I thought kitchenaid was one of the best brands. I have a kitchenaid professional series and one day I decided to put it into the dishwasher because why not and little did I know all the coating came off. I continue to wipe it making sure my paddle is clean but black stuff kept rubbing off onto the papertowel. So disappointing. I need a replacement!!! And I can’t even use my mixer now for the fear that I’ll kill someone with my baked goods.
