ToggleWhy Should You Clean Your Dishwasher Filter
A dirty filter can lead to subpar performance if accumulated debris impedes water circulation. For one thing, it can prevent the bottom spray arm from working properly.
Leftover residue may also cause unpleasant odors or potentially damage the dishwasher tub and other delicate parts within the machine, leading to costly repairs or shortening the dishwasher’s lifespan.
Impact on Cleanliness and Efficiency
Not only that but a dirty filter can also affect the cleanliness of your dishes. For example, residue build-up can prevent water from circulating properly during washing.
Understanding Different Types of Dishwasher Filters
There are two main types – manual and self-cleaning filters, each of which has its own unique characteristics and maintenance requirements.

Newer models typically come equipped with manual filters that trap food particles during the wash cycle to prevent them from landing back onto your clean dishes.
Older dishwashers, on the other hand, usually come with self-cleaning filters, which grind up food debris before washing them down the drain.
While this type requires less hands-on maintenance compared to their manual counterparts, they tend to make more noise due to the grinding process involved.
Identifying Your Dishwasher Filter Type
Before you try to get your dishwasher filter clean, you want to identify the type that you have.
Figuring out if you have a manual or self-cleaning filter is not hard when you know where to look.
If you need help, refer to the owner’s manual. If you no longer possess a physical copy, don’t worry – most manufacturers offer digital versions online via their official websites.
Locating and Removing Your Dishwasher Filter
The upper filter is typically nestled at the bottom of the dishwasher, and tucked under the lower dish rack. However, this location may vary based on your specific dishwasher model.
To locate it, start by removing the bottom rack. Once you’ve done that, look for the cylindrical filter. Turn the filter clockwise, gently lift the piece and it should come right out.
In some models, it might be located around or beneath an important component known as the spinning dishwasher spray arm.
Removing Flat Filters
Certain dishwashers come equipped with another flat filter/lower filter that’s located underneath the standard filter. Its job is to capture any food particles or debris that managed to sneak past its comrade above.
To clean the flat filter, simply lift gently after unscrewing or popping out its counterpart situated right above it. Remember, these filters aren’t invincible warriors but delicate parts of your appliance, so handle them carefully.
How to Clean Dishwasher Filter
Cleaning a dishwasher filter is easier than you think.
Keeping Your Dishwasher Filter In Tip-Top Shape
Step 1: Rinse the Filter

Rinse off any loose debris from the removed filter under warm water. If stubborn grime persists, wash gently using a soft brush and a soapy solution.
Step 2: Soak the Filter In Vinegar

If you’re looking for deep-cleaning methods for your manual dishwasher filters, consider soaking them overnight in white distilled vinegar.
Distilled white vinegar, due to its acidic nature, will help break down mineral deposits and grease without causing harm to the appliance parts, such as the dishwasher tub.
Step 3: Apply Baking Soda

Apply a generous amount of baking soda over the wet surface. Baking soda will act as a natural abrasive, removing food residue from the machine while also eliminating odors.
Step 4: Rinse the Filter Again

Rinse the filter thoroughly before placing it back into its original position within the machine. Make sure the filter is seated properly prior to running another cleaning cycle with hot water.
Supply:
- Soft bristle brush
- White vinegar
- Mild dish soap
- Baking soda
- Water
Avoid using a wire brush and harsh detergents when dealing with your dishwasher filter. These could potentially harm the component’s structure.

How Often Should You Clean Your Dishwasher Filter?
Cleaning the dishwasher filter isn’t a task to be done once and forgotten. It’s an ongoing chore that requires regular attention for optimal performance of your appliance. That’s right, routine maintenance is key.
The frequency of cleaning the filter depends on various elements, such as the kind of dishes washed and how often you use your dishwasher.
If you frequently deal with heavily soiled pots or run multiple cycles per day, it may necessitate more frequent cleanings.
Maintaining Regular Cleaning Schedules
Experts suggest that manual dishwasher filters should be cleaned once every month for best results. That will prevent food residue from interfering with the dishwasher’s effectiveness – resulting in sparkling clean dishes after every operation.

Apart from cleanliness, regularly maintaining your dishwasher’s filter can also extend its lifespan by preventing undue strain on other components such as the pump and motor.
Frequent Cleaning: A Preventive Measure
If neglected over time, grime build-up could lead to blockages causing these parts to work harder during each cycle – potentially leading to premature failure over time.
That’s why it’s so important to clean the filter with mild detergent on a regular basis.
