I have a 28c combi about three years old, It has developed a problem in that the hot water works fine but the boiler is on all the time i.e. the fan is running and the pump but does not fire up for the central heating but the boiler does fire up for hot water ok. I have changed the mech timer and it has no other controls attached. Water pressure is fine no leaks, diverter valve is not stuck and the motor works, also no fault codes.
I really do not want to go and throw parts at it as I really do not have the money so I would like to try and sus it right first time.
And baxi are not helpful at all.
1. boiler will not swicth off when clock is in off position
2. hot water works fine
3. when it called to heat rads it doesn't
Any ideas?
