Central Heating System Pressure

[droberts1]

I have a Worcester Bosch 28CDi Combi boiler and the system pressure has dropped to zero after I bled the radiators. I have followed the instructions in the manual to boost the system pressure, but every time I turn the grey knob, water comes gushing out.

Does anyone have any idea what I am doing wrong? I'm sure it's something very simple.

Many Thanks

Obvious question is, have you put the white filling key in?

You are not using the key that prevents water gushing out. These are special items for the Worcester brand - you can get them from HRP (aka Parts Center).

If it is in Have you put it in right?.
Looking at the boiler from the front put the key in so it's at the 6 o clock position, turn it anti clock until you feel it go in a bit more, them turn it so it's at the quarter to three position, then open up the valve.

As soon as I posted this, I found the filling key on top of the boiler.

You live and learn.
