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".

The boiler is a Ferroli Modena 80 E.

Any help would be much appreciated.

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