Flexicom 30cx - H/W but no C/H

[Last plumber]

S30/31 is no demand from Heating side, as you probably already know.
When the Boilers arrive from new they are linked out on 24V side normally so they will work without any controls by using the user interface.
If the mode button is not working at all and the harness from the user interface is good, then it sounds like the interface is faulty.
I haven't seen this of course and as you know, it's difficult to diagnose faults on the forum sometimes. It's a bit like discussing things with someone over the phone.

Are there no fault codes?
Have you tried linking L-R since you took the pressure down?

I totally understand what your saying. If you were there on site, You'd have most likely figured this out in a very short space of time. I've had a chat with a few other people at work and they reckon it could be down to the interface as well. Some were left scratching their heads in wonder why you can't control the C/H setpoint from the display itself with the removal of an external demand.

I really do wish this boiler was different or at the very least, bloody well working. I'm hearing some proper horror stories about the Glow Worm 24/30cx's.

Not good at all.
