    To fix it I step back and power it on / off

    Does this sound like a thermostat problem? Replace thermostat or should I replace the shower.

    Please see pic attached for model.

    Model = Triton T80si


    Thanks

    If your tco thermoplastic cut out had blown then the water would be cold all of the time. Its very likely your heating can / elements are caked with limescale. The t80si is a very old shower and not worth spending 150 on a new element supplied and fitted. You'll get a new triton t80z supplied and fitted for around 300

    Would fixing it as op describes indicate lime scale?

    He's not fixing it. The Tco is doing its job. The heat from the element is transferred to the top of the heating can in the case of heavy limescale. The Tco sits on top of the heating can. So it is because of the extra heat at the top of the heating can that is causing the Tco to kick in. The Tco isn't at fault it is the heating can needs replacing. The Tco either works or doesn't work. There is no in between. If the Tco fails then it will never work again. It is a fuse so to speak. Once blown you'll only get stone cold water till you replace the Tco.

    Thanks for the advice.

    The shower is in an attic and it sometimes stutters slightly.
    There is a good pump down stairs.

    I think it may just be age and needs to be replaced.

    Do some showers work better in a less pressurised place like upstairs?

    My cold/hot taps take a few seconds for water to arrive sometimes as I don't use them much.

    It's intermittent.

    It only goes freezing cold once a month and power on/off cures it.

    Thanks for the advice

    I didn't realise that the shower is in the attic. It could easily be a water pressure problem. If the pressure drops then the pressure switch deactivates & stops sending power to the element.
    Does the low flow light come on when the water goes cold? If it does then it's telling you that the water pressure is not good enough to run the shower safely.
    The triton t80z can run at a lower pressure than most showers. Mains electric showers usually don't work great in Ireland as our pressure is very low in a lot of the country.
    Another solution is to pipe it from the tank & put a small pump on it

    I notice there is a small "low pressure" warning light on it and it doesn't light up when there is a problem.

    If changing it I will take your advice.

    Thanks again
