Mira Event XS thermostatic

My shower is several years old and has suddenly developed a fault, it starts up ok but after a minute or two the water stops and motor continues. If i leave it awhile and retry it repeats this fault. Any advice appreciated.

You have a faulty Solenoid valve which will need replaced, see link below.

Thank you for the prompt reply.

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

I am looking to check the filters and possibly change the solenoid, I obv need to turn the water supply off. However no shut off valves have been fitted, I have tried turning off the main cold water supply to house but the shower still runs! Is this the hot water supply from the loft tank? Am I right in thinking I need to run the loft tank empty, tie up the ball valve to enable me to stop the supply to shower?

Yes there should be valves on the outlet of the cold water storage tank, if there are no valves then you need to turn of the valve to the ball valve or tie it up and drain the tank.

Well I found the tank valves and isolated the supply, cleaned the filters and changed the solenoid successfully! All seemed well but after three showers the water temp went crazy, Very Hot, had to turn temp down to 3 which still left it quite hot! Also shower water pressure seemed higher? Any thoughts?

Check that the valves to the shower are open and the hot and cold filters have not blocked.
