I am having the brown residue in my washer as well. I have seen it in the past and thought it was just something on my kids clothes! Reading these posts it looks like it’s mold! I have ran 4 self clean cycles and it hasn’t gotten any better. Were you able to get Samsung to help with the problem??
I am having the same issue with brown residue left behind on clothes after being washed. I have also run the self clean cycle with the 1 cup of bleach, with no success in eliminating the brown mess. When I removed the pulsator cap, the bolt and all around was covered in brown yuck.
I have this same issue. Constant battle with mild, gross brown debris everytime I run wash. Is there a fix? Those of you that are sending your info what are they telling you? I think I'd rather buy a new washer instead of paying for a tech to come out if doesn't fix it.
