mira sport heats but no flow

Hi, the shower has been working fine, but one day there was an "electrical smell" so we shut it down. Now when I turn it on at the fully cold setting it works great, but as you turn up the temperature control the flow slows down, until by the time you turn it enough to make the water nice and hot, it's nothing more than a trickle.

One person told me I need a new micro switch, but someone else said replace the heating tank. I don't want to buy the wrong parts - any ideas out there ??

Many thanks.

Brian.

Either an element has failed or a micro switch has become faulty see below how to check element.

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.

If the elements are OK then check that you are getting power to both of the elements, if there is no power to one of the elements then that is the one that will have the faulty micro switch.
