Hi all, hope someone can help.
Our boiler no longer produces hot water, the central heating still seems OK. Turning the HW tap on produces warm (not hot) water, after a while the boiler starts banging violently before the gas supply is cut. I can't get the solenoid on the diverter valve to do anything. Also worth noting is the pressure gauge which is reads between 0 - 1 bar, is this normal? When turning the hot water tap on the demand light comes on, thus the flow switch is OK. Anyone know what could be going on, any test I can do?
Cheers, Robo
