Worcester Bosch Greenstar 30 CDi - Pressure loss

[Antics]

Hi all,

Recently moved into a new house and noticed the Greenstar boiler has low pressure on the dial.

Quick Google suggests using a key, valves, or fill loop to increase the pressure. Only problem being is I don't have either of those things.

Any help would be appreciated.

Cheers.

If you look underneath you will need to remove the white plastic cover if you can see the valves this is already removed

Right two pipes there should be a white square connected to the two brass valves don’t touch this yet report back if you see this or post a picture up

Is this the filling loop please? (Next to the water cylinder)

Yep that’s the one open one inline with the pipe and slowly open the second till you hear water your looking for around 1.2 bar
