How to Clean a Self-Cleaning Dishwasher Filter

In the world of modern kitchen appliances, self-cleaning dishwasher filters have become a game-changer. These nifty devices promise to keep your dishes sparkling clean without much hassle. However, even the most advanced technology requires a little TLC from time to time. In this comprehensive guide, we’ll walk you through the steps to clean a self-cleaning dishwasher filter like a pro.

Introduction to Self-Cleaning Dishwasher Filters

Before diving into the cleaning process, it’s crucial to understand what a self-cleaning dishwasher filter is and how it works. These filters are designed to trap food particles, debris, and other impurities from your dirty dishes, ensuring that your dishwasher runs efficiently and delivers spotless results.

Why Cleaning the Filter Matters

Over time, the filter can become clogged with accumulated gunk, affecting your dishwasher’s performance. If neglected, it may lead to problems like:

  1. Reduced Cleaning Efficiency: A clogged filter won’t effectively remove debris from your dishes, leaving them less clean than desired.
  2. Foul Odors: Accumulated food particles can start to emit unpleasant odors, making your kitchen less inviting.
  3. Potential Damage: If left uncleaned for too long, a dirty filter can strain the dishwasher’s motor, potentially causing costly repairs.

Now that we understand the importance of maintaining a clean dishwasher filter, let’s get into the step-by-step process of cleaning it.

Materials You’ll Need

To clean your self-cleaning dishwasher filter effectively, gather the following materials:

  • Gloves: Protect your hands from any lingering debris and cleaning agents.
  • Screwdriver: You may need to remove screws or clips to access the filter.
  • Old Toothbrush: Perfect for scrubbing away stubborn residue.
  • Vinegar: An excellent natural cleaner that can break down grease and mineral deposits.
  • Warm, Soapy Water: For a thorough clean.

The Cleaning Process

  1. Safety First: Ensure your dishwasher is turned off and unplugged before starting the cleaning process.
  2. Access the Filter: Depending on your dishwasher model, you may need to remove the lower rack or unscrew a cover to access the filter. Refer to your dishwasher’s manual for specific instructions.
  3. Remove Loose Debris: Before removing the filter, use an old toothbrush or your gloved hand to remove any loose debris like food particles and grime.
  4. Detach the Filter: Carefully remove the filter from its housing. Be gentle to avoid damaging the filter or the dishwasher.
  5. Soak in Vinegar: Fill a basin or sink with a mixture of equal parts water and vinegar. Submerge the filter and let it soak for about 15-20 minutes. This will help break down any built-up grease and mineral deposits.
  6. Scrub the Filter: After soaking, take the filter and use an old toothbrush to scrub away any remaining residue. Pay special attention to the nooks and crannies.
  7. Rinse Thoroughly: Rinse the filter under warm, running water until all traces of vinegar and debris are gone. This step ensures your dishes won’t have any lingering vinegar smell or taste.
  8. Reassemble and Run a Cycle: Put the filter back in place, reattach any screws or clips, and reassemble your dishwasher. Run a short cycle with no dishes to ensure everything is working correctly.
  9. Regular Maintenance: To keep your self-cleaning dishwasher filter in top shape, make it a habit to check and clean it every month.


Cleaning a self-cleaning dishwasher filter may seem like a paradox, but it’s a crucial step in maintaining the efficiency and longevity of your dishwasher. By following these simple yet effective steps, you’ll ensure that your dishes continue to sparkle, your kitchen stays odor-free, and your dishwasher runs like a well-oiled machine.

Don’t wait until your dishwasher gives you trouble; make filter maintenance a part of your routine. Your future self will thank you for it!
