Quick Answer

To clean a dishwasher filter, turn the dishwasher off, remove the bottom rack, unlock and lift out the filter, rinse it under warm water, scrub gently with a soft brush, clear debris from the filter well, reinstall the filter securely, and run a rinse cycle if needed.

Supplies Required

  • Dish soap
  • Warm water
  • Soft brush or old toothbrush
  • Microfiber cloth
  • Gloves optional
  • Owner manual optional

Safety Precautions

  • Turn the dishwasher off before reaching inside.
  • Watch for sharp glass, bones, or metal pieces near the filter.
  • Do not force the filter if it does not unlock easily.
  • Check the manual before removing unfamiliar parts.
  • Avoid harsh cleaners that can damage plastic or seals.

Step-by-Step Instructions

  1. Step 1

    Empty lower rack

    Slide out the bottom rack so you can reach the filter area.

  2. Step 2

    Unlock the filter

    Twist or lift the filter according to your dishwasher design.

  3. Step 3

    Rinse loose debris

    Use warm running water to remove food particles.

  4. Step 4

    Scrub gently

    Use dish soap and a soft brush on greasy or stuck-on residue.

  5. Step 5

    Clean the filter well

    Wipe the area under the filter and remove visible debris carefully.

  6. Step 6

    Reinstall securely

    Lock the filter back in place so it sits flat and does not rattle.

  7. Step 7

    Run a short cycle

    Run rinse or normal wash empty if odor or residue remains.

Practical Example

Example: Your glasses look cloudy and the dishwasher smells musty. You remove the cylindrical filter, rinse away food debris, scrub grease with dish soap, reinstall it, and the next cycle drains better.

Common Mistakes

  • Forgetting to lock the filter
  • Using a wire brush
  • Running dishwasher without the filter
  • Ignoring broken glass
  • Using bleach with other cleaners
  • Waiting until odor is severe

Troubleshooting

Filter will not twist out

Check the manual and do not force it; food debris may be blocking the lock.

Dishwasher still smells

Clean door seals, spray arms, drain area, and run a cleaning cycle.

Dishes still have grit

Check spray arms, loading pattern, detergent, water temperature, and filter seating.

Water remains at bottom

Clean filter and drain area; call service if drainage still fails.

FAQs

How often should I clean a dishwasher filter?

Many households benefit from monthly cleaning, or more often if dishes are not scraped first.

Can I run a dishwasher without the filter?

No. The filter helps protect the pump and keeps debris from recirculating.

Why does my dishwasher smell?

Food debris in the filter, drain area, seals, or spray arms is a common cause.

Should I use vinegar?

Vinegar can help with odor in some cases, but follow your dishwasher manual and avoid mixing cleaners.
