If your dishes come out with food bits still clinging on, or you’ve noticed a musty smell every time you open the dishwasher, the culprit is almost certainly a dirty filter. The filter traps food scraps, grease, and debris so they don’t recirculate onto your clean dishes. Over time, that buildup chokes the water flow and forces the dishwasher to work harder. The good news: cleaning a Frigidaire dishwasher filter takes less than ten minutes and requires no special skills.
Below you’ll find a complete, step‑by‑step guide written for 2026 – with current best practices, safety tips, and the exact details that separate an average cleaning job from one that keeps your dishwasher running like new for years.
Why Cleaning Your Dishwasher Filter Matters (More Than You Think)
A clogged filter doesn’t just leave spots on glasses. It also:
- Reduces water pressure – food‑packed mesh restricts the spray arms, so water can’t reach the top rack.
- Traps bacteria – damp, organic residue is a breeding ground for mold and mildew, causing that sour odor.
- Forces the pump to work harder – a restricted drain pump can burn out early, leading to costly repairs.
- Wastes energy – the machine runs longer cycles to compensate, bumping up your utility bill.
Frigidaire’s own owner‑support materials recommend checking the filter monthly, especially if you run the dishwasher more than once a day. A quick clean every four to six weeks is the sweet spot between “forgotten” and “overkill.”
Tools You Will Need
You probably already own everything. Gather these before you start so you don’t have to stop mid‑job.
| Tool | Purpose |
|---|---|
| Warm water | Rinses loose debris from the filter mesh |
| Soft‑bristled brush (old toothbrush works) | Scrubs stuck‑on particles without scratching |
| Mild dish soap or a homemade degreaser | Cuts through grease film – mix 1 tbsp baking soda with a few drops of liquid soap |
| Small bowl or container | Catches drips when you lift the filter out |
| Flashlight | Helps spot hidden blockages inside the filter housing |
| Towel | Keeps the dishwasher floor dry |
Optional but handy: a toothpick or wooden skewer to pick out stubborn bits lodged in the mesh. Never use metal tools – they can tear the screen.
Safety first: Unplug the dishwasher or trip the circuit breaker before reaching inside. Even with the unit off, water can be present near the drain area, so dry hands and a towel underneath are smart precautions.
If you need a gentle cleaning solution, consider the approach used for cookware – a mild scrub with baking soda works without scratching. For more detail, see our guide on the best way to clean aluminum pots and pans – the same avoid‑scratches rule applies here.
Locating the Filter in Your Frigidaire Dishwasher
Most Frigidaire models (including the popular FFBD, FGIP, and Gallery series) use a two‑piece filtration system: a coarse mesh cylinder (the “fine filter”) and a flat plastic strainer (the “coarse filter”). They sit together at the bottom center of the tub, directly under the lower spray arm.
Step 1: Open the dishwasher door fully. Remove the lower dish rack – slide it straight out and set it aside.
Step 2: At the bottom of the tub, look for a circular assembly about 3–4 inches wide. You’ll see a raised knob or handle in the center. That’s the filter housing.
Step 3: Use your flashlight to peek into the area around the housing. Some models have a small drain port nearby – check it for any visible blockage.
Step 4: Note whether your filter cover twists off or has a clip/latch. Most Frigidaire units use a quarter‑turn twist (counterclockwise to unlock). A few older models require a flat‑head screwdriver to release a spring clip.
Understanding the drainage setup can also help you troubleshoot if water pools under the filter. For a visual of how the dishwasher drain connects to your sink plumbing, see the plumbing under kitchen sink diagram with dishwasher – it shows where clogs often migrate from the filter to the garbage disposer.
Removing the Filter (Step‑by‑Step)
- Twist counterclockwise – grip the filter handle firmly and turn it to the left (about 45–90 degrees). You should feel it release.
- Lift straight up – the entire cylinder and strainer should come out together. A little water may spill – the bowl underneath catches that.
- Separate the two pieces – gently pull the mesh cylinder apart from the flat strainer. Some Frigidaire filters snap together; others have a twist lock between the pieces.
- Check the filter well – while the filter is out, shine your flashlight into the empty housing. Look for any stray food, a stray popcorn kernel, or a broken glass shard. Remove anything you see with your fingers or tweezers.
A common mistake: forcing the filter if it doesn’t twist easily. If it feels stuck, check for a clip you missed. Never yank – you can crack the plastic bayonet.
Cleaning the Filter Properly
This is where the real work happens. Water alone won’t remove the greasy film that builds up over time.
Rinse First
Hold both filter pieces under a stream of warm (not hot) tap water. Rotate them so every side gets hit. Most loose debris will fall away immediately.
Scrub Gently
Dip your toothbrush in warm, soapy water (or baking‑soda paste) and scrub the mesh cylinder in circular motions. Pay extra attention to the outer grooves where food tends to pack into a hard ring. Scrub the flat strainer on both sides – a surprising amount of slime clings to the underside.
Use Baking Soda for Grease
If the filter feels slippery or looks cloudy, make a paste of 2 tablespoons baking soda and enough water to form a spreadable consistency. Apply it with the brush, let it sit for 2 minutes, then rinse. This breaks down fatty residue without harsh chemicals.

Dry Thoroughly
Shake off excess water and pat the filter dry with a clean towel. Moisture left in the mesh can promote mold before you even reinstall it.
Inspecting for Damage
Before putting the filter back, give it a close look. A damaged filter is worse than a dirty one because it lets food bypass into the pump.
- Check for cracks in the plastic housing – especially around the twist tabs.
- Look for tears in the stainless‑steel or nylon mesh. Even a pinhole tear can let sand‑sized particles through.
- Examine the rubber gasket (if present) – it should be pliable, not brittle.
- Warping? If the filter doesn’t lie flat, it won’t seal properly.
When to replace: If you see any cracks, tears, or warping, order a genuine Frigidaire replacement filter. Using a damaged filter will eventually force you to deal with a clogged drain hose or a burned‑out pump motor – repairs that cost ten times the price of a new filter.
Reinstalling the Filter
- Reassemble the two pieces – click or twist them together so they’re flush.
- Align the filter – lower it into the housing so the tabs match the slots.
- Press down and twist clockwise – a gentle push downward while turning will lock it into place. You should hear or feel a click.
- Test for stability – give the handle a slight wiggle. It should not move or rattle. If it feels loose, twist a little further.
Avoid overtightening – you only need enough rotation to seat the filter. Twisting too hard can strip the plastic threads.
Maintenance Tips and Schedule
- Monthly cleaning is ideal for average households (4–6 loads per week). If you have a large family or run the dishwasher daily, bump it to every two weeks.
- Rinse the filter after heavy‑soil loads – if you just washed a casserole dish with baked‑on cheese, give the filter a quick rinse even if it’s not “cleaning day.”
- Clean the spray arms at the same time – food bits can clog the spray arm holes. Pop them off (they usually snap or twist) and run water through them.
- Keep the door ajar after cycles – this dries out the interior and reduces mold growth on the filter.
While you’re in the habit of cleaning kitchen appliances, consider tackling the surfaces around the dishwasher. A clean environment helps keep airborne grease off the filter. For tips on maintaining another frequently used surface, check out how to clean a black cooktop without scratching.
Frequently Asked Questions
Q: How often should I clean the Frigidaire dishwasher filter?
Once a month is standard. If you notice a smell or cloudy dishes sooner, clean it immediately.
Q: Can I run the dishwasher without the filter?
No. The filter protects the drain pump and recirculation system. Running without it can suck food particles into the pump, causing noise, leaks, or pump failure.
Q: Why is water pooling in the bottom of my dishwasher after a cycle?
A clogged filter is the most common cause. Remove and clean the filter. If water still pools, check the drain hose and the air gap (if you have one) – often a blocked air gap mimics a dirty filter.
Q: My filter still smells after cleaning – what now?
Soak the filter in a solution of 1 part white vinegar and 3 parts warm water for 30 minutes. Rinse well. This kills odor‑causing bacteria. Also wipe down the filter housing inside the tub.
Q: Do all Frigidaire dishwashers have the same filter?
Most newer models (2016–2026) share the same two‑piece design. However, a few built‑in models use a self‑cleaning filter that requires manual removal only once or twice a year. Check your owner’s manual – or look for a small pull‑out handle at the bottom front – to be sure.
Conclusion
Cleaning a Frigidaire dishwasher filter is a simple ten‑minute task that pays off in spotless dishes, fresher smells, and a longer‑lasting machine. By making it part of your monthly routine – and inspecting the filter for damage as you go – you avoid expensive repairs and keep your appliance running at peak efficiency into 2026 and beyond.
Your next step: Set a recurring reminder on your phone for the first Saturday of every month. Grab your brush, spend ten minutes, and enjoy dishes that actually shine. If you prefer a visual walk‑through, Frigidaire’s official support site offers video demonstrations for specific model numbers.
