I have the same issue as many others that have posted about this. After a wash cycle, there are bits of brown residue at the bottom of the machine, sometimes sticking to my clothes. Recently, i was away, and after 2 1/2 weeks, the washer was filled with this dirt after doing a load of laundry and i had to run a Pure cycle 2x before i could wash again. The Pure cycle also results in a lot of this residue after it runs. My machine is 8 years old, and this has been going on for several months. I am dilligent about cleaning the machine, and running the Pure cycle periodically. I noticed that Samsung has responded to each of these posts with a link for a private message, so please provide so i can get this resolved.
