shower running cold but TCO test okay

I have a Florida Plus that has overheat light on and only runs cold. The flow varies when I change the temperature and I have tested the TCO as above out of the shower and it is fine. What do I try now?!

If it is cold and you are absolutely sure that the TCO is OK then there must be no power getting to the elements???

If there is now power to the elements then you could have a faulty pressure switch not allowing the micro switches to allow the power through to the elements or indeed not enough pressure to allow the pressure switch to work.

Thanks for getting back to me. Tested the TCO as per your video; getting 11 ohms across the connectors.

Hi, is 11 ohms the sort of resistance you would expect to get across a TCO? How do I test the pressure switch?

Thanks
