boiler emergency?

[suvodka]

after coming home from work today, i realised my combi boiler wasnt working, after i turned it off i then proceeded to try and re pressurize it, on doing so, water started sprouting out, stopping after i turn the valve, after being back in the "green" zone it drops straight back below whenever its turned off, has anyone any idea how to fix this without a gas man??

just had to shell out for my car this week ���
any help much appreciated

Appears to be a water leak.... What is the water 'sprouting out' of?
