Why Does Mold Grow in Dishwashers?
Dishwashers are warm, moist environments—perfect breeding grounds for mold. According to the experts at Maytag, “Mold thrives in damp, dark places, and leftover food particles or grease can serve as a food source for mold growth” [(( Maytag ))]. Poor ventilation, infrequent cleaning, or leaving wet dishes inside for too long can all contribute to the problem. Understanding this helps you tackle the root cause while cleaning.

Step-by-Step Guide to Remove Mold from Your Dishwasher
Step 1: Safety First—Prepare Your Workspace
Before you start, unplug the dishwasher to avoid any electrical hazards. Put on rubber gloves to protect your hands from mold spores and cleaning agents. Open the dishwasher door and let it air out for a few minutes to reduce moisture.
Step 2: Inspect and Remove Debris
Check the dishwasher’s filter, drain, and spray arms for food scraps or buildup. “Remove the bottom rack and look at the drain under it—rinse off any gunk you find there,” advises Good Housekeeping [(( Good Housekeeping )]. Use a damp cloth or an old toothbrush to scrub away visible debris.
Step 3: Clean with Vinegar
Vinegar is a natural mold killer thanks to its acidity. Here’s how to use it:
1. Place a dishwasher-safe bowl filled with 1-2 cups of white vinegar on the top rack.
2. Run a hot water cycle (no dishes inside). The heat and vinegar will break down mold and mildew.
3. After the cycle, wipe down the interior with a vinegar-soaked cloth, focusing on rubber seals and crevices where mold hides.
As The Spruce notes, “Vinegar is highly effective at removing mold stains and odors from dishwashers” [(( The Spruce ))].
Step 4: Tackle Stubborn Mold with Baking Soda
For tougher spots, sprinkle baking soda on a damp sponge and scrub the affected areas. “Baking soda acts as a mild abrasive and deodorizer, making it great for lingering mold,” says Bob Vila. Rinse thoroughly with warm water afterward.
Step 5: Use Bleach (Optional, with Caution)
If the mold persists, bleach can be a last resort—but only for non-stainless-steel interiors. Mix ¾ cup of bleach with a gallon of water, wipe down the interior, and run a short rinse cycle. “Never mix bleach with vinegar, as it creates toxic fumes,” warns GE Appliances.
Step 6: Dry and Inspect
Wipe the interior with a dry microfiber cloth and leave the door ajar to air-dry completely. Check for any remaining mold spots—if you see any, repeat the vinegar or baking soda steps.

Preventing Mold Growth in Your Dishwasher
Cleaning is only half the battle; prevention is key. Here are some practical tips:
- Run Regular Cleaning Cycles: Once a month, run an empty cycle with vinegar or a dishwasher cleaner like Affresh.
- Dry After Use: Leave the door slightly open after each cycle to let moisture escape.
- Clean the Filter: Rinse the filter weekly to remove food particles.
- Check Seals: Mold loves rubber gaskets. Wipe them down with vinegar regularly.
“Keeping your dishwasher dry and free of debris is the best way to stop mold before it starts,” explains Whirlpool [(( Whirlpool ))].

Additional Tips and Tricks
Use Commercial Cleaners
Products like Affresh Dishwasher Cleaner or Finish Dishwasher Cleaner are designed to tackle mold and limescale. Follow the package instructions—usually, you just pop a tablet in and run a cycle.
Try Citric Acid for Tough Cases
For heavy mold or mineral deposits, citric acid can work wonders. Add ¼ cup to the detergent dispenser and run a hot cycle. It’s a favorite trick from appliance repair blogs like Fix Appliances CA.
Address Hard Water Issues
If your water is hard, limescale can trap moisture and encourage mold. Use a rinse aid or install a water softener to minimize buildup.

Common Causes of Persistent Mold
Sometimes mold keeps coming back despite your efforts. Here’s why:
- Leaking Seals: Damaged gaskets can trap water. Inspect and replace them if needed.
- Clogged Drain: A blocked drain keeps water pooling. Clear it with a plumber’s snake if necessary.
- Old Appliance: Older dishwashers may have cracks or worn parts that harbor mold.
