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)
F2Air deficiency safety (lack of draft).The extractor/fan does not generate the necessary depression and the air pressure switch does not switch; the PCB locks with F2. Check the power supply and rotation of the fan, clean the turbine/venturi, and ensure the pressure switch closes (differential manometer/continuity).
F33Air flow fault.Insufficient performance or extractor blockage prevents achieving the flow/depression, and the air pressure switch remains open, displaying F33. Check that the fan is operating at the correct speed and that the pressure switch is switching (depression in venturi/continuity), as well as possible obstructions in the exhaust.

Verify the reference 0020124899 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?
