Is your dishwasher leaving behind gunky plates or musty smells? You might be overlooking one small part that plays a considerable role—your filter. If you’ve been wondering how to clean Amana dishwasher filter, you’re not alone. Most homeowners don’t even know it’s there—until it’s clogged and ruining every wash cycle. Don’t worry—you don’t need a technician or special tools. We are here to help you. This guide will show you how to clean your filter easily and efficiently, just like a pro. Get ready for clean dishes that smell good and a dishwasher that works great by following a simple 10-minute routine.

Why Cleaning Your Amana Dishwasher Filter Matters

Have you ever opened your dishwasher after it’s done and seen bits of food on your “clean” plates? Or have you noticed a foul smell when you open the door? These aren’t just accidents; they mean that your Amana dishwasher filter needs to be cleaned.

1. It Keeps Your Dishes Truly Clean

A dirty filter means dirty water. As the dishwasher cycles, food debris and grime trapped in the filter get pushed back onto your plates and glasses. Regular filter cleaning ensures every cycle uses fresh water, so your dishes come out clean, not gritty.

2. It Prevents Nasty Smells

Food particles stuck in a warm, damp space? That’s a breeding ground for bacteria and mould. The result? A dishwasher that smells worse than your garbage can. Cleaning the filter removes decaying bits that cause those awful kitchen odours.

3. It Protects the Pump and Motor

When your filter becomes blocked, it requires the motor and pump to work harder to move water through the system. Over time, this can cause machines to malfunction or break down. Cleaning the filter is like changing your car’s oil. It’s an easy and inexpensive way to avoid costly repairs later.

4. It Avoids Costly Repairs

Amana dishwashers are reliable, but no machine is perfect. A blocked filter can cause issues with draining, water collecting in the tub, or showing error messages. Cleaning your machine regularly helps it work more efficiently and last longer.

5. It Takes Less Than 10 Minutes

This isn’t a complex repair job. You don’t need a technician. Just 10 minutes, some warm water, and a soft brush—and you’re set. You’ll be shocked at the difference it makes.

If you’re not already cleaning your Amana dishwasher filter every 3–4 weeks, now’s the time to start. Don’t worry—I’ll walk you through it step-by-step in the next section. Whether you have an old Amana model or a new stainless steel one, this guide will help you.

Where Is the Filter on an Amana Dishwasher?

Before you start cleaning, you need to know where the filter is located and how to remove it safely. Luckily, Amana has kept it simple, but each model may have slight variations. So let’s walk through the universal process in the most human-friendly way possible.

Where Is the Filter in an Amana Dishwasher?

The filter is typically found at the bottom centre of the tub, beneath the lower spray arm. It’s part of the dishwasher’s internal drainage system and usually consists of:

• A fine mesh cylindrical filter (often with a twist-lock)
• A flat coarse filter screen underneath
• A sump area, where food and water collect before draining

Tip: If you’re unsure where it is, check your user manual or look for a circular handle located under the spray arm.

How to Identify Your Amana Filter Type

Before cleaning your Amana dishwasher filter correctly, you need to determine the type of filter you have. Not all Amana dishwashers are built the same—some have removable mesh filters, while others (especially older models) rely on self-cleaning systems. If you’ve ever stood there wondering, “Why can’t I twist this thing off?”—you’re not alone.

1) Removable Mesh Filters (Modern Amana Models)

If you own a newer Amana dishwasher (most models built after 2010), it likely has a removable filter system.

Here’s how to tell:

• Located under the lower spray arm
• It typically features a round mesh filter and a flat, rough screen.
• Has a twist-to-lock mechanism—you can rotate it counterclockwise to remove it
• Designed for monthly manual cleaning

Why this matters: These filters are user-maintainable, which means you can clean them regularly to avoid performance issues, odours, and clogs.

Pro tip: If you notice a plastic circular handle at the base of your tub, congrats! You have a removable mesh filter.

2) Self-Cleaning Filters (Older Amana Models)

Older Amana dishwashers (especially models from the early 2000s and before) usually have a self-cleaning filter system, also known as a grind-based filter.

Here’s how to recognise it:

• You won’t see a removable filter
• There’s no twistable part under the lower spray arm
• May include a grinder or chopper blade system that pulverises food debris
• Typically noisier than modern models due to the grinding action

Important note: These filters typically do not require manual cleaning, but food and grease can still accumulate around the sump, especially when running shorter cycles or using low-quality detergent.

If you don’t see any filters at the bottom, the machine is probably self-cleaning.

How to Find Your Amana Dishwasher Model Number

Your model number will allow you to recognise your filter type and find detailed cleaning instructions.

Where to look:

• Firstly, open the dishwasher door
• And then, look along the door edge, top of the door frame, or side wall of the tub
• The model number usually starts with ADB, W, or another 3-4 letter prefix

Once you find the model number, you can:

• Look it up on Amana’s official support site
• Download your user manual
• Watch YouTube filter guides by entering your model + “filter cleaning”

Example: “Amana ADB1400AGW filter cleaning”

Tools Needed to Clean Amana Dishwasher Filter

You don’t need special tools to clean your Amana dishwasher filter, but using the right supplies can make it easier and quicker. If you have a greasy mess, stuck-on food, or need to clean every month, the checklist below will help you.

Essential Tools You’ll Need

Rubber gloves

To keep your hands safe from hot water, grime, and sharp debris.

Soft-bristle toothbrush or old dish brush

Ideal for scrubbing mesh filters without damaging the delicate screen.

Dish soap (mild)

Perfect for breaking down grease without harming plastic components.

White vinegar

A natural disinfectant and degreaser that’s safe for dishwasher use.

Warm water

Required for rinsing and soaking filters.

Microfiber cloth or paper towels

For drying parts before reinstalling.

Toothpick or plastic pick

Supports unclogging tiny holes in your mesh filter or spray arms.

Optional (But Recommended) Supplies

Baking soda

Excellent for neutralising odours and removing stubborn grime.

Dishwasher cleaner tablets 

(like Affresh or Finish)Helps maintain the machine and keep the inside fresh between filter cleanings.

Small bowl or basin

Makes soaking your filter parts easier and less messy.

Tweezers or zip ties

Helpful in pulling out debris stuck in the sump or corners.

Prep Tips Before You Start

• Bypass harsh chemicals, such as bleach, as they can damage seals and gaskets.
• Do not utilise wire brushes or steel wool on filters, as they can scratch the mesh.
• For mineral buildup, soak parts in a vinegar-baking soda mix for 15–30 minutes.
• If you notice a strong smell even after cleaning, also check the spray arms and rubber door seals.

How to Clean Amana Dishwasher Filter Step-by-Step

If your Amana dishwasher isn’t cleaning well or smells off, it’s probably time to give your filter system a deep clean. Many people forget the filter even exists—until things go wrong. But don’t worry. In just 15 minutes, you can get your filter spotless again.

Use this easy and friendly guide to keep things calm and straightforward.

Step 1: Power Down Safely

Before you begin:

• Please switch off the dishwasher. Disconnect it or turn off the power at the circuit breaker.  
• Make sure it’s cool. Wait for at least 30 minutes after the washing cycle is done.  
• Turn off the water (it’s not necessary, but it helps if you’re near the sump).

Lay a towel under the door to catch drips or grime.

Step 2: Remove the Bottom Dish Rack

Please remove the bottom rack and set it aside. This allows you to easily access the bottom tub, where the filter is located.

Step 3: Locate the Filter Assembly

In most Amana models, the filter is located under the bottom spray arm, typically centred at the base of the dishwasher tub.

It usually has:

• A cylindrical mesh filter (fine filter)
• A flat mesh or plastic plate around it (coarse filter)
• The drain sump underneath

If you don’t immediately see a twist-lock handle, refer to your user manual (or check our tips in Section 3).

Step 4: Remove the Filter

Most modern Amana filters twist out easily.

• Grip the circular handle and twist counterclockwise (about 1/4 turn).
• Lift gently to remove the cylindrical filter.
• Remove the flat mesh filter underneath.

If stuck: Don’t force it! Pour warm vinegar over the filter area and wait 10–15 minutes. Try twisting again with a rubber glove or jar opener.

Step 5: Rinse and Scrub the Filters

Take both filters to the sink.

• Rinse under warm water.
• Use a soft brush (or an old toothbrush) with mild dish soap.
• Gently scrub both sides of the mesh and plastic casing.

For tough gunk:

• Combine 1 cup of warm water, 1 cup of white vinegar, and one teaspoon of baking soda.  
• Soak the filters in a bowl or container for 15-30 minutes.  
• Wash again and rinse well.

Step 6: Check and Clean the Filter Area

Back in the dishwasher:

• Use a cloth or sponge to clean the inside of the filter holder.  
• Check the drain sump and use tweezers or a plastic zip tie to take out any food or glass pieces.  
• Turn the spray arm and check it for blockages. If you find any, use a pin to clean out the holes.

Step 7: Dry and Reassemble

Utilise a clean microfiber cloth to dry the filters.

Then:

• Put the flat coarse filter back in first.  
• Next, insert the round filter and turn it to the right until you hear a click or it feels snug.  
• Ensure the filter is securely in place—if it’s loose, it won’t protect the pump.

Step 8: Run a Short Test Cycle

With the filter reinstalled:

• Return the lower rack to its place.
• Turn power and water back on.
• Run a hot water rinse cycle without any clothes to ensure everything is working correctly.

That’s it—you’ve now successfully cleaned your Amana dishwasher filter like a pro.

Troubleshooting Amana Filter-Related Issues

You cleaned your Amana dishwasher filter, hoping for clean dishes and no strange smells. But if your dishwasher is still not working, you’re not the only one. Even after a thorough cleaning, many dishwasher owners remain confused. “Why are my dishes not clean. “Why does it smell like something died in there?” or worse — “Why is there water pooling at the bottom!?”

Let’s walk through the most common Amana filter-related problems and learn how to solve them quickly without needing a technician.

1. The Filter Is Stuck and Won’t Budge

You’re trying to turn it, using all your strength, but it’s not working. If your filter seems stuck, don’t worry. This often occurs, especially if the area hasn’t been cleaned for some time.

Why does it happen?

• Built-up food particles or grease have locked it in place
• Hard water deposits formed around the base
• You’re turning it the wrong way (it happens to the best of us)

What to do:

• Pour warm white vinegar around the base of the filter. Let it soak for 10–15 minutes.
• Try again with rubber gloves for extra grip, turning counterclockwise.
• Still won’t move? Tap gently with a wooden spoon handle to loosen any stubborn gunk.

Avoid using pliers or metal tools — they may crack your filter before resolving the issue.

2. I Cleaned the Filter… But My Dishwasher Still Smells

This one’s frustrating. You did everything right — cleaned the filter, ran a rinse — but your dishwasher still smells like last week’s dinner.

Why does it happen?

• Bits of food are hiding in the spray arms or sump
• The door gasket might have mould or mildew
• Your dishwasher might need a deeper clean beyond just the filter

Quick fix:

• Wipe down the rubber door seal with vinegar and a soft cloth
• Remove and clean the spray arms (poke out holes with a toothpick)
• Put a small amount of baking soda on the bottom of the tub.
• Then run an empty hot process with a cup of white vinegar on the top rack.

Boom. Smells gone.

3. My Dishes Still Come Out Dirty

This might be the #1 complaint after filter cleaning. If your dishes still have spots, food bits, or a greasy film, the filter isn’t the only thing to check.

Possible culprits:

• Spray arms are clogged or not spinning properly
• You’re overloading the racks, blocking water flow
• Hard water or poor-quality detergent

What to do:

• Clean out spray arms
• Make sure dishes aren’t crammed together — leave space
• Use a better detergent (Cascade Platinum and Finish Quantum are solid choices)
• Add a rinse aid if you have hard water

If you’re doing all this and things are still dirty, it’s time to clean the whole machine deep.

4. Standing Water at the Bottom of the Dishwasher

This one causes panic fast. You open your dishwasher and find water just sitting there. But don’t freak out — it doesn’t always mean your machine is broken.

Why it’s happening:

• The filter is still clogged or wasn’t reinstalled correctly
• Food particles are blocking the drain area or sump
• The drain hose is kinked or clogged

What to do:

• Re-clean the filter AND the sump (check for seeds, rice, glass bits)
• Run a short rinse cycle — does the water drain now?
• Check under the sink — is the drain hose bent or blocked?

Pro tip

If your dishwasher still doesn’t drain after a rinse cycle, try this simple hack:

Disconnect the drain hose (with a towel underneath), then flush it with hot water or gently blow through it to check for blockages. You’d be surprised how often a popcorn kernel or broken glass gets lodged inside.

5. Filter Keeps Getting Dirty Too Fast

Ever feel like you just cleaned the filter last week… and now it’s grimy again?

Why does it happen?

• You’re loading super greasy pans without pre-scraping
• Your detergent isn’t breaking down fats properly
• Too many starchy or sticky foods (like pasta or rice) are going in un-rinsed

Fix it:

• Pre-scrape (not pre-wash) your dishes — scrape chunks into the trash
• Upgrade to a high-efficiency detergent
• Add white vinegar once a week to your cycle (it helps dissolve grease)
• Use a dishwasher cleaner tablet every 3–4 weeks — it targets the filter and sump zone

This simple habit keeps your Amana dishwasher filter cleaner for longer and extends its lifespan.

6. Dishwasher Is Suddenly Loud or Buzzing

Is your once-quiet Amana now buzzing, rattling, or gurgling mid-cycle? That’s usually not normal, and it’s often connected to the filter.

What could be wrong:

• Bits of bone, glass, or food debris got past the filter
• Spray arms or the circulation pump are struggling
• The filter wasn’t appropriately reinstalled and is vibrating

What to do:

• Power off your machine and pull the filter back out
• Check the impeller area (where the water drains) for stuck debris
• Remove the spray arms and rinse them
• Run a test rinse with the filter securely locked in place

Still noisy? You may want to call a tech, but at least you’ve ruled out filter-related causes.

Long‑Term Maintenance Tips

• Inspect the filter every 2 weeks if you run daily loads.
• Run a vinegar + baking soda clean-out monthly.
• Never use harsh cleaners like bleach.
• Stick to high-efficiency detergents.
• Watch for early signs, such as cloudy water, unusual odours, and sediment at the bottom of the tank.
