Triton T80i Auto Reset

Hi, Our shower has recently started auto reseting itself during operation. So it rund hot, then the auto rest light comes on (NOT the low pressure light), water run cold for a while then the light goes off and the water again runs hot. Is this likely to be a TCO fault, would it show up as open circuit if tested. Thanks Gary

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.


There is a link below that explains the above.

The tco is working fine.
