hi all, ill try to be nice as i want something vaillant cwc240h boiler heating works fine. hot water comes on and of fine except the switch behind the servo wont go back into place properly so heating cant come back on. if i push it manually it is works again. is it a new servo or new diverter valve. thanks.
If the valve is a little sticky, it might not be getting back to the fully retracted position - so can't quite trigger the microswitch.
You bunking off too? Hwz abouts we hang out together? Your shopping centre or mine. Bring your hoodie.
Sorry just had a thought.Look underneath the servo valve and just check that the top part of the water section is not corroded.Sometimes this can stop the small pin moving up and down correctly.If your lucky a drop of lube will sort.
