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)
F61Fault in the main PCB.The PCB can fail in the control circuit (e.g., output to gas valve/eBUS), triggering the self-diagnosis. Check 230 V and 5/12 V on the PCB, connectors, and DSN code; if everything is correct and the issue persists, replace the PCB.
F63Memory fault in the main PCB.Memory corruption/defect in the PCB. Try a reset and check DSN; if not resolved, verification points to replacing the board.
F64Fault in main PCB (rapid fluctuation of flow/return sensor).The ADC of the PCB interprets impossible variations of the NTC; if wiring and sensors are fine, the origin is in the electronics of the board. Check connections and, if it persists, replace the PCB.
F65Fault in main PCB (excessive electronic temperature).Overheating of the PCB electronics (power supply). Check ventilation/dissipation and connections; if there are no external causes, the PCB is damaged and must be replaced.
F67Fault in main PCB (flame signal on PCB).The flame detection circuit on the PCB interprets an anomalous signal; if the electrode, ground, and wiring are correct, the fault lies in the control board. Confirm by measuring and, if it persists, replace the PCB.
