I have a potterton gold 24he combi
The boiler keeps displaying e133 (gas fault) and it takes about 20 attempts at resetting it before it fires up some times more, I ordered a new pcb board and fitted this but exactly the same problem now i have run out of ideas except to thinking maybe the gas valve is faulty.
Any sensible ideas/solutions will be appreciated

I am not sure if this will help but we had the same problem and my husband said it was something to do with the timer i.e. there was a lose connection to one of the wires when he took the front off. He could not fix it so we are going to buy a new timer.
It's worth looking at yours though as you never know it may be able to be repaired - good luck.
