I have a worcester combi boiler. It was flashing to reset it as it had gone off even though it should be on. I press reset it starts for about a minute then switches back to reset again. Previously when I have pressed reset it stays on and starts working but it won't stay on now. So there is no hot water or heating. The pressure bar is just under one. What could be wrong with it?
Try ading more pressure to approx 1.5 via the filling loop under the boiler(use boiler instructions to locate) then reset again. If no joy you will need an engineer to help locate the fault
