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

check you havent got reversed polarity ie 240 volts on the neutral
then i would replace the electrode and lead if thats ok

was this the same problem it had before you replaced the pcb

This problem has only started in the past 2 week, but the boiler has been going off for the past 6 month hence changing the PCB

is the green light continally flashing (quickly) once burner has ignited?

If so, the electrode / lead will need changing.

Filing the electrode (ie cleaning it up) usually works.

did you change the whole kit 5111603 or just fit an illegal recon pcb

Have just been told it could be the gas valve?Very costly apparently?

No Gaz I bought a new PCB for £120

if you have paid under 200 notes for a potty pcb (not that they overcharge) then you have bought the piece of trash that potty swore blind had no faults with it.

Replace it (for the equally poor) upgrade and rewire the boiler - just like everyone else does with their boilers nowadays.

Actually they dont. Its a potty priveledge. I can only assume it gives their cutomers a sense of adventure

surprised you could get one as they stopped being made about 2 years ago

also soggy in what way is the new upgrade poor ive fitted 100s and had maybe 1 or 2 faults

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 ??????
