Cleaning bits of food and foreign objects from a dishwasher filter can be... gross. The fact is that it is one of those out of sight, out-of-mind cleaning projects that often goes ignored until you're reminded by a funky smell, noticeable grease build-up, or bits of food remnants on dishes. Food scraps, grease, and hard water deposits are common debris that can accumulate in the filter and hinder its cleaning performance. As a best practice, you should aim to clean the filter on a regular basis, especially if your dishwasher sees heavy use. Luckily, even the worst of clogged filters should only take a few moments to clean.

You'll Need:

  • Soft-bristle brush (e.g., bottle brush or an old toothbrush)

  • White vinegar

  • Water

  • Bowl for soaking

  • Clean towel or paper towels

  • Flashlight (optional, for better visibility)

  • Dishwashing liquid (optional, for extra cleaning power)

  • Gloves (optional, for handling debris)

  • Screwdriver or pliers (if needed to remove the filter)

1. Turn Off the Dishwasher

  • Turn it off completely by unplugging from the power source.

2. Locate the Filter

  • Depending on your dishwasher model, the filter may be located at the bottom of the dishwasher tub or beneath the lower spray arm. Refer to your dishwasher's manual to locate the filter if you're unsure.

  • Note: Some dishwashers have a self-cleaning filter. If you see a plastic grid or series of holes at the bottom near the drain hole, your machine is self-cleaning and you can't remove the filter. Use the manufacturer's recommended cleaning tablets instead.

3. Remove the Filter

  • Carefully remove the filter from its housing. Sometimes, you may need to unscrew or release clips to access the manual filter. Take note of how the filter is installed to ensure proper reassembly later.

4. Inspect the Filter

  • Once removed, visually inspect the filter for any visible debris, food particles, or buildup. Use a flashlight if needed to see more clearly.

5. Rinse the Filter

  • Under warm water, rinse the filter thoroughly to remove loose debris. Use a soft brush to gently scrub away stubborn stains or buildup.

6. Soak in White Vinegar Solution (Optional)

  • If the filter is particularly dirty or has mineral deposits, consider soaking it in a solution of white vinegar and water. Mix equal parts vinegar and water in a bowl or sink, and let the dirty filter soak for about 15-30 minutes.

7. Scrub Again (if Necessary)

  • After soaking, scrub the filter again with a scrub brush to dislodge any remaining food bits or buildup.

  • Note: Never use a wire brush as they can tear the filter. Rely on vinegar, patience, and elbow grease instead.

8. Rinse Thoroughly

  • Once cleaned, rinse the filter thoroughly under running water to remove any traces of vinegar or soap residue.

9. Dry the Filter

  • Use a clean towel or allow the filter to air dry completely before reassembling it into the dishwasher. Ensure that the filter is completely dry to prevent mold or mildew growth.

10. Reassemble and Replace the Filter

  • Carefully reassemble the filter according to the way it was originally installed. Make sure it's securely in place before closing the dishwasher.

11. Run a Cleaning Cycle

  • After cleaning the filter, place 2 cups of vinegar in an upright dishwasher-safe cup or bowl and run a wash cycle in the dishwasher to flush out any remaining debris or residue. Follow it up with a heat-dry cycle.

How often should you clean the filter if you use your dishwasher five to seven times a week?

With such frequent usage, food particles and grease are more likely to accumulate and reduce cleaning efficiency. So, try to clean the filter every two weeks to maximize efficiency and extend the lifespan of your dishwasher. If you run fewer loads, you're safe to clean the filter once a month.

How often do dishwasher filters need to be replaced?

The lifespan of a dishwasher filter largely depends on the type of filter and the frequency of use. Most dishwasher filters are designed to last 3-5 years before needing replacement. However, if you notice significant wear and tear, or damage, or if the filter becomes heavily clogged and cannot be adequately cleaned, it may be time for a replacement.

Will soaking the filter in white vinegar damage it?

White vinegar is a natural, non-toxic, mild acid that helps to dissolve buildup, break down grease, and neutralize odors. Soaking the dishwasher filter in white vinegar is a safe and effective method but dilute the vinegar with water (50/50) and rinse thoroughly afterward to avoid damaging the filter's materials over time. Overall, white vinegar is a safe and environmentally friendly cleaning method.
