How do I repressurise my Vaillant boiler?

Turn off the boiler and let it cool. Locate the filling loop (a silver flexible hose beneath the boiler) with a handle valve and isolation valve. Open the isolation valve with a flat-head screwdriver by turning anticlockwise until aligned with the pipe. Then open the handle valve anticlockwise to allow water flow. Watch the pressure gauge and stop when it reaches between 1 and 1.5 bar. Close the handle valve first, then the isolation valve, both clockwise. Restart the boiler and check it operates normally.
