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)
A02Flame signal present with burner off.The flame detection circuit on the PCB can falsify the ionisation signal; after checking the electrode, ground, and wiring, if everything is correct, check/replace the PCB.
A61ABM03 control board anomaly (internal error).Internal fault of the ABM03 module integrated in the PCB; check the grounding and power supply, and if it persists, replace the control board/PCB.
A63ABM03 control board anomaly (internal error).Internal fault of the ABM03 module in the PCB; check earth/power supply and, if the error persists, replace the control board/PCB.
F64ABM03 control board anomaly (internal error).Internal error of the ABM03 controller on the PCB; check grounding/network noise and, if it persists, replace the PCB.
A65ABM03 control board anomaly (internal error).Internal fault of the ABM03 module in the PCB; confirm grounding/good power supply and replace the control board/PCB if not corrected.
F66ABM03 control board anomaly (internal error).Internal fault of the ABM03 control board integrated in the PCB; if it persists after checking the ground and power supply, replace the PCB.
A23Anomaly in the parameters of the control board.PCB parameters misconfigured/corrupted; check and reprogram from service menu/tool, and if it doesn't save, replace the PCB.
A24Anomaly in the parameters of the control board.Configuration/firmware of the PCB with incorrect parameters; check/load correct values and, if it fails, replace the PCB.
F20Anomaly in the parameters of the control board.Parameters of the PCB altered; check with service tool and reprogram or replace PCB if it does not maintain configuration.
F21Anomaly in the parameters of the control board.Parameterisation error in the PCB; reconfigure/load default settings and, if it reappears, defective PCB.
A26Anomaly in the parameters of the control board.Parameters of the PCB incorrectly loaded; check with the technical menu and, if not corrected, replace the PCB.
F40Anomaly in the parameters of the control board.PCB configuration values out of range/corrupt; reprogram and, if it persists, replace the PCB.
F47Anomaly in the parameters of the control board.Incorrect internal parameters of the PCB; verify/load factory values and, if it persists, replace the PCB.
How do I know if this PCB is for my boiler?
Verify the reference 39845844 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.
