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

triton opal electric shower low pressure cut out

The low pressure light comes on and the water goes cold but still runs. There is a click each time this happens suggesting some sort of cut out switch. Restarting the shower usually clears it but it is a nuisance and I would like to remedy the fault. Could it be a fault with the thermal cut out or something else

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! This can also happen if there is low flow or low pressure.


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 this may restrict the flow.


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