I've had to drain down my system today to sort out a problem valve. It runs on a Worcester 28 cdi combi boiler.
All I've done is drain out the water from the central heating, and filled it up again, but the boiler's playing up now. Is there something I should do with the boiler before starting up again. The pressure is back up where it belongs, but when the boiler fires up, whether it be for heating or hot water, it stays on for maybe half a minute, the goes out.
