6 engineer visits and still boiler not fixed!

This thread made me laugh. WB have always been rubbish boilers & yours was past its best about 10 minutes after it was fitted.

As for the 6 engineers(use the term loosely!) c'mon!!

I read 8 but anyway.....the 350 is an awesome boiler. The orignal honeywell air pressure switches were replaced by a huba. The originals were fitted horizontally but if you fit the replacements the same way the fan doesnt always lift it to switch to NO. Unfortunately if you fit the replacement dead vertical it tends to stick in the NO position after a demand so it just needs to be slightly tilted in order for it to fall back to NC. I doubt it matters if you tap near the pcb or near the flue to release the air pressure switch after a demand.
