Temperature control

Hi, I’ve been called to one of these, turn the shower on it works but really hot, when I try to adjust the temperature the water stops? It’s either on fully hot or it stops. What would be the first thing to check or replace? Regards Garry

First thing to do is check the filters on the cartridge

The next possibility is one of the clutches on the gear wheels is worn and not turning the cold cartridge on or it is stuck

If you remove the gear box cover try to operate the gears with your fingers
