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)
F.32Frost protection function of the fan active: fan revolutions exceed tolerance values.The fan/extractor is blocked, without power or without Hall signal, and the PCB detects rpm out of range. Check the connector and 230 V to the fan, Hall/tachometer signal, and ensure it rotates freely during pre-ventilation.
F.33Pressure losses in the air intake/exhaust gas system are too large.The fan does not overcome the pressure loss of the air-flue circuit (motor/blades fatigued) and the pressure switch does not confirm. Check the fan's rpm/consumption, ensure it is not obstructed, and measure differential pressure/pressure switch during pre-ventilation.
