Im draining down the system and removing a radiator, after capping off the pipework, refilling and starting the boiler, i'm getting eccessive clanging from the boiler before it cuts out. Any tips before i call an engineer? (potterton performa convetional system)

pump is air locked!!!! bleed it by opening the centre screw until water dribbles out the close back up!
