I have had this same issue since I bought the washer in 2015. I have used nothing but HE detergent, I run the clean cycle all the time. I had Samsung send someone out one time and they replaced the Tub cover and that did nothing. When I finish a load of laundry I use 4 paper towels to wipe down my machine, it's disqusting and nothing is being done about it. There should be a recall on this.
I also have a washer Model# WA45H7000AW/A2 that is just about 6 years old and also have the brown soft dirt/ residue at the bottom of my washer. I have run the self-clean many times and also ran the spin/rinse setting right after the self clean. So what is the solution to getting rid of the brown residue; beside getting a new washer or completely tearing the washer apart and throughly cleaning all of the parts.
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.
