The other day most of the radiators downstairs were either luke warm or cold. Had a look online and I think it is the hot water pump.
Left it til today, I wanted to make sure it wasn't stuck and was spinning freely. Isolated it electrically, took the bleed screw off, spun the impeller, put the cover on and turned the CB back on. And nothing. The boiler won't fire up the when selecting CH to on from the controller. The pump isn't running, all quiet.
If the pump is bust, would it stop the CH from working completely?
Could it be the pump or something else?
By pump I mean this sort of thing
