F05The air pressure transducer has not received a sufficient minimum value after 25 seconds.The air pressure switch/transducer does not close/deliver a signal to the PCB when the fan starts (damaged membrane/switch, blocked silicone tube, or wiring). Check the continuity of the pressure switch during start-up and the vacuum in the tube, and measure differential pressure/draught; inspect the chimney/fan.
How do I know if this pressure switch is for my boiler?
Verify the reference I39828420 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Huba Control piece.
What is it used for?

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.
