What is a dishwasher filter?

A dishwasher filter traps food particles, debris, and other residues during the cleaning cycle. Found at the bottom of the dishwasher tub, this small part helps maintain the dishwasher's efficiency and hygiene.

The primary functions of a dishwater filter are to:

  • Trap food particles: It prevents large food debris from recirculating onto clean dishes.
  • Protect the pump: By catching particles, the dishwasher's pump is protected from potential damage.
  • Improve water quality: The filter helps maintain clean water throughout the wash cycle. This is especially important if you want to remove and prevent hard water stains.

Knowing how to clean your dishwasher drain filter is essential for several reasons:

  • Enhances cleaning performance: A clean filter allows for better water circulation, resulting in cleaner dishes.
  • Prevents odors: Regular cleaning stops the build-up of food particles that can cause unpleasant smells.
  • Extends appliance lifespan: A well-maintained filter reduces strain on the machine and its other components.
  • Ensures hygiene: A clean filter prevents the growth of bacteria and mold in your dishwasher.

Step-by-step: How to clean a dishwasher filter

If you're wondering how to clean a smelly dishwasher, start with the filter. A clean filter is crucial for maintaining your dishwasher's performance and preventing unpleasant odors. Here's a step-by-step guide on how to remove and clean the dishwasher filter:

What you'll need:

  • Warm water
  • Mild dish soap
  • A soft brush or old toothbrush
  • Microfiber cloth

Disclaimer: When cleaning your dishwasher filter, always reference the manufacturer’s guidelines.

1: Identify your filter type

Dishwasher filters come in two styles:

  1. Self-cleaning filter: These have a grinder that pulverizes food particles. They require less maintenance but are typically noisier.
  2. Manual filter: These have a mesh screen that catches food debris and needs regular cleaning.

To determine your filter type, check your dishwasher's manual or the manufacturer's website. You can also look for a removable cylindrical part at the bottom of the dishwasher tub, which means you have a manual filter.

2: Empty your dishwasher

You'll need to completely empty the machine to clean your dishwasher filter. Remove everything, including any utensils, dishware, and the racks. This gives you clear access to the filter.

3: Remove the filter

Find the filter at the bottom of the dishwasher. It usually looks like a short cylindrical tube. Twist to unlock it and gently remove it from the machine. Some filters have two parts: a cylindrical upper filter and a flat lower filter beneath it. Remove both if present.

4: Wash the filter with soap and water

Clean the filter under warm water to remove loose particles. If it’s stained or has stuck-on debris, you can use mild dish soap and a brush or sponge to gently scrub the mesh filter for a thorough clean. This helps remove stubborn food particles and can even help get rid of hard water stains.

If you notice any holes or damage in the filter, it may be time to replace it.

5: Reinstall the filter

Once clean, rinse the filter thoroughly to remove all soap. Dry it with a microfiber cloth, then replace it in the dishwasher. Make sure to lock it securely back into place.

After cleaning your filter, consider using Finish® Dishwasher Cleaner to deep clean your entire dishwasher for optimal performance.

How often should you clean your dishwasher's filter?

How often to clean your dishwasher's filter depends on how much you use it and the manufacturer's recommendations. Depending on how much you use it, you might consider cleaning or at least checking your dishwasher's filter at least once a month.

However, some suggest cleaning at least every three to six months. Always refer to your dishwasher's manual for specific guidance.

Even if you don't notice a decline in performance, unpleasant odors, or visible debris in the filter, regular maintenance helps prevent build-up, ensures efficient cleaning, and extends the life of your appliance.

Signs your filter needs to be cleaned

With your dishwasher filter hiding behind that bottom rack, it's easy to forget about it. Here are some not-so-subtle hints that it's time to roll up your sleeves and clean your dishwasher filter:

  • Visible build-up of food in the filter
  • Water not draining properly or clogging
  • Unpleasant odors
  • Visible food stains or remnants left behind after washing
  • Food stuck in the sprayer arm

If you're nodding along to any of these, it's probably time for some filter maintenance. When you clean the filter, you're essentially eliminating the need to unclog a dishwasher. It's easier to clean a filter regularly than to deal with a fully clogged dishwasher down the line.
