The boiler fires up for a very vshort time and then goes out. The flow and return pipes coming of the boiler are hot. Im not getting any hot water or central heating. Am i right in thinking that my pump isn't working....it sounds noisy. There is also a lot of air in the system..please help
On the front of the pump there will probably be a large screw. Turn off power to the pump and then undo the screw and remove it. You should then be able to get a flat bladed screwdriver in and turn the pump to free it up. Put screw back and turn power back on. Does sound very likely to be air.
