A smelly dishwasher can be a real nuisance, turning your kitchen into a less-than-pleasant space. One particularly unpleasant odor is that of wet dog, which can linger even after a cycle is complete. Understanding why your dishwasher smells like wet dog is crucial for addressing the issue and restoring your appliance to its fresh-smelling best.
Why Does My Dishwasher Smell Like Wet Dog?
The “wet dog” smell in your dishwasher is often caused by the growth of mildew or mold. These microorganisms thrive in warm, damp environments, and your dishwasher’s interior, with its frequent exposure to moisture, provides the perfect breeding ground.
Factors Contributing to the Smell
Several factors can contribute to the development of mildew and mold in your dishwasher, leading to that distinctive wet dog odor:
- Food Debris: Leftover food particles trapped in the dishwasher can decompose and create an environment conducive to microbial growth.
- Moisture Buildup: If your dishwasher doesn’t dry completely after a cycle, standing water can encourage mildew and mold development.
- Poor Ventilation: Insufficient airflow within the dishwasher can trap moisture and odors.
- Detergent Buildup: Overuse of dishwasher detergent or the use of the wrong type can leave a residue that promotes microbial growth.
Why Does My Dishwasher Smell Like Wet Dog?
A wet dog smell coming from your dishwasher is a common problem that can be quite unpleasant. This odor usually indicates a buildup of bacteria and organic matter within your dishwasher. Fortunately, there are several steps you can take to identify the source of the smell and eliminate it.
Possible Causes of the Wet Dog Smell
Several factors can contribute to the musty, wet dog odor in your dishwasher:
Food Debris
Leftover food particles trapped in the filter, spray arms, or other crevices can decompose and create a foul smell.
Mold and Mildew
Moisture trapped inside the dishwasher, especially in warm, humid environments, can lead to mold and mildew growth. These organisms produce the characteristic wet dog odor.

Using too much detergent or using a detergent that doesn’t rinse properly can leave behind a residue that attracts bacteria and contributes to odors.
Drainage Issues
A clogged drain hose or garbage disposal can prevent water from draining completely, leading to stagnant water and odor-causing bacteria.
How to Get Rid of the Wet Dog Smell
Here are some steps you can take to eliminate the wet dog smell from your dishwasher:
Clean the Filter
The dishwasher filter is a common culprit for odors. Remove the filter and wash it thoroughly with hot, soapy water.
Clean the Spray Arms
Inspect the spray arms for food debris and mineral buildup. Remove any clogs and clean them with a brush and hot, soapy water.
Run an Empty Cycle with Vinegar
Pour one cup of white vinegar into the bottom of the dishwasher and run an empty hot cycle. Vinegar is a natural disinfectant and deodorizer.
Clean the Door Gasket
The door gasket can trap food particles and moisture. Wipe it down with a damp cloth and baking soda solution.
Check the Drain Hose and Garbage Disposal
Make sure the drain hose is not kinked or clogged. If necessary, clean the garbage disposal to prevent food particles from backing up into the dishwasher.
Use the Right Amount of Detergent
Follow the detergent manufacturer’s instructions for the correct amount to use. Using too much detergent can leave behind a residue that contributes to odors.
Leave the Dishwasher Door Ajar
After each use, leave the dishwasher door slightly ajar to allow it to air out and prevent moisture buildup.
Preventing Future Odors
Once you’ve eliminated the wet dog smell, take steps to prevent it from returning:
- Clean the filter regularly.
- Wipe down the interior of the dishwasher after each use.
- Don’t overload the dishwasher.
- Use the right amount of detergent.
- Leave the door ajar after each cycle.
Recap
A wet dog smell in your dishwasher is often caused by food debris, mold, mildew, detergent buildup, or drainage issues. By cleaning the filter, spray arms, and door gasket, running an empty cycle with vinegar, and checking the drain hose, you can eliminate the odor. Preventing future smells involves regular cleaning, proper loading, and using the right amount of detergent.
