There are quite a few posts on the forum about Triton showers running hot and cold, but mine runs cold all the time.

I have a Triton T90si, which is a tank fed shower, so it has regular water pressure. Its about7 years old, but isn't used every day.

The pump appears to be fine, in that the water pressure is the same as always.

I do live in a hard water area, but we have a well and our water is treated with salt. We never get limescale on our kettle, so I can't imagine its the element that has clogged up.

Can anyone recommend a course of trouble shooting steps?

If its something to do with the thermal cutout switch, does this part have to be replaced, or can it be reset?

The only other thing I can think of is that the problem started in January during the cold snap, but I can't imagine that anything would have frozen *inside* the house.

I think I've sorted this.

This is a filter between the inlet pipe and the pump in the T90si.

I unscrewed this (you can do this, it won't let out any water) and cleaned it out.

When I turned the shower on again, the made a few wheezes and belches, but the hot water returned.
 
Also, when you start it up after cleaning it out, but it on the max cold setting first, and then gradually ramp it up to the normal hot setting.
