Job done today. Switch wasn't that dirty. Some particles came out but nothing drastic. Operating pressure is back to something more sensible, 1.4bar.

That's why I want to remove it, to clean out the muck which is causing F9 fault for which I constantly need to jack up the pressure slightly. It's at 2bar from cold now.

Hi steelmasons, any further info on my question? Cheers.

I wish to drain down boiler to clean pressure switch on Glow Worm Flexicom 18sx boiler, but which drain valve would I use as there are two, one on flow and one on return? Also is the pressure switch easy to remove and reinstall?
