: The combi boiler failed to produce hot water. Investigation showed a faulty wax capsule and a pinhole in the changeover valve. Parts were fitted and it worked for a while then was fine on heating but the pump will not start for hot water. All of the microswitches appear to be functional.
: HW is fine while the heating is on (pump running)
: I need a circuit diagram and advice please
