My problem is that when I switch CH on nothing happens all switches are in the correct position.Nothing seems to happen no start up or anything
I have no problems running hot water. Any ideas gratefully received.
Apart from the obvious one ditch it.

No demand from clock or roomstat (if you have one) or you havent switched the winter/summer switch on the front
