Well, my week just gets better and better. Boiler has been playing up for while, but has finally decided to play real silly beggars now !
It's a Ravenheat Fanned Combi boiler (RSF82ET), which I've been having problems getting hot water from.
Several weeks ago, it decided that if I asked it for hot water, it would send some round the radiators too, for good measure! This meant the Hot water wasn't as hot as it should be. The only way around it, was to turn the C/H on for 15 minutes, til the rads got hot, then I'd get nice hot water !
Now it's decided that it won't give us any hot water, just lukewarm water and only when the heating is on. It isn't sensing the taps being turned for DHW and won't work in Hot Water only mode.
Have checked the DHW sensor switch, which appears to be permanently closed (no resistance) - should have thought this should be normally open ?
Suspect the three-way valve is sticking or similar too - could be why it wasn't giving priority to the DHW ? Valve ref (Ravenheat) is 002val03005/0, microswitch ref (GC) is 372899.
Any thoughts/ideas ?
Cheers.
