Hi
My combi boiler has stopped firing up when the hot water tap is turned on.
It works fine on central heating, and once the CH is working then hot water is available but it does not go thro the routine of shutting down and refiring for DHW as it should do.
I have been told that this a a diverter valve problem but I am a little unsure if this is true.
It seems to me that there should be something that detects a fall in presure as the hot tap is turned on, and and that this causes the boiler to go into DHW mode... is this the Pressure Differential Valve or Servo Valve ? or is the problem really the diverter valve (this .. of course is the more expensive item !!) thanks for any advice you may give
