Help with Mira Electric shower

Question

I have a Mira Elite 2 Electric shower just over 2 years old.

It has now decided it only wants to deliver cold water.

Turning the temperature dial makes no difference.

Can anyone tell me if it is the thermal switch that has packed up?

Whoever installed it used sealant around the edge of the unit to the bathroom tiles making it air and water tight. I have since learned that this should not have been done.

Could this have caused failure?

Many thanks

Cant tell u what has gone wrong but i'd call a repair geezer. I have has electric showers pack up and been fixed easily & cheaply by repair person. Unfortunately its wear & tear. But I wouldnt mess about with electricity!!
