Sounds like you have the same problem as me. When you turn the heating on does the boiler attempt to fire up but then fail?

When i turned the heating on it fired up and worked until it reached the correct temp then it fails to automatically fire again. It also stops working if someone uses the hot water. Does this still sound like the servo valve?

Does that mean i need a whole new Servo valve? If so how much should this cost in Uk £

I have a Vaillant Combi, the Pilot light is lit and hot water works fine, but when the heating is switched on the boiler is attempting to fire up but keeps failing. Any suggestions?
