Hi, I can only get hot water at the tap when the central heating is on. The pressure switch works but the pin doesn't come out to press it.
Any ideas?
Thanks,Roy.
this advice is aimed at giving you an idea of cause of boiler fault
its not intended for you to attempt to repair boiler yourself
rather for you to get someone qualified to carry out repair with the prior knowledge of cause & cost
