Re: our Bosch diswasher smells (foul odor) after a wash...
Check that it doesn't stay damp inside. That allows any trapped food particles to get funky. Clean it, wiping door seals and dispenser compartments, clean the filters, especially the drain filter if any. Then run on its hottest cycle with a cup or so of vinegar in it. That should clear up the smell. In future, let the beast get dry inside after use. Normally it will be pretty dry at the end of the cycle, but if you cut short the drying time to save on electricity, then you will have to leave the machine open for a little while, and open a crack all the time.

Do you have an airgap valve on top of your sink or counter? Some times routed through an exterior wall. Their purpose is to prevent dirty water coming back into the DW and sitting. You can tell by looking under the sink as well. Your DW drain should never go directly to your garbage disposal or peetrap.
You might want to check the drain hose. It should be mounted up, or have a loop that is higher that the garbage-disposal port that it feeds into. If it is not mounted up, or have a high-loop, it is possible that water from the sink and debris from the garbage disposal can backwash into the dishwasher, and that would be the cause of the smell. Alternatively, it is possible that the heater is not working at all, so dishes aren't drying, and the water isn't getting hot enough to kill the bacteria, mold, and mildew that can form if the water isn't getting heated during the wash cycle.
First check out your model to see if it has a built in garbage disposal, if so, make sure it is not mucked up.
Run hot water down your sink drain while running the sinks garbage disposal. Pour baking soda down your sink garbage disposal followed by white vinegar. Let it sit and foam. Run hot water down sink disposer while running. When finished:
Run empty dishwasher with no soap, let dishwasher fill with hot water to wash and then pour 1 cup of white vinegar into the bottom and resume wash. Make sure you take it through the dry cycle. When finished, open dishwasher and let it air for a couple of hours, longer if you live in humid area. Hope these steps do the trick.
Likely your drain hose goes into your garbage disposer and does not have a rise before it enters the disposer. You will get backwash from your disposer falling back into your dw causing the odor. Simple fix is to make sure the drain hose travels upward a couple inches as it comes out of the disposer. Thanks
doyou have a garbage disposer hooked in with the dishwasher? sometimes that a problem. run your unit with some vinegar with a hot cycle with no dishes in unit. if you still have odor chech your drain line make sure the water is not backing up in to the lines.let me know if this was helpful with a 4 thumbs post
We had similar type of problem (as well as residual water always left in bottom) and after pulling out the dishwasher, found that the drainage tube was incorrectly installed by contractor. It was laying on the floor behind it with a only a slight rise to the garbage disposal inlet. I suspect this contributed to sewer odors as well a water back flowing into the dishwasher. I disconnected drainage tube so that it went up 24+" and then connected to garbage disposal (creates a loop that blocks sewer odors and back flow conditions). I also cleared out the filter at bottom of inside the dishwasher. The Use & Care Guide suggested using baking soda in China/Crystal mode for 10 minutes, opening the front door and letting it sit overnight. I repeated that for 3 nights and it did clear up the remaining odor. Don't know if this will help your issue or not. Good luck!
Hi Jenny - I had a terrible smell coming from under my sink, and I too thought it was a dishwasher/garbage disposal drainage issue. I used vinegar, baking soda, bleach and hot water on a daily basis. When I cut out the wallboard from under the sink and the smell got even worse, however, there was no sign of any water leaks or evidence of a dead animals. Come to find out, when I had a "friend" cut out a pass through from my kitchen (above the sink) into the den, he cut the pvc exhaust pipe and didn't re-route it nor cap allowing the fumes to escape outside via the attic. Thus, the fumes had no place to go other than down. The smell confused me because I thought it was rotten food or most likely a dead mouse trapped between the wall. The smell was actually causing me to get headaches. It's been almost 24 hours that this was repaired and I already can "smell" the difference. I hope this helps! Good luck.
Try running citric acid (3 tablespoons) through. You can get it from a drug store. Or, run 1/2 cup vinegar through. Do this in both the dish washer and the disposal. After doing this try running some water into the disposal and then see if the next time you run the dishwasher if it still smells. You could be having a problem with water not staying in the drain trap under your sink that is why if you run water and fill the trap, then you will find out if it was the dry trap that caused the smell from sewer gases backing up into the house trough the garbage disposal.
It sounds like your dishwasher does not have an air gap. Newer dishwashers come with an air gap installed, but they can be taken out. A quick fix for this is to:
Check the drain line under the kitchen sink. The drain line is supposed to run from the bottom of the cabinet, and run as high in the cabinet as you can get, (up to the bottom of the counter top) then connect the drain. This is called an air gap, and helps keep a little water in the drain line, which will prevent sewer gases from entering your dishwasher, and garbage disposal.
