My boiler is making a banging noise, 3/4 bangs and then it turns itself off. It waits a while before trying to fire up again, when the banging noise happens again.

Some times the system will not do this and function fine.

Any ideas??

Thanks.

Sounds like the pump has stopped. Undo the centre screw (it'll dribble) and see if the shaft spins by poking a small screwdriver in.

Or it's short of water. Check the header tank, bleed rads and any points near HW cylinder.

Thanks Chris. I will check those things. I have already bleed the rads.

Is there any other specific points that need bleeding apart from the Rads??

........any points near HW cylinder. There's usually one on the upper of the two pipes which come from the boiler into the cylinder. Depends on layout of course.
