Any ideas would be appreciated.
I have isolated the pump, fan and gas valve. Initially, the internal 2 amps fuses hold for about 10 minutes(boiler not running) and 'bar' warning light flashes but the pressure is fine. then blow. Replacement fuses blow immediately.
It appears as though some resistance builds up?
