Someone bought the the stand kitchenaid mixer for my wedding in the end of 2018. But I barely use it cause it’s little heavy and take up spaces. So I always have it in the box and only use maybe 3-4 times. Just recently due to Covid-19, I have to work from home and bake a lot lately. And my flat beater became gray charcoal, after one wash in dishwasher cause I thought it’s stainless steel like the wire whip. So I don’t know what I did wrong cause I put the wire whip in dishwasher too and nothing was wrong with it. I was looking to buy the new one, but then after I looked around and ran into this page where a lot of people have the same problem as mine. So I don’t know if it’s ours fault That we put it in the dishwasher or the product is defected.
