New dishwashers can emit temporary odors as seals and hoses release factory scents and manufacturing residues. A fresh, clean dishwasher not only smells better but also helps maintain hygiene and performance. This guide provides practical steps, safe cleaners, and simple tools to neutralize smells quickly and effectively.
Quick Answer
Run an empty cycle with hot water and a dishwasher-safe cleaner, then inspect the gasket and filter for debris. If odors persist, use a non-abrasive cleaner on the tub and a deodorizing tablet kit as directed. Regular maintenance prevents future smells.
What You’ll Need
- Dishwasher cleaning brush with long handle
- Dishwasher deodorizing cleaner tablets kit
- Gasket scrubber silicone dishwasher filter brush
- Non-abrasive dishwasher tub cleaner spray bottle
- Drain cleaning wand for dishwasher odor removal
Before You Start
Prep the area and ensure the dishwasher is empty. Read the user manual for any cleaning restrictions specific to your model. Use safety gear as needed, especially when handling chemicals. Avoid mixing cleaners and never use chlorine bleach with ammonia-based products. Plan for a 60–90 minute cleaning window, depending on odor severity.
Step-By-Step: How To Get Rid Of New Dishwasher Smell
- Run a hot water cycle with no dishes to flush residues from the interior.
- Inspect the filter and drain area; remove visible debris using a drain cleaning wand for dishwasher odor removal.
- Gently scrub the door gasket with a gasket scrubber silicone dishwasher filter brush and warm foamy water to lift trapped particles.
- Wipe the tub surfaces with a non-abrasive dishwasher tub cleaner spray bottle to remove film.
- Place a dishwasher deodorizing cleaner tablet kit in the detergent dispenser or run a dedicated cleaning cycle per product instructions.
- For stubborn smells, run another hot cycle with the cleaner only and no dishes; allow the cycle to complete fully.
- Check spray arms and inlet screens; remove any buildup using the long-handle brush for thorough cleaning.
- Rinse the interior by running a fresh hot cycle with plain water to remove cleaning residues.
- Air out the door between cycles and keep the dishwasher door ajar after cleaning to reduce lingering odors.
- Schedule regular maintenance: monthly cleanings with the specified products to prevent recurrence.
- Store and organize future supplies in a dry place to avoid contamination and odors from stored cleaners.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Persistent odor after cleaning | Residual film or mold in gasket or tub | Deep clean with non-abrasive tub cleaner; inspect and scrub gasket | Regular quick cleanings after heavy use |
| Musty smell returns within days | Moisture stagnation in filter area | Dry interior after cycles; ensure door seal fully closes | Leave door slightly ajar post-cycle |
| Odor with water odor notes | Drain line buildup | Use drain cleaning wand to clear line | Periodic drain maintenance |
| Unpleasant chemical scent | Harsh cleaner residues | Rinse with plain hot water cycle | Follow cleaner directions precisely |
Common Mistakes
- Using abrasive brushes or scrubbers on the tub, which can scratch surfaces.
- Overusing powerful cleaners that leave strong chemical odors.
- Neglecting the drain and filter area, allowing buildup to persist.
- Ignoring manufacturer instructions for cleaning cycles and products.
Sticking to gentler tools and following cycle directions helps preserve the appliance while eliminating odors.
Tips For Best Results
- Use the dishwasher deodorizing cleaner tablets kit as part of a monthly maintenance routine for best ongoing odor control.
- Avoid mixing different cleaners; that can cause harmful fumes or residue.
- Regularly inspect the gasket and replace worn seals to prevent moisture buildup.
- Keep the dishwasher door slightly open after cycles during the first 24–48 hours post-cleaning to vent moisture.
Call A Professional
If odors persist after multiple cleanings or you notice leaks, unusual noises, or water pooling, contact a qualified appliance technician. Immediate professional help is advised for any signs of mold growth, damaged seals, or electrical concerns.

Buying Guide
When selecting products to address dishwasher odors, consider efficiency, safety, and compatibility with your unit. Key buying factors include size and coverage of cleaning tools, noise-free operation for any attachments, energy-efficient cleaning cycles, and user-friendly controls. Look for non-abrasive formulas suitable for interior tub materials and gasket materials. Consider a kit that includes both a long-handle brush for hard-to-reach areas and a tub cleaner spray for spot cleaning. Assess placement options in the laundry area to avoid spillover and store cleaners in a cool, dry place. Compare products by whether they include a drain wand, gasket brush, or deodorizing tablets, and read user reviews for real-world efficacy. A balanced kit typically offers a combination of cleaning tools and deodorizing tablets to cover routine maintenance and odor removal without harsh chemicals.
