Hi, I,I am having hot water problem on C28 boiler. A new plate heat exchanger, valve and diverter motor was installed recently and the boiler was working fine. However now after few days, I am not getting hot water, it is a bit warm but the pipe going to radiators is burning hot. I guess the valve spindle is not being pushed correctly? I have removed the actuator motor and do not see it doing anything regardless of whether there is a demand for hot water or central heating.
My question is that if I removed the actuator motor from the valve and then demanded hot water, should I see the little spindle inside the actuator motor come out? I am not seeing the spindle move at all whether I demand hot water or central heating. Is there a way to test the actuator motor directly with ac mains supply. The connectivity between the motor and pcb seems fine (all 3 wires). Any help would be really appreciated. Thanks
