Triton Millenium thermostatic electric shower

[barnowl]

Hello,
My Triton Millenium shower is about 4 years old and has been working fine until recently. I cannot get hot water, it just runs cold regardless of changing the temperature dial. I dont know if this will help but the water pressure coming through the shower is much stronger than it used to be when it worked. The guarantee is obviously run out and I am not sure who to contact to fix it. Has some part worn out or is it time for a new shower. Can anyone advise me please.
Thanks Barnowl.

These have got to be one of the worst showers triton ever made regarding spares prices and diagnose.

Is the shower staying on the button selected ie low,med,high or jumping straight to cold ?

It sounds like a motorised stabiliser valve issue the valves get stuck in one position.
These showers are best fixed on the triton set price fix.
