Stinky Washing Machine? A Material-Safe Cleaning Routine

Where is the stinky washing machine smell coming from?

Start with the empty washer. Smell near the drum, detergent dispenser, and, on a front-loader, the folds of the door gasket. Look for detergent buildup, trapped lint, standing water, or visible growth. Odor can have more than one source, so a drum-cleaning cycle alone may not reach residue in a dispenser or gasket.

This routine covers accessible interior surfaces of a household washer. Front-load door gaskets and top-load lid openings differ; clean only the parts your machine has. Drum finishes, removable dispensers, filters, and approved cleaning products also vary by model. Your owner’s manual takes priority over general advice here. This is not a repair procedure for plumbing, pumps, bearings, electrical components, or leaks. It does not treat extensive mold in walls or other building materials near the machine.

If the smell resembles sewage, burning, or hot electrical insulation, do not assume ordinary washer residue is the cause. Stop using the machine and arrange the appropriate plumbing or appliance assessment.

Prepare the washer and supplies

Remove all laundry. Read the manual’s instructions for its Clean Washer, Tub Clean, or equivalent cycle, including whether it calls for an empty drum, a specific cleaning product, or a particular dispenser compartment. Gather soft cloths, a small soft brush, warm water, and mild dish soap for accessible parts if the manual permits it. Have a dry cloth ready for the final pass.

Choose one cleaning approach for the drum: the washer manufacturer’s specified cleaner and cycle. Do not add vinegar, bleach, detergent, and a washer-cleaning tablet together. If your manual permits bleach, follow both the machine instructions and the bleach label exactly. The CDC warns against mixing household bleach with other cleaners or disinfectants. Ventilate the area as directed on the product label and keep children and pets away from products and an open washer.

Before removing any component, confirm that the manual describes how to release and reinstall it. Never pry a dispenser or pull a gasket out of place. If your machine has a drain-pump filter, treat it as a separate, model-specific maintenance task: opening it can release water.

Step-by-step cleaning routine

1. Inspect the empty drum and opening. Remove loose lint, hair, or forgotten items by hand. Wipe visible residue from the door or lid opening with a damp cloth. Avoid abrasive pads, which may damage finishes or gasket surfaces.

2. Clean an accessible dispenser. If the manual says the drawer is removable, release it as directed. Wash accessible residue with warm water and a little mild dish soap, using a soft brush for corners. Rinse, dry, and reinstall it securely. If the dispenser is fixed, wipe only the surfaces you can reach without forcing parts apart. Do not pour water into controls or openings not identified for washing.

3. Wipe the front-load gasket, if present. Gently fold back each accessible section and remove lint or debris. Wipe the folds with a cloth lightly dampened with warm, soapy water, then use a clean damp cloth to remove soap residue. Dry the folds with a separate cloth. Do not scrub aggressively, pull the gasket from its mounting, or apply a chemical that the manual prohibits. Check for splits or areas that no longer seal properly.

4. Run the designated cleaning cycle. With the drum empty, select the manufacturer’s washer-cleaning cycle and use only the product and amount its instructions allow. If the machine has no designated cycle, consult its manual for the recommended alternative rather than guessing a water temperature or adding extra chemicals. Let the cycle finish; do not interrupt it to add another cleaner.

5. Check and dry. When the cycle ends, wipe any remaining moisture or loosened residue from the drum opening, dispenser area, and gasket. If residue remains, consult the manual about repeating the cleaning cycle. Leave the door or lid and dispenser open when the machine is idle, provided they will not create a safety hazard in your household, so accessible surfaces can dry.

Wash cleaning cloths afterward. Before the next load, confirm that the dispenser is seated correctly and that no cloth or loose item remains in the drum.

Keep the smell from returning

Measure laundry detergent according to its label and your load and water conditions; more detergent is not necessarily better. Use only products compatible with your washer. Remove finished laundry promptly, wipe persistent moisture from accessible gasket folds, and follow the manual’s schedule for its cleaning cycle. Check the dispenser periodically for buildup. These habits address residue and moisture without relying on a stronger chemical mixture.

When to stop and seek help

Stop if you see leaking water, a torn gasket, a damaged cord, unusual heat, or a filter you cannot safely open according to the manual. Arrange appliance service rather than dismantling the machine. If odor returns soon after a complete cleaning, persists alongside standing water, or seems strongest at the drain, a drainage or installation problem may need assessment.

Visible growth beyond accessible washer surfaces calls for a different evaluation. EPA guidance emphasizes addressing the moisture source when dealing with mold; surface cleaning alone will not resolve an ongoing water problem.

FAQ

Can I use vinegar and bleach in separate steps?

Do not combine them or add one to a machine that may still contain the other. This routine does not require either product. Follow your washer manual and the chosen cleaner’s label instead.

Should I clean the drain-pump filter?

Only if your model has a user-serviceable filter and its manual gives instructions. Some filters release retained water when opened. Cleaning the drum, gasket, and dispenser does not require opening a filter.

Why does the washer smell again after a cleaning cycle?

Residue in an uncleaned dispenser or gasket, retained moisture, or a drainage issue may still be present. Recheck accessible areas and the manual’s maintenance guidance. If the smell quickly returns despite cleaning and drying, seek service rather than repeatedly adding chemicals.

Whirlpool’s washer-cleaning guidance informs the model-dependent drum, dispenser, and gasket steps. CDC guidance supports the bleach-mixing warning. EPA mold guidance supports addressing an underlying moisture problem when growth persists. These sources do not replace the care instructions for your specific machine.
