in the heating system (no circulation).
In boilers of different years of manufacture, different devices were used to control the coolant. In boilers up to 09/2007 of the economy and standard series, reed sensors were used (closing of the sensor contacts when the coolant circulates at a speed of more than 4 liters per minute).Since 09/2007, differential pressure sensors have been used. The boilers of the Premium series use pressure sensors to measure its value quantitatively and display it. The resulting malfunction indicates that either there is a circulation problem (the pump is faulty, there is an air lock), or the pressure in the heating system is not enough (recharge is necessary).
The lower green indicator blinks (often - 4 times), the upper ones do not light up.
Frost protection function of the boiler is active
The lower green indicator flashes (suddenly once every three seconds), the upper ones do not light up.
No request to turn on the burner, the pump overrun function is active.
Errors are reset either by turning the boiler on and off, or by pressing the Reset button (wrench). Exclusion of protective devices from the control circuit (for example, forced closing of sensors) is prohibited. If, after resetting the error, the malfunction occurs again, then it is necessary to take measures to eliminate it for further normal operation of the boiler.
Beret boiler errors
The main errors of the beret boilers are displayed in an alphanumeric or numeric code. These include the following:
- A01, signals problems in the ignition system after 5 consecutive attempts to ignite the boiler;
- A02, the “bell” symbol will appear on the display, which indicates blocking by the limit thermostat;
- A03, the flue gas thermostat is activated;
- A04, the ignition valve relay has tripped;
- A07, safety relay (possible problems in the electronic board);
- 10, indicates that there is no flame on the burner.
All beret boiler error codes displayed are also described in the instructions.
Baxi boiler errors
Baxi boiler errors displayed on the display cover the entire range of possible malfunctions. Most frequently displayed:
- E 01, triggering of the flame control sensor itself or its breakdown;
- E 04, short-term loss of flame on the burner;
- E 035, the presence of a flame before opening the gas cock or the remains of a flame after turning off the burner;
- E 10, violation of the circulation of the coolant, pressure reduction in the heating system;
- E 96 - e 99, Baxi boiler errors associated with malfunctions in the electronic board.
Navien boiler errors
Navien boiler error codes help determine the troubleshooting algorithm. For example:
- 02E, violation of normal circulation in the heating system;
- 03E, no flame signal;
- 12E, the flame went out;
- 14E, no normal gas supply pressure gas.
Vaillant boiler errors
The most likely situations of possible malfunctions are displayed on the display in the form of error codes for Vaillant boilers:
- F22, insufficient pressure in heating systems;
- F24, rapid temperature increase in the boiler;
- F26, problems with gas fittings;
- F27, flame simulation;
- F28, problems in the ignition system.
Ferolli boiler errors
The Ferolli boiler, like other modern boilers, has a self-diagnosis function that displays errors on the display:
- A01, no flame or ignition problem;
- A02, false flame, board failure;
- A03, overheating of the Ferolli boiler, careful diagnosis is required;
- F04, thermostat overheating or malfunction. Sometimes the problem is solved by rebooting the boiler;
- F05, no fan connected in the system. Disconnect and reconnect it.
Boiler errors Proterm
Errors F00, F01, F10, F11 at the Proterm boiler indicate a failure of the temperature sensor. It is not always necessary to replace it, sometimes a more thorough diagnosis and flushing of the boiler helps. F20 indicates overheating of the boiler, long-term operation without inspection is not desirable. F24 the boiler is clogged.
Gaslux boiler errors
- Error E1, malfunction of the boiler fan. Either it is out of order, or there is a problem with smoke removal;
- Error E2, the water temperature sensor does not respond to signals, it should be replaced;
- Error E4, overheating of the gas boiler, flushing of the system is required.
Rinay boiler errors
Main mistakes:
- 11, No flame or ignition from control board;
- 14, the temperature sensor overheats, it needs to be replaced;
- 16, the temperature of the boiler coolant rises above the set temperature.
Wiesmann boiler errors
Main mistakes: Previously, Viessmann boilers were considered very reliable and there were no instructions for them, but over time, any equipment breaks down, so here are their mistakes:
- 06, the coolant pressure level is insufficient in the system;
- 0C, low voltage in the network;
- F2, burner failure.
All of the above does not reflect all the possibilities of modern electronics installed in modern gas equipment. A complete list of error codes for gas boilers gazeko, immergaz and others is always indicated in the attached instructions. There may be slight differences for some models of the same brand, for example, errors in chao beret boilers show specific causes of malfunctions only for this model.
What to do in a situation where there is the slightest suspicion of a violation of the normal functioning of gas equipment? Contact the master. Even after reading detailed instructions on how to fix the problem that has arisen and without practical experience, it will hardly be possible to restore the boilers to working capacity. It should be remembered that gas boilers are considered objects of increased danger and any unprofessional actions can lead not only to a complete breakdown of the equipment, but to more disastrous consequences.

Documentation
Error codes and malfunctions
In case of any malfunction in the operation of the boiler, the user must first look at the instructions. Most errors are listed by the manufacturer. It's just not always clear how to fix them. We recommend restarting the equipment immediately:
- Press the restart key;
- Wait for the boiler to restart;
- Make sure the characters have disappeared from the screen.
If nothing has changed, start looking for a breakdown. The table below shows solutions for different problems.
| Fault codes | What do they mean | How to fix it yourself |
| A01 | The system does not report the presence of a flame. |
|
| A02 | A flame was reported, although there was no ignition. |
|
| A03 | Overheating technology. Boiler operation is blocked. The temperature is over 90 degrees. |
The thermostat has tripped. First of all check it for serviceability. Drain excess air from the system using Mayevsky taps.
- circulation pump. If it is faulty, replace or adjust the settings. Clean the impeller blades from blockage;
- If the error is displayed again, repair the electronic module.
A08/F10
The heating circuit temperature sensor is out of order.
Checking the sensor, its connections and contacts. In the event of a short circuit (short circuit) or open circuit, a new element is installed.
F05
Incorrect operation of the gas removal system.
View:
- Air relay connection;
- Air diaphragm for sticking;
- Fan performance.
- Shafts or chimney pipes. It is often clogged with soot, soot. In strong winds, leaves and debris can get inside. For a complete cleaning, it is better to contact the utilities.
F11
Hot water NTC temperature sensor failed.
I got error F11, what to do:
- Check the sensor for short circuit and open circuit.
- Ring the contacts with a multimeter. Normally, the indicators are 10 kOhm.
- Reconnect item. In case of breakage, connect a new element.
If ignition does not occur when DHW is turned on, inspect the three-way valve that switches heating between circuits.
F37
Low pressure in the circuit (less than 80 kPa).
Make sure the pressure sensor, its wiring is in good condition. Inspect all connections and assemblies for leaks. Any damage is sealed. Turn on water supply to the system.
F41
The movement of the coolant is disturbed. The heat exchanger is overheating.
How to fix the situation:
- Inspect the heat exchanger for scale. Clean the tubes of deposits with reagents or citric acid. A layer of scale on the radiator interferes with water circulation, worsens heating, from which the unit overheats;
- Bleed air from the pump. Set the appropriate mode. Install a new pump if it breaks.
F50
The electronic board is not working.
Checking grounding, boards for breakdown. It is better to entrust repair and replacement of the control module to a specialist.
Unfortunately, not all malfunctions of Koreastar heating equipment are displayed as a code on the display. Users complain that the devices are sensitive to voltage drops, which is why the control board often suffers. And this is despite the manufacturer's assurances of stable operation at any jumps. Therefore, when choosing Koreastar, it is worth additionally connecting a stabilizer.
Experts recommend annual preventive maintenance of breakdowns. Clean the unit from dirt, scale, conduct a technical inspection.
