General owner-safe guideUpdated July 2026

Washing machine smells bad

A musty, mildew, sour, or stale-water odor returns after washing.

Start hereEmpty the washer and identify the type of odor before cleaning.

Try these checks in order

Controls, access points, and normal behaviour differ by model. Stop when a step does not match your appliance or official manual.

  1. 1

    Let the washer dry

    Remove the load, wipe visible moisture, and leave the door or lid open when the appliance is not in use and it is safe to do so.

    What you want: A clear result without opening the appliance or bypassing a safety system.
  2. 2

    Clean the gasket and dispensers

    Wipe only owner-accessible surfaces with the cleaner and method listed in the manual. Remove trapped lint, hair, and detergent residue.

    What you want: A clear result without opening the appliance or bypassing a safety system.
  3. 3

    Run the manufacturer cleaning cycle

    Use the washer-clean or tub-clean cycle and only the cleaner type and amount allowed by the manual. Do not mix cleaning chemicals.

    What you want: A clear result without opening the appliance or bypassing a safety system.
  4. 4

    Check an owner-accessible pump filter

    On models that provide a user filter, follow the manual, prepare for water, and reseal it carefully.

    What you want: A clear result without opening the appliance or bypassing a safety system.
  5. 5

    Review detergent use

    Use high-efficiency detergent when required and avoid routinely using more than the product and washer instructions specify.

    What you want: A clear result without opening the appliance or bypassing a safety system.

Stop and arrange help when

  • The smell is electrical, hot-plastic, smoky, or accompanied by heat.
  • The odor resembles sewer gas and is strongest at the household drain.
  • Visible mold extends behind panels or into inaccessible parts.
  • Water is leaking near wiring, the outlet, or the controls.

If the problem remains

Record the exact model, symptom, any code, and the checks completed. Use the official manual and recall search before authorizing service.
