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)
6Flame detection faultThe flame detection/management stage of the PCB (control board 074278) may fail and the boiler does not recognise ionisation. Verify by measuring the ionisation current and, after ruling out cable/spark plug and ignition module, replace the control board to confirm.
29Gas valve relay fault of the burnerThe control relay of the gas valve on the control board (PCB) may remain open/stuck, and the self-diagnosis detects it. Verify by requesting ignition and measuring 24 Vdc towards the valve; if the relay does not switch, replace the control board.
30Gas valve relay fault of the burnerSame diagnosis as on the 29th: fault of the gas valve relay integrated in the control board (PCB). Check for the presence/switching of 24 Vdc to the valve during demand; if it fails, replace the control board.
How do I know if this PCB is for my boiler?
Verify the reference 074278 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is an Intergas 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.
