The central heating works fine. The domestic hat water does not. The only way to get dhw is to fire up the ch and then turn on a hot tap. I've just replaced the diverter valve according to advise given to me on another boiler forum site but...no joy
Supplementry info:
1 - Extractor fan starts up when a hot tap is turned on
2 - pressure is 1.5 bar
3 - rising pin on left hand diapraghm rises on ch but doesn't on dhw. If I close the microswitch with the tip of a screwdriver, then the boiler will fire up
4 - the two small dia pipes leading to the diapraghm mentioned in point 3 are clear.
Any advice would stop me going over the edge !!!
Thanks
Mark
