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.61Fuel control valve error.The control/reading stage of the PCB to the gas valve fails (driver/relay/triac or return reading), blocking the boiler; check the continuity of the harness and measure the control/return signal on the board before replacing the PCB.
F.63Fault: EEPROM.Corruption/defect of the EEPROM memory integrated in the PCB; if sensors/wiring are correct and the fault reappears after reset, verification is done by replacing/programming the PCB.
F.64Fault, electronics/temperature sensor.The measurement electronics (ADC/reference on PCB) interpret incorrect NTC values; after ruling out NTC/harness, check 5 V/ground and reading stages on the PCB or confirm by substitution.
F.65Electronic temperature fault.Overheating measured on the PCB itself (internal sensor or power area); if it persists with proper ventilation and no external heat sources, the PCB is damaged—verify with thermography/sensor and replace.
F.70Invalid device identification (DSN: "Device Specific Number").Mismatch/incorrect coding after changing the display and/or PCB or using an incorrect board; verify/adjust DSN from the service menu or with SAT equipment; if it does not accept coding, the PCB is not the correct one.
How do I know if this PCB is for my boiler?
Verify the reference 0020027631 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.
