This question is regarding Triton Aspirante/T80si/Opal Thermal Cut-out (TCO) - 22009860

Triton T80si

Shower Temperature has been going hot and cold, for a couple of days, then this morning it tripped the RCD. Now I have to set it on its highest temp just to get warm water. Recently replaced the Solenoid and the Stabiliser Valve Seal.

It may be afaulty 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 around12>18 ohms.

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

If you don’t have a multimeter  wesell them at around £10 each with a link to an on line guide on how to use them for checking and testing the various partsof your shower.

 

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

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

Regardingthe hot cold cycling

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 then it starts to heat again andso on.

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