Glow-worm 30 ci?

On my Glow-worm 30 ci. the pressure indicator is showing .9 bar and i am trying to increase it by turning the green control as it says on the boiler but nothing is happening .
Can anyone help?.

I tried the same and it did not work, I then found a filling loop in the pipework below the boiler ie. a flexable pipi with a tap at each end
