I always leave the lid open after washing each week. In doing so, I've never had problems with odors, either in the wash tub or on my clothes. The washer is in a second-floor utility room where no one sees it anyway.
When I first moved to the Twin Cities and was renting a room from a senior citizen couple, the gal always closed the lid on her Maytag Dependable Care when she finished washing. My clothes and bath towels picked up a dirty, musty smell from washing in that machine. It was awful, but I didn't dare say anything since she was a touchy, moody woman and World War III could've resulted.
