Suprima HE 60 Boiler - constant lockout

Hi there,

I have the above boiler that ignites every time, runs for around 10 minutes and then cuts out - fault code is "Air Proving Fault".  On last service had condensing trap, heat exchangers and flue checked so apparently not any of these issues.

Is it possible I may have a faulty air pressure switch?

Thanks

    The manual states " Check for blockages in the condensate system, the flue system and the heat exchangers"

    But probably new PCB required.
