Keeping a dishwasher clean helps it run efficiently, prevent odors, and extend its lifespan. This guide walks American homeowners through a straightforward, step-by-step process using common dishwasher cleaning tools designed to tackle every interior and hard-to-reach area.
Quick Answer
For a quick clean, run an empty cycle with a dishwasher-safe cleaning product, then perform a targeted interior scrub using a dishwasher interior cleaning microfiber sponge and specialty brushes to remove buildup from gaskets, filters, and spray arms.
What You’ll Need
- Dishwasher gasket cleaning brush
- Dishwasher filter cleaning brush
- Dishwasher spray arm cleaning tool
- Dishwasher sump cleaning brush
- Dishwasher interior cleaning microfiber sponge
Before You Start
Prepare the area around the dishwasher and ensure the appliance is cool before handling interior components. Remove any dishes from the dishwasher and unplug the unit or switch off the circuit breaker for safety. Avoid using bleach and ammonia together, and never mix harsh chemicals with the dishwasher’s internal components. Estimate 30–60 minutes for a thorough cleaning. If the dishwasher drains slowly or emits strong odors, allow extra time for deeper cleaning and drying between steps.
Step-By-Step: How To Keep Your Dishwasher Clean
- Open the dishwasher and remove racks to access the sump and filter areas.
- Inspect the gasket for debris, then use the gasket cleaning brush to scrub along the door seal and corners.
- Remove the filter assembly and rinse it under warm water; use the dishwasher filter cleaning brush to scrub stubborn buildup from the screen.
- Clear the spray arms by removing any obstructed nozzles and using the spray arm cleaning tool to dislodge trapped debris.
- Clean the sump area with the sump cleaning brush to remove dark residue and mineral deposits.
- Wipe the interior walls with the microfiber sponge, focusing on corners where grime accumulates; rinse the sponge frequently.
- Run a hot empty cycle with a dishwasher-safe cleaner or a cup of white vinegar placed on the top rack to dissolve remaining grease.
- Inspect door seals again after the cycle and wipe away any loosened debris with the gasket brush.
- Reassemble racks and run a short rinse cycle to ensure all cleaning agents are flushed out.
- Leave the door ajar for a short period after cleaning to air-dry, reducing musty odors.
- Establish a routine: repeat monthly or quarterly depending on usage and water quality.
- Address persistent odors by checking for hidden mold in crevices and ensuring proper drainage.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Unpleasant odor after cleaning | Residual food particles and stagnant water | Thoroughly clean sump and filter; run empty cycle with cleaner | Regular weekly wipe-downs of interior surfaces |
| Spray arms not rotating | Clogged nozzles | Use spray arm cleaning tool to dislodge debris | Avoid overloading; rinse dishes before loading |
| Water not draining | Blocked pump or filter | Clean filter and sump; inspect drain hose for kinks | Inspect and clean monthly |
| Gasket leaks | Worn or dirty door seal | Clean gasket with brush; replace if cracked | Wipe seal after each cycle to prevent buildup |
Common Mistakes
- Using abrasive scrubbers on metal surfaces which can scratch and harbor bacteria.
- Avoiding the interior entirely and relying only on external cleaning.
- Overfilling the dishwasher with detergent or using incompatible cleaners.
- Ignoring odors that indicate hidden mold or standing water issues.
Regular maintenance reduces buildup and helps prevent costly repairs over time.
Tips For Best Results
- Schedule a monthly interior clean and a quarterly deep clean for high-use households.
- Pre-rinse dishes lightly to reduce particle buildup inside filters and spray arms.
- Rotate or replace worn gaskets and seals as needed to maintain a tight door seal.
- Use dishwasher detergents designed for your water hardness to minimize mineral deposits.
- Keep the door open after cleaning to improve air circulation and drying.
Call A Professional
Seek professional help if signs of leaks persist after cleaning, if the dishwasher fails to drain despite routine maintenance, or if there are electrical smells or humming noises during operation. Do not attempt to repair electrical components beyond basic troubleshooting.

For persistent drainage or electrical issues, professional service ensures safety and proper repairs.
Buying Guide
When evaluating cleaning tools and accessories for a dishwasher, consider how they fit your routine and machine. The following factors help ensure you choose effective, compatible items.
- Size and compatibility: Tools should fit typical American dishwasher interiors; ensure brushes reach the sump and hard-to-reach corners.
- Effectiveness for different buildup: Gasket, filter, and spray arm tools target common problem areas and prevent odor formation.
- Durability and material: Look for sturdy bristles and non-scratch materials to avoid damage to interior surfaces.
- Ease of use: Ergonomic handles and tool shapes that allow single-handed operation improve cleaning efficiency.
- Maintenance frequency: A basic set supports regular upkeep; add more specialized tools if you experience frequent clogs or mineral buildup.
- Noise and energy considerations: Cleaning cycles are separate from daily use; focus on tools that reduce recurring issues to keep performance steady.
- Placement and storage: Compact tool sets store conveniently near the dishwasher for quick access during routine maintenance.
