We have a Triton T80 shower. When anyone runs more water in the house - such as flush WC - the temperature in the shower shoots up and is extremly hot - compared to the setting. There must be a temperature sensor/thermostat that controls temperature. This is obiously faulty. So when pressure is reduce for a moment it cannot control the amount of heat. I need to find out details of the internals of the T80 and what part needs replacing. Any help welcome - I am a DIY person

Quite common with electric showers. In fact the wife does it to me on purpose!

More down to your water pressure and flow rate not being enough/ water taking the easier route

Mains showers generally have a flow stabilisation valve but this needs a minimum dynamic pressure at the shower of ~ 1/1.5 bar, the higher the better, where it works quite well if a downstairs toilet or cold tap is opened, there is no thermostatic temperature control on the T80 but all showers have a thermal cut out (TCO) that operates at 48C. It may be worth cleaning the inlet strainer with a old toothbrush but if you have continuous low/fluctuating mains pressure then you should consider installing a pumped electric shower like the Triton T90 SR which is a tank fed shower and has its own integral pump.

As John says cleaning the inlet strainer is a good idea, you are basically suffering from low flow through the unit.
Other common reasons are a blocked/partially blocked shower head ( debris or limescale - try cleaning it)
A kinked or ‘ herniated’ shower hose.

Try running shower with no hose or head , if it behaves well - replace these items.

Welcome, any joy with improving things?

At this time of year, with the mains ~ 20C, you need a flowrate of 6.5 LPM to have a comfortable showering temp of 40C, if you reduce the power setting to "economy" which is 5kw on the bigger element, you will get 3.6 LPM which is practically the same as the winter flowrate on two elements and this may give a more consistent temperature just now as the dynamic pressure will be higher at this reduced flowrate.
