I have a customer having problems with a Worcester Bosch 240 combi, the hot water does not now work, the central heating works fine and they do get warm water if the tap is turned on whilst the heating is on.
I believe that the problem could be either the water diverter valve micro switch or maybe the diagphram inside the value, any other clues??
