Triton Cara power shower

My shower goes hot and cold intermittently. I have been told it could be the TCO is faulty. Can I get a replacement part. Is it replaceable by a reasonable DIYer.

The things to check first are:

1 That the main valve coming into your house is fully open.

2 Then check that the valve on the line to the shower is fully open.

If these valves are not fully open then there may not be enough water getting to your shower to cool it properly, it overheats the safety device cuts in (TCO) and turns the power off to the elements until it cools down and it all starts again!


Make sure that the shower head is clean and clear, that the hose isn’t kinked (this can happen just behind the hand set where it is difficult to see) also check the inside of the hose although it can look OK on the outside it could have collapsed internally


The other possibility is a faulty flow/stabilizer valve not allowing the correct amount of water into the shower.

I am often asked “Is this a DIY job” to be honest I can’t answer that, because without knowing someone, it isn’t possible to assess their skills?

I should say that most jobs on showers although relatively easy (from my point of view) can be fiddly and an extra pair of hands, long thin fingers and the strength in your hands of an all in wrestler are a help!

The secret is, observing very carefully when things are taken to bits, their order and orientation, taking notes and/or photos as you go can also be a help.

When you are working with electricity and water so make sure it is switched off and turned off before you start.

If you think you can do the job but aren’t just that confident, it may help to buy the part and compare it to the faulty part, you will then be able to see where the screws, wires, nuts, or washers etc. go, if then you think it is to complicated, at least you will have the part when the plumber or electrician arrives.

We will always be here to offer help and advice if you run into a problem, however it is not the same as being on site where we can get the overall picture, if you are still not sure, now is the time to call in a professional.
