To clean a Kenmore dishwasher filter, turn the filter assembly counterclockwise, lift it out, brush it gently under running water, and refit it until it clicks before the next cycle. On many Kenmore models that takes only a few minutes, and a dirty filter can cause odor, grit on dishes, and drainage problems.
A dishwasher filter that needs attention can disturb the usual household routine. Nothing about a symptom tells you a part has failed, so start with safe, repeatable observations that would help a later Kenmore service visit.
Routine care and work that calls for testing or disassembly are separate matters. A lock, safety switch or error message should never be bypassed to keep a dishwasher running, and a few notes taken now can sharpen and speed up any diagnosis later.
Start with the simple conditions
Let the dishwasher sit off until it has cooled, then follow the manual to find the filter, twist it and lift it out exactly as directed. Leave the machine in its normal position and do not force panels, fittings or controls. Should a small adjustment make a difference, run one regular cycle before reaching a verdict.
Debris caught in the mesh or the filter housing can hurt both cleaning and drainage, and more so in households that skip pre-rinsing. Notice the pattern: each cycle, certain loads or settings only, or after the machine has run a while. That detail beats starting the cycle again and again. Holding the filter under running water at the sink, instead of scraping at it with a tool, protects the fine mesh.
| Job | Timing | Technique |
|---|---|---|
| Flush the filter | Every month | Use warm water |
| Remove stuck debris | When needed | Soft brush |
| Inspect the housing | At each clean | Gentle wipe |
What is the removal and rinse sequence?
Turn the filter assembly counterclockwise, lift it out, brush it gently under running water, and refit it until it clicks.
The guide for one Kenmore dishwasher describes the steps in order.
- Turn the filter assembly counterclockwise and lift it out.
- Lift slightly and pull forward on the stainless steel filter to separate it.
- Clean both parts with a soft brush under running water.
- Fit the parts back into the holder and turn the inner filter until it clicks.
The stainless filter can have sharp edges, so handle it with care. Your own manual shows the exact sequence for your model.
Safe checks that protect the appliance
For anything specific to your model, such as controls, filter access or maintenance timing, turn to the use-and-care manual. Clean only what it labels user-serviceable, stay with the cleaning products it recommends, and return every removable part to its designed seat.
Next time around, clear out obstructions, scale back an unusually full load, and check that nothing restricts airflow, the water supply or door clearance. Repeated resets deserve caution too, since an intermittent fault can hide behind them and water, heat or pressure may end up somewhere unsafe.
- Note any displayed message or error code first, then clear it.
- Check the hoses, vents, seals and plugs you can see, without disturbing electrical connections.
- Run one deliberate test, not several in a row.
- Fit the filter assembly back until it clicks before any cycle starts.
- Take care with the stainless steel filter, whose edges are sharp.
Things you can do
- Warm-water rinse
- Soft brush
- Seat the filter firmly
Not for owners
- Sharp tools
- Running with no filter
- Reaching into the pump area
How often is the filter due, and what does the result tell you?
The guide says the filter should be cleaned once a month for best performance, with more frequent cleaning for heavy use. Visible objects or soil on the filter, or dishes that feel gritty, signal that it is due. In hard water above 15 grains the guide says at least monthly, and a white residue on surfaces points to hard water.
A clean filter does not prove the drain path is clear. If water still stands in the tub afterward, the guide lists a kinked or clogged drain hose, and a clogged air gap or disposer, as other places to look.
Know when the symptom needs diagnosis
A symptom that outlasts the basic checks marks the edge of what an owner should handle. Anything involving control boards, heating circuits, pumps or motors, wiring inside the cabinet, gas connections or refrigerant lines calls for correct test equipment and a technician who can check the repair is safe.
Do not put off booking service when things are getting worse, a breaker trips, liquid reaches electrical parts, a burnt or hot odor appears, a grinding noise is new, or a regular cycle cannot be completed. Stop running any appliance that shows a safety warning.
What to tell the technician
Pass along the model number, exactly what is happening, the date it began, the settings in use and what the safe checks showed. If a code is on the display, a photo of it is useful, as is a brief description of any sound; no cover should ever come off to get either.
Paying attention is no replacement for a repair, though it is the soundest place to start. Take care of the simple conditions, keep any error details that might help, and give anything involving gas, electricity, the sealed system or internal mechanics to a specialist Kenmore technician.
Common questions
Can the dishwasher run without the filter?
The guide says to run it only with the filter assembled correctly, so refit it fully before every cycle.
Why do dishes feel gritty even after a cycle?
The guide gives gritty dishes as a sign the filter may need cleaning. Soil left on the filter can be washed back around the tub, so a rinse and brush is the first thing to try.
Does pre-rinsing change how often to clean the filter?
Yes. The guide’s table recommends cleaning every six months for households that wash dishes before loading, and weekly for heavy use without scraping. Match the schedule to your habits and check your own manual.

Before a part is ordered, record the full model number; revisions to boards and sensors may change the correct part number.
Resetting the power once can wipe out a temporary fault; if the same code returns again and again, a physical cause is probably still there.
Vents and filters should stay clear in the time between service calls, as restricted airflow can imitate sensor or electrical faults.
Puddles, a scorched odor or visible sparks are reasons to quit using the unit right away and hand it to a professional for inspection.
