Hi, im not getting an ignition on the above boiler, had a plumber out who's first diagnosis was that it might be the pcb, as all the other workings seem to check out ok. He has not come back to sort the problem and Ive been without hot water for a month. Since ive spoken to the landlord, ive proposed that I order a new pcb as that was the plumbers original diagnosis, but he never tested the pcb and the landlord has been informed by the plumber that he now thinks its the pressure switch? Ive taken the board out since, and am half tempted to order a new one, but do not want to waste a £100 on it if the board is fine. Is there a way to test the pressure switch myself, ive some knowledge in plumbing but only
know a little when it comes to boilers.
pressure is at 2bar all the workings of pcb seem to function, timer, and variable temparature switch activates as normal all valves have been checked for blockages and pump is fine, all fuses are ok
So any ideas on how to check if its the pressure switch?
Board has been put back and is still functional but still not igniting the gas.
thanks in advance
