Maintaining the filter in a Kenmore dishwasher helps improve cleaning performance and extend the appliance’s life. Built-up debris can reduce water flow, cause clogs, and leave dishes dirty. This guide provides practical steps to refresh an aging filter, using common tools and a dedicated cleaning kit.
Progressively cleaning an old filter requires care to avoid damaging screens or seals. The method below focuses on safety, efficiency, and thorough removal of trapped food particles, grease, and mineral deposits.
Quick Answer
Remove the filter, rinse under warm water, scrub with a Kenmore dishwasher filter cleaning brush, and dry before reassembling. If debris remains, use a dishwasher filter cleaning kit or a dishwasher debris screen cleaning brush to reach tight spaces. Regular maintenance with a dishwasher filter maintenance kit helps prevent buildup.
What You’ll Need
- Kenmore dishwasher filter cleaning brush
- Dishwasher filter cleaning kit
- Dishwasher debris screen cleaning brush
- Dishwasher screen filter cleaning brush
- Dishwasher filter maintenance kit
Before You Start
Disconnect the dishwasher from power or ensure the control is off to prevent accidental operation. Gather all tools at hand and clear the area around the dishwasher. Remove the lower rack to access the filter assembly easily. Expect a brief cleanup time, typically 15–30 minutes depending on buildup. Take care not to damage seals or gaskets while disassembling and reassembling components. If the dishwasher is extremely old or shows persistent leaks, consider professional service.
Step-By-Step: How To Clean Old Kenmore Dishwasher Filter
- Open the dishwasher door and remove the lower rack to reveal the filter assembly.
- Take out the filter and debris screen according to the model’s manual or by gently twisting counterclockwise.
- Rinse the filter under warm running water to loosen loose food particles.
- Use the Kenmore dishwasher filter cleaning brush to scrub the mesh and plastic parts, paying attention to crevices where grime accumulates.
- If buildup remains, scrub with the dishwasher debris screen cleaning brush and dishwasher screen filter cleaning brush to access narrow channels.
- Inspect for tears or damaged seals. If the screen is cracked, replace it with a compatible part from a dishwasher filter maintenance kit.
- Rinse again to remove any loosened particles. Use a gentle spray to avoid warping the screen.
- Let the filter dry completely before reinstalling. Reassemble the filter and debris screen in the correct orientation.
- Run a short empty wash with a brief rinse cycle to ensure proper water flow and check for leaks or unusual noises.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Dishes come out dirty | Clogged filter or spray arms | Deep clean the filter with brushes; inspect and clean spray arms | Clean on a regular schedule |
| Water drains slowly | Debris buildup in filter or sump | Remove and clean sump and filter components | Run periodic cleaning cycles |
| Unpleasant odors | Residual food in filter | Thorough cleaning; wipe interior surfaces | Run hot cycles after meals |
| Leaking around door | Seals worn or misaligned during reassembly | Check gasket seating, reseat or replace | Handle components gently during maintenance |
| Filter frame cracked | Age and wear | Replace with compatible filter kit | Inspect at each cleaning |
Common Mistakes
- Using abrasive tools on mesh screens, which can tear the filter.
- Skipping drying before reassembly, which can trap moisture and promote mold.
- Forcing the filter back into place when misaligned.
- Ignoring model-specific instructions, since Kenmore units vary by generation.
Tips For Best Results
- Clean the filter every 1–3 months, depending on usage and water hardness.
- Use a soft brush and warm water; avoid strong chemical cleaners that may degrade plastic.
- Keep the debris screen dry before reinstalling to help fit properly.
- Label and store replacement parts from the dishwasher filter maintenance kit for quick future servicing.
Call A Professional
Stop and call a professional if any of the following occur: persistent leaks after reassembly, cracks in the filter housing, inconsistent water flow after cleaning, or if the dishwasher fails to start due to electrical issues. Do not attempt to bypass safety features or bypass moisture-related alarms.

Buying Guide
When selecting replacement parts or tools for a Kenmore filter, consider size compatibility, filter mesh density, and kit completeness. A comprehensive dishwasher filter maintenance kit often includes multiple brushes designed for various mesh sizes and tight spaces, improving long-term maintenance. Think about noise tolerance and energy usage, as a clean filter supports efficient water flow and reduces cycle time. For placement, ensure the kit includes guidance or parts suited to your specific Kenmore generation. If replacing screens, verify that the replacement screen aligns with the existing frame and seals to prevent leaks. In short, choose a kit that matches your model, includes multiple cleaning tools, and offers clear installation instructions to maximize longevity and performance.
