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)
10Fan fault.The extractor fan motor does not start or is not recognized by the PCB (open winding, blockage, or wiring). Check that it receives 230 V~ at terminals, that it spins freely, and continuity/insulation; if it does not start, replace the fan.
02Air flow safety (draft/aspiration fault).The extractor does not generate the required flow/depression and the air pressure switch does not switch; there may be a blockage in the fan or flue circuit. Verify that the fan receives voltage and rotates, and check the closure of the pressure switch with the fan running and without obstructions in the exhaust.
