The problem could be coming into the house as the triton engineer thought or it could be localised to the pull cord switch or the cable behind the shower. The plumber might have damaged it without knowing. This would explain why it only shows up after the installation. Something is not right and it doesn't seem to be the shower. I wouldn't use the shower in the meantime. If you do change the shower I strongly suggest getting a REC to replace it as he will test everything correctly and issue you with a certificate. The plumber didn't test it when he installed it and it's unlikely he'll learn how in the meantime.

OP Do you have an IR thermometer that you could point around at the rcbo, isolation switch and random parts of the supply cable (don't hold it too far from the measuring point, or you will be measuring outside target area). I also wonder if you have a large voltage drop in socket circuits when shower is running. That might indicate a problem with your mains supply and not limited to your shower supply.

Sometimes the rubber inside the hose can perish & cause a blockage. Take the shower head off & run the shower without the shower head. If you can regulate the temperature then the issue is with the shower head. If none of the above works and assuming you have adequate water entering the shower then you are most likely looking at replacing the shower. A new motor costs around 130 plus installation. A new flow control valve is close to 100 plus installation. A new element is over 100 plus installation. The only part worth replacing is the brushes in the motor. I'm assuming that it isn't the brushes as I wouldn't think the shower would have had enough use over the years as it's a holiday home.
This info re Triton models is really useful, as I've been checking out this thread & others in an attempt to decide what to do about replacing a Mira EliteQT 9.8kW, which is needing repair after 2yrs 5mths. I'm really interested in positive reviews & comments about the Triton T90SR, but I'm in Cardiff & wondered if you could advise re my best option over here / re possible advantages of going for either of these 2 showers as an alternative, i.e. the only Triton electric shower models that Triton UK say their engineers can supply & fit here (for gravity fed system in low water pressure area):
T80si pumped https://www.tritonshowers.co.uk/showers-taps/electric-showers/t80si-pumped-electric-shower or Safeguard Care pumped https://www.tritonshowers.co.uk/showers-taps/electric-showers/safeguard-care-pumped-thermostatic-shower
I'm not prepared to pay £170 odd which is what repair to the Mira Elite would be (especially after reading threads about how bad this model is), but Mira have offered to supply & fit an EliteSE for £339
[I have found a UK supplier for delivery of a T90SR (as eg Woodies don't deliver outside of Ireland) ... but then I'm not confident of finding someone reliable to install, if it's not a familiar model to them]
I'm really keen to replace with a shower that's going to be reliable and last well, so not keen to go for the EliteSE ... hoping you can provide some advice, please
The safeguard is really designed for nursing homes and hospitals. Anyone I've seen install one in their disabled bathroom ends up replacing it with a Triton t90sr when it breaks. Nothing wrong with this model but it's not cheap to repair.
The T90si is known as the T900pi here in Ireland. It's been on the market a long time. Doesn't have a silent motor but nothing wrong with the build quality.
The Triton T90sr silent shower is almost identical to the Triton T90xr that you have in the UK. Anyone able to install the t90xr will be able to install the T90sr. The problem is since Brexit no one wants the hassle of shipping to mainland UK.
I'll try to find someone to fit the T90SR as I think I've found one I can get delivered (Triton uk website tells me the xr is obsolete ... was that not a silent motor either?) ... is it likely to be a big job switching from Mira EliteQT? (wall behind sho)wer unit is completely tiled)
... I do wish those that voted leave would be honest enough to acknowledge the harm being done
Did you mean "The T90si T80si is known as the T900pi here in Ireland"
Yes, thanks for confirmation re safeguard ... I didn't think it was necessary ... thanks loads for the quick response
Triton t80si is a confusing one our triton t80si shower in Ireland was a mains fed shower. Totally obsolete now. In the UK a Triton t80si is a pumped electric shower. It's portrait shaped like a mira. In Ireland they are called t900pi.
Mira elite qt plumbing & electrics are in the same area as the triton t90sr. It's a very simple replacement going from the mira to the triton. Less than 30 minutes work swapping the showers.
very frustrating ... looks like I'm gonna have to give up ideas of switching from the Mira Elite QT 9.8kW to the Triton T90sr 9kW
I've sourced a new T90sr for delivery but am struggling to find anyone reliable for installation (I don't think many are very familiar with fitting electric pumped showers around Cardiff🤔 ... maybe) ... anyone know someone local to me, by any faint chance ... or is there an equivalent discussion board over here?
I've tried to get Triton uk (who supply & install) to arrange fitting by one of their engineers and they've just confirmed (from the pics I sent after taking the Mira cover off, showing water & electric feed-in) that it would be straightforward to install ...
but that they can't do it, as the different kW rating (9.8 to 9) would require some change (??) to the electrical supply and therefore an engineer with part P registration, which their engineers don't have
tearing my hair out
They are the exact same KW.
9.8KW at 240 volt in the UK = 9KW At 230 volt here in Ireland. Mira sell showers here & their 9.8KW is 9KW at 230 volt. Put a 9KW from Ireland rated at 230 volt into a home in the UK with 240 volt & it's a 9.8kw shower
A regular plumber should be able to install the T90SR in less than 30 minutes. Some electricians will install it too but not too many
