Hi All,
I am quite new to boilers etc but very competent.
I've spent the past few days with a plumber fitting a used WB 30si. I bought the boiler from somebody who had it in an extension and used it rarely but they showed me it working. It sat in my garage for a few weeks and now its been fitted.
I installed the boiler with a NEST learning thermostat but can confirm this is working fine and there is a Live supply to the ST10-LR when the thermostat is 'heating' so thats confirmed to not be the issue. Everything worked as soon as we fired up the boiler, heating come on etc then i turned down the thermostat and then tried to fire it up again it didnt come back.
Sadly we lost all heat to the CH but the DHW seemed to be fine and fired up the boiler everytime i turned on a tap.
I did a little research and removed the Divertor valve motor (slid out) it seemed to move up and down when the boiler was turned on/off so i dont think thats the problem but with it removed and the boiler powered on both the hot water and the CH is working but constantly, not controllable (via thermostat). So thankfully i was able to get heat in the house but sadly we have no control over it and have to turn off the boiler to cool off.
The arm behind that motor moves, i removed the front of the valve and cleaned the "tongue?" inside the valve.
Im not sure which part is faulty if any now as i find it highly strange that with the motor removed (still plugged in to the power) it circulates properly.
Any help appreciated before i spend a fortune on an actual engineer.
