Why Does My Dishwasher Smell?
Before tackling the odor, it’s helpful to understand what’s causing it. Dishwasher smells typically stem from trapped food particles, grease, mildew, or mold buildup. Over time, these culprits can fester in hidden areas like the filter, drain, or door gasket. Hard water deposits or detergent residue can also contribute to funky smells if not addressed.
According to the experts at Consumer Reports, “Food scraps can get trapped in crevices or filters, and if they’re not cleaned out regularly, they’ll start to rot and produce a bad smell.” Poor drainage or infrequent use can exacerbate the issue, leaving standing water that becomes a breeding ground for bacteria. Knowing the root cause will guide you to the right solution.

Step-by-Step Methods to Remove Dishwasher Odor
1. Start with a Basic Cleaning
First things first: give your dishwasher a thorough once-over. Remove any visible debris from the bottom of the dishwasher and check the filter (if your model has one). Many modern dishwashers have a removable filter that traps food particles—consult your manual to locate it.
- How to Clean the Filter: Take it out, rinse it under warm water, and scrub gently with a soft brush or sponge. The folks at Whirlpool recommend doing this monthly: “A clogged filter can prevent proper drainage, leading to odors.” [(( Whirlpool ))]
- Wipe Down Surfaces: Use a damp cloth with a bit of dish soap to clean the door gasket, edges, and interior walls where grime can hide.
2. Run a Vinegar Cycle
Vinegar is a natural deodorizer and a go-to solution for cutting through grease and mineral buildup. Here’s how to do it:
- Place a dishwasher-safe bowl or cup filled with 1-2 cups of white vinegar on the top rack.
- Run a hot water cycle (no dishes, just the vinegar). The heat and acidity will break down odor-causing residue.
Good Housekeeping swears by this method: “Vinegar’s acetic acid helps dissolve stuck-on food and neutralizes smells without harsh chemicals.” [(( Good Housekeeping ))]
3. Follow Up with Baking Soda
After the vinegar cycle, baking soda can absorb lingering odors and scrub away stubborn stains. Sprinkle about 1 cup of baking soda across the bottom of the dishwasher and run a short, hot cycle.
Per The Spruce, “Baking soda is mildly abrasive, so it cleans while also tackling odors—think of it as a gentle polish for your dishwasher.” This one-two punch of vinegar and baking soda is a classic combo for a reason—it works!
4. Clean the Drain and Spray Arms
If the smell persists, the drain or spray arms might be harboring gunk. Check the drain at the bottom of the dishwasher for trapped debris—use gloves and a flashlight to scoop out anything nasty. For the spray arms, remove them (if detachable) and rinse the tiny holes under running water to clear clogs.
GE Appliances advises, “Food and grease can accumulate in these areas, so a quick check can make a big difference in odor control.”
5. Use a Commercial Dishwasher Cleaner (Optional)
For tough odors or if you prefer a ready-made solution, try a product like Affresh or Finish Dishwasher Cleaner. Follow the package instructions—usually, you place a tablet or pouch in the dishwasher and run a cycle. These cleaners are formulated to tackle limescale, grease, and bacteria.

Extra Tips to Enhance Odor Removal
Tackle Hard Water Buildup
If you live in a hard water area, mineral deposits can trap odors. Bob Vila suggests using citric acid: “Fill the detergent dispenser with powdered citric acid (available at hardware stores) and run a normal cycle. It’ll descale your machine and leave it smelling fresh.” [(( Bob Vila ))]
Deodorize with Lemon
For a natural, pleasant scent, toss a few lemon peels or a halved lemon into the silverware basket during a cycle. The citrus oils cut grease and leave a clean aroma.
Check the Plumbing
A lingering sewer-like smell might point to a drainage issue beyond the dishwasher. Ensure the drain hose isn’t kinked and that your sink’s garbage disposal (if connected) is clean. A plumber might be needed if the problem traces back to your pipes.

Preventing Dishwasher Odors Long-Term
Odor removal is only half the battle—keeping smells at bay requires consistent habits:
- Scrape Dishes Before Loading: Rinse off big food chunks to prevent buildup.
- Run the Dishwasher Regularly: Stagnant water breeds bacteria, so don’t let it sit unused for weeks.
- Leave the Door Ajar: After a cycle, let the interior air-dry to discourage mold growth.
- Use the Right Detergent: Cheap or incompatible detergents can leave residue that smells over time. Stick to a reputable brand suited for your machine.
Maytag notes, “A little maintenance goes a long way—clean your dishwasher every month or two, and you’ll rarely deal with odors.”

Common Problem Areas and Solutions
- Rubber Gasket: Mold loves this spot. Wipe it with a vinegar-soaked cloth weekly.
- Utensil Basket: Food can get stuck in tight spaces—rinse it separately if needed.
- Hidden Crevices: Use an old toothbrush to scrub corners where sponges can’t reach.

FAQs About Dishwasher Odors
Q: How often should I clean my dishwasher to prevent smells?
A: Aim for a deep clean every 1-2 months, though wiping down the gasket and checking the filter weekly helps too.
Q: Can I use bleach to get rid of the odor?
A: Yes, but only for stainless steel interiors—use ½ cup in a cycle. Avoid bleach with plastic interiors, as it can damage parts. Check your manual first.
Q: Why does my dishwasher still smell after cleaning?
A: Persistent odors might mean a clogged drain, plumbing issue, or mold deep in the system. Inspect the drain or call a pro.
Q: Are dishwasher pods better than powder for odor control?
A: Not necessarily—both can work well if used correctly. Pods are convenient, but excess powder can leave residue if not fully dissolved.
Q: Can I combine vinegar and baking soda in one cycle?
A: No, they’ll neutralize each other. Run them separately for best results.
