Bosch Washing Machine Smell

I have the same problem with this smell with my Bosch. But I am very sorry to say, I wipe the rubber part of my machine dry after every wash and I leave the door open after every wash, in just thinking (have never heard of this problem before) to keep the rubber part dry, just in case it might cause mold some day. And still my machine has developed this odor. I purchased the Affresh tonight at Sears and im hoping this works. If not, I do plan on checking for water storage (if I can find the drain plug & ect and possibly using the baking soda and vinegar. Thanks so much for everyones help.
