My wife noticed some black crud on her scrubs after washing them. So, being the great husband and handyman that I am, I went on the internet and did a search for black crud in a Samsung washing machine. There were many, many links to the problem.
The solution ended up being a tear down of the tub to clean it. It took me about two hours to disassemble the washer, clean it and put it back together. There was a lot of crud under the tub and under the agitator.
So, if anyone else here has the same problem there is a solution. Sorry, my phone was dead and I didn't get any pictures. Just envision the inside of a P-trap on the kitchen sink and you'll get an idea of what I had to deal with.
