Why Does a Dishwasher Have a Filter?
Before diving into where the filter is, it’s worth understanding its purpose. The filter in a dishwasher traps food particles, grease, and debris that come off your dishes during the wash cycle. Without it, these bits could clog the drain or redeposit onto your supposedly clean dishes—not a pleasant thought! Some dishwashers even have self-cleaning filters that grind up debris, but most require manual cleaning for optimal performance.
According to Whirlpool, “The dishwasher filter is essential to the cleaning process because it prevents food from being redeposited on your dishes while also protecting the pump from becoming clogged with debris.”[(( Whirlpool ))] Keeping it clean can also extend the life of your appliance and prevent funky odors.

Where to Find the Filter: A General Guide
The location of the filter can vary slightly depending on the make and model of your dishwasher, but in most cases, it’s found inside the dishwasher, at the bottom. Here’s a general step-by-step guide to locating it:
1. Open the Dishwasher Door: Ensure the appliance is off and cool if it’s recently run a cycle.
2. Remove the Bottom Rack: Slide out the lower dish rack to access the base of the dishwasher tub.
3. Look for the Filter Assembly: The filter is typically located in the back corner or center of the dishwasher floor. It might look like a cylindrical or flat component, often with a twist-off cap or a removable cover.
Most filters are either a single removable piece or part of a two-piece system (a coarse filter and a fine filter). If it’s not immediately obvious, check for a small hatch or panel that can be lifted or twisted off.

Types of Dishwasher Filters and Their Locations
Dishwasher filters come in two main types: manual and self-cleaning. Knowing which type you have can help you pinpoint its location.
Manual Filters
These require you to remove and clean them periodically. They’re often larger and more accessible. As Maytag explains, “Manual clean filters are commonly found on the dishwasher floor near the spray arm or at the back of the tub.”[(( Maytag ))] You might need to twist or pull the filter to remove it—consult your manual if it feels stuck.
Self-Cleaning Filters
Self-cleaning (or “hard food disposer”) filters grind up debris so you don’t have to clean them as often. These are usually integrated into the pump system at the bottom and might not be removable. Bosch, a brand known for quiet dishwashers, notes, “Our dishwashers often feature a three-filter system that’s partially self-cleaning, located at the base near the drain.”[(( Bosch ))]
To determine your filter type, check your user manual or look for grinding noises during operation—a clue you’ve got a self-cleaning model.

Brand-Specific Filter Locations
Since filter placement can differ by brand, here’s a breakdown based on popular manufacturers:
1. GE Dishwashers
GE dishwashers typically have a filter at the bottom center or back corner. According to GE Appliances, “To access the filter, remove the bottom rack, then locate the cylindrical filter assembly. Twist counterclockwise to remove it.” This applies to most standard models.
2. Samsung Dishwashers
Samsung places its filters near the bottom front of the tub. A Samsung support page advises, “After removing the lower rack, find the filter cover—a rectangular panel—and lift it to access the filter beneath.”
3. KitchenAid
KitchenAid often uses a two-part filter system. “The upper filter catches larger debris, while the lower fine filter traps smaller particles. Both are found at the bottom center,” per KitchenAid’s official care guide.
4. LG Dishwashers
LG’s filters are usually under a small cover at the back of the tub floor. “Remove the bottom rack, then unscrew or lift the filter housing to pull it out,” LG’s maintenance tips suggest.
If you’re unsure about your specific model, the user manual is your best friend—or search your model number online for a diagram.

How to Remove and Clean the Filter
Once you’ve located the filter, cleaning it is straightforward:
1. Remove the Filter: Twist, pull, or lift it out, depending on the design. Some may have a locking mechanism—don’t force it if it resists.
2. Rinse It: Run it under warm water to dislodge debris. Use a soft brush (like an old toothbrush) for stubborn bits.
3. Check for Damage: Look for cracks or wear. A damaged filter should be replaced.
4. Reinstall: Place it back securely, ensuring it locks into position.
The Spruce recommends, “Clean your dishwasher filter every month or so—or sooner if you notice poor cleaning performance or odors.”[(( The Spruce ))]

Additional Tips for Dishwasher Maintenance
While you’re at it, consider these extras to keep your dishwasher in top shape:
- Scrape, Don’t Rinse: Filters work best when food scraps are scraped off plates rather than rinsed, which can clog the system unnecessarily.
- Run a Vinegar Cycle: Place a cup of white vinegar on the top rack and run a hot cycle monthly to break down grease and limescale.
- Inspect the Spray Arms: Clogged spray arm holes can reduce cleaning efficiency—clean them with a toothpick if needed.

Troubleshooting: What If You Can’t Find the Filter?
If you’ve searched the bottom of your dishwasher and still can’t spot the filter, consider these possibilities:
- Hidden Design: Some high-end models tuck filters behind panels or integrate them into the pump. Check your manual or the manufacturer’s website.
- No Filter: Rare, but older or budget models might rely on a basic trap instead of a proper filter.
- Professional Help: If all else fails, a technician can identify it for you.
