Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
F.61Gas valve control error.The output/driver stage of the PCB (252945) does not energise the valve; if coils and wiring are OK, the electronics are the cause. Check for 230 V at the valve during start-up, and if no voltage is present with correct power supply, replace the PCB.
F.62Gas valve disconnection delay.If the gas valve and flame signal are correct, the fault is usually in the electronics that de-energise the valve. Check for tightness/ionisation; if everything is correct, check the output/relay-triac on the PCB and replace it if the issue persists.
F.63EEPROM error (memory) – defective electronics.The EEPROM of the PCB (252945) is damaged/not readable; the equipment locks up. Check voltages 5 V/24 V and, if wiring/sensors are fine, the documented solution is to replace the PCB.
F.64Electronic system/NTC fault.The measurement circuit on the PCB detects a short circuit/implausible value or the electronics are defective. Measure the NTCs and wiring; if they are correct and the fault persists, the cause is the PCB.
F.65Electronics temperature too high / defective electronics.The PCB overheats or its internal sensor fails, causing a lockout. Check ventilation/temperature; if it reoccurs without external overheating, replace the PCB.
F.70Invalid appliance code (DSN).Coding mismatch between display and PCB or missing/incorrect coding resistor on the PCB (typical after changing the board without parameterization). Verify and reprogram DSN/coding; if it does not recognize the resistor, replace the PCB.
How do I know if this PCB is for my boiler?
Verify the reference 252945 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.
What is it used for?
The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.
Is the boiler not igniting, locking out, or is the control board unresponsive?
After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
