Thanks for reply Don,
I have watched every youtube video for every make of washing machine brushes, none of which look like the brush holders on the above machine.
I believe it is a WMA42154 motor.
On your model you normally replace the whole motor end frame, Part Number 096809 so it’s not the simplest or cheapest of brush change jobs. Alternatively, they do sell carbons with bare leads that can be soldered in to the old end frame. If there is a local shop that sells washing machine spares you could take the motor in and ask them to do it.
