Worcester Greenstar boiler zero pressure and not moving up

Postby kathydon » Mon May 03, 2021 11:05 am

Hi,
I've tried to increase pressure, followed all the instructions, but the pressure does not move and remains flat at zero. Is there anything at all that I've missed.

Hi kathydon
Assuming you have a sealed system you will need a filling loop in place and will need to open both valves at either end of the filling loop. There may be extra isolating valves where the filling loop connects so look for ones with slotted tops.
Failing this it’s time for the Gassafe person to visit.
