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)
F12Main PCB circuit fault (PCB ↔ interface connection).The main PCB does not establish/receive communication with the control board (internal fault of the PCB or its auxiliary voltages). Check 230 V input and 5/12 V on the board, continuity of the interface harness–PCB, and if the interface and wiring are OK, replace the board.
F13Main printed circuit board fault.Internal defect of the PCB (cold solder joints, relays/controller, power supply) causing loss of management/communication. Check voltages on the PCB, perform a visual inspection, and rule out the interface and harness; if the issue persists, replace the PCB.
F20Software incompatibility (interface ↔ PCB/product code).After changing the PCB or display with an incompatible version/code, the PCB locks due to software mismatch. Verify variants/product code and versions on the label/technical menu, reconfigure or install a compatible PCB.
How do I know if this PCB is for my boiler?
Verify the reference 0310144400E5 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.
