Please can someone help.
My problem has only just started but is causing me a big headache. i'm getting a loud banging noise coming from the pipes directly above the boiler. Although I can here the boiler start up, within a minute it shuts itself off and keeps repeating this process. This applies to both Hot water and the central heating. I've checked the header tank and main tank and they are both full, so there's water in the tanks. I've bled all the radiators and there all ok. However the highest one in the bathroom has no water coming out. This is strange as when the boiler is on and the banging starts loads of air comes out and then water; the boiler then cuts out. If I then try to bleed that radiator with everything switched off, nothing happens, no water - no air, nothing.
Please help.
