I must be doing something right cause my Splendide Ariston model stacked washer has never had an odor. I just went and stuck my head in the washer and it smells like the Tide detergent I use for washing. I've never cleaned the front seal other than wiping it after each load and have never left the door ajar on the washer or dryer. My washer has the stainless drum and I'm assuming yours does as well. The bleach idea sounds logical to me.
