Potterton Combi HE Plus Range
Please help, am at end of my tether with boiler that doesn't seem to want to remain on and won't heat radiators. The burner light sign comes on, the display shows temp rising then as quickly as that all happened the burner indicator light switches off and the number drops right down to 40 again. And then a few mins later the whole thing happens again.

Hi . either your heat exchanger is sludged , the pump is almost gone or your temp stats are faulty. Does it do the same on hotcwater?
