FAQs

What does a Thermal Cut-Out Switch (TCO) do?

The TCO is a safety device that shuts off the shower's power if it overheats, protecting the unit and preventing potential injury.

Where is the TCO located?

The TCO's location varies depending on the shower model. Refer to your shower's manual for the exact location.

How do I know if the TCO has tripped?

The shower will stop working or will only run cold water. The shower unit itself might also feel cold.

Can I reset the TCO?

Some TCOs are resettable. Consult your shower's manual. If it trips repeatedly, there may be a fault and you may need a replacement.

Is it safe to replace the TCO myself?

If you are comfortable working with electrical components, you can replace it. However, always disconnect the power supply first. If unsure, consult a qualified electrician or plumber.

What causes a TCO to trip?

Common causes include blockages, insufficient water flow, a faulty heating element, or limescale buildup.

Where can I buy a replacement TCO?

Replacement TCOs can be purchased from plumbing supply stores, online retailers, and authorized Mira dealers.

Does the TCO come with a warranty?

The Mira Thermal Cut-Out Switch 1746.436 is covered by the manufacturer's guarantee.

Troubleshooting

Shower doesn't heat up or stops heating.

Check the TCO. If tripped, reset or replace it (after identifying and addressing the underlying cause).

Shower runs cold.

Check for a tripped TCO. If tripped, inspect the shower for blockages or other issues. If the TCO trips repeatedly, consult a qualified electrician or plumber.
