Fast method: Run an empty cycle with a dishwasher cleaner tablet, then hand-clean the interior with a flexible brush and spray cleaner. Regular monthly maintenance prevents buildup and improves performance.
What You’ll Need
- Dishwasher cleaning brush flexible handle
- Dishwasher filter cleaning brush stainless steel bristles
- Automatic dishwasher cleaner tablets descaler
- Dishwasher rack and spray arm brush kit
- Dishwasher interior cleaner spray
Before You Start
Before beginning, unplug the dishwasher or ensure the circuit is off to avoid accidental activation. Clear the interior of all racks and utensils. If there is standing water in the bottom, sop it up with a sponge. Safety cautions include wearing gloves to protect your hands from sharp edges and following manufacturer instructions for any cleaners. Time estimates vary: plan 60 to 90 minutes for a thorough deep clean, plus a quick 15-minute monthly maintenance cycle.
Step-By-Step: How To Clean A Dishwasher
- Remove and inspect all racks and the bottom filter (if accessible). Rinse or wipe away loose debris to prevent clogs.
- Apply the dishwasher interior cleaner spray to the interior walls, door seals, and hard-to-reach areas. Let it sit for a few minutes to break down grease.
- Use the dishwasher cleaning brush flexible handle to scrub the door seal, the corners, and any stubborn buildup on the tub walls. Pay attention to gaskets where mold may gather.
- Remove the filter and clean it with the dishwasher filter cleaning brush stainless steel bristles to dislodge trapped particles. Rinse thoroughly before reinserting.
- Place a dishwasher cleaner tablet or descaler in the detergent cup or directly in the basket and run the hottest appropriate cycle with no dishes. This dissolves mineral deposits and freshens the interior.
- While the cleaning cycle runs, use the dishwasher rack and spray arm brush kit to inspect and gently scrub the spray arms’ holes and the rack components. Remove any mineral buildup that blocks spray nozzles.
- After the cycle finishes, wipe down the interior again with the interior cleaner spray to remove any remaining grime. Leave the door open briefly to air-dry and prevent musty odors.
- Reassemble racks and run a quick rinse cycle with no dishes to ensure all cleaner residues are flushed out.
- Optional: run a second gentle cycle with a small amount of white vinegar placed in a cup on the top rack for extra deodorizing, but avoid mixing vinegar with bleach or harsh chemicals.
- Establish a maintenance routine: a light wipe-down after each use and a full deep clean every 1–3 months, depending on usage and water hardness.
- For stubborn odors or mineral buildup, repeat the appropriate steps or combine the cleaner tablet method with targeted interior cleaning spray sessions.
- Inspect door seals for cracks or wear. Replace damaged gaskets to maintain a proper seal and prevent leaks.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Persistent odors | Trapped moisture and food particles | Clean seals and filter; use interior cleaner spray | Leave door ajar after cycles; run monthly |
| Water not draining | Clogged filter or spray arms | Clean filter with stainless steel bristles; check spray arms | Regularly remove debris from racks and filter |
| Streaks on dishes | Residue from hard water or detergent | Run cleaner tablet cycle; use correct detergent amount | Periodically descale with descaler products |
| Visible mineral buildup | Hard water deposits | Descale cycle and manual brushing of tub walls | Use a descaler periodically based on water hardness |
| Gasket leaks | Worn or dirty door seal | Clean with interior cleaner spray; replace if damaged | Wipe seals after each cycle |
Common Mistakes
- Using bleach-based products with ammonia cleaners can release harmful fumes.
- Overfilling the detergent dispenser with too many cleaner tablets can cause residue on dishes.
- Neglecting to clean filters and spray arms, which reduces cleaning efficiency.
- Ignoring door seals and gaskets, leading to leaks and odors.
Tips For Best Results
- Schedule a regular maintenance cycle every 1–3 months to prevent buildup.
- Use the right tools: a flexible handle brush for hard-to-reach areas and a stainless steel bristle brush for filters.
- Check water hardness in your area; harder water benefits from more frequent descaling.
- Store cleaning tools in a dry, accessible location near the dishwasher for quick touch-ups.
- Consider a dedicated interior cleaner spray for fast wipe-downs between deep cleans.
