How to Clean Your Dishwasher Filter the Right Way

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.

Cleaning a dishwasher filter can be frustrating, especially when it interrupts a normal household routine. A symptom alone does not identify a failed part, so start with observations that are safe, repeatable, and useful if you later arrange a Kenmore service visit.

This guide separates routine care from work that requires testing or disassembly. Do not bypass a lock, safety switch, or error message to keep an appliance running. Taking a few notes now can make the eventual diagnosis faster and more accurate.

Start with the simple conditions

Wait until the dishwasher is off and cool, then use the manual to locate, twist, and lift the filter only as instructed. Make the check with the appliance in its normal position and without forcing panels, fittings, or controls. If the result changes after a simple adjustment, run one normal cycle or operation before drawing a conclusion.

Food debris in the mesh or filter housing can reduce cleaning and drainage, particularly in homes that do not pre-rinse dishes. Look for a pattern: whether the issue happens every time, only with a particular load or setting, or after the appliance has been running for a while. That distinction is more valuable than repeatedly restarting the appliance. Rinsing the filter in a sink of running water rather than scraping it with a tool keeps the fine mesh from being damaged.

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.

1. Turn the filter assembly counterclockwise and lift it out.
2. Lift slightly and pull forward on the stainless steel filter to separate it.
3. Clean both parts with a soft brush under running water.
4. 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

Consult the use-and-care manual for model-specific controls, filter access, and maintenance intervals. Clean only parts described as user-serviceable, use the recommended cleaning products, and refit every removable part exactly as it was designed to sit.

Before trying another cycle, clear obstructions, reduce an unusually heavy load, and make sure airflow, water supply, or door clearance is not being restricted. Avoid repeated resets: they can hide an intermittent fault and may leave water, heat, or pressure where it should not be.

• Record any displayed message or error code before clearing it.
• Check visible hoses, vents, seals, and plugs without moving electrical connections.
• Use one controlled test rather than several back-to-back attempts.
• Refit the filter assembly until it clicks before starting any cycle.
• Handle the stainless steel filter carefully because of its sharp edges.

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

If the basic checks do not change the symptom, stop at the user-serviceable boundary. Internal wiring, heating circuits, pumps, motors, refrigerant lines, gas connections, and control boards need the correct test equipment and a technician who can verify the repair safely.

Arrange service promptly when performance is getting worse, the appliance trips a breaker, leaks near electrical parts, smells hot or burnt, makes a new grinding noise, or cannot complete a normal cycle. Do not continue operating an appliance that gives a safety warning.

What to tell the technician

Share the model number, the exact symptom, when it began, what settings were selected, and the results of the safe checks above. A photo of a code or a short description of the sound can also help, but never remove a cover to obtain it.

Careful observation is not a substitute for repair, but it is the best first step. Address the simple conditions, preserve any useful error information, and leave electrical, gas, sealed-system, and internal mechanical work 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.

Official manuals and support notes are available on Kenmore Support.

Write down the full model number before ordering parts. Board and sensor revisions can change which part number is correct.

A single power reset can clear a temporary fault, but repeated returns of the same code usually mean a physical cause remains.

Keep vents and filters clear between visits. Restricted airflow often mimics electrical or sensor failures.

If water, burning smells, or sparking are present, stop using the appliance and arrange a professional inspection.
