How to re-pressurise Worcester Bosch Greenstar 30i

[ckid]

Hi all, hoping someone can help me here.

Not long moved into a new house which has the above boiler installed, no problems with the boiler working but the pressure has dropped and can't figure out how to top it up. According to the manuals there are three ways, a built in loop with a lever you just pull (not there on mine), a key type system (an option that wasn't installed on my boiler) or a flexible hose attachment which I can't see either.

Have attached some images

Many Thanks!

Your filling loop will be located elsewhere ,probably near your hot water cylinder. Look for a silver coloured ,braided hose.

do you reckon it will be that silver braided hose at the bottom left of the picture. I would have never figured this out, thank you

Very likely ,is there a pressure gauge near to it ?

Try looking for the gauge near the red expansion vessel, which looks just out of shot on the 2nd photo.

I can't see any pressure gauge anywhere

Can you post a photo from further back, may be we can see it?

here it is, thank you!

it looks like I just need to open the 2 valves of this silver braided hose and check the pressure going up in the boiler

Correct. The gauge is on the boiler, top up to approx 1 bar.

You can get a new filling loop that includes a pressure gauge. This will help you see what you're putting it up to, if there isn't a separate expansion vessel on the system, with gauge, near to the filling loop.
