Narrow it down
What this symptom can tell you
The odor is musty or sour
Moisture, detergent residue, soil, or buildup in owner-cleanable areas may be involved.
The odor resembles a drain or sewer
Stale water, a drain-hose installation issue, or nearby plumbing may be contributing.
The odor is hot, electrical, rubber, or burning
Stop using the washer, disconnect power if safe, and arrange service rather than running a cleaning cycle.
These patterns narrow the next check; they do not confirm a failed part. Use the exact model number and any displayed code before ordering parts or authorizing repair.
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.

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
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

Most common categories
Possible causes to consider
- Moisture left in the drum, dispenser, gasket folds, or filter area.
- Too much detergent or repeated low-temperature cycles that leave residue.
- A pump filter or drain area listed for owner cleaning in the manual.
- A drain hose or household drain condition that allows stale water or odour backflow.
- An overheating electrical or mechanical issue when the smell is burning or hot.
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.

Common questions
Washing machine smells bad: FAQs
Should I leave the washer door open?
If the manufacturer allows it and the area is safe for children and pets, leaving the door or lid slightly open can help owner-cleanable surfaces dry.
Can I mix bleach and vinegar to clean a washer?
No. Never mix cleaning chemicals. Use only the washer-cleaning product and cycle approved in the manual.
Why does the smell return after one cleaning cycle?
Residue in the dispenser, gasket, filter, drain path, or household plumbing may remain. Follow the complete model cleaning routine and correct detergent use.
