A washing machine should help your clothes smell fresh, but sometimes the machine itself can develop a musty or unpleasant odor. This usually happens when moisture, detergent residue, dirt, and bacteria build up inside the machine.
Fortunately, preventing washing machine odor doesn't require much effort. A few simple habits can keep your machine fresher and your laundry smelling cleaner.
Why Does a Washing Machine Smell?
Washing machines stay damp for long periods, especially when the door or lid remains closed after a cycle. Detergent and fabric softener can also leave residue behind, which can combine with dirt and create unpleasant smells.
Common causes include:
Moisture trapped inside the machine
Mold and mildew buildup
Too much detergent
Dirty detergent drawers
Residue around the door seal
A dirty washing machine drum
Leaving wet clothes inside for too long
Poor ventilation
1. Leave the Door or Lid Open
One of the easiest ways to prevent odor is to leave the washing machine door or lid slightly open after each wash.
This allows moisture to escape and helps the inside of the machine dry. If you have children or pets around the machine, make sure the door is left open only when it is safe to do so.
2. Remove Wet Clothes Promptly
Don't leave wet laundry sitting inside the washing machine for hours.
Wet clothes can quickly develop a musty smell, especially in a closed drum. Move them to the dryer or hang them up as soon as possible after the cycle finishes.
3. Don't Use Too Much Detergent
More detergent doesn't necessarily mean cleaner clothes.
Excess detergent can leave a sticky residue inside the drum, hoses, and detergent drawer. Over time, this residue can contribute to unpleasant odors.
Follow the detergent manufacturer's recommended amount and adjust it according to your load size and water conditions.
4. Clean the Detergent Drawer
The detergent drawer can collect leftover detergent, fabric softener, and moisture. This buildup can eventually develop mold and a bad smell.
Remove the drawer regularly, rinse it with warm water, and scrub stubborn residue with an old toothbrush.
For most households, cleaning it about once a month is a good habit.
5. Wipe the Door Seal
Front-loading washing machines have a rubber door seal that can trap hair, lint, dirt, water, and small objects.
After washing, inspect the folds of the seal and wipe away any visible debris or moisture with a clean cloth.
Cleaning this area regularly can make a big difference in preventing musty smells.
6. Run a Washing Machine Cleaning Cycle
Even when your clothes look clean, residue can accumulate inside the washing machine.
Run the machine's dedicated drum-clean or tub-clean cycle if it has one. If your machine doesn't have a cleaning program, follow the manufacturer's instructions for cleaning the drum.
Use a washing-machine cleaner if recommended by the manufacturer, and avoid mixing different cleaning chemicals.
7. Clean the Filter
Many washing machines have a drain or pump filter that can collect lint, hair, coins, and other debris.
A dirty filter can contribute to drainage problems and unpleasant smells.
Check your owner's manual to find the filter and learn how to clean it safely. Before opening a drain filter, be prepared for water to come out.
8. Avoid Constantly Washing at Very Low Temperatures
Cold and low-temperature washes are useful for many types of laundry, but relying exclusively on them can allow more residue to accumulate inside some machines.
Occasionally running a hotter maintenance wash, if permitted by your machine's manufacturer, can help keep the machine cleaner.
Always follow the care instructions for your washing machine and laundry.
9. Keep the Machine's Surrounding Area Ventilated
Good ventilation isn't just important inside the drum.
If the washing machine is installed in a small, damp, poorly ventilated space, moisture can linger around it and contribute to musty smells.
Keep the area around the machine reasonably dry and well ventilated.
10. Don't Overload the Machine
Overloading can prevent clothes from moving and rinsing properly.
It can also leave more moisture and detergent residue behind. Follow the manufacturer's recommended load capacity and avoid packing clothes tightly into the drum.
What If Your Washing Machine Already Smells?
If your machine already has an odor, start by removing any wet laundry and inspecting the detergent drawer, door seal, and filter.
Clean visible residue and run the manufacturer's recommended cleaning cycle. If the smell persists, there may be a drainage or plumbing problem that requires further investigation.
If the machine isn't draining properly, leaves standing water, or continues to smell despite thorough cleaning, consider contacting a qualified appliance technician.
A Simple Washing Machine Freshness Routine
You don't need to deep-clean your washing machine every day. Try this simple routine:
After every wash:
Remove clothes promptly.
Leave the door or lid open when safe.
Wipe away excess moisture if necessary.
Once a week:
Check the door seal for dirt and trapped debris.
Wipe visible residue from the machine.
Once a month:
Clean the detergent drawer.
Clean the filter according to the manufacturer's instructions.
Run a drum-cleaning cycle or maintenance wash as recommended.
Final Thoughts
Preventing washing machine odor is mostly about controlling moisture and residue. Leaving the door open, removing wet clothes promptly, using the right amount of detergent, and regularly cleaning the drawer, seal, filter, and drum can keep unpleasant smells under control.
A few minutes of maintenance each week can help your washing machine stay fresher—and help your freshly washed clothes smell the way they should.
