    No Hot Water unless Central Heating on

    but if the HW comes on all ok when CHW is on then diaphragm or sticking pin seem good possibilities?

    No Hot Water unless Central Heating on

    Vaillant 242/1 E If the central heating is turned on then hot water can be operated ok. If the control is turned to just Hot Water then when a hot water tap is turned on nothing happens. Is it the diaphragm or diverter? thanks
