Gregory - you have asked this question before and it was answered - somebody pointed you at a youTube video on the subject - and they poked fun at you for not finding the video on your own.
Now I poke fun at you for not bothering to act on the original advice.
Go to your last question - copy and paste the URL that points to the youTube video that shows how to change brushes on a Miele washing machine - watch the video.
If you need help in understanding what YouTube is or how to copy and paste a URL then ask another question in the appropriate category.
Good Luck..., August 2015
