Bosch classixx 1200 washing machine strange noise

[GRUNT16V]

Hi
As title the machine makes a arking noise when its spinning
When the spin cycle slows down the noise goes away , am I right in
Thinking that the brushes in the motor have gone ??
Any help greatly received
Thanks

Just stripped it again and found it was a noisy brush issue all sorted thanks
