Worcester 24i rsf low pressure

[Raf]

hi all ,
I’m a total newbie when it comes to boilers hence hope you guys can help me a bit .

I have Worcester 24i rsf Combi and trying to increase pressure on it with no luck. I watched several videos but can’t find one which shows boiler I own . There is no keys or anything just 6 pipes between boiler and wall all with valves on it and that’s where my question come in , how can I increase pressure which sits at 0.5 bar ?

It won't be on the Boiler, it will be elsewhere.

There will be a silver braided hose somewhere below the boiler, maybe in a cupboard etc

It will look like this
