Bad smell on dried dishes after being washed.Stale...

Question

After a wash cycle. The dried dishes and glasses both smell like stale water. Its about 5 yrs old or so. I've called both Whirlpool and the detergent compnaies...no help. I've tried Bleach..White vinegar and now baking soda. The bleach helps a bit. According to the Whirlpool..there are no filters to change or clean.
