Water mix

Only hot water comes out. Cold on full is lukewarm.

It would appear that you need a new thermostatic cartridge.

How would I dismantle the mixer? I can unscrew the collar off the knob but not remove the knob if there's an allen key fixing in there. It's an Aqualisa 300 I think. Thanks for your previous reply.

You need to remove the end cap and then the knob retaining screw if I remember correctly you need to press the temperature override button to remove the knob.

When this is removed you need to remove the cartridge retaining collar then the grub screw.

You also need to check which cartridge you have high or low pressure, it is stamped into the black part of the cartridge.
