Did the Koreastar boiler display errors on the display? This means that the self-diagnosis system “detected” a malfunction. All modern heating equipment is equipped with automation - sensors that monitor the operation of each node. Sometimes the user does not even need to contact the service center. It is enough to determine the value of the code and find the problem.
Operation Features of Koreastar
The name of the Koreastar gas boilers suggests that they are produced in Korea. But this is not so: they are produced in Europe taking into account Russian conditions. Dual-circuit models work stably with voltage drops of up to 15%.
Two heat exchangers provide heating for heating and hot water supply (DHW). Productivity reaches 13.6 liters per minute with a power of 32 kW. Heating facilities are designed for rooms of 240 m².
Some models are equipped with bithermic radiators. They are designed like a pipe in pipe. At the same time, heating takes place in one pipe for domestic hot water and in the other for the circuit. Provides frost protection. The burner is equipped with a flame modulation system, so you can reduce power at any time. Another feature of the burner is a supercharged type of work, so the boiler works quite noisily. You can read more about this in the review of gas boilers "Koreastar".
Error and Fault Codes
In case of any malfunction 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 eliminate them. Immediately recommend restarting the technique:
- Press the restart key;
- Wait for the boiler to resume operation;
- Make sure the characters disappear from the screen.
If nothing has changed, start looking for damage. The table below shows solutions for various problems.
Malfunction codes | What do they mean | How to fix it yourself |
A01 | The system does not report a flame. |
|
A02 | A flame was reported, although there was no ignition. |
|
A03 | Overheating equipment. The operation of the boiler is blocked. The temperature exceeds 90 degrees. | The thermostat has tripped. First of all, check it for serviceability. Blow excess air out of the system using Mayevsky taps. Diagnose:
|
A08 / F10 | The temperature sensor of the heating circuit is out of order. | Checking the sensor, its connections and contacts. In case of short circuit (short circuit) or open circuit, a new element is installed. |
F05 | Incorrect operation of the gas removal system. | Inspect:
|
F11 | The NTC temperature sensor for hot water is out of order. | Error F11 was highlighted, what to do:
If ignition does not occur when the DHW is turned on, inspect the three-way valve, which switches the heating between the circuits. |
F37 | Low pressure in the circuit (less than 80 kPa). | Make sure that the pressure sensor and its wiring are working. Inspect all connections and components for leaks. Any damage is sealed. Turn on the water system. |
F41 | The movement of the coolant is disturbed. The heat exchanger is overheating. | How to fix the situation:
|
F50 | The electronic board does not work. | Checking grounding, boards for breakdown. Repair and replacement of the control module is best left to a specialist. |
Unfortunately, not all Koreastar heating equipment malfunctions are displayed by a code on the display. Users complain that the devices are sensitive to voltage surges, which often causes the control board to suffer. And this is despite the manufacturer's assurance of stable operation at any jumps. Therefore, when choosing “Koreastar”, it is necessary to additionally connect a stabilizer.
Experts recommend annual breakdown prevention. To clear the unit of pollution, a scum, to carry out technical inspection.
