replacement cartridge - Sirrus TS 1503 Thermostatic mixer shower

I have a Sirrus TS Thermostatic mixer shower that the control nob is extremely tight to shut off.

It turns on ok and moves up between temp levels 4-9 ok, but when shutting off it tightens & sticks between level 3 - 0 down to off position.

I don't want to force & break it, would a replacement cartridge work or does this require a complete new unit?

Do you know if the replacement cartridges are still available? or a suitable substitute?

any advice would be appreciated.

A strip down clean lube and fitting a service kit should solve the problem. There is a video at the foot of this page.
