Dishwasher always has a nasty odor when you open the door

Check whether the smell comes from the main drain. Pull your dish washer drain hose and check.

Leave dishwasher door open for few hours. Hope no rate has died inside the machine.

Run a empty wash several times!

Check the main drain, wher you are connecting the drain hose.

hi,
if you put the unit on the hottest wash this will kill off the odour. after each wash leave the door open for about half an hour so it dries out and doesn't smell. Also make sure the filter is clean and the door seal is clean. this should all help with the odour

There is a product at the grocery store in the detergent area that will take care of this ... find it near the dishwasher products.

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!

This is just a suggestion, run a cycle and after a few mins of it washing, open the door and add a cup of bleach and let the washer run. See if this helps.

Lots of ideas,,, Try cycling the dishwasher without dishes on the hottest setting and about 10 miutes into that cycle..stop it and add 2 ups of white vinegar to the water.. let it complete the cycle..

The problem is that standing water with food byproducts will begin to smell as they break down. Like all dishwahers, there is always a small amount of water that remains in the drain system at all times so it is important to clean the filter trap and to periodically air it out or use the white vinegar method..
Hope this helps you...

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.

MY dishwasher had the same smell coming from it. I discovered that under the bottom of the door against the seal was a build up of dirty rotten stuff. When I cleaned that all out the smell went away

Hello Mimhoff it depends on how much water is down there. The sump area always has a little water in it to prevent the circulation pump seals from sticking. Usually around 1 to 2 inches. If there is more than that, check the slots at the bottom of the sump on the left side for being clogged and check the end of the drain hose to make sure it is clear. If you are getting a moldy/odor from the dishwasher, try running Dishwasher Magic or Tang thru the dishwasher. This will remove any build up of food or detergent from the dishwasher. If you are running the dishwasher every few days and just scraping your dishes, then either leave the door ajar or run the rinse & hold cycle to help keep the odor down. Bosch doesn't reccommend running bleach thru the dishwasher as this can cause damage to the rubber seals. However 2 tablespoons of bleach once a year won't hurt.
