Is your Frigidaire dishwasher beginning to smell strange, or isn’t cleaning as well as before? Don’t worry—you’re not the only one. Many people who own homes forget that dishwashers also need to be cleaned. Even the best brands, such as Frigidaire, can accumulate grease, food scraps, and dirt over time. But here’s the good part. Learning how to clean Frigidaire dishwasher properly can make it feel brand new again. If you have cloudy glasses, a bad smell, or slow drains, this guide can help you. We’ll guide you through each step—from the filter to the spray arms—without using complicated terms. Put on your gloves, and let’s make that dishwasher shine again.

Why You Should Clean Your Frigidaire Dishwasher Regularly

It Doesn’t Clean Itself—Despite What People Think

It’s easy to assume your dishwasher stays clean because it’s constantly spraying hot water. However, in reality, grease, grime, and leftover food particles accumulate in the filter, spray arms, and even on the door seals. Over time, this creates the perfect environment for bacteria and mold to grow—and they can make your dishwasher smell horrible.

Dirty Dishwashers = Dirty Dishes

When your Frigidaire dishwasher isn’t cleaned regularly, you’ll start noticing signs like cloudy glassware, greasy plates, or bits of food stuck after a complete cycle. This happens because clogged filters and blocked spray arms prevent water from reaching all areas during the wash. A clean dishwasher equals clean dishes—simply put.

Regular Cleaning Boosts Performance and Saves Energy

When everything is running smoothly—filters clear, spray arms free, interior walls free from residue—your dishwasher doesn’t have to work as hard. This results in shorter wash times, improved water flow, and lower electricity consumption. It can even lower your utility bill over time.

It Protects Your Appliance Investment

Frigidaire dishwashers are built to last, but neglecting their proper care can cause them to wear out more quickly. Mold, rust, and minerals can damage items over time. Regular cleaning can help you avoid expensive repairs and prolong the life of your machine.

Essential Supplies You’ll Need Before You Start

Before we start the steps, let’s check that you have everything you need. You don’t need fancy products or expensive tools—just a few reliable items that you likely already have at home. When learning how to clean Frigidaire dishwasher, having the right supplies makes the job easier, quicker, and much more effective.

Basic Cleaning Supplies You Probably Have

• White vinegar – A natural deodorizer and mild cleaner that cuts through grease and grime.
• Baking soda – Perfect for scrubbing and eliminating odors.
• Dish soap – Go for a mild, non-abrasive liquid detergent.
• Old toothbrush or soft-bristle brush – Helps reach tight corners and scrub filters.
• Sponge or microfiber cloth – Ideal for wiping interior surfaces.
• Toothpicks or skewers – Useful for clearing out tiny holes in spray arms.

Optional But Helpful Tools

• Frigidaire ReadyClean™ cleaner – Specifically designed for Frigidaire dishwashers, safe and effective.
• Bottle brush – Good for reaching deep into parts like the spray arms or filter cylinder.
• Rubber gloves – To protect your hands during the scrubbing process.
• Paper towels or dry cloths – For drying out wet areas once cleaning is done.

Safety Reminders Before You Begin

Make sure the dishwasher is empty. Unplug it or turn off the circuit breaker if you plan to clean deep inside, especially around the filter or spray arms. Safety first—no one wants a surprise zap or splash of hot water.

Once you gather these simple tools, you’re ready to start learning how to clean Frigidaire dishwasher step by step—with real results.

Safety First: What to Do Before You Start Cleaning

Before you start cleaning, let’s check that everything is safe and set. When learning to clean your Frigidaire dishwasher, it’s essential to follow some safety tips. These tips help keep you and your appliance safe and prepare you for a thorough deep clean.

Unplug or Shut Off the Power

You won’t be using electricity for this job, so it’s best to disconnect the power source. If your dishwasher is hardwired, switch off the circuit breaker. If it has a visible plug, just unplug it from the outlet. This keeps you safe while reaching near the electrical components or spraying water around sensitive areas.

Turn Off the Water Supply (Optional but Smart)

In most cases, you won’t need to mess with the water line. However, if you’re going deep—such as checking hoses or removing parts near the base—it’s wise to shut off the water valve under your sink. It’s a small step that can prevent a big mess.

Wait Until It’s Completely Cool Inside

If your dishwasher just finished a cycle, give it some time. The inside can stay hot for up to 30 minutes. Cleaning a hot dishwasher isn’t just uncomfortable—it’s unsafe. Let it cool down before handling the filter, spray arms, or door seals.

Wear Gloves if You Have Sensitive Skin

Vinegar and baking soda are natural cleaners, but they can still dry out or irritate your skin if you scrub too vigorously. Wearing rubber gloves is a smart move, especially when cleaning tight corners with a brush.

Taking these few simple steps before you begin makes the entire process of cleaning a Frigidaire dishwasher smoother, safer, and much less stressful.

Step-by-Step Guide: How to Clean Frigidaire Dishwasher Thoroughly

Now that you’re prepped and ready, it’s time to get to work. Below is a complete, real-life breakdown of how to clean Frigidaire dishwasher inside and out. These steps are simple, doable, and effective—even if you’ve never cleaned a dishwasher before.

Step 1: Empty the Dishwasher and Remove the Racks

First, take everything out. Remove all the dishes, tools, and contents from both the top and bottom shelves. Most racks just pull out, but you can lift them gently if they are stuck. Don’t forget to take out the silverware basket as well. Put all your stuff in the sink to wash later.

Step 2: Clean the Filter (It’s Usually the Main Culprit)

Frigidaire dishwashers typically feature a twist-off filter located at the bottom of the unit. You’ll find it under the lower spray arm. Turn it counterclockwise to remove.

• Rinse it under warm water.
• Use an old toothbrush to scrub away grease, food particles, and mineral buildup.
• If it smells bad, soak it in a mixture of vinegar and warm water for 10–15 minutes.
• Rinse thoroughly and let it dry.

This step alone can make a big difference in performance and odor control.

Step 3: Scrub the Spray Arms

Your dishwasher’s spray arms are what shoot water to clean your dishes. If they’re clogged, your dishes won’t come out clean—no matter what detergent you use.

• Pull off the spray arms if they’re removable (most are).
• Use a toothpick, pin, or skewer to clear out any gunk in the small holes.
• Rinse them under hot water.
• Use a brush to scrub off greasy residue.
• Let them dry and reinstall when finished.

Step 4: Wipe the Door, Gasket, and Soap Dispenser

Open the door wide and use a damp cloth with vinegar or mild dish soap to clean the inner walls.

• Pay extra attention to the rubber gasket around the door—this is where mold loves to hide.
• Use a toothbrush to clean the folds and creases where grime tends to hide.
• Don’t forget the soap dispenser. Scrub it gently to remove buildup.

Step 5: Run a Vinegar Wash Cycle

Put a cup of white vinegar in a dishwasher-safe bowl or cup. Place it on the top rack. Do not add any detergent.

• Run the dishwasher on the hottest cycle.
• The vinegar will cut grease, dissolve mineral buildup, and kill odors.

This is one of the easiest and most effective ways to clean your machine thoroughly.

Step 6: Do a Baking Soda Boost

After the vinegar cycle, sprinkle 1 cup of baking soda across the bottom of the tub.

• Run a short hot water cycle.
• Baking soda scrubs and freshens, leaving your dishwasher smelling clean and fresh.

This two-step method is a game-changer.

Step 7: Clean and Reinstall the Racks and Utensil Holder

Now that everything else is clean, use a sponge to clean your racks and utensil tray.

• Scrub gently with warm, soapy water.
• Rinse and dry thoroughly.
• Slide everything back into place.

You’re done!

Taking the time to follow this process for cleaning a Frigidaire dishwasher not only improves its cleaning performance but also extends the life of your appliance, reduces unpleasant odors, and makes your kitchen feel fresher overall.

How Often Should You Clean Your Frigidaire Dishwasher?

Cleaning your dishwasher isn’t something you do just once a year—it’s something you should include in your regular cleaning schedule. After learning how to clean your Frigidaire dishwasher effectively, the next step is to determine how often you should clean it.

Quick Daily Habits Make a Big Difference

You don’t have to clean your dishwasher deep every day, but a few small actions go a long way:

• Always scrape food off dishes before loading.
• Wipe the door gasket once a week.
• Leave the door slightly ajar after each cycle to prevent mold growth.
• Check the bottom for food particles after heavy loads.

These habits help prevent buildup before it becomes a problem.

Do a Monthly Deep Clean for Best Results

A complete cleaning—like the step-by-step guide we just walked through—is best done once a month. This keeps filters clear, water flowing strong, and smells in check. If you live in an area with hard water or use your dishwasher every day, you may want to clean it every 2–3 weeks instead.

Don’t Forget Seasonal Maintenance

Every 3–4 months, go a little deeper:

• Check spray arms for hidden debris.
• Inspect hoses and seals for wear.
• Clean behind and under the appliance if possible.

Doing this ensures your dishwasher stays in top shape throughout the year.

By sticking to a simple cleaning routine and knowing how to clean Frigidaire dishwasher the right way, you can avoid repairs, keep your kitchen smelling fresh, and always have sparkling dishes—no extra rinse cycles needed.

Maintenance Tips to Keep Your Frigidaire Dishwasher Clean Longer

You don’t have to clean your dishwasher deep every week—especially if you follow a few smart habits in between. Once you’ve mastered how to clean a Frigidaire dishwasher the right way, these maintenance tips will help you extend the time between full scrubbing sessions without sacrificing performance.

Scrape, Don’t Rinse Dishes

Yes, it’s true—Frigidaire dishwashers are designed to handle some food residue. But too much can clog the filter and leave your dishes looking dingy. Just scrape large chunks off before loading. No need to pre-rinse; you’re just saving water and keeping your filter cleaner.

Keep the Filter in Check

You don’t have to clean the filter every time, but it’s a good idea to take a peek once a week. If you see gunk, give it a quick rinse. A clean filter equals better drainage and better cleaning performance.

Wipe the Door and Seal Weekly

Grab a damp cloth and wipe down the inside of the door, especially the rubber gasket. This is where moisture and food residue tend to hide. Cleaning it weekly helps prevent the development of mold and odors.

Use a Rinse Aid and the Right Detergent

Using a rinse aid, such as Finish or Jet-Dry, can help reduce hard water stains and improve drying efficiency. Also, ensure you’re using a high-quality detergent specifically designed for dishwashers—not dish soap. The right products matter.

Let It Breathe After Each Cycle

After the dishwasher finishes a cycle, open the door slightly and let it air out. This small habit helps prevent moisture buildup, which leads to mold and musty smells. It also helps your dishes dry faster.

Following these simple steps—along with knowing exactly how to clean Frigidaire dishwasher once a month—will keep your appliance smelling fresh, running smoothly, and cleaning like a pro for years to come.

Thoughtful Extras: Using Frigidaire ReadyClean™ and Other Cleaners

If you’ve followed all the DIY steps, you already know how to clean Frigidaire dishwasher using household staples like vinegar and baking soda. However, sometimes it’s worth using a specialty cleaner—especially if your dishwasher needs a thorough refresh or you want a quick, no-scrub option.

Why Use Frigidaire ReadyClean™?

Frigidaire’s line of cleaning products is made specifically for their appliances. Their ReadyClean™ Dishwasher Cleaner:

• Breaks down limescale, grease, and odor-causing residue
• Is safe for all Frigidaire models (and many others)
• Doesn’t require disassembly—just run it during a hot cycle
• Leaves a fresh scent without harsh chemicals

It’s an easy way to give your dishwasher a powerful deep clean without pulling out the toolbox or mixing ingredients.

When Should You Choose a Commercial Cleaner?

Even if you love natural methods, there are times when commercial products come in handy:

• You’re working with a lot of thick grease.  
• There are constant stains from hard water.  
• You’re looking for a quick and easy answer.  
• You’re getting ready for different seasons or preparing for visitors.

Commercial options—such as Finish®, Affresh®, or Cascade Dishwasher Cleaners—can give your dishwasher a professional-level clean in just one cycle.

Can You Combine Homemade and Store-Bought Methods?

Absolutely. Some homeowners like to alternate:

• One month: vinegar + baking soda
• Next month: Frigidaire ReadyClean™ packet
• Bonus tip: run a rinse cycle with lemon juice every few weeks to keep it smelling fresh

This balanced approach keeps buildup away and gives you the best of both worlds.

If you’re serious about maintaining a spotless appliance, knowing how to clean Frigidaire dishwasher includes being open to tools that make the process easier and more effective.

Troubleshooting Common Issues After Cleaning

So, you’ve cleaned your dishwasher very well, but it still doesn’t feel right. Don’t worry, even after you learn how to clean your Frigidaire dishwasher correctly, some common issues may still arise. Here’s how to fix them without needing to call a repair person right away.

There’s Still a Weird Smell

If the odor didn’t go away after cleaning:

• Double-check the filter—it may still have gunk trapped deep inside.
• Look inside the spray arms—clogged holes can trap food bits.
• Check the drain hose—it might have buildup or a kink.
• Try one more vinegar rinse cycle, followed by a baking soda rinse.
• Leave the door open overnight to allow the room to air out and remove moisture entirely.

Sometimes, smells linger if moisture stays trapped in the seals.

Water Is Pooling at the Bottom

Still seeing water at the base? This could mean:

• The filter or drain is still clogged—pull it out and recheck.
• The drain pump might be jammed (check your manual).
• A foreign object (like a glass shard or label) may be blocking the outlet.

Tip: Pour a small amount of vinegar and baking soda down the drain hole, let it sit for a few minutes, and then run a rinse cycle.

Spray Arms Aren’t Spinning

Your spray arms should rotate freely. If they’re not:

• They might be installed backward after cleaning.
• Try giving them a spin by hand—if they feel stiff, remove and recheck for debris.
• Ensure that nothing in the rack physically blocks them during cycles.

Even small pasta bits can become lodged inside the nozzles, which can affect the movement.

Dishes Still Look Dirty After Cleaning

You’ve done all the steps on how to clean Frigidaire dishwasher, but the dishes still aren’t spotless?

• Check that you’re loading dishes correctly—overloading blocks water flow.
• Ensure you’re using the correct detergent and a rinse aid.
• Run hot water in the sink before starting your dishwasher to preheat the water.
• Do a second cycle using Frigidaire ReadyClean™ for a deeper reset.

Conclusion

Knowing how to clean Frigidaire dishwasher properly ensures it runs efficiently, smells fresh, and lasts longer. By taking a few simple actions each month—like cleaning filters and spray arms, and using vinegar and baking soda—you can prevent expensive repairs and keep your dishes clean. Don’t wait for bad smells to start. Include taking care of the dishwasher in your cleaning habits.
