Quick answer
Check the detergent drawer and filter for clogs. Ensure the load is balanced and not overloaded. Run a cleaning cycle with hot water and vinegar if needed.
Confirm the symptom
- Clothes are still dirty after a full wash cycle
- Stains or odors remain despite using detergent
- Washer completes cycle but clothes aren't clean
Tools and prep
- Screwdriver (if needed for access panels)
- Bucket for water or cleaning solutions
- Rubber gloves for handling dirty parts
- White vinegar or washing machine cleaner
- Soft brush or old toothbrush for scrubbing
- Turn off power to the washer at the circuit breaker
- Shut off water supply to the washer
Step-by-step troubleshooting
- Check Detergent UsageDo: Verify the correct amount and type of detergent is being used.Observe: Detergent may not be dissolving properly if too much is used or if the wrong type is selected.Means: Improper detergent use can prevent effective cleaning.Next: If incorrect, adjust detergent amount or switch to a high-efficiency (HE) formula if needed.
- Inspect Detergent DrawerDo: Remove and clean the detergent drawer and its compartments.Observe: Clogged dispensers can prevent detergent from reaching the drum.Means: A dirty or clogged drawer may be the cause of poor cleaning.Next: Clean the drawer thoroughly and reinsert it.
- Check Washer FilterDo: Locate and clean the washer’s filter (usually at the front or bottom).Observe: A clogged filter can restrict water flow and cleaning performance.Means: Blocked filters prevent proper water circulation.Next: Clean or replace the filter if damaged.
- Run a Cleaning CycleDo: Run a hot water cycle with 2 cups of white vinegar or a washing machine cleaner.Observe: The washer should clean itself and remove buildup.Means: Mineral deposits or mold can reduce cleaning effectiveness.Next: Repeat if necessary and check if cleaning improves.
- Verify Load BalanceDo: Ensure the load is evenly distributed and not overloaded.Observe: An unbalanced load can prevent proper agitation or spinning.Means: Improper load balance affects cleaning performance.Next: Redistribute or reduce the load and restart the cycle.
- Check Water TemperatureDo: Ensure the washer is using hot water for the cycle when appropriate.Observe: Cold water may not activate detergent or remove stains effectively.Means: Incorrect water temperature reduces cleaning power.Next: Adjust the water temperature settings if needed.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Clogged detergent drawer or filter Prevents detergent from dissolving or water from flowing properly. | Common | Easy | Detergent drawer, filter |
| Incorrect detergent type or amount Using too much or the wrong type of detergent can leave residue and reduce cleaning power. | Common | Easy | High-efficiency (HE) detergent |
| Mineral buildup or mold in the washer Buildup in the drum or seals can reduce cleaning effectiveness and cause odors. | Common | Easy–Medium | Washing machine cleaner or vinegar |
| Unbalanced or overloaded laundry Overloading or uneven distribution prevents proper agitation and rinsing. | Sometimes | Easy | None |
| Faulty water inlet valve A damaged valve can restrict water flow, leading to poor cleaning. | Sometimes | Medium | Water inlet valve |
| Worn or damaged agitator (top-loaders) or drum (front-loaders) A broken agitator or drum can prevent proper movement of clothes during the cycle. | Rare | Hard | Agitator or drum assembly |

FAQ
Can I use regular detergent in a high-efficiency (HE) washer?
No, regular detergent can create excess suds and leave residue. Always use HE detergent in HE washers.
How often should I clean my washing machine?
Run a cleaning cycle with vinegar or a machine cleaner every 1–2 months to prevent buildup.
Why does my washer smell even after cleaning?
Persistent odors may indicate mold in the drum or seals. Clean thoroughly and ensure the door is fully open to dry.
Is it normal for clothes to still have some stains?
Pre-treat tough stains before washing. If stains persist, the washer may not be functioning properly.
Can hard water affect cleaning performance?
Yes, hard water can leave mineral deposits. Use a water softener or washing machine cleaner to address this.
