Water not heating up properly

I have a 10.4 which recently has stopped producing warm water unless its on 7+ on the High setting, at which point it is little more than a trickle.

I have tested the TCO as per your video and there is continuity across the terminals.

Shortly before reaching the current state the shower started to produce very hot water when set on 1 on the High settings, although the temperatures on the Medium and Cold settings where as I would expect them to be. Does this help with diagnosing the problem?

I am reluctant to replace the entire shower as I only installed this a few years ago when the previous NewTeam shower stopped working under similar circumstances.

Forgetting about the temperature turn the shower from fully hot to fully cold at fully hot you should have not much more than a dribble coming from the hose and on fully cold you should have a good strong flow, if you do not have this difference then you may have a faulty flow/stabilizer valve.

Also,


It may be a faulty element in the heating tank (there are two, three in most 10kw showers) you can check them with a multi meter you should have a reading of around 12>18 ohms.

If you have power to the elements and no heat it's probably the elements, no power to the elements then it's probably a micro switch.

If you don’t have a multimeter we sell them at £10 each with a guide on how to use them for checking and testing the various parts of your shower.

Apart from helping to fix your shower, they are really useful for checking you have a power supply to appliances, for checking fuses, letting you know much power you have left in batteries

(so you know if they are dud or not) and lots of other jobs, in short they are well worth the £10.
