Hi i gave a saunier duval sd30e combi boiler. I bled the radiators yesterday and have got home to a low water pressure light flashing on my boiler and the pressure gauge showing 0- any ideas

topping the pressure up with the filling loop. would be a good start.
if that means opening the valve with the black handle i have tried that
see if the filling loop that you tried, which will have a braded hose.attached.has a screw driver slot on one of the valves.try turning that.usually though most filling loops have a handle at each end.hence the sugestion of the slotted valve.

point it into a bucket and tutn on valve
