Washing Machine Odour: A Material-Safe Cleaning Routine

Identify the washing machine odour before cleaning

A musty smell may come from damp residue in a front-loader’s door gasket, detergent left in a dispenser, or moisture around a top-loader’s lid rim. Start by locating the smell: open the empty machine, inspect the accessible surfaces, and check whether the odour is strongest at the dispenser, door opening, or drum. Note any standing water or poor drainage.

This routine covers accessible washer surfaces and a manufacturer-approved cleaning cycle. It does not cover electrical components, plumbing repairs, hidden mold inside walls or cabinets, or dismantling the machine. Front-load and top-load washers have different seals and access points; use only the steps that apply to yours. Rubber gaskets, painted or stainless-steel drums, plastic dispensers, and exterior finishes may have different care requirements, so the model’s manual takes priority over general cleaning advice.

A burning or electrical smell, a leak, or water that remains in the drum after a cycle is not a routine cleaning problem. Stop using the washer and seek service. If you see extensive growth outside the machine or suspect a building moisture problem, address that separately; cleaning the drum will not fix its source.

Prepare the washer and supplies

Remove all laundry. Find the washer manual or the manufacturer’s instructions for its clean-washer cycle, dispenser removal, and pump-filter access. Gather a soft cloth or sponge, warm water, a small amount of mild dish soap for parts the manual allows you to wash, and dry towels. Have a washer-cleaning product on hand only if the manufacturer specifies or permits one. Check its label for the correct dose and precautions.

Unplug the machine before wiping accessible areas by hand. If your model has a user-serviceable pump filter, have a shallow tray and towels ready; opening it can release water. Do not force out a dispenser or open a filter that the manual does not identify as user-accessible. Do not combine cleaners. In particular, never mix bleach with vinegar, other acids, or ammonia. If switching products, rinse as their labels direct first.

Step-by-step routine

1. Wipe the door opening or lid rim. On a front-loader, gently pull back the accessible folds of the door gasket and remove lint, hair, and trapped debris. Wipe the gasket with a damp cloth. Where the manual permits mild soapy water, use it sparingly, then wipe away residue with a clean damp cloth. Do not use sharp tools, abrasive pads, or a cleaner the manufacturer warns against. On a top-loader, wipe the lid rim and other accessible splash areas instead.

2. Clean the detergent dispenser. Remove the drawer only if the manual says it is removable. Empty residue, wash the permitted plastic pieces with warm water and mild dish soap, and use a soft cloth to clean accessible buildup in the drawer opening. Rinse and dry the pieces before reinstalling them. Do not pour water into an electrical housing or force a brush into hidden channels.

3. Check the pump filter, if your model has a user-accessible one. Follow the manual’s draining and opening sequence exactly. Catch released water, remove loose debris, and refit the filter securely. Skip this step when the filter is not identified as user-serviceable. A machine that repeatedly fails to drain needs troubleshooting, not repeated cleaning cycles.

4. Run the specified cleaning cycle. Plug the washer back in after reassembling all parts. With the drum empty, select the manufacturer’s clean-washer cycle and add only the product and amount its instructions call for. Some models specify a particular cleaner or procedure; do not substitute vinegar, bleach, or an extra product on your own. If there is no dedicated cycle, follow the manual’s alternative rather than guessing at a temperature or chemical dose.

5. Dry and reassess. When the cycle ends, wipe the drum opening, gasket or lid rim, and dispenser area dry. Leave the door or lid and dispenser slightly open to air out only where the manufacturer permits and where children and pets cannot access the machine. Smell the empty washer again after it has dried, then check the next load for lingering odour.

When to stop or get help

Stop if a cleaner causes irritation, if a part resists removal, or if you find damaged rubber, leaks, or persistent standing water. Rinse accessible surfaces as the product label directs and ventilate the area. If you accidentally mix cleaning chemicals and notice strong fumes, leave the area and follow local poison-control or emergency guidance; do not lean into the machine to investigate.

If the odour returns quickly despite cleaning and drying, check the manual’s guidance on detergent amount, cycle selection, and drainage. A persistent sewage-like smell or poor draining can point to a drain or plumbing issue that wiping the drum will not resolve. Arrange qualified service when the source is inaccessible or the machine is malfunctioning.

FAQ

Can I use vinegar to remove washing machine odour?

Use only cleaning agents permitted by your washer manufacturer. Vinegar is an acid and must never be mixed with bleach. A manufacturer’s specified cleaning cycle and product give you a clearer, model-appropriate starting point than a general-purpose vinegar recipe.

Do I need to disinfect the washer?

Not for an ordinary musty smell. Cleaning removes accessible residue; disinfection is a separate process with product-specific label directions. If a particular contamination calls for disinfection, check the washer manual and the disinfectant label for compatibility and use instructions.

How can I keep the smell from coming back?

Promptly remove finished laundry, clear visible residue from the gasket or lid rim, and let accessible areas dry when it is safe to leave them open. Follow the manual’s detergent dosing and maintenance schedule. Repeated odour despite those steps may indicate a drainage or service issue.

Source note

CDC guidance distinguishes routine cleaning from disinfection and emphasizes following product directions. EPA guidance identifies moisture control as central to addressing mold and recurring dampness. Whirlpool’s washer-cleaning guidance informs the maintenance approach here, but procedures vary by model: your own washer manual and cleaner label govern removable parts, cycle settings, and chemical compatibility.
