I have a potterton Profile boiler, the pilot light is on but i cant get any hot water, even if the water is on constant and the dial is on MAX
Any idea's to the problem before i have to call out a plumber
if the spark stops and there is 240v on common and both other connections on gas valve than it needs replacing. you will need a corgi reg service engineer. if the spark keeps sparking after pilot has light than its the pcb
