How to Clean a Dishwasher Filter: A Step-by-Step Guide

A clean dishwasher filter is essential for maintaining your appliance’s performance and preventing odors, clogs, or dirty dishes. Yet, many people overlook this simple maintenance task! In this guide, we’ll walk you through how to clean a dishwasher filter effectively, whether you’re dealing with a removable or self-cleaning system. Let’s get started!

Why Cleaning Your Dishwasher Filter Matters

Dishwasher filters trap food debris, grease, and particles during cycles. Over time, they can become clogged, leading to:

• Poor cleaning performance (dirty dishes).
• Foul odors from trapped food residue.
• Drainage issues or standing water.
• Long-term damage to the pump or motor.

Most manufacturers recommend cleaning the filter every 1–2 months, depending on usage.

Step 1: Locate Your Dishwasher Filter

Filters are typically found at the bottom of the dishwasher, beneath the spray arm. There are two main types:

1. Removable Filters: Common in modern dishwashers (e.g., Bosch, Samsung).
2. Self-Cleaning Filters: Found in older models (e.g., Whirlpool, Maytag).

Pro Tip: Check your dishwasher’s manual to confirm the filter type and location.

Step 2: Remove the Filter (For Removable Models)

1. Turn off the dishwasher and unplug it for safety.
2. Remove the bottom rack to access the filter assembly.
3. Unscrew or unclip the filter:
   • Twist the cylindrical filter counterclockwise (common in Bosch models).
   • Lift the flat mesh filter out of its housing (common in Samsung).

Step 3: Clean the Filter

What You’ll Need:

• Warm water
• Dish soap or white vinegar
• Soft-bristle brush (e.g., toothbrush)
• Baking soda (for deodorizing)

For Removable Filters:

1. Rinse under warm water to remove loose debris.
2. Soak in soapy water or vinegar for 15–20 minutes to dissolve grease.
3. Scrub gently with a brush to remove stubborn grime.
4. Rinse thoroughly and let air-dry.

For Self-Cleaning Filters:

1. Wipe the filter surface with a damp cloth.
2. Pour 1 cup of vinegar into the dishwasher and run a hot cycle to dissolve residue.

Step 4: Reassemble and Test

1. Reinstall the filter securely (ensure it’s locked in place).
2. Run an empty hot cycle with a dishwasher cleaner or 1 cup of baking soda to sanitize the interior.

Maintenance Tips to Keep Your Filter Clean

• Scrape dishes before loading to reduce debris.
• Use a dishwasher cleaner monthly to prevent buildup.
• Check the filter after washing greasy dishes or large meals.

Common Mistakes to Avoid

• Using harsh chemicals: Avoid bleach or abrasive cleaners—they can damage the filter.
• Forgetting the filter entirely: Regular cleaning extends your dishwasher’s lifespan.
• Reinstalling incorrectly: A loose filter can cause leaks or poor performance.

FAQs About Dishwasher Filters

1. Can I run the dishwasher without a filter?

No! The filter protects the pump from debris. Running the dishwasher without it can cause costly damage.

2. How do I know if my filter is clogged?

Signs include:

• Food particles left on dishes.
• Standing water at the bottom.
• Unusual noises during cycles.

3. Are all dishwasher filters removable?

No. Older models often have self-cleaning filters. Check your manual to confirm.
