Shower Identification and issue

[bernie_eccle]

The shower in the ensuite has started to play up. I now have to turn the tap well into the hot zone. It is also extremely sensitive in that it goes from scalding to freezing in the slightest of twist. Will this be fixable?

I know nothing about plumbing and can't identify the control unit to even find a manual. I am concerned that if it requires replacing I will have to rip the tiles off to gain access.

I would grateful for any advice, links etc

Thank you, that's a great help. I still can't find the exact model but can hopefully work out from there.

Just seen the price of replacement cartridges! Hopefully I can do a bit of descaling

Thanks all. Took the caps and cover off today. Doesn't look too tricky to take out the cartridge however it is held in with grub screws at 12 & 6 o'clock. Not a problem other that I can't access them due to tiles too close to the unit, blocking access. I think I'll need to obtain some kind of multi-tool to chip away part of the tile to gain access.
