Glow Worm Ultimate Boiler Pressure

[Tristy]

When bleeding the radiators just now, I noticed two upstairs have cold spots at the top half. I unscrewed the bleed valve, and air did come out with spitting of water. But now nothing comes out of these two. Been googling and noticed people saying you may need to repressurise the boiler.

The pressure gauge on the boiler has two needles. The red points to around 1.5 bar but the black one is on zero. This must mean I need to add more pressure.

But Im not sure what valves to open to add more pressure.

I attach images of my boiler and upstairs tank.

Help

Thanks

No filling loop in your pics. Is there a braided hose anywhere ? Should be beside the pressure gauge .or you may have a header tank.

The only braided hose I can see is the one that enters the top of that red cylinder. You can see it in two pics.

I'll take more pics now.

Checked under the kitchen sink nothing. Checked under the utility room sink (same room as the boiler and found this)

Just under the sink above the shelf. Cold and hot water braided hose for the tap and grey flexi hose from the cold to the washing machine.
