A:
I'm sorry to hear there's an odor in your dishwasher. Wiping around the edge of the door, including the bottom edge, and running empty cycles with vinegar periodically are an important part of maintaining the dishwasher. Selecting the Sanitize cycle to help eliminate odor-causing bacteria may also be helpful.
If the drain hose is not installed properly, it's possible the dirty water is not draining thoroughly which could lead to an odor. Please refer to the attached image which is excerpted from the Installation Guide.
If these suggestions don't resolve the issue, please call 800-SAMSUNG for assistance determining whether service may be necessary to clean the sealed areas of the DW7933LRASR, such as under the filter cover or in the water or drain lines.
