why won't my boiler stay alight?
I have a potterton suprema 70 boiler... boiler won't always ignite properly.. press reset, ignites for few minutes then goes out, green light flashes for several minutes then relights and goes out again. Sometimes works fine, sometimes nothing, no hot water or heating? Had new pump fitted recently, can you tell me what is wrong pls?
PEEDOFF!
