Hi
I hope someone can give me some advice. When i turn the hot tap on only cold water comes out. The boiler fan fires up but there is no ignition. I have changed the diaphragm but it wasnt perished. To get hot water i have to first turn the central heating on and then turn the hot tap on. The boiler then stays on. The problem is the microswitch not being made when just on hot water. Could this be due to the heat exchanger being slightly blocked.
Thanks
Mick
