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)
F4Operation of the air pressure switch.The air pressure switch remains closed when it should open (stuck contact or tubes/venturi improperly connected/blocked). Check with a multimeter that it opens when the fan stops and inspect pressure tubes and air/smoke ducts.
F5Operation of the air pressure switch.The pressure switch does not close within the time (~55 s) after activating the fan due to lack of depression/draught or a defective pressure switch. Check closure with a multimeter when starting the fan and inspect the venturi, pressure tubes, and possible obstruction in air/smoke.
F6Operation of the air pressure switch.The pressure switch contact remains closed after several start-up attempts, indicating a stuck APS or reversed connection. Measure opening/closing with a multimeter and check the correct connection of the tubes to the pressure switch and the operation of the fan.
