Want to replace motor brushes...any tips on this

I need to also, so please post what you learn. I found several examples for other WMs on YouTube (search brushes carbon washing machine) Note, I was able to get my Bosch Axxis WFL 2060 spin working again with the following quick carbon dust cleaning trick:
1) Unplug WM and tip up to a 45 degree angle and then safely stabilize so you can safely access motor from bottom. No need to take off back or disconnect motor.
2) Using a small tool like a 1/4 allen wrench or medium screwdriver start tapping repeatedly (for 2 mins) on the brush holders, and back metal clips that connect to the brushes, your just moving the dust around really.
3) Next using an alcohol damp cloth clean the motor commutator - on this motor it is easily exposed on one of the sides 90 degrees away from, and in line with brush holders. Hold cloth on commutator and turn motor, this will also make it clear if commutator is damaged. You cloth should be pretty dirt after 2-3 rotations.
Repeat 2 and 3 above a few more times cleaning up all the carbon dust off the commutator and around the brushes.
After that tip down and test again. A more thorough cleaning could be done by removing brushes and cleaning em - but this will buy you a few weeks/months of operation.
