Mira sport electric shower

When you try to switch the shower on do any of the lights go out?

If yes that may suggest a faulty isolation switch.

If no then you are probably right it may be the solenoid if that is the case then I would replace the flow valve complete as it comes with a new solenoid.

See below for how to check for a faulty solenoid.


It may be your solenoid valve, you can check it if you have a multi meter, you should have a reading of at least k3.5 ohms, across the two terminals any less and you need a new valve. (Check the valve in the failed state.) (When it has stopped working!)
If there is power getting to the solenoid and it is not operating then there is a good chance that you have a faulty solenoid.

The video is intended as a guide and does not cover every shower.
If you don’t have a multimeter  we sell them  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 and letting you know much power you have left in batteries
(So you will know if they are good or not) and lots of other jobs, in short they are well worth a few pounds
