What Does the Dishwasher Filter Do?
The dishwasher filter is a small but mighty part of the appliance, typically located at the bottom of the machine. Its primary job is to catch food scraps, grease, and other debris during the wash cycle, preventing them from clogging the drain or redepositing onto your dishes. Some dishwashers have self-cleaning filters that grind up debris, while others feature manual filters that require regular cleaning. Knowing your dishwasher’s type is the first step to determining its maintenance needs.

How Often Should You Clean Your Dishwasher Filter?
The general recommendation from experts and manufacturers is to clean your dishwasher filter every 1 to 3 months, depending on usage and the type of filter. However, this can vary based on several factors. Here’s what the pros say:
- Manufacturer Guidelines: According to Whirlpool, a leading appliance brand, “Check and clean your dishwasher filter every three to four months—or more often if you notice residue buildup or odors.” They emphasize that regular maintenance extends the life of the appliance [(Whirlpool: How to Clean a Dishwasher Filter)].
- Usage Frequency: If you run your dishwasher daily or have a large household, food debris accumulates faster. Sarah Fishburne, director of trend and design at The Home Depot, suggests checking the filter monthly in busy kitchens to avoid performance issues.
- Type of Filter: Dishwashers with manual filters need more frequent attention than those with self-cleaning systems. GE Appliances notes, “For models with a manual filter, inspect it every month and clean as needed. Self-cleaning filters may only need a check every six months unless you notice problems” [(GE Appliances: Dishwasher Filter Cleaning Guide)].
In short, a good rule of thumb is to inspect the filter monthly and clean it if you see visible buildup. If your dishwasher is lightly used, stretching it to every three months might suffice.

Factors That Affect Cleaning Frequency
Several variables can influence how often your filter needs attention. Here’s a deeper look:
1. Household Size and Cooking Habits: A family of five cooking heavy, greasy meals will generate more debris than a single person heating up leftovers. The more food scraps your dishwasher handles, the quicker the filter clogs.
2. Pre-Rinsing Practices: Do you rinse your dishes before loading them? Skipping this step means more particles end up in the filter. While modern dishwashers are designed to handle some scraps, excessive buildup can strain the system.
3. Water Hardness: Hard water leaves mineral deposits that can coat the filter over time. If you live in an area with high mineral content, you might need to clean the filter more often to prevent clogs.
4. Detergent Type: Using low-quality detergent or overloading detergent can leave residue that sticks to the filter. Experts recommend using the manufacturer-recommended amount to minimize buildup.

How to Tell If Your Filter Needs Cleaning
You don’t always have to stick to a strict schedule—your dishwasher will give you clues when it’s time to clean the filter. Watch for these signs:
- Funky Odors: A smelly dishwasher often means trapped food is rotting in the filter.
- Dirty Dishes: If your plates come out with grit or spots, the filter might be blocked, preventing proper water circulation.
- Standing Water: Puddles at the bottom after a cycle suggest a clogged filter or drain.
- Unusual Noises: Grinding or rattling could indicate debris stuck in the filter or pump.
If you spot any of these, it’s time to roll up your sleeves and check the filter—no need to wait for the three-month mark.

Step-by-Step Guide to Cleaning Your Dishwasher Filter
Cleaning the filter is a straightforward task that takes about 10 minutes. Here’s how to do it, based on advice from Good Housekeeping:
1. Turn Off the Dishwasher: Unplug it or switch off the power at the breaker for safety.
2. Locate the Filter: Remove the bottom rack and look for a cylindrical or flat filter at the base. Check your manual if you’re unsure.
3. Remove the Filter: Twist or pull it out (some models have a locking mechanism—refer to your owner’s manual).
4. Clean It: Rinse under warm water and use a soft brush or sponge to scrub off debris. For stubborn grease, soak it in warm, soapy water for 5-10 minutes.
5. Inspect the Area: Wipe down the filter housing with a damp cloth to remove any stray gunk.
6. Reinstall: Pop the filter back in place, ensuring it’s secure.
7. Run a Test Cycle: Use a rinse cycle with vinegar to flush out any remaining residue [(Good Housekeeping: How to Clean Your Dishwasher)].

Extra Maintenance Tips for a Healthy Dishwasher
Cleaning the filter is just one part of dishwasher care. Here are some bonus tips to keep it performing at its best:
- Run a Vinegar Cycle: Once a month, place a cup of white vinegar on the top rack and run a hot cycle to break down grease and limescale.
- Wipe the Door Seals: Food and moisture can collect in the rubber gasket—clean it with a damp cloth weekly.
- Check the Spray Arms: Clogged holes can reduce cleaning power. Remove and rinse them if needed.
- Use a Dishwasher Cleaner: Products like Affresh or Finish Dishwasher Cleaner (available at most retailers) tackle hidden grime every few months.

Common Mistakes to Avoid
Even with good intentions, it’s easy to slip up. Here’s what not to do:
- Ignoring the Manual: Every dishwasher is different—skipping the manufacturer’s instructions can lead to improper cleaning or damage.
- Using Harsh Tools: Metal scrubbers or knives can scratch the filter, creating spots for bacteria to grow.
- Overlooking Small Debris: Tiny bones or seeds can slip through and clog the pump if not fully removed.

FAQ: Your Dishwasher Filter Questions Answered
Q: Can I skip cleaning the filter if my dishwasher has a garbage disposal feature?
A: Not entirely. Self-cleaning filters grind larger debris, but grease and small particles can still build up. Check it every six months or if you notice issues.
Q: How long does a dishwasher filter last?
A: Filters don’t typically need replacing unless damaged. With proper care, they last the life of the appliance.
Q: What happens if I don’t clean the filter?
A: Over time, a dirty filter can cause poor cleaning, bad smells, and even pump failure, leading to costly repairs.
Q: Can I put the filter in the dishwasher to clean it?
A: No—clean it by hand. Dishwasher cycles won’t remove trapped debris effectively and could damage the filter.
Q: Is it normal for the filter to smell bad?
A: A slight odor from food buildup is common, but a strong stench means it’s overdue for a cleaning.
