How to Clean a Dishwasher Filter: Quick & Sparkling Results!
To clean a dishwasher filter, remove it from the machine’s floor, rinse under hot water, and scrub with a soft brush to remove debris. Reinsert the filter securely after cleaning. Regular maintenance ensures optimal performance.
Understanding Your Dishwasher Filter

Different Types of Dishwasher Filters
Dishwashers come with two main types of filters: manual and self-cleaning. Manual filters, as the name suggests, require regular cleaning by hand to remove food particles and debris.
They are typically found in older models and are praised for their ability to operate quietly.
Self-cleaning filters, on the other hand, have a grinder that pulverizes food residue, eliminating the need for frequent manual cleaning.
However, they can be a bit noisier during operation. Knowing which type you have is crucial for proper maintenance.
Location of the Filter in Most Dishwashers
The filter is usually located at the bottom of the dishwasher. It can typically be found beneath the lower spray arm, or at the back, depending on your dishwasher’s make and model.
It’s designed to be accessible for cleaning and maintenance purposes. Before attempting to locate your filter, consult your dishwasher’s user manual for specific instructions.
Function of the Dishwasher Filter
The primary function of a dishwasher filter is to trap food particles and prevent them from redepositing on dishes or clogging the drain.
It ensures that the water spraying onto your dishes is clean and helps maintain the efficiency of the dishwasher’s pump and drain.
Keeping the filter clean is essential for the dishwasher to run smoothly and effectively.
Signs That Your Dishwasher Filter Needs Cleaning
You might need to clean your dishwasher filter if you notice dishes are not as clean as they should be or if there is a persistent odor coming from the dishwasher.
Visible food remnants at the bottom of the machine or a longer than usual cycle time are also indicators that the filter may be clogged. Regular inspection can help you identify when it’s time for a clean.
Step-by-Step Guide to Cleaning the Dishwasher Filter

Preparing to Clean the Filter
Gather Necessary Cleaning Supplies
Before you begin, gather your cleaning supplies. You will need hot water, dish soap, a soft brush, and a towel.
If your filter is particularly dirty, you may also need white vinegar for a deeper clean. Ensure you have all these items on hand to streamline the cleaning process.
Empty the Dishwasher
Ensure the dishwasher is empty before you start. This prevents dishes from getting in the way and allows you to reach the filter easily. It’s also a safety measure to avoid breaking any dishes during the cleaning process.
Removing the Filter
To remove the filter, you will usually need to twist it counter-clockwise and lift it out. Some models may have a locking mechanism that needs to be released.
Always handle the filter gently to avoid damaging it. If you encounter resistance, refer to your user manual for specific instructions.
Cleaning the Filter
Rinsing Under Running Water
Begin by rinsing the filter under hot running water. This will help dislodge loose food particles and grime. If your filter has multiple layers, separate them and rinse each one individually.
Soaking in Soapy Water If Necessary
If rinsing alone doesn’t clean the filter thoroughly, fill a basin with hot soapy water and let the filter soak for a few minutes. This will help loosen any stubborn residue that is clinging to the mesh or plastic.
Using a Soft Brush to Remove Stubborn Particles
After soaking, use a soft brush to gently scrub the filter. Be careful not to damage the mesh or plastic.
Scrub in circular motions to ensure you cover all areas of the filter, paying special attention to the corners and crevices where gunk may accumulate.
Rinsing Thoroughly After Cleaning
Once you’ve finished scrubbing, rinse the filter again under hot running water. Make sure all soap and loosened debris are completely washed away.
It’s important that the filter is thoroughly clean to ensure it functions properly when reinserted into the dishwasher.
Inspecting the Filter Housing
With the filter removed, inspect the area where it was seated. Remove any debris you find in the filter housing or the dishwasher’s floor. Wipe the area with a damp cloth to ensure it’s clean before you reinstall the filter.
Reassembling and Maintaining the Dishwasher Filter

Reinserting the Filter
Once the filter is dry, reinsert it into its housing. Make sure it’s properly seated and locked into place. If your filter consists of multiple parts, reassemble them in the correct order before putting them back into the dishwasher.
Tips for Maintaining a Clean Dishwasher Filter
Regular Cleaning Schedule
Establish a regular cleaning schedule for your dishwasher filter. Clean it at least once a month or more often if you use your dishwasher frequently. This will help maintain its performance and prolong the life of your appliance.
Rinsing Dishes Before Loading
Rinsing dishes before loading them into the dishwasher can greatly reduce the amount of food that ends up on the filter. This doesn’t mean you have to wash the dishes by hand; just a quick rinse under the tap can make a difference.
Using the Right Detergents
Use high-quality detergents designed for dishwashers. Cheap or inappropriate detergents can leave residue that clogs the filter and affects cleaning performance.
Running a Dishwasher Cycle Post-Cleaning
After reassembling your dishwasher, run a short cycle without dishes to ensure everything is working correctly.
This also helps to flush out any residue that might have been dislodged during the cleaning process.
Listen for any unusual noises and check that water is flowing properly. If everything sounds and looks good, your dishwasher is ready to get back to work, providing you with clean dishes once again.
