Why does my Bosch 500 series have such a foul odor on the inside? I scrape my dishes and rinse them off before loading. It doesn't smell bad when a cycle is finished, but as the days go by, I notice this disgusting smell when I add dirty dishes. null

Accepted Answer

Clean your filter.

I wonder if your food trap in the bottom has accumulated food residue in it? Does your model have a food waste disposer in the bottom? Also the drainage hose can be installed wrong and accumulate a greasy biofilm in it which can make inside the dishwasher smell between cycles of using. I know someone that this happened to, and they had had a professional install it. It has to do with the way it is looped so as to also prevent siphoning dirty water from the sink. The repair person they called installed a new drainage hose even though the older one was only about two years old. In California, you need a special aerator to perform an anti-siphoning function. Don’t know about other state regulations. Let us know if this bit of advice finds and solves your smelly dishwasher problem.

mine does this sometimes and I fix the problem with 2 lemon/lemonade koolaid packets. remove all dishes and flatware and empty 2 small packs of koolaid and run a cycle 
safe to do as little or often as needed. I do this method once or twice per month

Just leave the door open a crack between cycles - just like you do on your washing machine for the same reason.
This work very well, and why Bosch does not say this in their instructions is beyond me.
