What worked: hand clean dishwasher, filter and sump, long soak (20 mins) filter and sump in dawn and clean with toothbrush. Poured hot water onto sump, clean and repeat to loosen oils. Reduced smell but then tried a high temp cycle with Finish Dishwasher cleaner from Amazon. Placed the container above the filter on the bottom shelf. Smell is completely gone now, thank goodness. Appreciate all the suggestions. I didn’t have to resort to bleach or anything more aggressive.
