Can anybody help with the current problem I am experiencing on my glow worm 38Cxi combi boiler.
It is all working fine as when hot water or central heating is called for.
The problem seems to be only when the system is pre-heating the water in the reserve tank. It fires up the boiler and start to heat until the F14 error code appears on the display. It sounds like the water is boiling and I can hear noise in radiator pipes!
