Gas Boiler: "Insufficient pressure in central heating system"?
When I reset the boiler, it tries to start for a few seonds but then gives up. A green warning light flashes. I've checked the manual and it says: "Insufficient pressure in central heating system".
it still operates as normal but after few times using heating preasure drops , but if not using heating preasure stays same

you need to bring the system pressure up to 1 to 1.5 bar using the filling loop
