None of the other suggestions worked for me. We had no problems for years, but a few months ago the area by the dishwasher stunk each time we washed the dishes. I took the dishwasher apart and it was clean. I ran all kinds o of things through the dishwasher and the sink/disposal.

Finally, I tracked it back to the vent under the sink. The vent is designed to let air into the drain/sewage lines so you don’t have negative pressure (this can occur as water is dumped in from the dishwasher, etc.). It is a one-way valve, so it has a rubber gasket that prevents the sewer gas from coming into the house. However, after about 8 years, the rubber gasket had simply worn out. Replacing that vent cost me less than $7.
This is easy to check. Look under your sink. The vent is a pipe that simply points up and goes nowhere, but has a cap about 2-3 inches long that screws into the top. You’ll probably need channel locks to unscrew it. Once you have, see if the rubber gasket on the inside looks warped (our case) or full of crud. You can find a replacement at any hardware store. It simply screws on with some teflon tape.
This has finally solved our “smelly dishwasher” and smelly sink problem that occurred each time we washed the dishes.
