Have you descaled the cartridge?

I can't even get the side cover off to expose the screw to the thermostat control cap 😂 why do they always make these screw covers such hard work. 

I know...I know... :-(

Looking at mi-key's link to the exploded diagram, it appears the round end cap just prises off. You'd just need to take care to not scratch it. It might even pull off with a dry hand.

Or, look around for a plastic spudger of some type. The cap from a Bic biro has a 'pocket' tang - would that do?

I've managed to get the end cap off and I've attached some photos. Am I ok to unscrew that screw with the water on? Im assuming it just holds the top plate on and won't disconnect the cartridge?

Yes - it only holds on the handle. No water will be released.

I don't know if the temp override button will need pressing as the handle is pulled off. I suspect not, but hopefully the handle won't be too tightly fixed on the spindle, so it'll become obvious either way.

Ok I'll remove the cap and see what happens. I'll report back in a few days

Ok I have removed the screw but the handle won't budge. How much force should it normally require? Also should I be pulling the part with the temp number on or just the first part?

Needs a good tug, and might be better done by removing the whole bar mixer first.

Have you tried pulling it with the button pressed in ? it may be you need to get something into the gap and sort of lever the handle off. It may have some scale or something holding it on, or just be a very close push fit

Would I be ok to spray some lime scale remover into the end where the screw is to try and loosen it? I think it's definitely stuck by some build up

Really helpful video, cheers I'll give it another go tomorrow!

Of course, to remove the whole unit from the wall, the water will need turning off!
