You've probably noticed that funky smell. Or maybe your glasses started coming out with that weird, gritty film that looks like sand but definitely isn't. It’s annoying. You bought a Maytag because they’re built like tanks, right? You expect them to just work. But even the toughest machine in your kitchen has a literal "stomach" that needs emptying. If you haven't looked at your Maytag dishwasher filter cleaning lately, you’re basically washing your plates in old lasagna water.
Most people assume the dishwasher just grinds everything up and sends it down the drain. While some older Maytag models have a hard food disposer (the ones that sound like a jet engine taking off), the newer, quieter models rely on a filtration system. It’s a trade-off. You get a quiet kitchen, but you get the manual labor of cleaning out a plastic mesh cylinder every few weeks. Honestly, it's a bit gross, but it's the difference between sparkling silverware and stuff you're embarrassed to give to a guest.
How to Handle Maytag Dishwasher Filter Cleaning Without Breaking Anything
First off, stop overthinking it. You don't need a toolbox. You don't even need a degree in engineering. Most modern Maytag units (think the MDB series) use a two-part filter system. There's a circular assembly sitting right at the bottom under the lower spray arm. You just grab that top dial, give it a quarter-turn counterclockwise, and lift.
It should pop right out. If it feels stuck, don't yank it. Sometimes a bit of calcium buildup or a stray toothpick can wedge it in there. Just wiggle it gently. Once that's out, you'll see the lower filter—a flat, mesh screen. Lift that out too. If you’ve never done this, prepare yourself. It’s going to be slimy. There might be a greyish sludge, which is basically a cocktail of fats, proteins, and undissolved detergent.
Why the Mesh Matters
The mesh on these filters is incredibly fine. We're talking microns. Its job is to keep tiny particles from recirculating and sandblasting your dishes. When those holes get plugged with grease, the pump has to work harder. It’s like trying to run a marathon while breathing through a cocktail straw. Eventually, the motor gets stressed. That's how you end up with a $400 repair bill for a part that could have been saved by five minutes at the kitchen sink.
Take the assembly to the sink. Use warm water. Avoid using a wire brush or anything abrasive because you'll tear the mesh, and once there's a hole, the filter is useless. A soft toothbrush is your best friend here. A little bit of Dawn dish soap goes a long way in breaking down that stubborn grease. If you see white crusty stuff, that’s hard water scale. A quick soak in a bowl of white vinegar will dissolve those minerals faster than you can find a YouTube tutorial on it.

The "Auto-Clean" Myth and Why Manual Intervention Wins
Maytag markets some of these machines with "Dual Power Filtration." It sounds fancy. It sounds like it should be invincible. But even the best engineering can't handle a family that doesn't scrape their plates. If you're tossing plates with chunks of brie or dried oatmeal directly into the rack, you're asking for trouble.
The "Dual Power" system actually uses a micro-filter and a small chopper blade. It's better than most, sure. But it’s not a woodchipper. Tiny seeds from raspberries or tomatoes are the ultimate enemy of the Maytag dishwasher filter cleaning routine. They are just the right size to get stuck in the mesh. They don't break down. They just sit there, vibrating, until they've collected enough gunk to create a waterproof seal over your filter.
Signs You've Waited Too Long
- The water isn't draining completely.
- There's a literal "ring" of sludge at the bottom of the tub.
- Your "Clean" light is blinking in a weird pattern.
- The dishes feel "sandy" to the touch.
If you see these, you’re already behind the curve. According to most appliance repair experts, like the folks over at Appliance Repair Forum or the veterans at RepairClinic, the number one cause of "poor wash performance" calls is simply a dirty filter. It's rarely a mechanical failure. It's just maintenance neglect.
Beyond the Filter: The Stuff Nobody Checks
While you've got the filter out, look down into the sump. That’s the hole where the water goes. You might see a bit of standing water; that’s normal and keeps the seals from drying out. But check for foreign objects. I’ve found glass shards, plastic bread ties, and even a stray dime in there. These things won't get caught by the filter because they fall in while the filter is being moved or they manage to sneak past the edges.
Check the spray arms too. If your filter was clogged, some of that debris probably made its way into the tiny holes of the spray arms. Use a toothpick to poke out any gunk. If the water can't spray out, it doesn't matter how clean your filter is; your dishes are just getting a lukewarm steam bath instead of a scrub.

Hard Water Is the Secret Boss
If you live in a place like Phoenix or Indianapolis, your water is probably "harder" than a diamond. Calcium and magnesium are the silent killers of dishwashers. They create a "scale" that looks like white chalk. This scale loves to grow on the filter mesh. Once it starts, it provides a textured surface for grease to grab onto.
You should be using a dishwasher cleaner—something like Affresh—once a month. Just toss it in and run a heavy cycle. It's formulated to chemically break down those minerals. Think of it as a detox for your machine. It keeps the internal sensors clean too. Maytag actually recommends this in their manuals, though most of us throw those in a junk drawer and never look at them again.
Detergent Matters More Than You Think
Stop using too much soap. Seriously. Most people fill that little cup to the brim. Modern concentrated pods or gels are powerful. If you use too much, it doesn't all rinse away. It creates a "suds lock" and leaves a film on the filter. If you see a lot of white cloudy residue on your filter after a wash, try cutting back on the detergent or switching to a high-quality tablet like Cascade Platinum or Finish Quantum. These contain enzymes that actually "eat" the food particles, making the Maytag dishwasher filter cleaning process a lot less disgusting when you finally get around to it.
Real World Maintenance Schedule
Forget what the marketing says about "maintenance-free." If you use your dishwasher daily, you need a realistic plan.
- Once a week: Do a quick visual check. If you see a stray pea or a bit of paper label at the bottom, grab it.
- Once a month: Pull the filter. Give it a rinse under the tap. It should take two minutes.
- Every three months: Deep clean the filter with a toothbrush and soak it in vinegar if you see scale. Run a cleaning cycle with a dedicated tablet.
- Once a year: Check the drain hose for kinks or clogs. This is where the "hidden" smells often live.
It's about being proactive. You spent good money on a Maytag. Taking care of the filter is how you make sure that machine lasts fifteen years instead of five.

Actionable Steps for a Cleaner Machine
Start by clearing the bottom rack entirely. Reach in and twist the filter out—it’s a simple "lefty-loosey" motion. Rinse it under the hottest water your tap can provide. If the mesh looks cloudy, soak it in a 50/50 mix of white vinegar and water for thirty minutes. While it's soaking, take a damp cloth and wipe the rubber seal around the door. This "gasket" is a magnet for mold and old soap.
Reassemble the filter by lining up the arrows. You’ll usually see two arrows on the plastic housing that need to point at each other. Lock it in place. If it's loose, it will float during the cycle, and then all that debris will go straight into your pump, which is a recipe for disaster.
Check the "Sani-Rinse" or "Hi-Temp Wash" options on your control panel for your next load. These settings get the water hot enough to actually melt the animal fats that clog filters. If you always run "Normal" or "Eco" cycles, the water might not be getting hot enough to keep the internal plumbing clear. Occasionally running a scorching hot cycle is like a "power wash" for the insides of the pipes.
Finally, check your water heater. If the water coming out of your kitchen sink isn't at least 120 degrees Fahrenheit, your dishwasher is fighting a losing battle. Turn the tap on until it's hot before you hit "Start" on the dishwasher. This ensures the machine starts with hot water rather than wasting the first ten minutes of the cycle trying to heat up cold water from the pipes. These small habits, combined with regular filter maintenance, are what keep a Maytag running like the industrial beast it was meant to be.
