This question is regarding Mira Excel/Select Thermostatic Cartridge - 903.33

shower

I have a Mira excel shower and there does not appear to be enough hot water getting through to the shower head.

I have removed the cartridge assembly and cleaned out the filters and renewed the seals. It still does not allow the hot water through. I can feel the chrome housing on the hot side is very hot to touch but does not reflect this at the outlet. Do I need a new cartridge assembly

Assuming you do not have a combi boiler then it is certainly the cartridge which can be ordered online by clicking on the link below.
