Why Does My Dishwasher Smell?
Before tackling the problem, it’s helpful to understand why dishwashers develop odors. According to the experts at Good Housekeeping, “A smelly dishwasher is usually the result of food debris and grease building up over time, often in hidden spots like the filter, spray arms, or door gasket.” Mold, mildew, and bacteria thrive in the warm, moist environment, especially if dishes sit for too long before a cycle or if the machine isn’t cleaned regularly. Hard water deposits or a clogged drain can also contribute to the funk.
Understanding these culprits sets the stage for effective solutions. Let’s start with the basics.

Step-by-Step Cleaning Methods
1. Inspect and Clean the Filter
The filter is often the primary source of dishwasher odors. GE Appliances advises, “Check your owner’s manual to locate the filter—typically at the bottom of the dishwasher—and remove it carefully.” Once out, rinse it under warm water with a soft brush to dislodge food particles and grease. For stubborn debris, soak it in a mix of warm water and dish soap for 10-15 minutes before scrubbing. Dry it completely and reinstall.
*Pro Tip*: Some filters aren’t removable. If yours isn’t, use a damp cloth or toothbrush to clean it in place.
2. Wipe Down the Interior
Food splatter and grime can cling to the walls, door, and rubber gasket. The Spruce recommends, “Use a damp cloth with a bit of white vinegar to wipe down the interior surfaces, focusing on the gasket where mold loves to hide” [(( The Spruce ))]. Vinegar’s acidity cuts through grease and neutralizes odors naturally. Avoid abrasive scrubbers—they can damage the finish.
3. Run a Vinegar Cycle
White vinegar is a powerhouse for deodorizing. Consumer Reports suggests, “Place a dishwasher-safe bowl filled with 1-2 cups of white vinegar on the top rack, then run a hot water cycle.” The steam distributes the vinegar, breaking down mineral deposits and killing odor-causing bacteria. Don’t mix vinegar with detergent—it’s most effective alone.
4. Follow Up with Baking Soda
After the vinegar cycle, sprinkle 1 cup of baking soda across the bottom of the dishwasher and run a short, hot cycle. Bob Vila notes, “Baking soda absorbs lingering odors and gently scrubs away residue, leaving your dishwasher smelling fresh” [(( Bob Vila ))]. This one-two punch of vinegar and baking soda is a classic, chemical-free fix.
5. Check and Clean the Spray Arms
Clogged spray arms can trap food and cause smells. Remove them (consult your manual) and rinse under running water. Use a toothpick or small brush to clear the tiny holes. Whirlpool advises, “Ensure the arms spin freely before reattaching—this ensures proper cleaning and water flow.”

Preventative Maintenance Tips
Cleaning is only half the battle—keeping odors at bay requires consistent habits.
1. Scrape Dishes Before Loading
Kitchn emphasizes, “You don’t need to pre-rinse, but scraping off large food chunks prevents buildup in the filter and drain.” This small step reduces the organic material that feeds odors.
2. Run the Dishwasher Regularly
Letting dirty dishes sit for days invites bacteria to multiply. Run a cycle every 1-2 days, even if it’s not full, to keep things fresh.
3. Use the Right Detergent
Low-quality detergents can leave residue that smells over time. Opt for a reputable brand and avoid overloading the dispenser.
4. Dry It Out
After each cycle, leave the door ajar for an hour. HGTV explains, “Moisture is the enemy of a fresh dishwasher—air circulation helps prevent mold growth.”
5. Check the Drain Hose
A kink or clog in the drain hose can trap water and stink up the machine. Inspect it yearly and straighten or clear it as needed.

Supplementary Information: Going Beyond the Basics
Natural Odor Absorbers
For a passive solution, place a small bowl of activated charcoal or coffee grounds inside the dishwasher between uses. These absorb odors without any effort.
Addressing Hard Water Issues
If your water is hard, limescale can exacerbate smells. Maytag recommends running a cycle with a dishwasher cleaner like Affresh or a citric acid powder monthly to descale the machine.
When to Call a Professional
Persistent odors despite cleaning might signal a deeper issue, like a malfunctioning pump or drain. Contact a technician if the smell lingers after trying these fixes.

Q: Why does the smell come back quickly?
A: Check for hidden food traps (filter, arms) or poor drying habits. Consistent prevention is key.
Q: Are commercial dishwasher cleaners worth it?
A: Products like Affresh or Finish Cleaner work well for tough buildup, especially in hard water areas. They’re a convenient alternative to DIY methods.
