Ok thanks for that.
What you need to do is pull the washer out and from there remove the back panel.
There at the bottom you will see the motor.
Take this off and you need to check the carbon brushes.
On this motors you need to split them. Theres 4 bolts on each side. Remove these and pull the motor apart. But first draw a line in maker pen across the motor so you now which way round it goes.
Then remove the front part.
Then the middle.
The your left with the carbon brush holder. Check to see if they are worn down. If so then they will need to be replaced.
But first look at the armature on the motor. If theres a big line around it in the middle then its probberly taken the motor out and wont work if you just replace the brush module.
As when you see that line on the armature you need to replace the motor. But they are very very expensive and not even worth fixing. You could get another washer for the price of a motor in these.
But check the brushes first as if it just that then they are about £70 just for the part.
If you need anymore info just get back to me.
