Triton Topaz T80i

Hi, my old Triton Topaz T80i is no longer produce hot water. Prior to this, when I switched on the electric shower, it made a loud noise for a seconds. Now it doesn't make a loud noise when I switched on but no hot water. How to fix it, what spare part need to change? If I would like to replace with a new one, which model that suit the layout of Triton Topaz T80i ? Please find attached the picture. I don't when was it fitted as it is already there when I moved in 3 years ago. Many thanks.

If the shower is absolutely cold then I think you may have a faulty Thermal Cut Out

A faulty TCO will have no continuity across the two terminals (The black thing on top of the heating tank)

Therefore a good TCO will have power at both connections and a faulty TCO will have power at only one.

(The function of the TCO is, if the water over heats it cuts the power off to the elements)

See Video.

If there is some heat it may be a faulty element in the heating tank (there are two, three in most 10kw showers) you can check them with a multi meter you should have a reading of around 12>18 ohms.

If you have power to the elements and no heat it's probably the elements, no power to the elements then it's probably a micro switch.


If you don’t have a multimeter we sell them at £10 each with a guide on how to use them for checking and testing the various parts of your shower.


Apart from helping to fix your shower, they are really useful for checking you have a power supply to appliances, for checking fuses, letting you know much power you have left in batteries

(so you know if they are dud or not) and lots of other jobs, in short they are well worth the £10.
