This question is regarding Mira Sport 10.8kW - post 1998 - Shower Spares

Thermal switch keeps going after few weeks

Any reason why thermal switch would only last 3. Weeks, it's the third switch on this shower.

When fitting a new TCO listen to the shower, after it has completed its first on/off cycle, if when it is switched off you hear it continuing to heat (Noise like a kettle starting to boil) this will mean that there is a switch or a relay that is stuck in the on position, this is keeping an element energised and this is probably what caused the original TCO to fail.

If this is the case replace the faulty switch or relay and make sure that you switch the shower off at the isolating switch when the shower is not in use because this may cause the new TCO to fail.
