Mira play still keeps cutting out!

This definitely sounds like a solenoid fault which is part of the flow regulator

A few things you can try.

The things to check first are.

1 That the main valve coming into your house is fully open.

2 Then check that the valve on the line to the shower is fully open.

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 is not 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.

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

It is really unusual for new solenoids to go wrong when they are new however not impossible.
