The pain has now chipped off on 2 of these beaters. I did put it in the dishwasher. If I can find the part again, I will not put it in the dishwasher this time. My mother puts her KitchenAid beater in the dishwasher and the pain does not chip on her. In general, I have not liked my mixer. I have to always scape the bowl by hand, because the mixer does not mix well. Otherwise, I get a layer of butter stuck to the bowl, but not in my batter.
