This question is regarding Triton T100xr electric - Shower Spares

alternating between hot and cold

As soon as shower reaches temperature, it trips back to cold then heats up and alternates between hot and cold forever! Have changed solenoid coil and checked all obvious pressure issues. Could it be thermostat and where is this in the triton xr100?

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.

The outlet Thermal Cut Out is a black disk with two wires going to it and it is mounted on the outlet pipe. (The bit between the heating tank and the hose)

Examine the connections closely if you see any discoloration / signs of overheating then the TCO needs replaced.

Also check that the inlet valve is fully open and the inlet filter is clear.
