My boiler [potterton puma 80] is not working. The pilot light is on but will not fire up,no mains light on. I have already changed the fuse..plz help..freezin'!!!
common fault with this bouler needs a new modulation PCB.

Had the fuse blown? is the pump running? switch it on and try to isolate each part i.e. pump Divert valves etc to see if one of these is the cause of the fuse blowing if not sounds like you will need to replace the control module.
