Why your washing machine smells — and how to fix it

If clean laundry comes out smelling musty, the problem is usually the machine, not the clothes. Here is how to fix it and keep it from coming back.

What causes the smell

Every load leaves a little behind: detergent and softener residue, body oils, lint and hard-water minerals. That film collects in places you never see, like under the drum, in the gasket and in the dispenser drawer. Add warm, damp air and it becomes the perfect spot for odor-causing bacteria and mildew.

Front-loaders tend to smell more, because their airtight door seal holds moisture in. High-efficiency machines also use less water, so residue rinses away less easily.

How to clean your washer, step by step

1. Wipe the door gasket, folds included, with a damp cloth to remove hair, lint and slime.
2. Pull out the detergent drawer if it is removable, and rinse it in warm water.
3. Add a washing machine cleaner to the empty drum as directed on the package.
4. Run the hottest, longest cycle your machine offers, with no clothes inside.
5. Wipe the drum and gasket dry, and leave the door open to air out.

Habits that keep it fresh

• Leave the door and detergent drawer open after each load so moisture can escape.
• Move wet laundry to the dryer promptly.
• Use the right amount of detergent. More is not cleaner, it just leaves more residue.
• Run a cleaning cycle about once a month, more often with hard water or heavy use.
• Clean the drain pump filter if your machine has one. Check your manual for where it is.

Always check your manual

Many washers have a dedicated "clean washer" or "tub clean" cycle. Use it when you have one, and follow the manufacturer's guidance for your model.
