How to Clean Frigidaire Dishwasher Filter the Right Way (Expert Tips)

Last week, I noticed my Frigidaire dishwasher wasn’t cleaning dishes as well as before. Some cups came out cloudy, and there was a faint odor inside. I thought maybe the detergent wasn’t doing its job, but the real culprit was the dirty filter. It’s something most people forget to clean, yet it makes a huge difference. In this article, I’ll show you exactly how to clean Frigidaire dishwasher filter in simple, easy steps.

1. Locate the bottom of the dishwasher where the filter sits.
2. Remove the lower rack carefully to access the filter area.
3. Twist the filter counterclockwise to unlock and lift it out.
4. Wash it under warm water using mild soap and a soft brush.
5. Rinse thoroughly and check for any leftover debris.
6. Reinstall the clean filter by twisting it clockwise until snug.

Find the Filter Location in Your Frigidaire Dishwasher

Before you start, the first thing is to know exactly where your dishwasher filter is located. In most Frigidaire dishwashers, it sits right under the bottom spray arm. You’ll usually see a round or cylindrical piece that looks like a small cap or mesh cover. Once you know where to look, it becomes an easy job that only takes a few minutes.

Start by pulling out the bottom rack to make enough room. Many people forget this step and struggle to reach the filter properly. When you pull the rack out, it gives you a clear view of the filter area. If you notice bits of food or soap residue down there, that’s already a sign it needs a good cleaning.

Sometimes, the filter can be hidden under another cover or spray arm, depending on the model. So, check your manual or look around for a locking ring. It’s simple once you spot it. You’ll know it’s the right piece when it moves slightly when twisted. Once located, you can move on to removing it.

Having the correct spot identified makes the whole process smoother. If you’re not sure, shine a flashlight inside for better visibility. Also, make sure the dishwasher is turned off and cool before you begin. No one likes to work in a hot, damp appliance, right?

• Filter usually at bottom under spray arm
• Remove lower rack for better access
• Use flashlight if visibility is low
• Make sure dishwasher is off and cool

Remove the Filter Gently Without Damaging It

Now that you’ve found the filter, it’s time to remove it carefully. This part is easy but must be done with a bit of care. The filter is made of fine mesh and plastic, which can break if you twist too hard. Gently turn it counterclockwise to unlock it. You’ll feel it loosen, and then you can lift it right out.

If it feels stuck, don’t force it. Sometimes debris or soap residue can make it hard to move. Try wiggling it lightly while turning. Once it pops free, lift it straight up. Inside, you might find small food particles or even bits of glass from broken dishes — it happens more often than you’d think.

Put the removed filter on a towel or sink area. You’ll probably notice grime buildup, and that’s okay. This dirt is exactly what keeps your dishwasher from clogging or draining slowly. Taking it out regularly keeps your appliance working efficiently and odor-free.

Before washing it, check for any cracks or damage. A broken filter can’t do its job properly. If it’s damaged, you can buy a replacement online or from a local store — they’re not expensive. But if it’s fine, you’re ready to clean it up.

• Turn counterclockwise to unlock
• Avoid forcing if it feels tight
• Check for cracks or residue
• Set aside on towel for cleaning

Clean the Filter Using Soap and Warm Water

This is where the magic happens. Take your dirty filter to the sink and rinse it under warm running water. Use mild dish soap and a soft brush, like an old toothbrush, to gently scrub off debris. Don’t use anything sharp because the mesh can tear easily. It’s better to take your time and do it slowly.

You’ll see how much grime comes off, especially if you haven’t cleaned it for months. Sometimes greasy residue sticks stubbornly, so soak it in warm soapy water for about 10 minutes. This loosens up everything and makes brushing easier. A clean filter lets water flow better and improves washing results.

While you clean, look closely at the mesh screen. If you notice any hard buildup, use a toothpick or soft brush to remove it. Avoid bleach or harsh chemicals — they can damage the plastic. Just regular soap and warm water are more than enough.

Once it looks clean, give it one last rinse. Hold it under running water and make sure there’s no soap left. You’ll be surprised how fresh it smells now, especially compared to when you first pulled it out. It’s a small task that makes a big difference in your dishwasher’s performance.

• Use warm water and mild soap
• Scrub gently with soft brush
• Avoid harsh chemicals or sharp tools
• Rinse thoroughly after cleaning

Inspect and Clean the Filter Housing Area

After cleaning the filter, don’t forget the spot it came from — the filter housing. Many people skip this part, but it’s just as important. Food particles and grease often get stuck down there. If left unchecked, they can cause odors or even drainage issues. So take a minute to wipe it out.

Use a damp cloth or sponge to clean inside the housing. If you see hard buildup or residue, use a small brush to scrub lightly. Make sure to remove any leftover gunk or soap scum. It’s usually hidden near the edges, so check carefully.

If your dishwasher smells bad, this is often where the problem starts. Cleaning this area keeps your machine fresh. You can also run a quick rinse cycle later with vinegar to remove any leftover odor. That’s an easy trick I’ve learned from experience.

Once everything looks spotless, dry the area with a towel. It doesn’t have to be perfect, just free from visible debris. Now you’re ready to reinstall the clean filter and get things running again.

• Wipe the housing area clean
• Use brush for stubborn buildup
• Clean edges and corners
• Optional: run vinegar rinse for freshness

Reinstall the Filter Properly and Secure It

Now it’s time to put your filter back. Make sure it’s completely dry before reinstalling. Set it into the slot gently and turn it clockwise until you feel it lock in place. It shouldn’t wobble or move loosely. A snug fit means it’s properly sealed and ready to go.

Sometimes, people place it incorrectly, causing drainage problems later. So double-check that the arrows or marks (if any) are aligned. The locking motion should be smooth, not forced. Once in, try spinning it lightly — if it stays firm, it’s secure.

Slide the bottom rack back in and check if it moves freely. You don’t want anything touching the filter or interfering with the spray arm. It’s a small detail but helps ensure everything runs smoothly during the wash cycle.

Finally, wipe down the inside of the door and the gasket area. Now your dishwasher is ready for action again. A clean filter keeps your dishes spotless and your dishwasher running longer. Feels good, doesn’t it?

• Dry filter before reinstalling
• Lock by turning clockwise
• Check for snug fit
• Ensure no parts are obstructing it

Maintain and Keep the Filter Clean Regularly

Now that your Frigidaire dishwasher filter is sparkling clean, keeping it that way is simple. Make a small habit of checking it every month. It only takes five minutes but saves you from bigger problems later. Consistent cleaning prevents odors, clogging, and poor wash results.

If you cook often or use your dishwasher daily, clean it more frequently. Greasy dishes or leftover food can clog the filter faster. I like to give mine a quick rinse whenever I see cloudy dishes or a funny smell. Those are signs it needs attention.

You can also run a dishwasher cleaner tablet once a month to help dissolve hidden grease. It’s a great way to keep the inside fresh without extra effort. And always scrape off big food bits before loading dishes — it helps your filter last longer.

Think of it like routine car maintenance — a little effort regularly keeps everything working perfectly. Your dishwasher deserves the same care. So stay consistent, and you’ll notice cleaner dishes and a smoother-running appliance every time.

• Clean filter monthly
• Remove food bits before washing
• Use cleaning tablets occasionally
• Check for odors or residue regularly

Final Thoughts

Cleaning your Frigidaire dishwasher filter is one of those tiny jobs that make a big impact. It’s quick, easy, and keeps your dishes spotless every time. Regular cleaning also prevents damage and odors. With just a few minutes of care, your dishwasher stays strong, efficient, and ready to handle everyday messes.

Frequently Asked Questions (FAQs)

Is it necessary to clean my Frigidaire dishwasher filter regularly?

Yes, it’s absolutely necessary. Over time, food particles, grease, and detergent residue collect on the filter. This buildup can cause poor water drainage, unpleasant smells, and even cloudy dishes. Cleaning it monthly ensures your dishwasher runs efficiently. It’s just like changing oil in a car — simple maintenance that prevents bigger issues later. Plus, it helps extend your dishwasher’s lifespan.

Can I clean the filter without removing it?

Technically, you can rinse around it, but that won’t clean it properly. The real dirt hides underneath and in the mesh. Removing it gives you full access to wash away all grime and buildup. It only takes a minute or two, and you’ll see much better results. Think of it as deep cleaning instead of just wiping the surface.

Do I need special tools to clean the filter?

Not at all. You only need warm water, mild soap, and a soft brush or old toothbrush. Avoid sharp tools or harsh chemicals, as they can damage the mesh or plastic. Sometimes, soaking it for a few minutes helps loosen stubborn grease. It’s all about gentle care, not force. Keep it simple, and it’ll work perfectly.

Can a dirty filter cause my dishwasher to smell?

Yes, a dirty filter is one of the most common causes of bad odors in dishwashers. Food particles trapped inside start to decompose over time, creating a sour smell. Cleaning the filter removes these residues instantly. For an extra boost, run an empty cycle with vinegar once a month — it keeps your dishwasher smelling fresh.

Is it okay to use bleach to clean the filter?

It’s better not to. Bleach can damage the filter’s plastic and mesh material. Instead, use mild dish soap or white vinegar. Both are safe and effective for removing grime and grease. Bleach is too harsh for these parts, and over time, it can weaken them. Gentle cleaning products always work best for dishwasher care.

Can I put the filter in the dishwasher to clean it?

No, you shouldn’t. The heat and water pressure inside a dishwasher can damage the delicate filter mesh. Always wash it by hand using warm, soapy water. It takes just a few minutes and ensures it stays in good shape. Treat it gently — it’s a small part but an important one for your machine’s performance.

Do I need to dry the filter before reinstalling it?

Yes, drying is a good idea. A quick wipe with a clean towel prevents water spots or soap residue from dripping back inside. It also helps you check for cracks or damage before reinstalling. Just make sure it’s snug and locked properly when you put it back. A dry, clean filter works best every time.

Can a dirty filter affect my dishwasher’s performance?

Definitely. When the filter is clogged, water can’t circulate properly, leading to dirty dishes, poor drainage, and even strange noises. Cleaning it restores normal water flow and ensures powerful cleaning action. It’s one of the simplest ways to keep your dishwasher performing like new. Just a few minutes of cleaning make a huge difference.
