How to Deep-Clean a Whirlpool Washing Machine

Your Whirlpool washing machine is designed with self-cleaning features, but regular manual cleaning prevents mold growth in the door bellow, mineral deposits on the steam nozzle, and residue buildup inside the Load & Go dispenser. This guide covers both front-load WFW series and top-load WTW series machines with brand-specific procedures that go beyond generic advice.

Whirlpool recommends running the Clean Washer cycle monthly, but many owners neglect the manual wipe-down steps that actually prevent the musty smell problem. The FreshHold feature (which tumbles and fans clothes after a cycle ends) can mask early mold growth by keeping clothes fresh even when the tub is contaminated.

Before You Start

• Tools needed: Microfiber cloths, old toothbrush, Affresh washing machine cleaner tablets (W10501250), white vinegar, spray bottle, flashlight
• Parts needed: None (cleaning procedure)
• Time required: 45 minutes active, plus one clean cycle (about 1 hour)
• Difficulty: Beginner
• Safety warning: Disconnect power before manually cleaning interior components. Leave the door open afterward to allow complete drying.

Step-by-Step Instructions

Step 1: Run the Clean Washer Cycle with Affresh

Drop one Affresh tablet (Whirlpool part W10501250) directly into the empty drum. Do not place it in the detergent dispenser. Select the Clean Washer cycle on the control panel. On WFW models, this is a dedicated button. On WTW models, it may be a cycle option under the Heavy Duty setting. The cycle runs extra-hot water and extended agitation to dissolve buildup from the inner tub walls and drain system.

If you do not have Affresh tablets, use 2 cups of white vinegar poured directly into the drum. Do not substitute bleach and vinegar together as they create toxic chlorine gas. Use one or the other per cycle.

Step 2: Clean the Door Bellow (Front-Load WFW Only)

The rubber door bellow (gasket) on WFW front-load models is the most common source of mold odor. After the clean cycle finishes, pull back the folds of the bellow and inspect for black mold spots, trapped coins, hairpins, or lint. Use a 50/50 vinegar-water spray and a microfiber cloth to wipe all surfaces inside the folds. For stubborn mold, apply a paste of baking soda and water, let it sit 15 minutes, then scrub with an old toothbrush.

Check the drain holes at the bottom of the bellow where water collects. These small ports can clog with lint, creating a perfect mold incubation zone. Clear them with a pipe cleaner or thin brush.

Step 3: Clean the Load & Go Dispenser (If Equipped)

The Load & Go bulk detergent system holds approximately 40 loads of detergent in an internal tank. Over time, the dispensing valve and internal channels develop a sticky residue that can restrict flow and cause under-dosing. Remove the detergent tray by pulling it out fully and pressing the release tab. Wash all removable parts under hot running water. Use a small bottle brush to clean inside the dispensing slot.

For top-load models without Load & Go, simply remove the fabric softener and bleach dispensers (they usually lift out) and soak in hot soapy water for 15 minutes.

Step 4: Clean the Drain Pump Filter (Front-Load)

On WFW front-load machines, locate the small access door at the lower-left front panel. Place a shallow pan or towels beneath it. Turn the drain pump filter cap counterclockwise slowly, allowing residual water to drain. Remove the filter completely and rinse it under running water. Remove any trapped items: coins, hair ties, small clothing articles. These items can damage the drain pump (WPW10730972) if left to accumulate.

Step 5: Wipe Down the Drum and Detergent Residue

With a flashlight, inspect the stainless steel drum interior for white mineral deposits, especially around the steam nozzle inlet holes on steam-equipped WFW models. Hard water causes mineral scale that can leave white marks on dark clothing. Wipe the entire drum surface with a vinegar-dampened cloth. Pay extra attention to the top edge of the drum opening where soap residue accumulates out of sight.

Step 6: Clean the Steam Nozzle (Steam-Equipped Models)

If your Whirlpool WFW has a steam function, locate the small nozzle inside the door area at the top. Mineral buildup from hard water can block this nozzle over time, reducing steam performance. Dip a cloth in vinegar and wrap it around the nozzle for 10 minutes to dissolve scale. Then use a wooden toothpick to clear any remaining deposits from the nozzle opening. Never use metal tools on the nozzle as it can damage the brass fitting.

Step 7: Run a Final Rinse Cycle

Run a Quick Rinse cycle with no detergent and no clothes to flush all loosened residue from the system. This clears vinegar and dissolved deposits from the drain pump, hoses, and internal passages.

Step 8: Leave the Door Ajar

After cleaning, leave the door open at least 4 inches for air circulation. The FreshHold fan system helps, but cannot fully replace open-air drying of the drum and bellow surfaces. On top-load WTW models, leave the lid open until the drum is completely dry to the touch.

Preventing Future Buildup

The most common cause of washing machine odor is using too much detergent. With Whirlpool's Adaptive Wash sensors, the machine adjusts water levels precisely. Excess detergent does not rinse away completely and creates a biofilm inside the outer tub that you cannot see. Follow Whirlpool's recommendation of 2 tablespoons of HE detergent for a normal load. The Load & Go system auto-doses correctly only if you calibrate it with your specific detergent brand.

Always remove wet laundry promptly. The FreshHold option gives you up to 12 hours of periodic tumbling and fan circulation, but it is not a substitute for removing clothes same-day. Run the Clean Washer cycle every 30 days for preventive maintenance.

Troubleshooting Common Issues

If the cleaning procedure does not eliminate odor from your Whirlpool washer, consider these deeper issues:

• Persistent mold smell after cleaning usually means the outer tub (which you cannot access without disassembly) has significant biofilm. Run 3 consecutive Clean Washer cycles with Affresh to address this
• White residue on dark clothes after cleaning suggests hard water mineral deposits inside the outer tub. Add a water softening product like Calgon to your next 5 wash loads
• If the drain pump filter is damaged or cracked, order replacement WPW10730972 and install it before running additional cycles, as the cracked filter basket cannot trap debris
• F5 E2 error code appearing during the clean cycle indicates a door lock issue unrelated to cleaning. The door lock assembly (W10838613) may need replacement
• Standing water visible through the door glass after cycle completion means the drain pump is partially clogged deeper in the system than the accessible filter

When to Call a Professional

Contact a certified technician if:

• Black mold is visible behind the drum where you cannot reach it, suggesting the spider arm or outer tub seal is failing
• The washing machine produces a sewage-like (not musty) smell, indicating a drain standpipe siphoning issue that requires plumbing assessment
• You see rusty water stains or flaking inside the drum, which indicates bearing seal failure allowing grease into the wash area
• The Clean Washer cycle itself triggers error codes repeatedly, pointing to control board or sensor malfunctions

FAQ

Q: How often should I clean my Whirlpool washing machine? A: Run the Clean Washer cycle with an Affresh tablet monthly. Manually wipe the door bellow on front-load models weekly. Clean the drain pump filter every 3 months.

Q: Can I use bleach instead of Affresh tablets in my Whirlpool washer? A: Yes, you can use 1/3 cup liquid chlorine bleach in the bleach dispenser and run the Clean Washer cycle. However, Affresh tablets are specifically formulated to dissolve the type of residue that builds up in HE washers without degrading rubber seals.

Q: Why does my Whirlpool washer smell bad even with FreshHold enabled? A: FreshHold tumbles and fans clothes to keep them fresh, but it does not address mold growing in the door bellow folds or outer tub. The musty smell comes from biofilm in areas the wash water does not fully flush.

Q: Is the Load & Go dispenser causing buildup in my washer? A: The Load & Go system itself does not cause extra buildup when properly maintained. However, a stuck dispensing valve can over-dose detergent, leading to excess residue. Clean the dispenser channel monthly and verify the valve opens fully during the wash cycle.
