Mira Sport Max 10.8K Cold Water

Hi,



I have a Mira Sport Max 10.8K which is around 2-3 years old.



Fault - Water temperature is cold unless the temperature dial is at Max, then the water is luke warm.



Checks I've made:

1. TCO meters out fine.

2. Elements 'A' & 'B' (see attached image) read around 10ohms.

3. When the shower is operating I get 240v on connections '1', '2' & '4' (see attached image) - no power on '3'.

4. On connector '4' it looks as if there is some heat damage, this can be seen if you zoom in on the image.



I'm guessing that the PCB is faulty, what do you think?



Regards,

George.

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.
