There is a place to drain leftover water from, along with a dirt cup at the bottom of our machine. If I start getting an odor, it helps to drain it. I have, when I noticed a problem, taken a little Clorox cleanup on a rag and wipe the large gasket in the door with it. I don't use much cleaner, and I don't do it often, as I don't want the gasket to dry out. But it help kill any mold.
