GLOW WORM 30 CXI

[Ramraider16]

HI, JUST WONDERED IF ANYONE COULD SHED ANY LIGHT ON MY PROBLEM WITH 30CXI. I DRAINED THE WATER FROM THE HEATING SYSTEM AND WHEN I WENT TO REFILL A COUPLE OF HOURS LATER, THE WATER WOULD NOT FLOW WHEN THE FILLING TAP WAS OPENED. THE HOT WATER FLOWED THROUGH (COLD) BUT THE HEATING SIDE DOES NOT FILL AND WHEN I SWITCH THE POWER ON THE RED LIGHT FLASHES AND ZERO PRESSURE DISPLAYED. I'VE OPENED THE RADIATOR BLEED VALVES BUT NOTHING HAPPENS.
ANY IDEAS? [/b]

The filling valve may have sheared off inside (cheap part) requiring replacement or the mains pressure is very low and you will need to add a seperate filling loop arrangement.

HI, I'VE SORTED IT NOW. AS YOU SAID IT WAS THE VALVE ON THE FILLING LOOP WHICH HAD SEIZED. THE MERCHANT WHERE I BOUGHT THE REPLACEMENT SAID THEY SELL A LOT OF THESE SO IT MUST A FAIRLY COMMON PROBLEM, ONLY COST £18 SO A FAIRLY CHEAP FIX. THANKS FOR THE ADVICE.
