This question is regarding Triton T70si - Shower Spares

T70SI not heating water, neon light not coming on

I have power at the ceiling fitted relay switch and through to the live terminal (thick brown cable) on the Thermal Cutout (No.2 on your diagram). There does not seem to be power at any other terminal in the unit. When the Actuator Switch (No.3) is turned on the Power Neon (No.1) does not light up. water flows at all temperature settings and shuts off correctly. However, there is no heat.

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.
