Understanding the Dishwasher Filter: Why It Matters
Before diving into the “where,” let’s briefly cover the “why.” The filter in a dishwasher is a critical component that traps food particles, grease, and debris, preventing them from clogging the drain or redepositing onto your clean dishes. Without regular cleaning, a clogged filter can lead to poor performance, unpleasant odors, or even costly repairs. According to Whirlpool, “A clean filter helps ensure water can circulate freely, keeping your dishes sparkling and your dishwasher running smoothly” ([Whirlpool]).
Most dishwashers have either a manual filter (which you need to remove and clean) or a self-cleaning filter (which grinds up debris automatically). Knowing which type your dishwasher has will clue you in on its location and upkeep.

General Location of the Dishwasher Filter
In most standard dishwashers, the filter is located at the bottom of the appliance, inside the tub. Picture this: you open the dishwasher door, pull out the bottom rack, and look down at the floor of the machine. You’ll typically see a cylindrical or flat component—sometimes covered by a grate or plate—that’s the filter or its housing.
As Maytag explains, “The filter is usually found near the spray arm at the bottom of the dishwasher. It might be a cylindrical piece that twists out or a flat panel you lift up” ([Maytag]). This general placement applies to many popular brands like Whirlpool, KitchenAid, and Samsung, though the exact design varies.
Here’s a step-by-step guide to finding it:
1. Turn off the dishwasher: For safety, unplug it or switch off the power at the breaker.
2. Remove the bottom rack: Slide it out completely to access the base of the tub.
3. Locate the filter: Look for a removable component near the center or back of the bottom surface. It could be a twist-off cylinder, a pull-out tray, or a panel secured with screws.

Brand-Specific Filter Locations
Dishwasher designs differ across manufacturers, so let’s break it down by some of the most popular brands.
1. Bosch Dishwashers
Bosch dishwashers are known for their quiet operation and sleek designs, and their filters are typically easy to spot. The filter is usually a cylindrical unit located at the back center of the dishwasher’s base. According to Bosch’s official support page, “To access the filter, remove the lower rack, then twist the filter counterclockwise to unlock and lift it out” ([Bosch]). Some models also have a secondary coarse filter around it, so keep an eye out for multiple parts.
2. GE Dishwashers
For GE models, the filter is often a flat, rectangular panel or a cylindrical piece at the bottom. GE Appliances advises, “After removing the lower rack, look near the spray arm. If it’s a manual filter, it may require unscrewing or simply lifting out” ([GE Appliances]).
3. Samsung Dishwashers
Samsung dishwashers often feature a filter system near the front or center of the tub floor. Per Samsung’s maintenance guide, “The filter assembly consists of a main filter and a fine filter. Remove the bottom rack, then pull or twist the filter handle to detach it” ([Samsung]).
4. Whirlpool and KitchenAid
These brands, often manufactured under the same parent company, tend to have a similar setup. The filter is typically a cylindrical piece that twists out from the base. Whirlpool notes, “Locate the filter near the back wall or center—give it a quarter turn counterclockwise to remove” ([Whirlpool]).
If you’re unsure about your specific model, check your owner’s manual (often available online via the manufacturer’s website by entering your model number).

Types of Dishwasher Filters
Not all filters are created equal. Here’s a closer look at the two main types you’ll encounter:
- Manual Filters: These require periodic removal and cleaning. They’re common in brands like Bosch and Samsung, offering superior filtration but demanding more hands-on maintenance. You’ll need to rinse them under warm water and scrub gently with a soft brush to remove buildup.
- Self-Cleaning Filters: Found in many Whirlpool and GE models, these use a grinder to pulverize food particles, flushing them down the drain. While low-maintenance, they can be noisier and less effective if large debris gets trapped.
Consumer Reports highlights the trade-off: “Manual filters catch more debris but need regular cleaning, while self-cleaning ones save time but might not handle heavy loads as well” ([Consumer Reports]).

How to Clean the Filter (Once You’ve Found It)
Once you’ve located the filter, cleaning it is straightforward:
1. Remove the filter: Twist, pull, or unscrew it based on your model’s design.
2. Rinse it: Use warm, soapy water and a soft brush or sponge to dislodge grease and debris. Avoid harsh scrubbers that could damage the mesh.
3. Inspect the housing: Wipe down the area where the filter sits to remove any leftover gunk.
4. Reinstall: Secure the filter back in place, ensuring it locks properly.
The Spruce recommends cleaning the filter monthly, noting, “A quick rinse can prevent odors and keep your dishwasher humming along” ([The Spruce]).

Additional Tips for Dishwasher Maintenance
Finding and cleaning the filter is just one part of dishwasher care. Here are some bonus tips to extend its life:
- Scrape dishes before loading: Large food scraps can overwhelm even the best filters.
- Run a vinegar cycle: Place a cup of white vinegar on the top rack and run a hot cycle every few months to break down grease and limescale.
- Check the spray arms: Clogged holes can reduce water flow, putting extra strain on the filter.

Frequently Asked Questions (FAQ)
1. How do I know if my dishwasher has a filter?
Every dishwasher has some form of filtration. Check your manual or look at the bottom of the tub after removing the lower rack. If you see a removable component, it’s likely a manual filter; if not, it might be self-cleaning.
2. How often should I clean the filter?
For manual filters, aim for once a month or if you notice poor cleaning performance. Self-cleaning filters rarely need attention but should be checked if drainage issues arise.
3. What happens if I don’t clean the filter?
A clogged filter can cause dirty dishes, bad smells, or water backup. In severe cases, it might damage the pump, leading to costly repairs.
4. Can I run my dishwasher without the filter?
No, the filter protects the pump and drain system. Running it without one risks clogs and mechanical failure.
5. Why does my dishwasher smell bad even after cleaning the filter?
Check for trapped debris in the spray arms, door gasket, or drain hose. A vinegar cycle can also help eliminate lingering odors.
