I may have found a fix. The repair man took apart the agitator and I cleaned all the brown gunk out that I could get to. Then we took the whole drum out and I scrubbed it clean from all the detergent buildup. It was shiny aNd new again. We put it back in and I had him put a new agitator In. It was different from the factory installed model but it is the approved replacement part for this washer. They must have improved the design. We put in a new screw and cap. So far so good. You can order the replacement parts with Sears Parts Direct or your repair man can do it for you. Parts were about $160 total. He said just use distilled vinegar on a hot cycle every month in addition to the self clean cycle. Hope this helps.

Thank you for all of your posts. You've answered my questions. It's DISGUSTING. After I'm finished running this last self clean cycle I'm going to take apart the middle circle where an agiataor would be. When I purchased this machine in December of 2015 it was listed as one of 3 top machines in Consumer Reports. Then less than 1 year later it was recalled. I chose to replace with a new washer thinking it was a better option than fixing a machine that could explode. I bought the new version. My mistake. I should have chosen the Bravos like my mom. My warranty is up and I'm terribly disappointed, I'll never purchase Samsung products again.
