Before You Start

Ensure the dishwasher is cool to touch and powered off. Unplug the unit or switch off the circuit breaker if accessible. Remove the bottom rack to access the sump and filter cleanout. Do not use metal tools that could scratch surfaces. Avoid mixing cleaners with bleach or ammonia, and never use pressurized sprays inside the dishwasher.

Time estimate: about 45–60 minutes for a thorough clean, plus additional time for drying. If the dishwasher is heavily soiled, plan for two sessions.

Step-By-Step: How To Clean A Kenmore Dishwasher

Power down and access the interior by removing racks. Inspect the door seal for grime and wipe it clean with a damp cloth.
Remove and inspect the bottom filter assembly. Use the dishwasher cleaning brush for filter to scrub away stuck debris and rinse thoroughly.
Use the stainless steel dishwasher cleaning brush to gently scrub the interior walls and corners, paying attention to the sump and spray arms.
Check the spray arms for clogs. If needed, remove them according to the user manual and rinse under running water, clearing holes with a brush or a pin.
Inspect the drain area for visible blockages. If drainage is slow, use the drain clog remover tool kit for dishwasher to dislodge hair, food, or mineral buildup.
Wipe down the door interior and gaskets with a damp cloth to remove residue. Leave the door ajar for a few minutes to air dry.
Run a test cycle empty with a dishwasher-safe cleaner or a cup of white vinegar placed in the upper rack. This helps dissolve mineral deposits and odors.
After the cycle completes, inspect the filter and drain again for any remaining debris. Rerun a short rinse if needed.
Reassemble the racks and run a quick wash with no dishes to ensure everything functions smoothly.
Schedule routine cleaning every 1–3 months depending on usage, and after heavy use or post-holiday meals, for best results.

Troubleshooting

Symptom	Likely Cause	Fix	Prevention
Dishwasher smells	Odor buildup in filter or sump	Clean filter and interior thoroughly	Regular cleaning every 1–3 months

Common Mistakes

Using harsh chemicals that damage gaskets or coatings

Ignoring clogged spray arms or filters during routine maintenance

Tips For Best Results

Run an empty cycle with a dishwasher-safe cleaner monthly to prevent mineral buildup.
Use vinegar sparingly; frequent use can raise acidity and affect rubber seals over time.
Always check the drain filter after heavy use to avoid drainage issues.
Keep the door seal clean to improve sealing and odor control.

Call A Professional

Seek professional help if the dishwasher shows persistent drainage problems, gas-like smells, electrical burning odors, or cycles that won’t complete despite cleaning. Signs to stop DIY attempts include exposed wiring, visible damage to the door, or malfunctioning control panel.

FAQ

Can I use bleach to clean my Kenmore dishwasher?

Bleach can damage rubber seals over time; use it sparingly and follow manufacturer guidance. A dishwasher-safe cleaner or vinegar-based method is typically sufficient for routine cleaning.

How often should I clean the filter?

Check and clean the filter every 1–2 months, or more often if the appliance handles heavy loads or shows drainage issues.

Why are my dishes still dirty after a cycle?

Likely causes include a clogged spray arm, a full or clogged filter, or insufficient detergent. Clean the filter, arms, and run an empty cycle with a cleaner.

Is it safe to remove spray arms for cleaning?

Yes, but consult the Kenmore manual for model-specific guidance. Ensure arms are securely reattached after cleaning.

What should I do about hard water buildup?

Use a mineral- or scale-removing cleaner designed for dishwashers and consider a water softener if mineral buildup persists.
