When I switch the central heating on, it goes on for a while then switches itself off, leaving the power light flashing green,
If I turn the hot water tap on, the system re-sets itself; same if I switch the system off.
However, when I turn the heating back on it switches itself off again, leaving the flashing green light.
Just prior to this all the radiators have been taken out of the system and washed through before reconnecting them and an additional new radiator has been added in the loft.
The system was re-pressurized with an inhibitor present and bled at each radiator.
The water heating works fine.
