How to Remove Mold from a Dishwasher: A Comprehensive Guide

When it comes to maintaining the cleanliness of our kitchen appliances, the dishwasher often takes center stage. It’s a modern marvel that saves us time and effort, but what happens when mold decides to make itself at home within this essential kitchen companion? In this guide, we will delve deep into the issue of mold in dishwashers and provide you with comprehensive steps on how to effectively remove it. Say goodbye to mold-related worries and hello to a sparkling, hygienic dishwasher!

Understanding the Mold Issue

Before we jump into the solutions, it’s crucial to understand the root of the problem. Mold in dishwashers is a common issue caused by a combination of factors, including:

  1. Moisture: Dishwashers are inherently moist environments, creating an ideal breeding ground for mold and mildew.
  2. Food Residue: Leftover food particles can accumulate, providing nutrients for mold growth.
  3. Warmth: The warm, humid atmosphere inside a dishwasher is perfect for mold spores to thrive.

Now that we know why mold can be a problem, let’s explore how to eradicate it completely.

Step-by-Step Guide to Removing Mold from Your Dishwasher

1. Safety First

Before you begin tackling the mold issue in your dishwasher, ensure your safety. Turn off the power supply to the dishwasher and disconnect it from the electrical source to avoid any accidents.

2. Empty the Dishwasher

Remove all dishes, racks, and utensil holders from the dishwasher. This will give you better access to the affected areas and prevent any obstruction during cleaning.

3. Preliminary Cleaning

Start by using a damp cloth or sponge to wipe away any loose mold or mildew on the interior walls, door gasket, and racks. Dispose of the cloth or sponge carefully to prevent spreading spores.

4. Remove and Clean the Filter

Dishwashers have filters to catch debris. Remove the filter and clean it thoroughly using warm, soapy water. Scrub away any mold or residue, ensuring it’s completely free from contaminants.

5. Clean the Interior

For a deep clean, mix a solution of equal parts water and white vinegar. Apply this mixture to the interior surfaces, paying close attention to areas prone to mold growth. Leave it on for about 10-15 minutes before scrubbing with a soft brush or sponge.

6. Address the Gasket

The rubber gasket around the dishwasher door can harbor mold. Clean it using a solution of baking soda and water. Scrub gently to remove any visible mold and odors.

7. Run an Empty Cycle

With all components cleaned and reassembled, run an empty dishwasher cycle using a cup of white vinegar in the detergent dispenser. This will further sanitize the dishwasher and eliminate any remaining mold spores.

8. Prevention Measures

To prevent mold from returning, make it a habit to leave the dishwasher door open after each use to allow proper ventilation. Regularly check and clean the filter, and remove any food debris from the interior.


A mold-infested dishwasher is not only unsightly but also unhygienic. By following these comprehensive steps, you can effectively remove mold from your dishwasher and ensure it remains mold-free in the future. Remember, prevention is key, so practice good dishwasher maintenance to enjoy clean and spotless dishes every time.
