Clothes washer smells can be a real nuisance, but the good news is that they're often easy to fix. A buildup of detergent residue, fabric softener, and mold can cause musty odors in your washer.
Regular cleaning is key to preventing these smells. In fact, it's recommended to clean your washer every 1-3 months, depending on usage.
One simple trick to reduce odors is to run a cleaning cycle with a cup of white vinegar. This helps dissolve mineral deposits and remove any lingering detergent residue.
Additionally, leaving the washer door open after use can help speed up the drying process and prevent moisture buildup, which can contribute to mold growth.

Why Do Clothes Washers Smell?
Clothes washers can stink for a variety of reasons, including detergent overload, which leaves behind a residue that traps moisture and creates a perfect environment for bacteria to grow.
Using too much detergent is a common mistake that can lead to buildup and bad smells. Always follow the recommended dosing instructions for your washer's manufacturer.
Front-load washers are particularly prone to holding onto water in door seals and gaskets, creating a moist environment that fosters mold and mildew growth.
Mold and mildew growth can cause a musty, damp scent, while bacteria buildup can lead to sour or sewage-like odors. These smells can be caused by residual detergent, fabric softener, or stagnant water left in the machine.
A dirty lint filter can also contribute to bad smells in your washer. Regularly cleaning the lint filter can help prevent this problem.
Here are some common reasons your washing machine might smell:
- Mold and mildew growth
- Bacteria buildup
- Detergent and fabric softener residue
- Drainage problems
- Plumbing issues
Some smells, like a rotten egg or sewage smell, might not be coming from the washer itself but could be due to plumbing issues.
Common Causes of Smells
A musty odor coming from your washing machine is usually caused by moisture and detergent or fabric softener residue buildup. This is especially true for high-efficiency machines that use less water, leaving behind soap scum that traps bacteria.
Using too much detergent or fabric softener than recommended can also lead to buildup and a bad washing machine smell. Always follow dosing instructions to avoid excess residue.
Leaving the door or lid closed between washes can promote mold growth, which contributes to the smell. Regular cleaning and leaving the door open can help prevent this.

Problem: Rotten Eggs
A rotten egg smell coming from your washing machine is no joke. It's a sign that microorganisms have built up and released hydrogen sulfide gas, and deep cleaning is usually the solution to this problem.
However, it's essential to rule out other potential causes, such as a natural gas leak or a sewer issue. If you have a gas dryer, the smell may be the result of a leak in the dryer supply line and not your washer.
Here are some steps to help you identify the source of the smell:
- Turn off the gas supply valve to the dryer for now.
- Open a window to ventilate the area.
- Check if the smell persists after taking these precautions.
If the smell persists and you're confident it's not the dryer, it's likely due to a plumbing issue causing sewer gas to enter the laundry room. In this case, you'll want to pull the washing machine away from the wall and pull the drainpipe out of the vertical standpipe to investigate further.
Take a cautious sniff to determine if the odor is coming from the drainpipe. If it is, you may have a failing or clogged washer P-trap, clogged washer vent pipe, or clogged drain.
Maintaining a Fresh Clothes Washer
Using the right amount of detergent is crucial to prevent buildup and mildew. Too much soap can leave behind a residue that traps moisture and bacteria.
Leave the washer door open after every load to give the drum a chance to dry out and prevent moisture from sitting inside. This simple habit can make a big difference in keeping odors away.
Wipe the gasket and drum dry once you're finished with each load to stop mildew from forming in hard-to-reach areas. It only takes a few seconds to do this.
Run a cleaning cycle every month with hot water and vinegar or a store-bought washer cleaner to flush out detergent residue and grime. This routine can help prevent buildup and mildew from becoming a problem.
Here are some additional tips to keep your washer in good shape:
- Use the recommended dose of detergent to prevent buildup.
- Leave the washer door open after every load.
- Wipe the gasket and drum dry once you're finished.
- Run a cleaning cycle every month.
- Skip fabric softener and try vinegar as a natural alternative.
Remember to clean the drain pump filter and empty the drain tube regularly to prevent unwanted odors. This is especially important for front-loaders, which may have a filter and drain tube located on the bottom front of the washer.

Cleaning and Sanitizing
Cleaning your washing machine regularly is crucial to prevent the buildup of residue and odors. You can use a variety of cleaning solutions, such as baking soda or bleach, to sanitize your machine.
For a natural approach, try mixing baking soda and vinegar. Add 1/4 cup of baking soda to the washer drum and 2 cups of white vinegar to the detergent dispenser. Run a hot wash cycle without laundry to break down residue and eliminate odors.
If you prefer to use bleach, add 1/2 cup to the bleach dispenser for front-loaders or 1 cup directly to the washer drum for top-loaders. Run a long, hot wash cycle, and remember to never mix bleach with other household cleaners.
To prevent washer smells from coming back, run a service wash cycle about once a month. This will help eliminate bacteria and odors. Always ensure your washing machine is empty before starting a service wash.

Like Mold or Mildew
If your washing machine smells like mold or mildew, it's likely due to the growth of microorganisms on the drum or gaskets.
Front-load washing machines are especially prone to this problem because they create an ideal environment for mildew, mold, and bacteria to grow.
Heat, moisture, and detergent or fabric softener residue all contribute to this issue.
To clean the mold smell, start by wiping down the interior, gasket, and door with a mixture of warm water and vinegar.
This will kill the microorganisms that are causing the odor.
Run a hot wash cycle with 2 cups of vinegar to sanitize the interior of the machine.
This will help eliminate any remaining microorganisms.
After the hot wash cycle, run another hot cycle with 1/2 cup of baking soda to neutralize any remaining odors.

If you suspect a sewage issue, start by checking the drainpipe and P-trap for blockages. Pull the washing machine away from the wall and remove the drainpipe from the vertical standpipe to investigate.
Here are some common causes of sewage issues in washing machines:
- A failing or clogged washer P-trap
