What You’ll Need

Before You Start
Before beginning, remove all dishes and rinse debris from racks. Ensure the dishwasher is cool and unplugged if accessible, or set to a non-powered mode as a precaution. Use gloves to protect hands from any cleaners. Time estimate: 45–60 minutes for a full cleaning and inspection.
Caution: Do not mix cleaners unless the product instructions explicitly allow it. Avoid using abrasive brushes that can scratch the tub or spray arms. If the appliance has signs of leaks or electrical concerns, discontinue use and seek service.
Step-By-Step: How To Clean LG Dishwasher
- Empty the dishwasher and remove racks to access the tub walls and spray arms.
- Run a hot water wash to loosen any loose debris, then add an automatic dishwasher cleaner for LG into the detergent dispenser or as directed by the product label.
- Run an empty cycle on a hot setting to dissolve grease and mineral buildup. Stop the cycle if possible and inspect the interior.
- Use the dishwasher spray arm cleaning brush to scrub around the spray arms and jets, removing any clogs or mineral deposits.
- Wipe the tub walls with a damp cloth or a tub cleaning powder kit as recommended by the cleaner’s instructions.
- Place a tablet from LG dishwasher cleaner tablets or a compatible powder kit inside the専detergent compartment and run another hot cycle to rinse residue.
- Reinstall racks and run a final rinse to ensure all cleaner residues are flushed out.
- Inspect door seals and interior corners for mold or mildew and wipe with a mild cleaner if needed.
- Test with a small load to verify improved cleaning and drying performance.
- schedule routine maintenance every 1–3 months depending on usage and water hardness.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Odor after cycles | Stale water or trapped debris | Clean tub and spray arms; run an empty cycle with cleaner | Regular monthly cleanings |
| Poor drainage | Clogged filter or hose | Inspect and clean filters; verify hose clearance | Check filters every 1–2 months |
| Residue on dishes | Overuse of cleaner or soft water mineral buildup | Use appropriate amount of cleaner and run hot cycle | Space out heavy clean cycles; consider water softener |
| Spray arm won’t spin | Blockage in arm jets | Clean jets with brush; remove debris | Rinse after heavy cooking junk |
Common Mistakes
- Overloading the dishwasher during cleaning cycles, which blocks spray arms.
- Using acidic cleaners on rubber seals too often, causing wear.
- Neglecting the filter and debris screen, leading to recurring clogs.
- Not running a final rinse after cleaner use, leaving residues.
Keeping to a simple routine reduces these issues and extends dishwasher life.
Tips For Best Results
- Run an empty hot cycle with cleaner every 1–3 months, depending on usage.
- Plan deep cleanings after periods of heavy use to prevent mineral buildup.
- Use recommended cleaners for LG models to avoid seal damage.
- Check door seals and gaskets during each maintenance session.
- Consider a water hardness test and adjust cleaning frequency accordingly.
Call A Professional
Contact a professional if you notice persistent leaks, a non-functional spray arm, or electrical issues beyond basic clogs and residue removal. Stop using the unit and schedule service if the dishwasher fails to complete cycles, vibrates abnormally, or emits unusual sounds during operation.

Buying Guide
Choosing the right cleaning supplies for an LG dishwasher depends on several factors. Size and capacity influence how often you need to clean and how much residue management is required. Consider noise level expectations if you run cycles at night and want minimal disruption. Energy efficiency remains important, so opt for cleaners and routines that minimize energy use by avoiding prolonged cycles. Look for cleaners with clear instructions for LG models and verify compatibility with your dishwasher’s model year. Controls should be straightforward to use, with easily accessible dispensers and clear cycle indicators. Placement matters too—store cleaners in a cool, dry area away from direct heat and moisture, but within easy reach of the kitchen. When comparing products, weigh the benefits of all-in-one tub cleaners against targeted tools like spray arm brushes and dedicated tablets, and choose a kit that covers both routine maintenance and deeper cleanings for ongoing performance. Would you benefit from a single kit that combines tablets, a tub cleaner, and a spray arm brush for convenience? A balanced approach often yields the best long-term results.
