How to Stop Your Dishwasher from Smelling Funky

A dishwasher is one of the most convenient kitchen appliances, saving time and effort after meals. But when it starts to smell, it quickly becomes a nuisance. Funky odors can persist no matter which soap you use, leaving you frustrated. Understanding the causes can help you tackle the problem—even if a repair person isn’t available right away.

Check the Food Filter First

A clogged food filter is one of the top causes of dishwasher odors. It catches leftover food but can get blocked over time.

Fix it:

• Locate the filter at the bottom of your dishwasher.

• Remove any debris and rinse under hot water.

• For stubborn grime, scrub with a soft brush and mild detergent.

Regular cleaning prevents blockages and keeps smells away.

Clear the Spray Arms

Spray arms distribute water to clean your dishes, but food particles and mineral deposits can clog them.

Fix it:

• Remove the arms (unscrew or pull gently).

• Use a toothpick or thin wire to clear spray holes.

• Rinse under running water and reattach.

This simple step boosts cleaning and reduces odors.

Clean the Door Gasket

The rubber seal around the door can collect slime and mold.

Fix it:

• Wipe the gasket with a cloth soaked in warm water and vinegar or mild soap.

• Focus on folds and crevices.

Cleaning the gasket prevents mold growth and keeps smells in check.

Inspect for Standing Water

Standing water at the bottom signals drainage issues. Bacteria can grow and cause bad odors.

Fix it:

• Check the drain hose for kinks or blockages.

• Inspect the drain pump and remove debris.

Proper drainage is essential for a fresh-smelling dishwasher.

Don’t Forget the Garbage Disposal

A clogged kitchen disposal can back up odors into your dishwasher.

Fix it:

• Run the disposal with cold water for a few minutes.

• Use a disposal cleaner or baking soda and vinegar to freshen it.

Keeping the disposal clean prevents odors from transferring.

Deep-Clean the Interior

Dishwasher detergent cleans dishes but may not remove grease buildup inside.

Fix it:

• Run an empty cycle with a dishwasher cleaner or a cup of white vinegar on the top rack.

• Repeat monthly for best results.

Deep cleaning dissolves grease and keeps smells away.

Prevent Mold by Air-Drying

Mold and mildew thrive in damp, dark places. Keeping the door shut traps moisture.

Fix it:

• Leave the door slightly ajar after cycles to let the dishwasher dry.

This simple habit prevents mold and odors.

Use the Right Detergent

Too much soap or the wrong type can create suds that trap odors.

Fix it:

• Use detergent made for dishwashers.

• Follow the recommended amount based on water hardness and soil level.

Correct detergent use improves cleaning and prevents smells.

Try Vinegar and Baking Soda

Vinegar and baking soda are safe, effective odor-fighting tools.

Fix it:

• Run a hot cycle with a cup of vinegar on the top rack.

• Sprinkle baking soda across the bottom and run a short cycle.

• Avoid using them together in the same cycle to prevent excess foaming.

This neutralizes odors and removes minor buildup.

Manage Hard Water and Limescale

Limescale can trap odors and reduce dishwasher performance.

Fix it:

• Use a limescale remover or dishwasher cleaner.

• Consider a water softener or rinse aid in hard water areas.

Regular descaling keeps your dishwasher fresh.

Inspect the Drain Hose

A kinked or damaged hose can trap water and cause smells.

Fix it:

• Check for kinks, loops, or rot.

• Replace damaged hoses to restore proper drainage.

Load Dishes Properly

Incorrect loading blocks water and detergent, leaving residue behind.

Fix it:

• Space dishes according to the manufacturer’s guidelines.

• Avoid overloading.

Proper loading prevents odors and ensures thorough cleaning.

Adopt Regular Maintenance Habits

Consistency is key to a fresh dishwasher.

Tips:

• Clean the filter, spray arms, and gasket regularly.

• Run monthly cleaning cycles with vinegar or a dishwasher cleaner.

• Ensure proper drainage and air-dry after use.

These habits keep your dishwasher smelling fresh and working efficiently.
