With the actuator in position, the springs sometimes don't move the valve head at all towards the closed position, and sometimes only part way. The spindle in the valve body is easy to move by hand, so I can only assume it's the actuator assembly stiffening up. I've ordered a new assembly...

Thanks oilman. I've put the actuator back in position with its cover off. When I put the CH on the actuator moves across to open position, but when I switch off the CH the actuator only partially moves back towards the closed HW position. The valve body spindle can be turned with my fingers, so...

Hi everyone, many thanks for your help. It's much appreciated. I've removed the control panel and lifted off the actuator. The spindle on the valve body moves freely about an eighth of a turn (which I guess is OK). However, the problem is, I think, with the final gears underneath the synchron...

Thanks Cider, When I power down boiler the valve lever doesn't move at all. I remember when it used to spring back to HW position but it won't move at all now on its own. The lever is loose-ish and can be moved to either position manually, where it just stays. However, no matter what position...

sorry to add something extra, but if I allow the boiler to heat up, switch off the hot water and central heating then open a hot water tap, the hot water should flow via the hot heat exchanger, with the pump running. The pump runs, but the hot tap still runs cold. Help!

Hi, I've got a Worcester 20/25 oil-fired storage combi boiler. It has gone faulty, in that although the central heating (sealed system) works fine, the domestic hot water runs cold. I have checked the installation manual that came with the boiler. If I switch off the central heating at the...
