the hot water on my ferolli hawk 2 only works when i disconnect the white air pipe on top af the air pressure switch . i have replaced this however it has made no difference. is it still safe to use like this?

In a word NO, the purpose of the air pressure switch is to prove that any fumes will be pumped out of the boiler safely if it isnt proving that the poisonous fumes are being pumped out safely then you risk being killed via carbon monoxide poisioning
