Pressurise Greenstar 30CDi

[John Barrow]

Hi everyone.
I have a Worcester Greenstar 30cdi boiler and I need to recharge/depressurise it.

unfortunately it has neither an internal filling link (key fitting) or an external braided hose as shown in the manuals.

what it has is three valves with slotted heads and black plastic shrouds and that’s all. All are currently open - Slots parallel with pipes.
Presumably I need some combination of these valves open and closed to lift the pressure gauge off the stop and out of the red, but I don’t want to simply experiment.

Does anyone know what these three valves are for or just how to recharge the system.

Many thanks

John

Have a look around your hot water cylinder for the filling loop.

As @terryplumb says post a pic of where your HW cylinder is

Wow ! Thanks Terry and Ian for such fast responses. Terry you were spot on. Tucked away, I missed it on my first look around - I guess I wasn’t expecting to find it there, so far from the boiler.
I’ll know next time ! Only had the place a few months and still learning the quirks.

Open that black handle tap 1/4 turn till the pressure guage is between 1 and 1.5 Bar then close again
