I have a Baxi combi 105E boiler and have fitted a new towel radiator.after refilling system (all radiators have been bled and pressure is 2 bar), system will not restart. I have a flashing alarm "low pressure / pump fault".
Instruction manual says there is a valve on top of the pump which needs opening prior to filling however my pump does not have such. Any ideas?

try removing the silver screw in the middle of the pump with the boiler off. it will leak a little water, now turn the boiler on and see if the pump spins. if it does put the screw back in if does not then turn the pump with a screwdriver in the hole to free it. Do this with the boiler off as it start spinning if u do it in the on position.
