Hi
My CH boiler occasionally does not start. I've noticed that when I increase pump speed to 3 (normal setting 2) the boiler will immediately start and is OK for some time then. And I can reduce the speed to normal 2.
Seems like the pump gets the signal to start but not starting and then boiler does not start either.
That is for central heating.
Can the pump be faulty?
What else can be a problem?
thanks
