Electric shower goes cool

[steve6501]

I have a Trition Aquatronic 3 shower 9.5kW which has been installed for around 6 months.

My problem is that after a period it goes cool for about 10 seconds and then returns to normal. The water flow rate remains the same so I'm sure its not caused by someone turning on a tap etc (or washer etc). It is set on heat setting 2.

It is as though the shower temporarily turns to heat position 1 and then returns back to full power.

I suspect that there is some sort of fault with the heating unit. I have checked the connections and all are good. The wires to the switch are also sound.

Has anyone else experienced this problem.

thanks

Steve

Do you have very hard water?

 

[steve6501]

No. I have another shower in the main bathroom and that is fine

As an aside - two electric showers?

Anything to prevent them both being used at the same time?

Many newer houses with ensuite bathrooms have two showers so no reason why not to?

Other than the reason that 2 electric showers running at the same time could overload the supply fuse. And if you have an electric cooker, and someone is cooking breakfast while 2 people shower, you're definitely into dodgy territory.

It's generally a bad idea to have 2 electric showers.

Not electric showers. Electric showers are a compromise. If i were buying a new house I'd want a proper shower.

Indeed.

With an electric one as a backup.

Have a look here....
https://www.tritonshowers.co.uk/electric-showers/aquatronic-3-ultra-electric-shower.html
...at the instructions for the main unit and the shower head, where you'll find info on cleaning the water inlet filter and the shower head from what may seem like an alarming amount of limescale deposits. I suffer from exactly the same issues on my Triton. Oh, and if it's above a bath, don't forget to plug the hole as you'll invariably drop a screw into it

Checked the filter.....clean....made no difference.

As said in the first post........the flow of water does NOT change. My thoughts is that the heater can is faulty? Anyone had the problem with any other heater can?

Or maybe the thermal cut out operating?

I can't answer your recent questions but on previous thermostatic shower I had to clean a filter inside yhe unit every couple of months On my newer non-thermostatic Triton, the damn shower head is the culprit; they even give you a special tool to take it apart to clean! Ignore any "rub clean nozzle" claims.... One last suggestion, remove shower head and turn it on and see how the water temp behaves. If its steady, surly must be shower head?
