You'll probably think I'm crazy when I tell you this, but it's completely true. We bought a new house (new to us anyway) and it had a Bosch dishwasher in it. We were incredibly impressed with the cleaning power of the dishwasher, but like many people have commented... it started to stink, even when it was clean and didn't have dirty dishes loaded in it. I did the usual stuff, like checking the hose mounting locations and running vinegar through it. Basically, everything a rational person would do to resolve the issue. Nothing worked. Here's the part you aren't going to believe... if you want to solve the problem, after you are done taking the dishes out of the racks (after it is run & clean) WIPE ALL THE WATER OFF OF THE DOOR BEFORE CLOSING IT!!! DO NOT lift the door and let that water go back down into the dishwasher. We started doing this and the smell has been gone ever since. Crazy as it seems, it's totally true. I don't know if this will work for you like it did us, but it's definitely worth a try. Best of luck to all the fellow Bosch dishwasher owners out there. Eric.
