Maytag Dishwasher Filter Replacement Guide

Maytag dishwashers use a Dual Power Filtration system that combines two distinct filter components — a cylindrical upper filter and a flat lower mesh filter — working together with the stainless steel chopper blade. This three-stage system is unique among Whirlpool Corporation brands: while Whirlpool and KitchenAid use the same filter housing, Maytag adds an additional mesh stage between the upper filter and the drain pump, providing an extra layer of food particle capture before water recirculates to the spray arms.

Understanding the Dual Power Filtration System

The Maytag filter system has three components that work in sequence. The upper cylindrical filter catches large food particles — bones, seeds, label fragments — before they reach the spray arms. The lower flat filter (fine mesh) captures smaller particles that pass through the cylindrical filter. The stainless steel chopper blade (positioned below the filters) grinds any remaining solids before they reach the drain pump.

Cleaning is routine maintenance, not a repair. The cylindrical filter lifts out with a quarter-turn twist, and the flat filter lifts straight up underneath it. Maytag recommends monthly cleaning, but heavy-use households should clean weekly. Replacement is only needed when the mesh is physically torn, the filter frame is cracked, or buildup has calcified onto the mesh so thoroughly that soaking cannot restore flow.

Signs Your Filter Needs Cleaning or Replacement

• Gritty residue on glasses and flatware after washing — food particles are passing through a torn or clogged filter mesh and redepositing during the spray cycle
• Water pooling at the bottom of the tub after a cycle — a severely clogged filter restricts drainage flow, causing standing water
• Foul smell inside the dishwasher — trapped food particles decomposing in the filter mesh, especially common in households that run the dishwasher less than three times per week
• Extended cycle times — the turbidity sensor detects dirty recirculating water and adds rinse cycles, extending a Normal cycle from 90 minutes to two hours or more
• White calcium film on the filter mesh — hard water mineral deposits that resist normal cleaning and require vinegar soaking or filter replacement

Clean first, replace only if cleaning does not restore performance. Most filter problems are maintenance issues, not part failures.

Cost Breakdown

This is one of the simplest and cheapest dishwasher maintenance tasks. No tools are required for removal. The cost difference between cleaning and replacing is so small that most homeowners replace the filter assembly when cleaning no longer restores performance.

How to Clean the Maytag Dual Power Filter

1. Remove the lower dish rack to access the filter area on the tub floor
2. Twist the upper cylindrical filter counterclockwise approximately one-quarter turn and lift straight up
3. Lift the flat lower filter straight up from its seated position below where the cylindrical filter sat
4. Rinse both filters under warm running water — use a soft brush (old toothbrush) to remove food particles from the mesh
5. For calcium buildup, soak filters in white vinegar for 20–30 minutes, then scrub with a soft brush
6. Inspect both filters for tears, cracks, or holes in the mesh — any physical damage means replacement rather than cleaning
7. Reinstall the flat filter first (it sits in the lower recess), then insert the cylindrical filter and twist clockwise until it locks
8. Run a short rinse cycle to verify proper seating — water should not bypass the filters

When to Replace vs. When to Clean

Replace the filters when the mesh has physical tears or holes (even small ones allow food particles through), when the filter frame is cracked or warped (preventing proper seating in the housing), when calcium deposits have calcified so heavily that vinegar soaking cannot restore water flow, or when the filter mesh has yellowed and become brittle from age (typically after 5–7 years of use).

Clean the filters when food debris is the primary issue, when performance has gradually declined over weeks or months, or when you notice odor from the dishwasher interior. Monthly cleaning prevents most filter-related performance issues.

The Chopper Blade Connection

Maytag's stainless steel chopper blade sits below the filter assembly and grinds food waste before it reaches the drain pump. Unlike filter-only dishwashers, the chopper blade handles much of the debris processing. When the chopper blade dulls over time, it passes larger particles to the drain pump — but this does not affect filter cleaning frequency. The filters and chopper blade are independent maintenance items.

However, if you are replacing filters because of recurring drainage issues, inspect the chopper blade simultaneously. A dull chopper blade combined with new filters still produces drainage problems because the root cause is downstream of the filters.

Maytag Filter vs. Other Brands

Maytag's Dual Power Filtration adds an extra mesh stage compared to standard Whirlpool filters. The physical filter parts use the same housing dimensions as all Whirlpool Corporation dishwashers, but the additional mesh provides finer particle capture. When ordering, Maytag and Whirlpool cylindrical filters are interchangeable, but the lower mesh filter may differ — verify the part number matches your specific model.

Maytag Dishwasher Platform and Parts Cross-Reference

Maytag dishwashers are built on the Whirlpool Corporation platform, sharing approximately 80 percent parts compatibility with Whirlpool, KitchenAid, and Amana dishwashers. The same component listed under the Whirlpool brand name is manufactured in the same factory to the same specifications — often at a lower retail price. When ordering any replacement part, search both the Maytag model-specific part number and the Whirlpool Corporation cross-reference number (W10 or WP prefix) for the best price.

Maytag dishwashers include features not found on standard Whirlpool models: the PowerBlast cycle delivers intensified spray pressure for heavily soiled loads, the Dual Power Filtration system adds an extra mesh filtration stage, and the stainless steel chopper blade grinds food waste rather than filtering it. These features may put additional stress on specific components compared to standard Whirlpool operation.

Warranty Coverage — Check Before Ordering Parts

Maytag offers a 10-year limited parts warranty on select dishwasher components including the chopper blade, racks, and stainless steel tub — significantly longer than standard Whirlpool coverage. Before purchasing any replacement part, check your model's warranty documentation. Filing a warranty claim could save you the entire parts cost. Contact Maytag directly or visit their warranty lookup page with your model and serial number.

Diagnostic Mode Access

Enter the Whirlpool-platform diagnostic mode by pressing the button sequence documented on the tech sheet label inside the console panel (visible when you open the door and look at the top edge). Diagnostic mode displays stored fault codes and real-time sensor readings, allowing you to pinpoint failures before ordering parts. This diagnostic system is identical across all Whirlpool Corporation brands.

FAQ

How often should I clean my Maytag dishwasher filter?

Maytag recommends monthly cleaning. Households that run the dishwasher daily or wash heavily soiled cookware should clean weekly. Lift, rinse, brush, and reinstall — no tools required.

How much does a Maytag Dishwasher Filter cost?

A complete filter assembly (upper cylindrical plus lower flat mesh) costs $15–$40. Individual filter components cost $8–$25 each. This is one of the cheapest dishwasher parts available.

Can I run my Maytag dishwasher without the filter?

Technically yes, but food particles will recirculate through the spray arms and redeposit on dishes. Additionally, debris will reach the drain pump impeller without filtration, causing accelerated pump wear and potential pump failure.

Why does my Maytag dishwasher smell bad?

The most common cause is food particles trapped in the filter mesh. Remove both filters, clean them thoroughly with warm water and a soft brush, and run an empty cycle with a dishwasher cleaner or a cup of white vinegar placed on the top rack.
