How to Clean a Frigidaire Dishwasher Filter in 5 Minutes Flat

If your dishes are coming out filmy, and the bottom of the tub smells faintly of a swamp, you already know something’s off. Most the majority blame the detergent or the rinse aid. I’ve learned the hard way that the biggest culprit is the one part almost nobody checks: the filter. Figuring out how to clean a Frigidaire dishwasher filter isn’t complicated, but skipping it'll ruin wash performance and eventually wreck the drain pump.

TL; DR

• Clean the filter once a month; switch to every two weeks if you don’t pre-rinse dishes, because trapped food turns into a slimy, odor-producing mess.
• You need only a soft brush, warm soapy water, and 5 minutes—never use wire brushes that poke holes in the fine mesh.
• After cleaning, always inspect the sump for glass shards or toothpicks that can jam the pump; then lock the filter until it clicks.

Key Takeaways

• According to senior appliance technician James Robinson, a clogged filter is the number one reason dishwashers stop cleaning effectively.
• You’ll extend the drain pump’s life by reducing strain, which saves you $150–$300 in repair calls for “not draining” issues.
• The filter assembly has a cylindrical fine mesh and a coarse plastic guard—both must be separated and rinsed.
• Incorrect reinstallation (no click) lets debris bypass the filter and directly enter the motor, which can cause irreversible damage.
• If you neglect the filter for months, it becomes so slimy and gross that you’ll wish you’d done this earlier. Happened to me once—never again.

What You’ll Need

By most accounts, here’s what you want on hand before you start. No special apps required. Just stuff you already have under the sink.

• Soft nylon brush or an old toothbrush: The mesh is delicate. Stiff or wire bristles will tear it.
• Mild dish soap: Anything as gentle as Dawn or Seventh Generation works. Stay away from abrasive cleaners.
• Warm water: Hot enough to cut grease but not scalding.
• A towel or rag: The process can be drippy, especially if your filter’s been sitting in standing water.
• Time: about 5 minutes from start to finish, maybe 10 if it’s your first attempt.
• Skill level: Absolute beginner. If you can unscrew a jar lid, you can do this.

When you look closely, actually, let me put that more precisely. The one thing I wish I’d had the first time is a pair of thin rubber gloves. The filter gets coated in a gray, gelatinous film that’s basically decaying food; it’s not dangerous, but it’s unpleasant. Just saying.

Step 1: Locate the Filter Assembly at the Bottom of the Tub

By most accounts, open the door, and pull out the lower dish rack. As it turns out, right in the center. Or slightly to the side (and rightly so) of the sump area. A striking point.

You’ll spot a cylindrical plastic piece sticking up an inch or two. That’s the filter assembly. In most Frigidaire models, the whole unit consists of a round fine-mesh filter and a flat coarse filter stacked together. Surprising, not really.

If you’ve rarely ever noticed it before. You’re not alone, I overlooked mine for six months. After moving into a new place.

Why does my dishwasher even have a filter if I scrape plates first?

Going back to what was covered earlier, here's the reality — because even after scraping, tiny food particles, grease, and paper from labels wash off dishes, and honestly, the filter catches these bits so they don’t recirculate onto your glasses. Over time, the mesh clogs, and the pump has to work harder. You end up with gritty residue all over what should be clean dishes.

Step 2: Remove the Filter by Turning It Counter-Clockwise

In practical terms, grip the cylindrical top and give it a gentle quarter-turn counter-clockwise, and you’ll feel it really; then lift the whole assembly straight out. On some units, the coarse flat filter stays in place. In most cases, the first time I tried this, I twisted too aggressively, and almost snapped a plastic tab—so ease up if it feels stuck. If the filter doesn’t budge. Sloshing some warm water around the base loosens the gunk that’s cementing it in.

Which is to say, the real risk here isn’t the cleaning itself — it’s cracking the plastic by treating it like a stubborn pickle jar. Go slow.

Step 3: How to Clean the Frigidaire Dishwasher Filter Properly

This reflects what I mentioned a while ago. Separate the fine mesh cylinder from the coarse plastic guard. Most of the time they just pull apart; occasionally you twist the inner piece first, and once both, wait. Let me rephrase, parts are separated, hold them under warm running water and use your soft brush to scrub every surface. Pay special attention to the inner mesh, where greasy biofilm hides.

Work from the inside out so you’re not pushing debris deeper. Rinse until the water runs clear.

I once tried using a sponge, and ended up rubbing more sludge in than out. Don’t do that. Which is why you need the friction of a brush to break apart the oily layer that clings to the mesh. If the filter still smells after scrubbing, soak it in a 1:1 mix of warm water and white vinegar for 10 minutes, then brush again.

That lifts the stubborn stuff.

Can I use a dishwasher cleaner tablet instead of manual scrubbing?

In practice, no, and this is a hill I’ll die on. A notable twist. Home maintenance specialist Sarah Miller puts it bluntly. “Never use a dishwasher cleaner tablet as a substitute for manual filter cleaning. You've to get your hands dirty.

Step 4: Inspect the Sump for Hidden Debris

Then again, with the filter removed, you’ll see the sump. The small pit where the drain pump inlet lives. Plus, shine a flashlight in there.

More importantly, look for glass shards, toothpicks, bones. Or pieces of plastic wrap that (at least in quite a few practical scenarios) slipped past the filter. I once found a grape stem that had lodged perfectly across the drain opening…which means causing water to pool after every cycle.

Use a pair of tweezers. Or a wet-dry vac attachment to fish out anything that doesn’t belong. Skip this step, and you might reinstall a clean filter only to have the pump jam on debris that was already there.

Step 5: Reassemble and Lock the Filter Until It Clicks

Now put everything back together. Slide the cleaned coarse filter into place first, then lower the fine mesh cylinder onto it, look for the alignment arrows on both pieces; they need to match up.

Once they’re aligned, press down and turn the assembly clockwise; you’ll hear a distinct click when it locks.

That click is everything. If you don’t hear it, the filter can float up during a wash cycle, and let food particles blast directly onto your plates again, defeating the whole purpose.

What’s the single biggest mistake people make after cleaning the filter?

They line up the arrows, but don’t twist far enough to engage the locking mechanism. What this means is unscrewed but seated looks fine—until the machine fills with water.

The whole filter assembly floats up. Then you get a wash full of debris, and a cleaner that’s pointless. Trust me, I’ve done it.

Troubleshooting Common Mistakes

Even if you follow every step, stuff goes sideways sometimes, and here's a speedy rundown of fixes for the stuff I see most (and have experienced myself).

• Filter still smells bad after scrubbing: You likely missed the underside of the coarse guard or the rubber gasket around the sump. Wipe both with a vinegar-soaked cloth and they’ll stop stinking. The gasket traps moisture and mold that the filter alone doesn’t.
• Cloudy glasses persist after cleaning: Check your dishwasher’s rinse aid level and water temperature. Hard water leaves a film that looks like food residue. Incoming water should be at least 120°F for the detergent to dissolve properly.
• Filter won’t come out at all: Years of neglect can cement the filter in place with baked-on sludge. Pour a cup of hot water mixed with a tablespoon of dish soap into the sump, wait 15 minutes, then try again. That usually softens the gunk enough to release it.
• You hear a clicking or grinding noise after reassembly: Something’s stuck in the sump or you didn’t lock the filter fully. Remove and recheck; a small piece of glass could be the culprit—it happened to a neighbor of mine and they ended up replacing the entire pump.

People Also Ask

How often should I clean my Frigidaire dishwasher filter?

Most likely if you skip pre-rinsing, bump it up to every two weeks. Because more food particles accumulate. Neglect it longer and you’ll start smelling that swampy odor.

What happens if I don’t clean the dishwasher filter for a long time?

The mesh clogs completely, causing water, I mean, to drain slowly or not at all. Dirty water recirculates; leaving grit on dishes, and the drain pump works under extra load, which can lead to a $200+ repair. Worth pausing on that one; eventually, the filter itself can get so gunky that it’s easier to replace it than scrub it.

Can I run the dishwasher without the filter in place?

100% not. The filter prevents large particles from entering, and destroying the pump. Now, plus, if run without it, food chunks and broken glass can lodge in the drain motor. Causing expensive damage that’s not covered under warranty usually.

Should I use soap or vinegar to clean the filter?

Taking a different approach here, mild dish soap and warm water are enough — a quick vinegar soak helps deodorize and break down mineral deposits. But never use bleach or harsh cleaners. They can degrade the plastic over time and damage the mesh.

Why do my dishes have white film even after cleaning the filter?

In most scenarios, white film is all the time challenging-water buildup, not food residue. A filter clean solves the gritty texture, but mineral film needs a rinse aid. Or a dishwasher cleaner (and rightly so) designed for limescale. Makes you think, doesn't it?, and check your water hardness; if it’s above 7 grains per gallon, install a softener or use a booster.

Is the filter cleaning process the same for all Frigidaire models?

Most models from the last decade use a similar twist-out cylindrical filter. But some older units have a square or removable screen. Consult your model’s manual if the cylinder isn’t obvious. The general cleaning technique remains the same.

What to Do Next

Here's the reality — once your filter is clean. And locked, you’ll notice an immediate improvement—glasses sparkle, the machine drains faster. And that musty smell vanishes. This isn’t a one-and-done task, it’s a habit.
