filling combi boiler

[nalle59]

Can someone enlighten me ,our worchester greenstar 42cdi combi boiler lost some water preassure due to radiator leak. I turned the filling key to the lock position on the inlet valve before filling from the DHW inlet knob, however no water can be heard coming in allthough all isolating valves on both the DHW inlet and CH return connections are open. The boiler needs just little more preassure and heating works fine as well as water.
I have done this previously and do not know what the problem is ,could it be airlock?

With the filling key fully home and locked, you are turning the white sqare inlet valve are you.

Yes the white key is fully in the locked position and key still in ,and no water going in when i turn the white knob ,usually you can hear the water going in and also see the pressure rising .I turned the key to unlock positon afterwards and now cannot get the key out ! we also have Magnaclean fitted ,could it have something to do with it?

cant see what your doing wrong...

put the key in...turn to lock..open square bit on the left of key.

do you have hot water? (cos its fed from the same cold your trying to use for the central heating top up)

Have now filled it to one bar ,did not turn the white screw far enough but now can't get the key out seems to be jammed in, I quess have to leave it in till boiler service next year ,won't do any harm I suppose.
