My triton T80si electric shower fluctuates between hot and cold at all temperatures, the low presure light does not come on at all. Do you think that this is a thermostat problem or water pressure? The household water pressure is good, and this happens even when the heating and washing machine etc are all off. Any ideas?

This shower has two thermal cut out switches, there is one at the bottom of the tank too, if that one fails then it first starts to cycle hot and cold first before failing completely. Unlike the top main TCO which if it fails or triggers turns off the entire shower, the bottom one just shuts off the elements.

hi, this is a common fault with triton showers that at one time used to appear on their web site but the last time i looked it had mysteriously disappeared. it is referred to as cycling. they recommended that 1. clean the spray head really well. 2. and this is the important bit, take the shower head off and then turn the shower on and leave it to run for not less than ten minutes on full bore. unfortunately they didn't say whether to run it hot or cold, so i do ten minutes of each, it does seem to work, for a while. It is an annoying and built in unwanted feature of triton showers, they all do it but ofcourse they don,t tell you about it when you buy one. It is all to do with the oversensitive safety feature to try and prevent over hot water from burning you. God invented feet for that, you just move out of the way !
