mira sport elec shower - what does a tco unit look like?

I've read previous comments re the overheat light and water running cold which refers to the tco unit. What does it look like? Is there a site that I can refer to that will show me a diagram of the innards of the shower? Any help much appreciated as Mira have quoted £139 to send an engineer to fix the problem which could just be rust and only cost the price if some emery paper to fix! Thanks H

I really couldn't say - I am an expert in nothing I'm sorry to say. But it does sound plausible.

The TCO may be operating correctly - in which case the water would get hot and then very hot for a few moments and then the TCO would open and the water then run cold.

If the TCO were permanently tripped (open circuit) then the water would never get hot.

I guess that these TCO things are self-resetting which is to say that after an overheat situation they cool down and allow things to go wrong again - but I just guess.

If it were my shower I would short circuit the TCO as a temporary test - just for a little while - a few seconds but I'm oblivious to danger.

The question is - is your TCO working correctly? Is the TCO at fault or is there another problem?

Do not look to me for a solution - I am without knowledge or experience.

Good luck...
