Why Does My Dishwasher Smell?
Before diving into solutions, it’s worth understanding the root causes of dishwasher odors. According to the experts at Whirlpool, “Odors that emanate from a dishwasher are commonly caused by food debris that builds up over time—particularly if dishes aren’t pre-rinsed before loading.” This debris can get trapped in filters, spray arms, or crevices, creating a breeding ground for bacteria and mold [((Whirlpool))]. Other culprits include hard water deposits, grease buildup, or even a clogged drain hose. Identifying the source can help you target your cleaning approach effectively.

Step-by-Step Methods to Remove Dishwasher Smell
1. Clean the Filter and Interior
Most dishwashers have a removable filter at the bottom where food particles tend to collect. Start here, as it’s often the stinkiest spot. Good Housekeeping advises, “Remove the filter (check your manual if you’re unsure how), rinse it under warm water, and scrub gently with a soft brush and dish soap to dislodge trapped debris.” Afterward, wipe down the interior—door, racks, and walls—with a damp cloth and a mild detergent to remove grease or residue buildup [((Good Housekeeping))].
2. Run a Vinegar Cycle
Vinegar is a natural deodorizer and descaler, making it a go-to solution for dishwasher odors. The Spruce recommends this method: “Place a dishwasher-safe bowl filled with 1-2 cups of white vinegar on the top rack. Run a hot water cycle (no dishes, just the vinegar). The acidity breaks down grease and neutralizes smells.” For stubborn odors, you can repeat this process monthly as maintenance [((The Spruce))].
3. Use Baking Soda for Extra Odor Absorption
After the vinegar cycle, baking soda can tackle any lingering mustiness. Bob Vila’s team suggests sprinkling “about one cup of baking soda across the bottom of the dishwasher” and running a short, hot cycle. “The baking soda will absorb odors and leave the dishwasher smelling neutral,” they note. This duo—vinegar followed by baking soda—creates a powerful one-two punch against smells.
4. Inspect and Clean the Drain Hose
Sometimes the odor source isn’t inside the dishwasher but in the drain hose. “A kink or clog in the hose can trap water and food particles, leading to a foul smell,” explains Angie’s List. Disconnect the hose (turn off the power and water supply first), check for blockages, and flush it with warm, soapy water. Reattach securely once clean.
5. Tackle Hard Water or Mineral Buildup
If you live in an area with hard water, limescale can contribute to odors by trapping grime. Consumer Reports recommends using a dishwasher cleaner like Affresh or a citric acid-based product. “Fill the detergent dispenser with the cleaner and run a full cycle,” they advise. This not only removes buildup but also freshens the machine [((Consumer Reports))].

Additional Tips to Enhance Your Cleaning Efforts
Pre-Rinse Dishes (Sometimes)
While modern dishwashers are designed to handle dirty dishes, a quick rinse can prevent food from festering. CNET cautions, “Don’t overdo it—scraping off chunks is enough; a full wash defeats the dishwasher’s purpose.” Balance convenience with cleanliness to avoid odor buildup.
Leave the Door Ajar
Moisture is a mold magnet. As Maytag suggests, “After a cycle, leave the door slightly open to let air circulate and dry out the interior.” This simple habit can significantly reduce mildew smells over time.
Try Lemon for a Fresh Scent
For a natural fragrance boost, toss a halved lemon into the utensil basket during a cycle. “The citrus oils cut through grease and leave a clean scent,” says Real Simple. It’s an easy, chemical-free way to elevate your dishwasher’s freshness.

Preventing Future Dishwasher Smells
Prevention is easier than a deep clean. Here’s how to keep odors at bay:
- Run Regular Cleaning Cycles: Once a month, use vinegar or a commercial cleaner to maintain freshness.
- Check the Spray Arms: Ensure the holes aren’t clogged—use a toothpick to clear them if needed.
- Use the Right Detergent: Low-quality detergents can leave residue that smells over time. Opt for a trusted brand recommended by your dishwasher’s manufacturer.
- Run Hot Cycles: Periodically run a high-temperature cycle to kill bacteria and sanitize the interior.

Common FAQs About Dishwasher Odors
Q: How often should I clean my dishwasher to prevent smells?
A: Experts from Whirlpool recommend cleaning your dishwasher every month if you use it regularly. For lighter use, every 2-3 months should suffice.
Q: Can I use bleach to get rid of the smell?
A: Yes, but with caution. “Bleach can sanitize, but it’s harsh on rubber gaskets and stainless steel,” warns The Spruce. Use a diluted solution (1/4 cup bleach in a gallon of water) and avoid frequent use.
Q: Why does my dishwasher still smell after cleaning?
A: Check hidden spots like the drain hose, door gasket, or under the racks. Persistent odors might also indicate a plumbing issue—consider calling a professional.
Q: Are dishwasher deodorizers worth it?
A: They can mask odors temporarily, but they don’t address the root cause. Cleaning is more effective, per Consumer Reports.
Q: Can I combine vinegar and baking soda at the same time?
A: No—they neutralize each other when mixed. Use them in separate cycles for maximum effectiveness, as Bob Vila advises.
