the boiler works fine on the hot water side but when i turn the temp control up for the heating to come on nothing seems to happen, would this be the diverter valve not working properly?
probably faulty controls, i.e room stat or timer. the connection for the room stat falls of pretty easily on this boiler if the case is disturbed, it sit's just on top of the pcb cover.
