O.k., so I've changed the AAV and the PRV now but the pressure is still dropping to 0.5 when cold. Any more ideas?? I haven't pumped up the pressure to the expansion vessel as I can't see the valve. Can anyone help with that one? +++++++++++++++++++++++++++++++++++++++++++++++ I've...

I have a Glowworm Swift Flow 80 that recently had a new fan due to the whole thing failing. Fault was still intermittent so a plumber came and had a look and said that the AAV was missing a rubber seal, so allegedly fitted one. It then turned out that the PCB needed a few dry joints sorting...

I have a Glow Worm Swift Flow 80 that keeps dropping the pressure down to about 0.5 to 0.7 PSi when the heating in not on. When it's on, the pressure can go up as high as 3 Psi. It all seems to work o.k. but could I have a problem. I've bled the radiators and they seem fine so I'm just...

No, just keep adding bits in the vain hope that someone may helpwith my problem. I've took the PCB out this morning as it all failed again overnight, and there are a couple of dry joints, one especially bad around the flow switch points. I'll try and solder and test from there.

Had a man round today. Scratched heads a bit. Now working, but only after pressing on the PCB. it seems that only half the board was working before that, but now it seems o.k. Fingers crossed. I'm assuming it is a possible dry joint underneath but has anyone else got any ideas?

Pressure sorted. Turned it up to 3 then released it quickly. Seems like the release valve didn't shut properly but does now. But we still have a boiler that doesn't fire. Any ideas?

7 Year old glowworm swiftflow 80 (honeywell) has recently got a bit noisy and last week, out of the blue stopped heating either when the hot water is on or when the central heating is on. It sounded like a classic fan issue, so I've changed the fan for a new one. It worked straight away for...
