A washer can smell unpleasant even when its drum looks spotless. The source is often moisture or laundry-product residue hiding in the gasket, dispenser, filter or drain area.
Quick answer: A musty washer usually needs its gasket or lid area, detergent dispenser, user-accessible filter and drum-cleaning cycle checked. Remove wet laundry promptly, use the recommended amount of detergent and let the washer dry between loads. If the smell is electrical, burning, strongly sewage-like or returns with poor drainage, stop using the machine and investigate the installation or arrange service.
What Does the Smell Seem Like?
Odor descriptions are not a diagnosis, but they can suggest where to look.
- Musty or damp: Check the gasket, lid, dispenser and filter for moisture and residue.
- Sour: Look for forgotten laundry or excess detergent and softener.
- Sewage-like: The odor may be coming through the drain hose, standpipe or nearby plumbing rather than from the drum itself.
- Burning, hot plastic or electrical: Stop the cycle, unplug the washer if it is safe to do so, and arrange qualified service. Do not try to cover this odor with cleaner.
7 Common Reasons a Washing Machine Smells
1. Moisture Is Trapped After the Cycle
A closed door or lid slows drying. Front-load machines can hold moisture in the rubber gasket folds.
2. Too Much Detergent Is Leaving Residue
Excess detergent may not rinse away completely, leaving a film that traps soil and odor. Follow the detergent label and washer manual, especially for high-efficiency machines.
3. Fabric Softener Has Built Up
Liquid softener can coat the dispenser and other wet surfaces. Remove the dispenser only as directed and rinse accessible parts with warm water.
4. The Door Gasket or Lid Area Is Dirty
Hair, lint and water can collect under a front-load gasket. On a top-loader, residue may sit around the rim and lid. A drum cycle may not fully reach these places.
5. The Filter or Drain Area Needs Attention
Some front-load washers have a user-accessible drain-pump filter. Trapped debris or standing water can contribute to odor. Check the manual before opening any panel; water may be released.
6. Wet Laundry Was Left in the Drum
Damp clothes can make even a clean washer smell sour. Remove finished loads promptly and let the drum dry.
7. The Drain Hose or Plumbing Is the Source
If the washer smells like sewage while draining, check the hose and standpipe against the installation instructions. A blocked drain or plumbing problem may need a professional.
How to Remove Washing Machine Odor
Work from visible, user-accessible areas toward the cleaning cycle.
- Empty and air out the washer. Remove clothing and debris. Open the door or lid when household safety allows.
- Wipe the gasket, door, lid and rim. Use a soft damp cloth and avoid scraping the seal.
- Clean the detergent dispenser. Follow the manual for removal. Rinse away accessible detergent and softener residue before reinstalling it.
- Check the filter if the manual identifies it as user-accessible. Never force open a service panel.
- Run the approved empty cleaning cycle. Select Clean Washer, Tub Clean or the equivalent program. A pre-measured option such as KLEKPUE Washing Machine Cleaner Tablets – 12 Pack goes directly in the empty drum or basket according to its directions, not in the detergent drawer.
- Wipe and dry after the cycle. Remove loosened residue and run an extra rinse if directed.
Do not put clothes in the machine during a washer-cleaning cycle. Do not mix a cleaner tablet with bleach, vinegar, ammonia or another cleaner unless both the cleaner label and washer manufacturer explicitly approve the combination.

Front-Load vs. Top-Load Odor Checks
For a front-load washer, check the lower gasket folds, dispenser, user-accessible pump filter and inside of the door.
For a top-load washer, inspect the lid, rim, removable dispensers and safely reachable agitator or impeller areas. Remove components only when the manual directs it.
How to Keep the Smell From Coming Back
- Remove wet laundry soon after the cycle finishes.
- Measure detergent and fabric softener instead of pouring by eye.
- Leave the door or lid and dispenser slightly open until dry when it is safe around children and pets.
- Wipe visible moisture and residue before it hardens.
- Run the washer's approved maintenance cycle on the schedule in its manual or cleaner directions.
- Check pockets and remove lint, hair and small objects from accessible areas.
When Cleaning Is Not Enough
Arrange professional help if the washer leaks, drains poorly, shows repeated error codes or gives off a burning or electrical smell. Service may also be appropriate when odor returns immediately after approved cleaning.
Frequently Asked Questions
Why does my washer smell worse after a cleaning cycle?
The cycle may have loosened residue that needs wiping, or the source may be the gasket, dispenser, filter or drain. Follow any rinse directions, dry the washer and inspect those areas.
Why does my washing machine smell only when it drains?
That timing can point toward the drain hose, standpipe or plumbing. Check the hose position and seek help if drainage is slow or the odor persists.
Can I use a washing machine cleaner tablet with clothes?
No. Use washer cleaner in an empty machine during a separate maintenance cycle.
How often should I clean my washing machine?
Start with the schedule in your owner's manual. The KLEKPUE package recommends monthly cleaning, while a busy household or a washer in a humid area may need more frequent inspection.
Find the Source, Then Build a Routine
Cleaning the drum alone may not solve a washer odor. Check the damp, hidden areas first, use one approved cleaning method and let the machine dry. For a simple pre-measured maintenance option, review the directions for KLEKPUE washing machine cleaner tablets.
