Cleaning a Kenmore dishwasher regularly helps maintain cleaning power, prevent odors, and extend the appliance’s life. This guide provides practical, step-by-step instructions and the right tools to use, with a focus on American kitchens and typical household setups.
Following a simple routine can keep interior racks, spray arms, filters, and seals in top shape. The steps below use common household cleaners and tools designed for dishwashers, including specifically chosen items from a care kit and brushes that target interior components.
Quick Answer
Flush and clean the interior, clear the spray arms, and remove the filter. Use a descaler tablet or cleaner cycle to dissolve mineral buildup, then rinse with a hot wash. Do this every 1–3 months depending on water hardness and usage.
What You’ll Need
- Dishwasher cleaning brush for interior and filter
- Dishwasher spray arm cleaning brush
- Dishwasher filter cleaning tool kit
- Dishwasher descaler tablet for automatic cleaning
- Kenmore dishwasher maintenance kit
Before You Start
Ensure the dishwasher is cool before you begin and that the door is unlocked. Remove standing water if present and clear large food particles from the bottom. Run a quick empty cycle with a rinse aid to inspect seals and forego harsh cleaners on stainless steel surfaces. Safety note: unplug the unit or switch off the circuit breaker before taking apart any interior components. Allow a short ventilation period after removing the kick panel or access door to avoid moisture buildup.
Step-By-Step: How To Clean A Kenmore Dishwasher
- Open the door and remove all racks. Use a flashlight to inspect the interior walls and corners for debris.
- Wash the interior with a dishwasher cleaning brush for interior and filter to dislodge stuck food and mineral buildup around the tub edges.
- Inspect the filter system. Remove the filter and rinse it under warm water. Use the dishwasher filter cleaning tool kit to scrub the mesh and the housing as needed.
- Clean the spray arms. Detach spray arms following the manual, then scrub the jets with the dishwasher spray arm cleaning brush to remove clogs.
- Run a preliminary hot rinse cycle to dislodge loosened particles from the tub and filters.
- Apply a dishwasher descaler tablet for automatic cleaning or run a dedicated cleaner cycle per the product directions to dissolve mineral deposits.
- Return racks and run a full hot cycle with clean water. If your model supports it, select a high-temperature rinse to maximize residue removal.
- Inspect seals and door gaskets. Wipe with a damp cloth and a mild detergent, ensuring there are no cracks or wear that could leak.
- Wipe the exterior of the door and control panel. Dry panels to prevent streaks and fingerprint marks.
- With the unit still empty, run a final hot cycle to flush out any remaining cleaner residue.
- Document maintenance tasks and schedule the next cleaning based on water hardness and dishwasher usage.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Dishwasher not cleaning properly | Clogged spray arms or filter | Clean spray arms and filter with the appropriate brushes and kit | Regular maintenance schedule |
| Weird odor after cycles | Food residue in filter or seal area | Deep clean interior and replace or clean seals | Remove debris after each cycle |
| Water pooling at bottom | Door gasket leak or clogged drainage | Check gasket and drain for blockages; clear with tool kit | Inspect gasket every few months |
| Mineral buildup around jets | Hard water deposits | Use descaler tablet and run an empty cycle | Use rinse aid and consider water softener if available |
Common Mistakes
- Using abrasive cleaners that scratch stainless steel or plastic parts
- Neglecting the filter and spray arm maintenance
- Running wrong cycle temperatures or skipping descale steps in hard water areas
- Forgetting to remove large food particles before loading
Tips For Best Results
- Schedule a monthly clean when water is hard, or every 1–3 months with softer water.
- Use a dishwasher descaler tablet specifically designed for automatic cleaning cycles.
- Keep the spray arm nozzles clear by inspecting and brushing out clogs after heavy use periods.
- Run hot cycles with empty loads to maximize residue removal and sanitize surfaces.
- Maintain a routine that includes checking seals and gaskets for wear and replacing when necessary.
Call A Professional
Consider a professional if the dishwasher shows persistent leaks, unusual noises during operation, or failing to complete cycles despite cleaning. Signed issues include:
- Chronic leakage from door or seals
- Repeated cycling error codes after cleaning
- Electrical smells or unusual burning after cycles
These signs may indicate internal component wear, wiring problems, or control board issues that require certified service.

Buying Guide
When choosing gear to simplify cleaning a Kenmore dishwasher, consider size of brushes, compatibility with filters, and materials that resist heat and moisture. Key buying factors include:
- Size and head design of brushes for interior, filter, and spray arms
- Material durability and compatibility with stainless steel and plastic
- Effectiveness of descaler tablets for automatic cleaning

Is a full maintenance kit worth it? For many owners, a kit consolidates tools and cleaners into one package, simplifying routine care. Look for a kit that includes a filter cleaning tool, spray arm brushes, and a descaler tablet, alongside model-specific guidance. If your Kenmore has unique features or a taller interior, verify tool compatibility before purchasing. A well-chosen kit can make regular maintenance quick, predictable, and more effective. If unsure, consult the product manuals and consider professional guidance for initial setup.
