I have sour mildew smell problem with my clothes

Look inside the door to the gray rubber ring gasket thingy. Pull apart the sides and look in. Betcha a dollar to a donut there's mold in there. It's a gross, nasty problem whirlpool customer service doesn't give a damn about.That's where water sets after wash cycles. There are tablets call "Affresh" which can be run with hot water for a cycle to attempt to clean out the mold/mildew. Not cheap, not fair, and probably will only be a start to a maintenance type cure if you've had the washer for awhile. May take some manual labor with bleach as well. NOT a sanitary washer. This is an unbelieveable problem with a washer. Piece of ****.

Use about 1/4 cup of white vinegar with your detergent and be sure to put in dryer as soon as the washer is done and use dryer sheets. (letting clothes sit in washer for awhile after it's done washing can cause mildew smell. Hope this helps.
