Dishwashers are a modern-day convenience that can save you time and effort while keeping your kitchenware clean.
However, there may be times when you notice a fishy smell (similar to algae from a fish tank) coming from your dishwasher, making your cleaning experience less enjoyable.
Don’t worry, this is a common issue, and there are practical solutions to help you get rid of the unpleasant odor.
One primary cause of fishy smell in dishwashers is a buildup of food particles, grease, and residues.
These elements can form in various parts of your dishwasher, such as the filter, interior walls, or drain. Understanding how to maintain and clean your dishwasher is crucial for keeping it smelling fresh and working effectively.
To tackle the fishy smell, it’s essential to pinpoint the source and apply proper cleaning techniques.
In the following sections, we will explore some proven strategies to eliminate that pesky odor and keep your dishwasher smelling fresh for optimal kitchen hygiene.
Understanding the Causes of Fishy Smell in Dishwasher
Let’s first go through some of the reasons that can lead to fishy smell in the dishwasher.
Bacteria and Food Debris
A common cause of the fishy smell in a dishwasher is the buildup of bacteria and food particles.
When you use your dishwasher, it’s normal for small food particles to get trapped inside the machine.
Over time, these particles can begin to decompose and create an environment where bacteria can grow and produce a fishy smell.
To maintain a clean dishwasher, clean the filter regularly to remove any trapped food debris.
This will help prevent bacterial growth and minimize the chances of developing a fishy odor.
Additionally, always scrape your dishes before loading them into the dishwasher to reduce the amount of food particles entering the machine.
Poor Cleaning and Contamination
Another cause of the fishy smell in a dishwasher could be the result of poor cleaning practices or contamination from other sources.
Using too little or the wrong type of dishwashing detergent can contribute to the problem.
The detergent you choose should be designed explicitly for dishwashers and capable of effectively breaking down grease and food particles.
To ensure a thorough clean, make sure you’re using the appropriate amount of detergent according to the manufacturer’s instructions.
Additionally, check the dishwasher’s spray arms for clogs, as this can impact water flow and cleaning efficiency.
Bacterial Growth Due to Less Usage
Bacterial growth in the dishwasher can also cause a fishy smell.
This can occur if the machine is not frequently used, creating a moist environment that encourages bacteria to breed.
To combat this issue, try to run your dishwasher more frequently, and leave the door open slightly after each cycle to let excess moisture evaporate.
Moreover, consider using a dishwasher cleaner or a vinegar solution to clean your machine periodically.
This can help remove any residual bacteria, ensuring that your dishwasher remains clean and fresh-smelling.
By understanding the causes of fishy smell in your dishwasher and addressing them, you can maintain a sanitary and odor-free appliance.
Proper cleaning techniques, regular usage, and detergents designed for dishwashers will help keep your machine fresh and ready for your next load of dishes.
Another possible reason many people believe can cause a fishy smell is the algae in the water supply. Here is a great discussion about it.

How to Prevent Fishy Smell in Dishwasher
Now that you understand the possible reasons that can cause a fishy smell in your dishwasher, let’s learn a few techniques to prevent this smell.
Proper Loading of Dishes
To avoid a fishy smell in your dishwasher, always make sure you properly load your dishes.
Place larger items like pots and pans on the bottom rack and smaller items such as plates and cups on the top rack.
Ensure that the soiled surfaces face the center of the dishwasher to promote better water circulation.
Proper loading allows your dishwasher to clean all surfaces effectively, preventing the buildup of bacteria that may cause a fishy smell.
Regular cleaning is crucial in maintaining a fresh-smelling dishwasher. Remove any food debris from the filter and the dishwasher’s interior after each cycle.
Wipe the surfaces with a damp cloth to eliminate any grease or residues. Run a hot water cycle with dishwasher detergent on an empty dishwasher at least once a month to thoroughly clean and disinfect it.
This will prevent mold and mildew growth that may contribute to a fishy smell.
Perform Routine Maintenance
Performing routine maintenance on your dishwasher helps in preventing unpleasant odors.
Clean the dishwasher gasket regularly to remove any trapped debris. Also, inspect and clean the spray arms to ensure proper water flow.
Use a vinegar and water solution to clean and disinfect the dishwasher’s interior.
Occasionally, run a cycle with a specialized dishwasher cleaner to maintain your appliance’s performance and keep unpleasant smells at bay.
Use the Right Detergent/Tablets
Always use recommended dishwasher detergent and avoid using regular dish soap as it may cause excessive sudsing that can damage your appliance.
Opt for antibacterial detergents, which help eliminate bacteria that may cause fishy smells.
Moreover, avoid overloading the dishwasher as it may lead to poor water circulation and residual food debris.
Following these tips on proper loading, regular cleaning, maintenance, and safety precautions will prevent fishy smells from developing in your dishwasher, ensuring a clean and fresh appliance for everyday use.

To get rid of the fishy smell in your dishwasher, it’s essential to clean its components thoroughly.
This section will provide detailed guidance on how to clean the dishwasher filter, gasket and seals, bottom rack, and spray arm.
Cleaning Dishwasher Filter
Dishwasher filters come in two types: manual filters and self-cleaning filters.
Regardless of the type, keeping your dishwasher filter clean is crucial in eliminating unpleasant odors.
- Manual filters: Locate the filter at the bottom of your dishwasher, usually below the bottom rack. Remove the filter and clean it with hot, soapy water. Use a soft bottle brush to reach deep into the filter’s crevices. Ensure no food particles are left behind before reinstalling the filter.

Cleaning Gaskets and Seals
The gaskets and seals in your dishwasher help prevent leaks and maintain a watertight seal.
Cleaning them regularly will not only reduce odors but also prolong their lifespan.

- Use a soft sponge or rag to apply the paste to the gaskets and seals.
- Scrub gently to avoid damaging the delicate material.
- Rinse with clean water and dry with a soft cloth.
Cleaning Bottom Rack and Spray Arm
The bottom rack and spray arm are essential components in the washing cycle.
Keeping them clean will ensure your dishwasher operates efficiently and without unpleasant smells.
- Bottom Rack: Remove the bottom rack from the dishwasher and inspect for trapped food particles or debris. Use a soft brush to clean any nooks and crannies, then rinse the rack thoroughly with warm water.
- Spray Arm: Locate the spray arm, usually at the bottom of the dishwasher. Carefully remove and clean the spray arm ports. Use a small brush to clean the spray arm holes, ensuring no food particles or debris are left behind. Reinstall the spray arm once it is clean.
By following these steps, you’ll be on your way to a fresher-smelling dishwasher.
