My SIME Friendly boiler will only produce domestic hot water when the central heating is on. I am told it may be a diverter valve problem.
The spindle in the diverter valve does rise and press in the microswitch when a tap is switched on but the water does not really get hot.
Will changing the diaphragm or microswitch cure this or does it mean a new valve. Where is the best source for a new valve?
