Polykraft Gas Boiler Error Codes Error 01 It means that the ignition is blocked. Fault notification comes from the flame control sensor. Such an element detects the presence of a flame and suspends the operating cycle of the Polycraft boiler during insufficient combustion of the main burner or in case of gas supply problems. The termination of work occurs at the end of three unsuccessful starts. To get it working, you need to press and hold the Reset key.
Polykraft Boiler Error Code Solutions
Gas valve failure – The operation of the gas valve is controlled by an electronic board. Diagnostics of this component is carried out by measuring voltage and resistance. If the readings do not correspond to the standard characteristics, it is required to replace the valve. No gas flow to the unit – A valve is placed in the gas distribution system, which limits the flow of gas fuel. That’s why, failure to start the device may occur due to a blocked valve. Poor contact or no signal from the flame ionization sensor. Faulty electronic board – When the ignition is done normally, but the boiler goes out abruptly, it seems that the electronics cannot see the flame. In this case, it is necessary to check it.
Polykraft Boiler Error Code 02
The heat exchanger of the Polykraft boiler is overheated. The device is blocked. The overheating thermostat is activated – The overheating thermostat, as well as the temperature sensor, are mainly located on the outlet pipe of the primary heat exchanger. The functional task of the thermostat is to protect the device from elevated temperatures. An emergency situation may occur due to problems in the thermostat, temperature sensor, as well as in case of difficulty in the operation of the main circulation circuit.
Damaged temperature sensor – The control board receives an incorrect signal or the contact between the sensor and the control board is broken. The overheating thermostat is out of order – If the component is operational, but a real overheating of the coolant is detected, then it seems that there is a violation of the circulation of the coolant of the heating circuit. Clogged main heat exchanger or main circuit filter element (lack of circulation causes high fluid heating). Malfunction of the circulation pump or there is a blockage from the air in the heating system.

Means that the pressure inside the system is not enough. Probable causes influencing the formation of this malfunction: reduced water pressure in the heating circuit. The contact between the pressure sensor and the electronic board is broken. Malfunction of the minimum pressure switch. Initially, you should look at the pressure gauge values. In many cases, the problem can be fixed with a make-up valve that is installed to fill the system with coolant. When the accident reappears, then most likely there is a fluid leak. A hydraulic pump, primary heat exchanger, safety valve, damaged gaskets, make-up valve and other components can leak. Leakage can be detected by inspecting hydraulic components.
Polykraft Boiler Error Code 03
Insufficient traction. For the correct and safe operation of the Polykraft gas boiler, it is recommended to create a draft to remove exhaust gases so that they do not enter the room. The exhaust of gases is controlled by electronics, and if certain problems appear, the draft sensor turns on and the unit stops working. Probable causes affecting the lack of draft: small diameter of the flue duct, incorrect design, pollution, ice on the inner wall. Narrowing the diameter of the outlet channel leads to weak draft. Exceeding the permitted length of flue pipes Read the installation manual for the boiler carefully and comply with the relevant requirements. A sufficiently long horizontal section of the flue pipe can lead to a loss of the necessary draft. Malfunction of a pneumatic relay-traction sensor – If a vacuum occurs in the inlet tube, you can catch a characteristic click.
There is no contact between the pressure switch and the control board, there is condensate, as well as incorrect connection of the tubes to the pneumatic relay. Fan stopped – The fan impeller is clogged. The lack of sufficient lubrication of the fan shaft, therefore, it does not generate the required speed. Lost contact between the electronic board and the fan. hence it does not generate the necessary revolutions. Lost contact between the electronic board and the fan. hence it does not generate the necessary revolutions. Lost contact between the electronic board and the fan.
Polykraft Boiler Error Code 06
Failure to determine the temperature of the DHW sensor. This code means that the DHW circuit temperature sensor is damaged or the recommended temperature has greatly increased. The main factors contributing to the appearance of this problem: the hot water temperature sensor is not operational. There is no contact between the electronic board and the DHW temperature sensor. Electronic board defective. When the DHW temperature sensor is in good condition and correctly connected to the electronic board, although the device shows an error, then, apparently, the control board is not operational.
Polykraft Boiler Error Code 35
Ignition problem. This circumstance is issued if there is no ignition or if there is a burner flameout. Diagnosis should be made of the connections between the ignition device and the flame electrode, and also between the control board and the gas valve. One of the reasons for the blow-off of the burner flame may be weak draft.
Polykraft Boiler Error Code 05
The heating circuit temperature sensor is not working correctly. This code indicates that the heating circuit temperature sensor is damaged or the temperature required for operation is too high. Damage to the heating circuit temperature sensor circuit – This malfunction occurs if the temperature sensor is not communicating with the electronics board, or the temperature is below the nominal temperature. 5 seconds after the failure is detected, the Polycraft boiler will resume correct operation if the failure occurred spontaneously. It is required to make sure that there is no moisture on the temperature sensor connector and the electronic board connector.
If there is no moisture, it is required to change the temperature sensor. The appearance of a short circuit in the temperature sensor of the heating circuit – This situation occurs after a short circuit in the temperature sensor circuit or the temperature value of the liquid is higher than the nominal value. First of all, it is recommended to measure the resistance of the temperature sensor. If the resistance parameters differ from the nominal ones, the sensor should be replaced. If the installation of a working sensor does not work, change the controller.
