How to Remove a Maytag Washing Machine Mold

Odor is more common in front-loaders because of their sealed door design, but top-loaders develop it too. Maytag counters it with the Fresh Hold option — 16 hours of fan tumbling to keep clothes fresh — but once odor has established, you have to actively remove it before any preventive feature can hold it back. This covers both Maytag MHW front-load and MVW top-load washers, leaning on the built-in Clean Washer cycle plus targeted manual treatment.

Tools, Supplies, and Safety First#

• 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, pull back the door gasket folds (front-load) to inspect for visible mold, check the dispenser drawer and its cavity, and shine a flashlight on the internal baffles. Mild means a musty smell only with no visible mold — 1-2 clean cycles will resolve it. Moderate means visible dark spots on the gasket or dispenser with persistent odor — the full protocol below. Severe means extensive black mold in the gasket folds with odor transferring to clothes — treatment plus possible seal replacement.

Step 2 — Run three consecutive Clean Washer cycles#

For moderate to severe cases, one cycle is not enough. Put an Affresh tablet in the drum, run the Clean Washer cycle, and the moment it finishes drop in another tablet and run it again, then a third time — each successive cycle attacks deeper layers of biofilm the previous one loosened but did not fully clear. On MHW front-loaders the cycle runs 60-75 minutes at maximum water temperature, and on MVW top-loaders the Power Agitator scrubs the tub walls with aggressive mechanical action during the clean.

Step 3 — Deep-clean the door boot seal (front-load MHW)#

After the clean cycles, pull back each fold of the rubber boot and spray it thoroughly with a 50/50 vinegar-water mix. On areas with visible black mold, apply hydrogen peroxide (3%) directly and let it sit 15 minutes — the bubbling means it is breaking down organic material. Scrub every gasket surface with a soft brush, including the easily-missed top folds, giving the water-pooling bottom the most attention, then wipe away all residue. Keep chlorine bleach off the gasket, since it degrades the rubber over time and cracks the seal; peroxide disinfects similarly without the damage.

Step 4 — Clean the dispenser system#

Remove the dispenser drawer (press the center release tab) and soak all its parts in a bowl of hot water with 1 tablespoon of dish soap for 30 minutes, scrubbing each compartment plus the softener siphon cap and bleach-compartment walls. Critically, also clean inside the dispenser cavity where the drawer slides — use a long brush or a cloth around a wooden spoon to reach the upper surfaces, because water jets spray upward there and mold grows on the cavity ceiling out of sight. On Optimal Dose bulk-tank models, drain and flush the whole reservoir and tubing by filling with warm water and running an empty cycle.

Step 5 — Clean the drum interior#

Even after three clean cycles, biofilm can cling to the drum baffles and tub perforations. Make a thick baking-soda-and-water paste, apply it to the baffles (the raised fins), the drum rim, and around the perforations, let it sit 30 minutes, wipe it away, and run a hot rinse cycle. On MVW top-loaders, work the paste into the agitator base and vanes where residue collects in the crevices of the dual-action Power Agitator.

Step 6 — Treat the drain-pump filter (front-load MHW)#

The drain-pump filter traps organic debris that decomposes and feeds odor. Open the filter access door, drain the residual water, remove the filter, and clean it thoroughly with hot soapy water and a brush, then wipe inside the housing with a vinegar-soaked cloth. This frequently-overlooked spot should be cleaned monthly going forward.

Step 7 — Address residual drum odor#

If odor persists after all that, biofilm has penetrated the outer tub surface you cannot reach from inside the drum. Run one additional cycle: pour 1 cup of chlorine bleach into the bleach dispenser and run a Normal cycle with hot water and no laundry, then follow immediately with a rinse cycle to flush all bleach residue. This treats the outer tub, hoses, and recirculation paths manual cleaning cannot reach. Do this only once, though — frequent bleach in the drum degrades the seals prematurely. If a single bleach cycle does not fully clear the smell, that is the signal the biofilm is deep in the sump hose or the outer tub rather than anywhere you can scrub, and repeating bleach cycles will punish the gasket long before it wins that fight — at that point the fix shifts from cleaning to a professional teardown of the tub-to-pump path.

Prevention Strategy (Post-Treatment)#

Once the odor is gone, keep it gone. Leave the door open between loads (the Fresh Hold fan assists air circulation; if you cannot leave it fully open, prop it ajar with a folded towel). Use the correct HE detergent amount, since excess detergent is the main fuel for mold. Run Clean Washer monthly, wipe the gasket after every front-load use (10 seconds with a dry cloth), and remove clothes promptly — the Overnight Wash & Dry feature on select MHW models fan-dries after washing so clothes do not sit in moisture. Run one hot cycle weekly even if you normally wash cold, clean the dispenser monthly, and go easy on Deep Fill for small top-load loads, since extra water plus too much detergent is the highest-risk combination for odor.

When Should You Call a Professional?#

EasyBear technicians serving Sacramento and the Bay Area carry Maytag-specific diagnostic tools and replacement parts on every service call. Call one if mold has penetrated behind the outer tub and produces odor from areas you cannot reach, if the boot seal shows structural damage (tears, permanent deformation, hardened sections) and needs replacing, if odor persists despite the full protocol (possibly sewer-gas backflow through an incorrectly installed drain hose), or if standing water remains in the drum after the cycle (a drain failure breeding bacteria).
