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.20Safety temperature limiter disconnection.The PCB may incorrectly interpret/manage the input from the limiter (thermal fuse) and trigger the safety. Check by bridging the limiter according to the manual and, if the wiring/sensor are OK, measure the input on the board or replace the PCB.
F.27Safety lockout flame simulation.Moisture/damage in the PCB electronics can simulate an ionization signal. Check by drying, checking continuity/voltages of the board and the electrode; if it persists, replace the PCB.
F.37Fan speed difference fault.The PCB powers and reads the fan (power/PWM and tach signal); a driver fault or reading on the board triggers the code. Check 12 V/PWM and speed signal at the board connectors (e.g., X30/X91) and, if the fan/harness are fine, replace the PCB.
F.57Measurement program fault.Internal electronic error; if it persists after a reset, the PCB is defective. Check supply voltages and continuity; replace the PCB if it does not start.
F.63EEPROM fault.Corrupted/damaged EEPROM memory of the PCB. Check reset and power supply stability; if the fault persists, replace the PCB.
F.166Communication fault.Fault in the communication electronics of the PCB (e.g., bus/display). After ruling out interruptions in the harness, levels, and connectors, replace the PCB.
F.168Fault in the water escape sensor.The analogue input on the PCB may fail and incorrectly detect a leak. If the sensor/wiring are OK or bridging the sensor makes it disappear, replace the PCB.
F.171Fault: fan.The PCB controls the power/control of the fan; a faulty driver/power supply on the board causes the code. Check 12 V and control signal from the PCB before replacing it.
F.197Supervision protection fault.Fault in the control/monitoring electronics on the PCB. If the appliance does not start after a reset, replace the board according to the manual.
How do I know if this PCB is for my boiler?
Verify the reference 0020251359 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.
