What causes the Ravenheat 10E fault?
This fault occurs when the water pressure inside your boiler exceeds a safe limit, usually because the heating system has been overfilled via the manual filling loop. It can also be caused by a faulty tap on that filling loop leaking water into the system or an internal failure of the expansion vessel which normally helps manage pressure changes.
