Alright people, here's the deal. Yesterday I took the machine apart. I removed the inner tub and cleaned EVERY part thoroughly. There wasn't much gunk inside but that could have been from the tablets, bleach and vinegar I've been running through the machine. Anyhow, I put the unit back together and ran bleach through it with junk towels one more time just to make sure I got everything. Today I'm getting the same smell coming back! What the hell is happening? This is beyond me at this point and I don't have enough time to be playing around with this thing. Unless anyone has any other ideas, this piece of junk is heading to the curb.
