Could the problem be with the motorised valve, I took the cover up and pressed in the relay button with a small screwdriver and the boiler lit and stayed lit for 10 mins, when I removed the screwdriver the boiler went back out ??????
Could anyone offer any advise on my boiler please, I have just fitted a new PCB to the boiler because I thought that was were the problem was but no....
The problem is the fan starts OK, then the ignition lights the flame, but then cuts out after about 5 secs... PLEASE HELP
