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)
E05Flue pressure switch anomaly.The air pressure switch does not switch (damaged diaphragm/contacts, blocked hoses or venturi inlets); check micro continuity at start-up and the depression in the venturi with a manometer (in Pigma 24 FF ≥70 Pa).
6 07Pressure switch ON Fan OFF (flue pressure switch closed with fan stopped).The pressure switch remains stuck/closed due to internal fault or moisture in the tubes; check that it remains closed without depression (continuity test) and ensure that the hoses do not have siphon/condensate.
6 08Pressure switch OFF Fan ON (flue pressure switch open with fan running).The pressure switch does not close when draft is generated (fatigued diaphragm or blocked connections/hoses); check that it closes with the fan running by measuring continuity and pressure drop in the venturi.
6 P1Flue Pressure Delay (late closure of the flue pressure switch).The pressure switch takes time to switch to ON due to slow response or lack of initial depression; measure the micro-switching times when the fan starts and clean the pressure switch connections/hoses.
6 P2Flue Pressure Opening (unexpected opening of the flue pressure switch).The pressure switch opens during service due to membrane instability or momentary loss of depression; monitor micro continuity with the fan at speed and check tubes and connection to the venturi.
How do I know if this pressure switch is for my boiler?
Verify the reference 65111458 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?
The pressure switch controls the pressure/draught (of air in sealed systems) or water to authorize operation.
Is the boiler not starting or showing a draught fault?
If the fan spins but does not ignite, check the pressure tubes (loose/blocked), the diaphragm, and the fan.
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.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
