How can I fix my boiler it starts up then starts to bang?
How can I fix my boiler? The boiler lights up ok then you can hear the water boiling to much then it starts to bang the red light comes on and shuts the boiler down. The boiler is a Potterton Suprima
I'm no expert, but it sounds like your pump isn't getting the water away fast enough (its boiling and banging in the Boiler) can you turn the pump up? can you hear the speed of the pump change? if not the pump may be duff
