glow worm 30 cxi combi boiler - no central heating!!?
The central heating no longer works, the hot water is fine though. when i attempt to switch the central heating on, the boiler starts making a noise like its going to come on but then stops and does nothing. what could this be? and what is the fastest way to mend it? xxx
hello, I've had this fault before. It's caused by a low pressure (less then 1.5 bar I think). I can't remember the fix, but do know it's specified in the manual.
Sorry I can't be any more help
