Hi i have a problem that i have not hot water, but my central heating works fine, does it sound like i need a new diaphragm or a new diverter?? many thanks

It could be divertor valve/diaphram or the miroswitch assembly connected to the divertor quick test turn on hot tap press micro switch manually if boiler fires problem is divertor valve if not would then probably be hot water sensor or microswitch itself last resort is pcb all parts are availble usually from stock
