How to Clean the Dishwasher Filter in Kenmore 587 161 49401

how do i clean the dishwasher filter in kenmore model 587 161 49401.

A clogged filter often leaves food and odors behind.

Cleaning it restores spray pressure and protects the drain pump.

Manufacturer documentation places the filter under the lower spray arm in the sump.

Routine cleaning takes about 10 to 20 minutes for most households.

As of 2026, hard water increases scale, so read the step-by-step workflow below.

Quick Answer

how do i clean the dishwasher filter in kenmore model 587 161 49401.

Remove the lower rack.

Twist or lift the filter assembly out.

Rinse and brush the mesh, then reseat securely.

Problem, and why a clogged filter hurts cleaning, drains, and your pump on this Kenmore

If the filter clogs, spray arms lose pressure and dishes stay dirty.

Small debris can bypass a damaged mesh and reach the drain pump.

That causes noisy grinding and expensive pump repairs.

Hard water speeds mineral buildup and narrows mesh pores.

Households that skip filter care often see performance drop in weeks.

Stop the cycle before opening the door to avoid injury from hot spray.

How the Kenmore 587.16149401 filter system is built (parts to recognize)

Know three parts you will handle. Learn these names so parts diagrams make sense.

• Coarse debris basket, the outer cup that catches large scraps.
• Fine mesh screen, the inner cylinder that traps small particles.
• Filter cap or twist-lock, the top that secures the assembly to the seat.

The filter sits under the lower spray arm in the sump area.

Look for plastic tabs, arrows, or a raised grip on the cap.

These clues tell you whether you can twist, press, or lift the part.

For background on scale and water quality, check USGS water information for hardness and mineral effects at the national site, which explains why scale occurs in many regions.

Which filter type do you have? Decision branches for this model

If you can grip and turn the cap, the filter is removable. Remove it following the cleaning steps.

If you see press tabs, press them and lift the cartridge straight up. That is a cartridge-style filter.

If the screen is flush with the tub and has rivets or screws, clean in place and call service if corroded.

Quick identification table

For a tidy prep area, keep cleaning tools near the dishwasher in an under-counter organizer, see compact storage options in our under-counter storage suggestions for ideas: under-counter storage tips.

Tools & supplies you’ll need (quick checklist)

Replacement filters for older Kenmore units usually range from about $10 to $60.

If tabs feel brittle or mesh is torn, budget for replacement to avoid pump damage.

Step-by-step workflow, remove, clean, inspect, and reinstall (fast route)

Follow this if the filter is removable and turns with reasonable force. Read each short step and act.

Prep and safety

1. Cancel any active cycle and open the door. The spray arms may still move.
2. Pull out the lower rack and place it aside. Lay a towel under the filter area.
3. If you will access the sump deeply, turn off the power at the breaker for added safety.

If your dishwasher connects to a garbage disposal, clear that knockout first. For drain troubleshooting basics and disposal ties, consult our drain troubleshooting guide for common signals and fixes: common drain faults.

Remove the filter assembly

1. Locate the round cap or handle at the tub floor under the lower spray arm.
2. Grip the cap, twist it counterclockwise about a quarter turn, then lift straight up.
3. If tabs hold a cartridge, press the tabs and lift the cartridge out.

Wrap a towel around the cap if it is tight. Avoid pliers on plastic or mesh.

Clean the parts

1. Separate the coarse basket and fine mesh screen. Rinse both under warm running water.
2. Use a soft brush and mild soap to scrub the mesh from both sides. Do not use metal pads.
3. For scale, soak parts in a 1 to 1 mixture of warm water and white vinegar for 15 to 30 minutes, then scrub and rinse.

Clear spray arms and drain openings

1. Spin the lower spray arm by hand to ensure free motion.
2. Clear clogged spray holes with a toothpick or small brush.
3. Remove any glass, labels, or food from the drain opening and sump.

Inspect and reassemble

1. Check mesh for tears and examine plastic tabs for cracks. Replace if damaged.
2. Reinsert the mesh into the basket the same way it came out.
3. Lower the assembly into the seat, twist clockwise until it locks, and return the lower rack.
4. Run a short rinse cycle to verify normal sound and proper drainage.

Branch A, stuck or seized filter: safe extraction decision tree

If the filter will not turn, answer: try loosening methods before forcing anything.

Warm water and better grip often free stuck caps safely.

Try these steps in order

• Pour warm tap water into the sump, wait five minutes, then try twisting again.
• Wrap the cap in a towel and use rubber gloves for added torque.
• Look for hidden screws or release tabs and remove them carefully if present.
• If it still will not move, stop and call authorized service.

Do not use screwdrivers or pliers directly on the mesh or plastic. Forcing parts can crack the sump and void warranties. If you need help with a fused filter, consult Kenmore service options for guidance: Kenmore service.

Branch B, cleaning an in-place (non-removable) screen, safe workflow

If the screen is fixed, answer: clean it from above without prying.

Fixed screens are usually secured with rivets or screws and will not lift out.

Cleaning steps for fixed screens

1. Remove visible debris with gloves or a soft brush.
2. Use a handheld vacuum set to low to lift loose grit if available.
3. Wipe the screen with warm, soapy water using a soft brush.

For scale, press a microfiber cloth dampened with 1 to 1 vinegar and warm water against the screen for 10 to 20 minutes, then scrub gently. If fasteners look corroded stop and call an authorized technician.

Troubleshooting common problems and targeted fixes

Persistent odor after cleaning, answer: check the sump and disposal connection.

Food lodged under the filter or in the disposal can keep odors alive. Remove debris manually, then run a hot rinse cycle with one cup of white vinegar on the top rack.

Dishwasher not draining or grinding noises, answer: inspect the filter seat and sump.

Small shards or labels can jam the impeller. Remove visible debris and test the lower spray arm for free spin. If grinding continues, stop and call service.

Poor wash results after cleaning, answer: check spray arms and the water inlet screen.

Clogged spray holes or a blocked inlet reduces pressure. Clear spray holes, clean the inlet screen where the home supply connects, and test with an empty rinse.

Torn mesh or broken tabs, answer: replace the entire filter assembly.

A damaged mesh allows grit into the pump and accelerates wear. Order the correct part using the Kenmore model number.

When to repair, replace, or call a technician

Replace the filter when mesh has visible holes or plastic tabs are cracked.

A replacement part prevents debris from reaching and damaging the pump.

Call a technician when any of the following occur

• The filter remains fused after warm water and towel torque.
• Grinding persists after cleaning and reassembly.
• You find broken glass or impeller damage in the sump.

If the unit is under warranty contact authorized Kenmore service before doing aggressive repairs, to avoid voiding coverage: Kenmore service.

Maintenance schedule and quick checklist

Keep this cadence to limit clogs and service calls.

Quick pre-run checklist

• Filter seated and locked.
• Lower spray arm spins freely.
• No visible debris in the sump or drain.
• Run a short rinse cycle and listen for unusual sounds.

If your water is hard shift to a two week spot check schedule. For kitchen surface cleanup after maintenance, our guide on grease removal covers safe degreasers and cloths, follow the "effective grease removal" link for tips: effective grease removal.

Safety warnings, warranty tips, and things to avoid

Avoid concentrated drain cleaners, they can damage plastic and seals.

Use mild soap and vinegar for cleaning and descaling.

Do not use metal scouring pads on the mesh.

Metal will tear the mesh and can send shards into the pump. Replace a torn screen immediately.

Do not force fittings with tools.

Wrap the cap in a towel and use hand torque only. If you suspect warranty coverage contact authorized Kenmore support before performing aggressive repairs.

If trapped moisture causes mold or persistent odors check under-sink conditions and remediate any cross-contamination. For safe mold guidance see our mold resources: mold under-sink guide.

Expert tips to speed the job and prevent repeat clogs

Warm water loosens grease faster than cold.

Brush gently from the clean side toward the dirty side to push particles out.

Trim large food scraps at the sink before loading dishes.

Use the hot rinse cycle monthly with one cup of white vinegar on the top rack to reduce film and odors.

Store a toothbrush and gloves near the dishwasher for quick weekly checks.

Quick checklist before you finish

Filter cleaned, reassembled, and locked in place.

Lower spray arm spins freely when nudged.

No visible debris in the sump, drain opening, or around the seat.

Run a short rinse cycle and listen for unusual grinding or loud hum.

Check under the sink for leaks and secure any loose drain connections.

Costs and replacement parts, what to expect

Replacement filter assemblies generally cost about $10 to $60.

OEM parts sit at the higher end of that range.

Use the Kenmore model number when ordering parts to ensure fit.

If you're unsure which part to buy, contact authorized service for part confirmation.

When to call a technician versus DIY

Call a technician if the filter is fused after warm water and towel torque.

Also call if grinding continues after cleaning or if you find broken glass in the sump.

DIY if the mesh is dirty, tabs are intact, and removal was straightforward.

If warranty questions exist, contact authorized Kenmore service before major repairs to protect coverage.

Frequently Asked Questions

How often should I clean the filter on this Kenmore model?

For average use, check the filter weekly for visible debris and remove large scraps after cycles.

Fully remove and scrub the filter monthly, especially if you skip pre-rinsing.

In hard-water areas clean the mesh every two weeks to prevent mineral buildup and maintain spray pressure.

What do I do if the filter is stuck and will not turn?

Start by pouring warm tap water into the sump, wait five minutes, then try again.

Wrap the cap with a towel and use rubber gloves for more grip while twisting.

If it still will not move, stop to avoid breaking tabs, and contact authorized Kenmore service for safe extraction.

Can I use bleach or harsh chemicals to remove smells?

No, bleach and strong drain cleaners can damage plastic and mesh.

Use mild dish soap for grease and a 1 to 1 warm water and white vinegar soak for mineral scale.

After cleaning run a hot rinse cycle with one cup of vinegar on the top rack to neutralize odors.

How do I know if the filter needs replacing rather than cleaning?

Replace the filter if the mesh has visible holes, if tabs or the cap are cracked, or if the plastic is warped.

A torn screen lets grit pass to the pump and raises failure risk.

Order the specific assembly for your Kenmore model to ensure proper fit.

Will running the dishwasher without the filter damage the machine?

Yes, operating without the filter risks allowing debris into the pump and can cause clogging and damage.

The filter protects the impeller and improves cleaning, so never run long cycles without it in place.

If you cannot re-seat the filter, stop and call service before running the dishwasher.
