Mira Sport intermittent temperature

Our shower comes on cold for about a half a minute at first, then warms up. We sometimes have a loud whining noise when it's working, and then the temperature is only warm regardless of the setting. However, if the whining noise goes off, the temperature is as it should be. The noise happens randomly without the controls being touched. We have cleaned the internal filter and we have a new hose attachment. Any ideas please?

Forgetting about the temperature turn the showerfrom fully hot to fully cold at fully hot you should have not much more than adribble coming from the hose and on fully cold you should have a good strongflow, if you do not have this difference then you may have a faultyflow/stabilizer valve.
