How to Remove Mold and Odors from a Maytag Washing Machine

Persistent musty odors and visible mold in washing machines are caused by moisture and detergent residue creating a breeding environment for bacteria and mildew. This is more common in front-load washers due to their sealed door design, but top-load models can develop odors too. Maytag addresses this with the Fresh Hold option (16 hours of fan tumbling to keep clothes fresh), but when odor has already established, active removal is needed before preventive features can keep it at bay.

This guide covers both Maytag MHW front-load and MVW top-load washers. The cleaning approach leverages Maytag's built-in Clean Washer cycle combined with targeted manual treatment of affected areas.

Before You Start

• Tools needed: Spray bottle, soft-bristle brush (old toothbrush), microfiber cloths, flashlight
• Supplies needed: Affresh washer cleaner tablets (3-4), white vinegar, baking soda, hydrogen peroxide (3%), mild dish soap
• Time required: 60-90 minutes active work plus 2-3 full wash cycles
• Difficulty: Beginner
• Safety warning: Never mix bleach with vinegar — this creates toxic chlorine gas. Use them in separate cycles with a rinse between.

Step-by-Step Instructions

Step 1: Assess the Severity

Open the door and smell the drum interior. Pull back the door gasket folds (front-load) and inspect for visible mold. Check the dispenser drawer and its cavity. Shine a flashlight into the drum and look at the internal baffles.

Severity levels:

• Mild: Musty smell only, no visible mold — 1-2 clean cycles will resolve
• Moderate: Visible dark spots on gasket or dispenser, persistent odor — full treatment protocol
• Severe: Extensive black mold in gasket folds, odor transfers to clothes — treatment plus possible seal replacement

Step 2: Run Three Consecutive Clean Washer Cycles

For moderate to severe cases, a single clean cycle is insufficient. Place an Affresh tablet in the drum and run the Clean Washer cycle. When complete, immediately place another tablet and run again. Repeat a third time. Each successive cycle attacks deeper layers of biofilm that the previous cycle loosened but did not fully remove.

On MHW front-load models, the Clean Washer cycle runs 60-75 minutes at maximum water temperature. On MVW top-load models, the Power Agitator provides aggressive mechanical action that scrubs the tub walls during the clean cycle.

Step 3: Deep Clean the Door Boot Seal (Front-Load MHW)

After the clean cycles, pull back each fold of the rubber door gasket and spray thoroughly with a 50/50 vinegar-water solution. For areas with visible black mold, apply hydrogen peroxide (3%) directly and let it sit for 15 minutes. The peroxide bubbling indicates it is actively breaking down organic material.

Use a soft-bristle brush to scrub all gasket surfaces, including the top folds that are easy to miss. The bottom of the gasket where water pools requires the most attention. Wipe away all residue with a microfiber cloth.

Do not use chlorine bleach on the gasket — it degrades the rubber compound over time, causing cracking and eventual seal failure. Hydrogen peroxide achieves similar disinfection without rubber damage.

Step 4: Clean the Dispenser System

Remove the dispenser drawer (press the center release tab). Soak all drawer components in a bowl of hot water with 1 tablespoon of dish soap for 30 minutes. Scrub each compartment including the fabric softener siphon cap and the bleach compartment walls.

Critically — also clean inside the dispenser cavity (the housing where the drawer slides). Use a long brush or cloth wrapped around a wooden spoon to reach the upper surfaces. Water jets spray upward to flush detergent from the drawer, and mold grows on the ceiling of this cavity where users cannot easily see it.

For Optimal Dose (bulk detergent tank) models, drain and flush the entire reservoir and tubing by filling with warm water and running an empty cycle.

Step 5: Clean the Drum Interior

Even after three Clean Washer cycles, biofilm can persist on drum baffles and the tub perforations. Make a paste of baking soda and water (thick enough to cling). Apply it to the drum baffles (the raised fins), the drum rim, and around the tub perforations. Let it sit for 30 minutes, then wipe away and run a hot rinse cycle.

On MVW top-load models, apply the paste to the agitator base and vanes where residue accumulates in the crevices of the dual-action Power Agitator design.

Step 6: Treat the Drain Pump Filter (Front-Load MHW)

The drain pump filter traps organic debris that decomposes and contributes to odor. Open the filter access door, drain the residual water, and remove the filter. Clean it thoroughly with hot soapy water and a brush. Also wipe inside the filter housing with a vinegar-soaked cloth. A frequently overlooked source of odor, this area should be cleaned monthly going forward.

Step 7: Address Residual Drum Odor

If odor persists after the above steps, the biofilm has penetrated the outer tub surface (the part you cannot directly access from inside the drum). Run one additional cycle: pour 1 cup of chlorine bleach into the bleach dispenser compartment and run a Normal cycle with hot water and no laundry. Follow with an immediate rinse cycle to flush all bleach residue. This treats the outer tub, hoses, and recirculation pathways that manual cleaning cannot reach.

Note: Do this only once. Regular bleach use in the drum can cause premature seal degradation if used frequently.

Prevention Strategy (Post-Treatment)

Once odor is eliminated, prevent recurrence:

1. Leave the door open between loads — on MHW models, the Fresh Hold fan system assists air circulation. If you cannot leave the door fully open, at minimum prop it ajar with a folded towel
2. Use correct HE detergent amount — excess detergent is the primary fuel for mold growth. Less is more in HE machines
3. Run Clean Washer monthly — set a phone reminder, or follow the machine's built-in reminder
4. Wipe the gasket after every use (front-load) — takes 10 seconds with a dry cloth
5. Remove clothes promptly — the Overnight Wash & Dry feature on select MHW models runs a fan-dry cycle after washing so clothes do not sit in moisture if you forget
6. Run a hot cycle weekly — even if your normal laundry is cold wash, one hot cycle per week prevents biofilm establishment
7. Clean the dispenser monthly — remove, rinse, dry thoroughly
8. Deep Fill caution (top-load) — do not routinely use Deep Fill with extra water for small loads. Excess water combined with too much detergent creates the highest-risk conditions for odor development

When to Call a Professional

• Mold has penetrated behind the outer tub, producing odor from areas you cannot access or treat
• The door boot seal shows structural damage (tears, permanent deformation, hardened sections) and needs replacement
• Odor persists despite complete treatment protocol — may indicate a plumbing issue (sewer gas backflow through incorrectly installed drain hose)
• You observe standing water in the drum after the cycle completes — indicates a drain system failure allowing stagnant water to breed bacteria

FAQ

Q: Why does my Maytag front-load washer smell like mold? A: The sealed door design of front-load washers traps moisture in the door boot gasket folds after each cycle. Combined with detergent residue (especially from using too much or non-HE detergent), this creates ideal conditions for mold and mildew growth. Regular gasket wiping and monthly Clean Washer cycles prevent this entirely.

Q: Does the Fresh Hold feature prevent odor? A: Fresh Hold helps prevent clothes from developing odor by running a fan that tumbles them for up to 16 hours after the cycle. However, it does not prevent machine odor from gasket mold or tub biofilm. You still need regular cleaning and the door-open practice between loads.

Q: Should I replace the door gasket if mold keeps coming back? A: If mold recurs within 2-3 weeks despite thorough cleaning and proper prevention practices, the seal may have permanent subsurface contamination. Replacement costs $80-$150 for the part. However, first verify that you are following all prevention steps — most recurrence is caused by continued excess detergent use or leaving the door closed between loads.

Q: Can mold from my washer make my family sick? A: Mold in washing machines can transfer to clothes and trigger allergic reactions (sneezing, skin irritation, respiratory symptoms) in sensitive individuals. Black mold (Stachybotrys) is rare in washers — most washer mold is Cladosporium or Aspergillus, which are less dangerous but still irritating. Prompt treatment is recommended.
