i have an "Alpha he cb33" combi boiler when we put the heating on it will stay on for a while then trip out mains, we leave it for a couple of hours and try again, it will be ok for about an hour then electric will trip out again. I have noticed that the pump gets hot, is that normal or could the pump be the reaon the electric trips out.
Any help would be greatly appreciated, thanks
