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)
02Air/flue fault: the flue circuit does not reach or confirm the required depression (air/SRC/fan/pressure switch).The air pressure switch does not switch (contact does not close/open) due to a fatigued diaphragm, obstructed silicone tubes, or lack of fan depression; check continuity at terminals with a multimeter during startup and use a manometer applied to the venturi to confirm that the pressure switch changes state.
F33Airflow fault: air pressure switch open/stuck (flue safety active).The air pressure switch contact remains open or stuck out of sequence due to a damaged diaphragm or insufficient pressure; check that the fan generates a vacuum, the condition of the tubes, and that the pressure switch operates by applying controlled vacuum and measuring continuity.
How do I know if this pressure switch is for my boiler?
Verify the reference 05169200 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Huba piece.
What is it used for?

Is the boiler not starting or showing a draught fault?

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
Check the tightness of the pressure pipes and the switching of the contact.
