I have a Ferroli F24 boiler the heating and hot water works

Customer Question

Hi I have a Ferroli F24 boiler the heating and hot water works fine but if the heating is on and you turn the hot water on and switch the water back off it won't go back to heating, the radiator light just flashes, but if you reset the boiler the heating will come on as normal again, I think it is either the PCB or the diverter valve.
JA: How long has this been going on? And how severe is the problem?
Customer: Only found out today as it is the first time we switched the heating on.
JA: Do you plan on doing the work yourself?
Customer: Yes
JA: Anything else we should know to help you best?
Customer: No just need to know if this is a common fault you have seen before.
