Redring shower

[Graham.]

The temperature control on an instantaneous electric shower is not a thermostat, it's simply valve that varies the water flow rate. Can you give more details of the problem with model number?

[Jim the Geordie]

The thermostat in my electric shower is playing up so I intend replacing it (or having someone else replace it) I did it myself last time as the model (Active 320) had the exact same layout as the previous model. Is there a way of finding out whether newer models have the same layout so there is a minimum of re-routing pipes ot cables?

There's a parts list and spares available here:

If it's a 'thermostat' problem I'd be looking at the electrical components, possibly the heater, the switches or thermal cutout.

Contact the manufacturer and ask?

It must be a fairly common question (I had the same thing but with a Mira shower), and they probably have a standard answer (maybe even a FAQ on their website).

For a manufacturer, there is a clear commercial advantage in keeping layouts as consistent as possible - changing things only when some "new development" makes it necessary to change things around.

dl the manual for both models. It'll include a pic/diagram

It's not that the temperature doesn't change, it's that it cuts out.The The light dims to the medium setting brightness and it goes cold, before reaching a hot enough temperature for a comfortable shower. Model is Active 320

Is there not one to protect the element though? Brian

[Jim The Geordie]

Almost certainly the thermal cutout. I have one on the original California model, but although I coluld probably remove it from there, I doubt whether I could replace it in the current one whole standing on the edge of the bath. Is it necessary anyhow? I could diconnect it.

I assume it's to avoid the element continuing to run if there's a pressure drop in the water supply, resulting in the water output going overtemp. You don't want to be standing under a shower of boiling water when that happens.
