Triton Topaz T80si Only running cold
Just wondering our shower last night just started running cold. There is no low pressure light on and even when we turned the dial to the hottest it is still running stone cold. I've read about a thermal cut out? Could it be this?
Thanks
Becca
Forgetting about the temperature turn the shower from fully hot to fully cold at fully hot you should have not much more than a dribble coming from the hose and on fully cold you should have a good strong flow, if you do not have this difference then you may have a faulty flow/stabilizer valve.
If the shower is absolutely cold then 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.
