I would first like to say I love my mixer, however I don't feel the same about the original attachments.  They absolutely can not go in the dishwasher!  I was doing really well until recently.. my husband of course made the fatal mistake.  They are no longer usable due to the dark gray coating that now rubs off on everything, but magically stays in place no matter how much you scrub them.  I can't really blame Kitchenaid since I knew to hand wash them, however it really is impractical to have something that is destroyed the first time it goes in the dishwasher. I hope they come out with something more durable because unfortunately I am sure this will happen to me again...
