my bar pressure guage is at 0 what shall i do?

Hi Jake

The only thing I can suggest is that you locate the filling loop [which usually has a small lever] and turn it to the left, to allow water into the system. I turn mine off once it reaches 1 bar [Worcester 240]. Water pressure usually reduces over time although if there has been a sudden loss of pressure, you may have a leak in the system.
