Triton Cara Electric Shower

If the shower is absolutely cold then I thinkyou 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 afaulty TCO will have power at only one.

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

See Video.

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

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

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

Apart from helping to fix yourshower, they are really useful for checking you have a power supply toappliances, for checking fuses, letting you know much power you have left inbatteries

(so you know if they are dud ornot)  and lots of other jobs, in short they are well  worth the £10.

I think in the first instanceyou need to replace the melted section of the blue wire, if you then still havea problem, see below!

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 the overheat safety devicewill turn
the power off until it cools Then it all starts again

We are having a problem at the moment with our ticketing systemit is running words together, we have people working on it!!

If when you switch off the shower at the main isolatorand the shower keeps running then you have a faulty solenoid.

When you switch off the shower at the mainisolator  and the water stops  running, then you have a faulty on/off switchor a faulty PCB or a micro switch that is sticking on.

Sorry for the delay in replying

The normal cause for this problem is the installer not tightening up the terminals fully

I depends how badly the shower has been affected often cutting the wires back and fitting a new terminal block will solve the problem.
