Before You Start

Step-By-Step: LG Dishwasher Filter Cleaning
- Open the dishwasher and remove the lower rack to access the filter assembly.
- Locate the filter in the sump area and gently lift or unlock it according to the model’s design.
- Pull the filter out and inspect for debris, standing water, or clogs that restrict water flow.
- Rinse the filter under warm running water to remove loose debris. Use a LG dishwasher filter cleaning brush to agitate stuck material.
- For stubborn buildup, soak the filter in warm, soapy water for 5–10 minutes before scrubbing with a dishwasher filter brush long handle.
- Use a dishwasher maintenance tool kit spray nozzle to rinse crevices and the sides of the filter housing.
- Dry the filter completely with a clean towel, then reinstall it securely in the sump.
- Reconnect the lower rack, run a rinse cycle with no dishes to clear any remaining debris, and inspect drainage afterward.
- If a replacement is needed, install the LG dishwasher filter replacement part following manufacturer guidelines.
- Repeat the process every 1–3 months, or sooner with heavy use or hard water concerns.
- For best results, combine regular cleaning with routine external wipe-downs of the door gasket and interior walls.
- Record maintenance notes to track when the next cleaning is due and whether parts were replaced.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Dishwasher not draining well | Clogged filter or sump | Clean filter thoroughly and inspect spray arms | Regular cleanings; avoid large food scraps |
| Residue on dishes | Filter not sealing properly | Reinstall filter correctly; check for cracks | Inspect during every cleaning |
| Unpleasant odor | Residual food buildup | Soak and scrub more thoroughly; run a hot-water wash | Frequent quick cleans |
| Water left in bottom after cycle | Clogged filter/air gap | Remove and clean filter; check drain hose | Keep filter clean; avoid overloading |
Common Mistakes
- Using harsh chemicals that could corrode the filter or seals
- Rushing the drying step and reinstalling a damp filter
- Forgetting to inspect the filter housing for cracks or damage
- Neglecting routine maintenance and waiting until drainage issues appear
Approach cleaning with a steady hand and follow model-specific guidance when available. A thorough, calm approach reduces the risk of damage and improves results.
Tips For Best Results
- Use warm water and a mild detergent for best debris removal.
- Keep a small cleaning kit handy in the laundry area for quick maintenance sessions.
- Consider a long-handle brush to reach tight spaces without bending awkwardly.
- If mineral buildup is common, run a descaling cycle periodically according to LG recommendations.
- Document the date of cleaning and any part replacements to anticipate future needs.
