Mira extreme thermostatic

When I turn the hot water up on the dial the shower squeals loudly it takes a long time but with a bit of turning down and slowing up on the heat dial the how water starts to come through. Do I need a new valve assembly to cure this? Please could you advise correct part number so I can order. Thanks.

Difficult without hearing this, however could it be one of the bearings in the motor and pump unit that has dried out.

I think you will have to remove the cover to see if you can establish where the noise is coming from.

Remember to switch of the power before removing the cover.
