Help needed: electric shower

[alastair84]

Hi does anyone have knowledge about electric showers?
We have a Triton Caselona 2 and basically there is no hot water.

There is no problem with water flow/pressure in our area.
The lights come on, the water flows, but it's cold.
There is no water leakage.
I *think* no problem with water heating elements as when the temp knob is turned all the way to hot, hot water does come out but it's scorching. Then turning the knob slowly anticlockwise (to reduce temp) the water suddenly switches to cold.

After googling, I'm thinking that it's just the TCO (thermal cut out) that needs replacing.
Am I right? Thanks in advance to anyone that can help.

There is next to nothing in an electric shower
Open it up and take a look (make double sure power is off!) thermal cut outs tend to burn out and they visibly melt
This is the most common issue with electric showers

Odd though that it does work at very high temperatures

Might be the thermostat if it isn't the TCO.

thank you for your speedy replies. I couldn't find a replacement thermostat so just went for a spare TCO on the spare parts webpage of triton.

will open it up tomorrow (with power isolated) when the new TCO turns up tomorrow, and have a look, and try to replace the TCO.
Will take a picture and ask for more help if i get stuck.
thanks again.

Yeah basically the heater is running full whack all the time and it's just the flow control that dictates how hot the water comes out. Wierd that it should just cut off suddenly.
