You brought home a dishwasher so you’d never have to hand-wash a plate again, right? Good news: your dishwasher isn’t dying. Better news: a five-minute filter clean will probably fix those cloudy glasses and that weird lingering scent of “taco night” from three days ago. Let’s turn your appliance from a swampy mess back into the high-performance machine it’s meant to be.
Watch this short video to learn how to deep clean a dishwasher filter:
Know Your Dishwasher Filter (So You Don’t Accidentally Sabotage It)
The dishwasher filter cleaning process is the single most important bit of maintenance you can do. Think of the filter as the “security guard” of your appliance—it catches food particles so they don’t recirculate back onto your dishes or clog your pump.
If you ignore it, that trapped gunk starts to rot, leading to smells and “redeposit” (that annoying sand-like grit on your plates). Most modern machines use manual filters. Key vibe check:
- Location: Usually at the bottom of the tub, under the bottom rack.
- Type: Most are “twist-and-pull” cylinders.
- The Risk: If you ignore it, you’re basically washing your dishes in old food soup. Hard pass.
Cleaning Hacks That Prevent Funky Smells and Cloudy Dishes
Most dishwasher drama comes from simple buildup. You don’t need a degree in engineering; you just need to know how to handle the hardware.
The Quick Visual Check (Plus One Upgrade)
Pull out the bottom rack and look at the floor of the dishwasher. If you see standing water, slimy buildup, or visible chunks of food around the center plastic hub, it’s time.
- The Upgrade: Use a flashlight to peek into the filter housing once the cylinder is out. If you see a stray cherry pit or a piece of glass down there, fish it out (carefully!).
The Right Way to Rinse (No Damage)
Take your filter to the sink. 90% of the time, a warm water rinse is all it needs.
- Soft brush only: Use an old toothbrush or a soft dish brush.
- What NOT to use: Never use a wire brush or a scouring pad. The mesh is delicate; if you poke a hole in it, you’re letting pump-destroying debris through.
Deep Clean When It’s Really Gross
If the mesh is clouded with white calcium scale or greasy film, a rinse won’t cut it.
- The Soak: Fill a bowl with warm water, a squirt of dish soap, and a cup of white vinegar. Let the filter sit for 10 minutes. The grime will slide right off.
Build a Cleaning Rhythm That Actually Sticks
How often you clean depends on how much you “pre-rinse.”
- The “Scrape and Go” crowd: Clean the filter once a month.
- The “Pre-Washers”: You can get away with once every three months.
- Pro Tip: Set a recurring phone reminder. Waiting until the dishwasher smells like a dumpster means you’ve waited too long.
Filter Type and Dishwasher Model: The Secret Sauce
Consulting a dishwasher filter guide is vital because every brand has a slightly different “handshake” to get the filter out. Forcing it can snap the plastic tabs, which is a pricey mistake.
Manual Filters vs. Self-Cleaning Filters
- Manual: You have to pull it out and rinse it. They are much quieter.
- Self-Cleaning: These have a “macerator” (basically a tiny garbage disposal). They are louder and rarely need maintenance, but if the dishwasher isn’t draining, the internal grinder might be jammed.
Reinstalling Correctly (Don’t Skip This)
When you put the filter back, make sure it “clicks” or locks into place.
- The Danger: A loose filter can float up during a cycle, allowing debris to fly into the pump. That’s a $300 repair for a 0-cent mistake.
Brand-Specific Cleaning Tweaks That Save Time
How to Clean Maytag Dishwasher Filter
Maytag is built for heavy-duty loads, which means more grease buildup. If your Maytag has a manual filter, it often requires a firm twist. Check the “sump” (the hole where the filter goes) for large debris while the filter is out.
How to Clean Samsung Dishwasher Filter
Samsung filters are usually located in the front-left or center-bottom of the tub.
- The “Fine Filter”: Turn the handle counterclockwise to unlock.
- The “Micro Filter”: Many Samsung models have a secondary flat mesh screen. Lift it out and check the underside—Samsung’s high-efficiency designs can sometimes trap fine silt here that causes cloudy spotting. Reassemble by aligning the arrows until you hear a definitive “click.”
How to Clean KitchenAid Dishwasher Filter
KitchenAid usually features a circular triple-filter system. Turn the upper filter assembly a quarter-turn counterclockwise to lift it out. There’s often a flat “lower filter” sitting underneath it—don’t forget to rinse the bottom of that as well.
How to Clean Whirlpool Dishwasher Filter
Whirlpool filters are very similar to KitchenAid. Look for arrows on the filter and the floor of the dishwasher. When you reinstall, align those arrows perfectly, or the spray arm might hit the filter.
How to Clean GE Dishwasher Filter
GE models often have a “Fine Filter” (the cylinder) and a “Large Object Trap.” Some GE models have a screw-in filter rather than a twist-lock. If it doesn’t budge with a gentle twist, check for a small screw holding it in place.
Common Problems and Fast Fixes
- Smelly dishwasher: Clean the filter, then run an empty cycle with a bowl of vinegar on the top rack.
- Grit left on dishes: Your filter is likely full or not seated correctly.
- Standing water: The filter or the drain hose is clogged. Check the filter first!
- Filter looks clean but dishes aren’t: Check your spray arms. The tiny holes might be clogged with hard water deposits.
Bonus Habits That Make a Big Difference
- Scrape, don’t rinse: Your dishwasher detergent actually needs a little grease to cling to, but it doesn’t need the whole leftover dinner.
- Run hot water first: Run the kitchen sink until the water is hot before starting the dishwasher. This ensures the first fill is hot enough to melt grease immediately.
- Leave the door cracked: After the cycle ends, propping the door open for 20 minutes prevents that “damp basement” smell.
- Don’t ignore spray arms: Once a year, poke a toothpick into the spray arm holes to clear out mineral scale.
FAQs
How often should I clean my dishwasher filter?
Once a month is the gold standard for most households. If you only run it once or twice a week, every three months is fine.
Where is the dishwasher filter located?
At the very bottom of the tub, usually tucked under the bottom spray arm. You’ll see a circular plastic handle or mesh cylinder.
Can I run the dishwasher without the filter?
No. Never. This is a fast track to a broken drain pump and a very expensive repair bill.
Why does it still smell after cleaning?
Check the rubber door seal (the gasket). Food gunk often hides in the folds of the rubber where the filter cleaning won’t reach. A quick wipe with vinegar usually solves this.
Do all dishwashers have removable filters?
Most modern ones do. If your dishwasher is very loud and more than 15 years old, it might have a self-cleaning macerator (grinder) instead.
Closing Thoughts
Your dishwasher is a workhorse, but it isn’t a magician. A clean filter is the difference between sparkling wine glasses and a gritty mess. It takes less time than making a cup of coffee, but it adds years to your appliance’s life. Keep it clear, lock it in tight, and let the machine do the heavy lifting for you.
