To clean a dishwasher filter, remove the serviceable filter, rinse away food debris, and reinstall it as your manual directs. Check the manual first because removal and locking steps vary by model.

A clean filter helps catch food before it circulates or reaches the drain. If dishes remain dirty or water drains poorly, a clogged filter may be one cause, but check the spray arms, drain area, and manual too.

How do you clean a dishwasher filter?

Turn off the dishwasher, remove the filter as directed, rinse it, and put it back securely. Use your model's manual for the exact steps and any cleaning products or tools it allows.

1. Switch off the dishwasher and let any hot parts cool.
2. Remove the lower rack if it blocks access.
3. Find the filter at the bottom of the tub.
4. Open and lift it out using the manual's instructions.
5. Rinse away loose food debris under running water.
6. Check for damage or debris around the filter opening.
7. Reinstall the filter and lock it into position.
8. Replace the rack and run a rinse cycle if the manual recommends one.

Many filters have a screen and a cup or other pieces. Keep track of how parts fit together, and don't pull on anything that doesn't release with the described motion.

Where is the filter, and how do you remove it?

The filter is usually in the bottom of the dishwasher tub, often below the lower spray arm. Its shape and removal method depend on the model.

Take out the bottom rack and look near the spray arm. If you can't identify the filter, use the model number to find the right manual before touching the parts.

Some filters twist out, while others use tabs or a different locking method. See how to remove a dishwasher filter for removal guidance.

Don't assume that another dishwasher's instructions apply to yours.

How should you rinse and check the filter?

Rinse loose food from the filter and inspect the mesh for buildup or damage. Use only a soft brush or mild soap if your manual says those are safe.

Hold the filter so water can carry debris away from the screen. Don't push food farther into the mesh, scrape it with a knife, or use a wire brush that could damage it.

Check the filter cup, screen, and nearby opening for broken pieces or trapped debris. Remove visible debris gently, without reaching into areas your manual says to avoid.

If the screen is torn, the cup is cracked, or the filter won't lock back in place, stop using the dishwasher until you've checked the manual or contacted support. You can compare dishwasher mesh filter replacement options if your model calls for a new part.

Can you clean a dishwasher filter without removing it?

You can wipe away loose debris you can reach, but that doesn't replace cleaning a removable filter. Follow the manual before reaching into the filter area or running a cleaning cycle.

Remove visible food from the tub floor with a damp cloth. Don't pour cleaner into the filter opening or try to dislodge hidden debris with a sharp tool.

What if cleaning the filter doesn't fix draining or dirty dishes?

Check the drain area and other dishwasher parts after cleaning the filter. A clogged or damaged filter is only one possible cause of poor draining or food left on dishes.

Look for visible debris near the filter and check that the lower spray arm can move freely. Follow the manual for cleaning the spray arm or other removable parts.

If water remains in the tub, the drain hose or another part of the drain system may need attention. For countertop models, see how to clean a countertop dishwasher drain hose.

What replacement filter could fit your dishwasher?

Choose a replacement only after confirming the part number and model compatibility. Filter shapes and locking features vary, so compare your existing part and check the dishwasher manual before ordering.

The eHuangTools 645038 drain mesh is described for some specific dishwasher models and replacement part numbers. Confirm your model is compatible before choosing it.

The Cenipar W10872845 filter cup is described as a washable pump filter cup for compatible Whirlpool and Kenmore dishwashers. Check the listed replacement numbers against your model.

The AMI PARTS W10872845 filter cup is described for compatible Whirlpool, Kenmore, Amana, and KitchenAid dishwashers. Verify the model and locking-tab orientation before ordering.

How can you keep the dishwasher filter clear?

Remove large food scraps before loading and inspect the filter on the schedule in your manual. This can limit debris reaching the filter, though it won't remove the need for routine care.

Scrape plates into the trash or compost before loading. If you load stainless steel items, first check whether stainless steel is dishwasher safe.

Don't pre-rinse unless your dishwasher manual recommends it, since model instructions vary.

Clean the filter sooner if you see food collecting on the screen or notice a change in drainage. Keep the lower rack and spray arm clear so water can circulate.

When should you call for service?

Get help if the filter is damaged, won't come out without force, or the dishwasher still drains poorly after the manual's checks. A service technician can inspect parts that aren't meant for routine user removal.

Stop if you see broken plastic, a torn screen, standing water that remains after cleaning, or an error code the manual says needs service. Don't reach into the pump or disconnect parts unless the manufacturer instructs you to do so.

For basic care, follow the manual's filter schedule and cleaning method. For repair questions, give support your model number and describe what you found around the filter.

Frequently asked questions

How often should you clean a dishwasher filter?

Check your dishwasher manual for its cleaning schedule. If it gives no interval, inspect the filter regularly and clean it when you see food debris or buildup.

Households that rinse less food off dishes may need to check more often, but the right schedule depends on your model and use.

Can you clean a dishwasher filter with dish soap?

Use only cleaning methods allowed by your dishwasher manual. Many removable filters can be rinsed under running water, but the manual should say whether mild dish soap or a soft brush is suitable.

Avoid harsh cleaners or abrasive tools unless the manufacturer specifically permits them.

Why is my dishwasher filter stuck?

A filter may have a locking ring or tabs that require a particular turn or lift. Check the manual for the removal direction and do not force it with a tool.

If it remains stuck, contact the manufacturer or a qualified service technician.

Do all dishwashers have a removable filter?

No. Filter designs vary, and some models may use a different filtration system or have parts that aren't intended for routine removal.

Check your owner's manual or model support page before trying to take anything apart.
