How to Remove Black Slime from a Samsung Dishwasher

Quck answer

Cleaning black slime out of a Samsung dishwasher unit is a simple process that can be done using common household items. First, remove any visible debris from the dishwasher. Then, mix equal parts vinegar and water and use a sponge or cloth to wipe down the interior of the unit, paying extra attention to areas with black slime buildup. Next, remove the dishwasher’s filter and rinse it under running water to remove any trapped slime. Finally, run a hot cycle with a cup of vinegar to further clean and deodorize the dishwasher. Regular maintenance and cleaning will help prevent black slime from accumulating in the future.


Dishwashers often become neglected when it comes to cleaning. However, they can become breeding grounds for bacteria and fungus. While this may not pose a significant risk to your health, it can be problematic for those with compromised immune systems. If your Samsung dishwasher has a foul odor, it’s time to address the cause of the problem.

Cleaning Your Samsung Dishwasher: Initial Steps

Samsung advises against using bleach to clean the interior of their dishwashers, as bleach can damage the stainless steel finish. This is also why running a bleach cycle is not recommended. Remove any removable parts, such as racks, baskets, nozzles, and filters (if possible) according to your dishwasher model. Refer to the user’s manual or Samsung’s online database for instructions. Clean these parts thoroughly with warm, soapy water and consider using toothpicks or a needle to remove any debris. Fill your sink with warm, soapy water to wash the parts before putting them back in the dishwasher.

Sanitizing Your Samsung Dishwasher

  • Start by removing any debris near the drain housing. Use soapy water and a rag to clean the area, and disassemble and clean the filter if applicable.
  • Clean all the nozzles and inspect the tiny holes for any debris. Use a toothpick or needle to clear the holes and wipe them with a soapy rag.
  • If there is significant slime in the dishwasher, consider using a stronger cleanser in addition to warm water. After cleaning, wipe the interior with vinegar to sanitize it.
  • Clean the door seal thoroughly with a rag soaked in white vinegar. Pay attention to the rubber seal where fungus and bacteria tend to accumulate. Clean the bottom and inside of the door, as well as the area where the door meets the dishwasher housing, using vinegar or warm, soapy water.

Finishing Touches

Once everything has been cleaned, wash the removable components in warm, soapy water, dry them, and return them to their original positions. Running a self-clean or normal cycle according to your model’s instructions is optional but not essential.

In order to avoid the formation of slime and unpleasant smells in the future, it is important to leave the dishwasher slightly open after each cycle to allow it to dry. It is worth noting that storing dirty dishes in the dishwasher until you run a load can also lead to lingering odors, so it may be necessary to reconsider your approach to loading the machine.
