I have a Potterton Puma 80 boiler. Every time the boiler switches on from timer or fires up, the RCD trips out.
For a few weeks intermittently, only the hot water will work and CH not firing up. If I switch on the hot water, sometimes the boiler will stay fired up for the CH to come on.
My main problem now is that the boiler will not fire up at all with blowing the electrics (RCD)
Any help appreciated - could it be my pump causing this problem?
Thanks in advance
