How to Clean a Dishwasher Filter: A Step-by-Step Guide
Learn a proven method to clean your dishwasher filter, boost cleaning performance, prevent odors, and extend appliance life with our detailed, order-by-order guide.
To clean a dishwasher filter, remove the bottom rack, locate and take out the filter assembly, rinse under warm running water, scrub with a soft brush to remove lodged particles, dry, and reassemble. Regularly cleaning the filter improves cleaning performance, reduces odors, and prolongs dishwasher life. Do this monthly or biweekly in households with heavy dish loading.
Why a clean dishwasher filter matters
Maintaining a clean dishwasher filter is essential for optimal performance, savings on water and energy, and a fresher kitchen. When the filter is clogged, water can’t circulate properly, leading to poorly cleaned dishes, longer cycles, and lingering smells. Cleaning Tips emphasizes that a well-maintained filter keeps your dishwasher operating at peak efficiency and helps prevent clogs that force you to run extra cycles. In everyday use, food particles, oils, and small debris accumulate in the filter and surrounding basket. A simple, regular cleaning routine reduces these forces at work, extending the life of seals and gaskets while preserving your home’s overall cleanliness. By adopting a predictable schedule, homeowners and renters can minimize surprises and keep meals looking their best.
The bottom line is straightforward: a clean dishwasher filter translates to cleaner dishes with less effort, less noise, and fewer headaches. This routine does not require expensive tools or specialized знow-how—just a few common supplies and a method you can repeat on a consistent basis. The Cleaning Tips team has found that consistency matters as much as technique; a quick monthly refresh is often enough to maintain excellent results. If you’re new to dishwasher maintenance, start with this guide and adapt the frequency to your household’s loading patterns and water hardness.

Tools & Materials
- gloves(rubber or nitrile; protects hands from hot water and solvents)
- soft-bristle brush(readily accessible toothbrush can work in a pinch)
- non-abrasive sponge or cloth(for wiping and drying without scratching plastics or metal)
- small bucket or bowl(to soak items if buildup is stubborn)
- white vinegar(use sparingly for odor control and mineral buildup)
- baking soda(for gentle scrubbing and deodorizing)
- old toothbrush(helps reach tight corners and filter edges)
Steps
Estimated time: 20-40 minutes
- 1
Remove bottom rack and access filter
Unplug or switch off power if your model requires it, then slide out the bottom rack to gain access to the filter housing. Locate the filter assembly at the base of the tub, which may be a single piece or a two-part setup. Gently lift the filter out, keeping an eye on any clips or latches that hold it in place.
Tip: If the filter is stiff, apply a small amount of warm water to loosen debris before attempting removal. - 2
Rinse the filter under warm running water
Place the filter under a warm stream and rinse away loose particles. Use your fingers or a soft brush to loosen stuck food. Avoid using hot water that could warp plastics or damage seals. Inspect the mesh for tears or holes.
Tip: A quick rinse immediately after scraping prevents set-in residue from forming. - 3
Inspect and assess for wear
Examine the filter for cracks, holes, or bent edges. Even minor damage can compromise filtration. If you notice any damage, plan for a replacement rather than reusing a compromised part.
Tip: Check both the filter screen and the housing for signs of wear, as damage in one area can affect other components. - 4
Deep-clean with gentle cleaners
If buildup remains, soak the filter in warm water with a drop of dish soap for 10–15 minutes, then scrub with a soft brush. For mineral deposits, sprinkle baking soda on a damp sponge and gently scrub the surface. Rinse thoroughly.
Tip: Avoid harsh solvents or abrasive pads that can degrade the mesh or seals. - 5
Dry and reassemble the filter
Shake off excess water, pat dry with a microfiber cloth, and reinstall the filter in its original orientation. Reinsert any clips or latches and ensure a snug seal to prevent leaks.
Tip: A secure fit prevents water bypass and ensures effective filtration during the next cycle. - 6
Run a quick test cycle
After reassembly, run a short rinse or light cycle with an empty load to confirm proper water flow and filter seating. Listen for unusual noises that might indicate improper seating or debris in the pump area.
Tip: If you hear grinding or pooling sounds, stop the cycle and recheck the filter and housing.
Questions & Answers
How often should I clean my dishwasher filter?
Most households benefit from cleaning the filter every 1–3 months, or more often if you notice reduced cleaning performance, unusual odors, or frequent clogs. Adjust the interval based on your load size and water hardness.
Most people clean it every one to three months, depending on use and water hardness.
Can I clean the filter while the dishwasher is in use?

What if the filter is cracked or torn?
A damaged filter should be replaced rather than cleaned. A torn screen can allow debris to pass into the pump, causing damage and poor performance.
If the filter is torn, replace it rather than trying to repair it.
Is it safe to use vinegar to clean the filter?
Vinegar can help with mineral buildup but should be used sparingly and never on seals that contact metal parts daily. Rinse thoroughly after any vinegar use.
Vinegar can help remove deposits, but rinse well and avoid prolonged exposure to rubber seals.
Will cleaning the filter fix odors?
