I had the exact same gross problem! Bleach did nothing. What did work finally was adding a small bottle of Hydrogen Peroxide (3%) to the hot water when it filled for a self clean cycle. I do it like 1 or 2 times a month depending. Good luck!
I have been having the same issue as well. I have to be washing my clothes up to 3 times to remove the brown flakes/residue. I do self clean at least every 15 to 18 loads. Here is an attached picture after the self clean. So much residue. This is a real headache. I suppose to be feeling happy for having clean clothes, but it is the total opposite. Help, please!
Same issues with our WA50M7450AW. We bought this one after the recall on the last one. My daughter has a mold allergy, if this is making her sick and Samsung knew they had a problem I'll be extra mad.
As with MANY others on this forum, I have an issue with my top-loading Samsung washer (WA45H7000AW/A2) where it leaves black dirt at the bottom of the drum after washing. No amount of "self-clean" will fix this (unless you're telling me it will take more than 10 times in a row, with bleach, vinegar, etc.). I removed the washer plate and it is filled with a black modly substance that is seemingly trapped (pic showing bottom of washer plate attached). I called Samsung and no matter who I talked to they had ABSOLUTELY NO IDEA ABOUT this issue. Which is strange because...
...on the many forum posts about this issue, a Samsung moderator engages the poster and requests information, ostensibly so that they can provide a solution. Yet there is never any followup stating what the solution is (other than perhaps buying a non-Samsung washer). So this is the last chance before I never buy anything from Samsung again...IS THERE IN FACT A SOLUTION???? (Samsung, please post solution publicly or not at all)

How were you able to remove washer plate?
I'd like to see what's going on under mine.
I was informed a "specialized team" was handling my request 4 days ago and would be in contact.
Meanwhile, my family of five has no clean clothes, towels, etc.
I washed a small load of my old running clothes yesterday since I am not worried about the filth ruining them. Disgusting results. I shouldn't have to inspect every article of clothing after it's washed. I am so frustrated.
First, remove the plastic cap in the middle. Pop it off carefully with a flathead screwdriver.
Second, use a 10mm socket wrench to loosen and remove the bolt. After that, it's a bit difficult to get the plate up but it can be done.
It was gross under there. And that's after having run the "self-clean" feature (with bleach, vinegar, etc) at least five straight times.
This was a last-ditch effort to get an answer from Samsung. But given my experience with them on the phone I predict a new (non-Samsung) washing machine in my future.
