Glow Worm 28a Low Pressure

[ScottCampbell]

Hi my Glow Worm Betacom 28a combi boiler is showing low pressure (0.4 bar). Does anyone have any idea how to raise the pressure? I've looked at similar systems to find a solution but I can't find any that quite match my own. There are no obvious blue valves to top up the pressure and the only silver pipe I can find is down below and disappears behind the cupboard under the sink. There is a screw head on the piece which connects that pipe to the copper pipe above, and the line on the screw head is sitting vertically in line with the pipe.

Any help would be greatly appreciated! I can't afford to get anyone out at the minute.

Many thanks,
Tom

Thats probably the filling valve there, should be a handle on it just out of sight of the picture, open it a little till the boiler shows 1.0 to 1.4 bar then close handle back off to where you found it.

Thank you! Well spotted. I was blindly looking for blue handles. There is another above that one and I had to turn both before anything happened, then turned them back to where they were originally. Thanks so much!
