This question is regarding Triton T90xr Pumped - Shower Spares

Triton T90xr Not heating water.

The shower is pumping water. The pressure changes as it should when the temp dial is adjusted. There is power going to the Thermal Cut Out however, when the heating is on, there is no power to the elements.

I have replaced the heating can with a working new one. I have tested and confirmed that the micro switches and the TCO are working. I even replaced the TCO as a precaution with no improvement.

Is there a second TCO at the Terminal block/PRD?

I'm at a complete loss on this one.

I'm pretty sure I have installed everything correctly as I tagged and photographed everything beforehand. I restarted the unit with both dials to the cold settings and allowed it to run for 5 mins before trying the heat.

From whatyou say it should work!

 

However ifyou can just go through this check list.

Power tothe terminal block

Power atboth sides of the TCO

Power tothe elements when it is switched on

Check theoutlet Thermal Cut Out this is a black disk with two wires going to it and itis mounted on the out let pipe  (The bit between the heating tank and thehose)

Examine theconnections closely if you see any discoloration / signs of overheating thenthe TCO needs replaced.   

 If itis a new tank and the elements have resistance it must heat up

If all ofthese are OK send me a few photos of the wiring to [email protected] and I’ll see if i canwork out where the problem is

Just to follow up...

I managed to get the shower to work. The problem I found is that the mechanism in the flow valve assembley was not rising high enough to make contact with the micro switches. I solved this by attaching extenders to the switchs (i.e. I glued part of a tile spacer to each lever.) I'm guessing the problem is with the flow valve now, but rather than just replace this I thought I'd ask if you know of another reason that could lead to this.
