Baxi combi will not restart after changing radiator?

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.
