Hi guys
I have a Ravenheat combi boiler (CSI 85T) thats about 3 years old, the central heating works fine but the hot water in intermittent. There is a lot of info on here suggesting it could be the diverter valve, but if someone could confirm or suggest other likely causes after I have explained the problem I would be grateful.
The boiler will fire up and give hot water for about 2 mins regardless of whether CH is on or not. The boiler will then go out resulting in cold water, it will then sometimes relight again but then go out again. When the hot water stops the plunger that activates the pressure switch on the diverter valve stays out, if it was a faulty diverter valve would the plunger not go in switching the boiler of? This suggests to me that the problem lies elsewhere.
Thanks
Ed
