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.63Fault: EEPROMThe EEPROM memory of the PCB is damaged or unreadable. Check the power supply voltages of the PCB and attempt a reset; if F.63 persists after ruling out power supply and parameterisation, replace the PCB.
F.64Fault: PCB / sensor / analog to digital transformerDefect in the A/D converter or sensor reading stage in the PCB. Rule out NTCs and wiring (resistance/continuity measurement); if they are correct and F.64 persists, the cause is the PCB.
F.65Error: electronics temperature too highThe PCB electronics detect overheating (sensor/measurement on PCB). Check ventilation and thermal conditions; if the F.65 reappears when cold after ruling out external causes, the PCB is defective.
F.67Incorrect value returned by ASIC (flame signal)Fault in the detection/ASIC stage of the board that evaluates ionisation. Check electrode, cable, and grounding; if everything is correct and the signal is still not plausible, the fault is in the PCB.
F.70Invalid product code (DSN)Main PCB and interface mounted without recoding the DSN/power class resistor or incompatible. Check and recode in service menu (.d.93); if it does not accept coding or reappears, replace/parameterize the correct PCB.
F.61Error: gas valve controlFault in the driver/output of the control board that governs the coils of the gas valve. Rule out shorts in the harness and coils; if they are correct and the manual considers 'defective electronics', the PCB is the cause.
How do I know if this PCB is for my boiler?
Verify the reference 0020039204 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.
