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 electronics detect a flame when there shouldn't be one).The control board is one of the two documented causes of this code (the other is the detection electrode): if the board misinterprets the ionisation signal or its flame detection circuit fails, it triggers A02. Verification: first check the detection electrode and its wiring/connection to the board; if the electrode is correct and clean, the fault is with the board and the board should be replaced (Ref. 9158641).
