How to Get Rid of Mold in the Dishwasher

Mold in the dishwasher is a common issue that can lead to unpleasant odors and potential health concerns. It’s essential to address this problem promptly to ensure your dishes come out clean and safe to use. In this comprehensive guide, we will explore the causes of mold in the dishwasher and provide practical solutions to get rid of it. Say goodbye to moldy dishwashers and hello to fresh, clean dishes!

Understanding the Causes of Mold in the Dishwasher

1.1 High Humidity Levels

Mold thrives in moist environments, and the dishwasher’s humid conditions provide an ideal breeding ground. When the dishwasher door is closed immediately after a cycle, it traps moisture inside, encouraging mold growth.

1.2 Food Residue Buildup

Leftover food particles can accumulate in the dishwasher, providing nutrients for mold. If dishes aren’t rinsed properly before loading them, food residue can become lodged in corners and crevices.

1.3 Inadequate Cleaning

If you neglect regular cleaning of your dishwasher, mold can take hold. Mold spores can attach to dirty surfaces, making it difficult to eradicate them.

1.4 Water Leakages

Water leakages within the dishwasher can create hidden pockets of moisture where mold can flourish. Leaking seals or damaged components should be addressed promptly to prevent mold growth.

Prevention Is Key

2.1 Regular Cleaning Routine

To prevent mold, establish a routine for cleaning your dishwasher. Remove any debris from the filter and clean the interior with a vinegar solution at least once a month.

2.2 Leave the Door Ajar

After each cycle, leave the dishwasher door slightly ajar to allow moisture to escape. This simple habit can significantly reduce the humidity levels inside.

2.3 Use Vinegar

Vinegar is a natural mold inhibitor. Place a cup of white vinegar in the top rack of the dishwasher and run a hot water cycle without any dishes. This will help eliminate mold and odors.

2.4 Run Hot Water

Occasionally, run the dishwasher with hot water but without any dishes or detergent. The high temperature will kill mold spores and sanitize the interior.

Removing Mold from the Dishwasher

3.1 Safety Precautions

Before cleaning, ensure the dishwasher is unplugged or disconnected from the power source. Safety should always come first.

3.2 Cleaning the Interior

Use a mixture of baking soda and water to scrub the interior surfaces, including the walls, racks, and door. Pay close attention to corners and crevices where mold may hide.

3.3 Cleaning the Filters

Remove and clean the dishwasher’s filters. Soak them in warm, soapy water and scrub away any debris or mold growth.

3.4 Cleaning the Seals

Inspect the door seals for mold. Clean them with a vinegar solution and a toothbrush to reach tight spaces.

Maintaining a Mold-Free Dishwasher

4.1 Regular Inspection

Periodically inspect your dishwasher for any signs of mold. Early detection can prevent a more severe infestation.

4.2 Replace Damaged Seals

If you notice damaged door seals or gaskets, replace them promptly to prevent moisture from seeping into hidden areas.

4.3 Professional Maintenance

Consider scheduling professional dishwasher maintenance annually. This can help identify and address potential issues before they lead to mold problems.


A mold-free dishwasher is essential for maintaining clean and hygienic dishes. By understanding the causes of mold, taking preventive measures, and following proper cleaning procedures, you can ensure that your dishwasher remains mold-free and your dishes are safe to use.
