hi there, im after some advice on my glow worm 30cxi boiler! Recently we had a drop in pressure on the boiler it was showing 0.7 and the red light was flashing, i followed the instructions which were on the casing but still nothing happend, i then read the installation and servicing manual and realised that i probably needed to fill the system back up using the filling loop, when i did this there is water coming out from a brass valve on the far left of the boiler, i have taken the housing off and flapped down the control panel and i can see where the water is coming from it almost looks like a bleed valve, i have asked a few people but no one has been of any help, on the 30cxi do you have an external filling pipe which connects to this valve which is leaking or is it the the valve is broken or some one mentioned an intergral filling loop which is done with a key....im just a bit confused as to what the problem is, if some knows how to fix this i would appreciate the advice or even be able to point me in the right direction.
many thanks
