I have not used my shower for some months (we have three) as I had to regrout and seal it.
I used it yesterday and the water was only tepid on the highest setting. Definitely warmer than the 'cold' and 'eco' settings but when on 'high' turning the knob makes no difference to the temperature. It is stuck on tepid.
Same problem today.
All the lights work as they should; the water flow is excellent. Any ideas what could be wrong?
Possibly a faulty thermostat, but more likely a faulty element in the "tank".
Easy to replace as long as it's a known make, and the parts are available.
These things are hellishly difficult to diagnose. There are several other gubbins inside that may cause this. Sadly, it's often a matter of replacing parts until the fault clears.
Sorry I'm not helping much, but fault diagnosis is often trial and error.
The builder, thought you'd like to know I've just phoned Triton and they are coming out to repair it on Friday. I'm happy with the price, £200 including labour, all parts + VAT, but I could probably buy a new but different shower cheaper.
It's a stress free solution so all good
