5 Common Reasons for Washing Machine Odors
That telltale wet dog smell or a general musty odor from your washing machine usually signals an underlying issue. Often, it’s related to hygiene and maintenance. Here are five prevalent reasons why your washing machine might smell:
1. Neglecting Regular Washing Machine Cleaning
Just like any appliance, your washing machine requires regular cleaning to function optimally and prevent problems like unpleasant odors. Over time, a cocktail of soap scum, dirt, lint, hard water minerals, and fabric softener residues can accumulate within the machine. This buildup creates a breeding ground for bacteria and grime, leading to that characteristic musty or wet dog smell.
This accumulation isn’t limited to visible areas. It can occur in various parts of the washing machine, including:
- The rubber gasket: Especially in front-load washers, this area traps moisture and debris.
- The drum: Both the inner and outer drum can harbor residue.
- Detergent and fabric softener dispensers: These compartments can become sticky and moldy.
- Around the door and lid: Areas prone to moisture and spills.
- Under the washer lid: Often overlooked during quick cleanups.
- Any area reached by wash water: Essentially, the entire internal system.
If left unaddressed, this buildup not only causes odors but can also impact washing machine performance and even transfer smells to your clothes.
Solution: Implement a Regular Cleaning Schedule
The key to preventing odor buildup is consistent cleaning. Aim to clean your washing machine monthly or approximately every 30 wash cycles. Using specialized washing machine cleaners can significantly simplify this task. Washing machine cleaner tablets are designed to dissolve and remove residue effectively, reaching areas you might miss during manual cleaning. Liquid chlorine bleach is another effective cleaning agent, known for its disinfecting and deodorizing properties. When using bleach, ensure proper ventilation and follow manufacturer instructions carefully.
2. Overusing Laundry Detergent
While detergent is essential for cleaning clothes, using too much can actually contribute to washing machine odors. Traditional, high-sudsing detergents are particularly prone to leaving behind residue.
Excess detergent doesn’t always rinse away completely during the wash cycle. It can accumulate in various parts of the washer, including the drum and filter. This trapped detergent, combined with the consistently damp environment inside the washing machine, creates a breeding ground for bacteria and mildew, resulting in a foul smell. Sometimes, this detergent buildup only becomes noticeable when running a washer maintenance cycle, highlighting the importance of proactive maintenance.
Solution: Measure Detergent Accurately
To prevent detergent buildup, precision is key. Carefully measure the detergent for each load, strictly adhering to the manufacturer’s recommendations based on load size and soil level. Using the correct amount of detergent ensures your clothes are cleaned effectively without leaving excess residue behind in your appliance.

3. Using the Incorrect Type of Detergent
Beyond quantity, the type of detergent you use also plays a crucial role in washing machine health and odor prevention. It’s vital to match your detergent to your washing machine type, particularly if you have a high-efficiency (HE) machine.
Regular detergents, designed for traditional top-loading washers, typically produce more suds than HE detergents. In HE washing machines (both top-loading and front-loading HE models), excessive suds can interfere with the wash cycle, potentially lengthening cycle times and reducing cleaning effectiveness. More importantly for odor control, these suds can contribute to residue buildup.
Solution: Identify Your Washer Type and Choose Detergent Accordingly
Most newer washing machines are high-efficiency models. Check your machine’s manual or look for the HE symbol (usually a logo with “HE”) on the machine itself to confirm. If you have an HE washer, consistently use detergents specifically formulated for high-efficiency machines. These HE detergents are designed to produce fewer suds and rinse away more cleanly, minimizing residue buildup and preventing odors. Using the right detergent, combined with regular maintenance, is crucial for keeping your washing machine smelling fresh and clean.

4. Leaving the Washer Damp for Extended Periods
Another significant contributor to washing machine odors is trapped moisture. Leaving your washing machine damp for prolonged periods after completing a wash cycle creates an ideal environment for mold and mildew growth. This is especially true in the warm, enclosed space of the washing machine drum.
Residues within the washer exacerbate this problem. If detergent or fabric softener residue is present, it can become a breeding ground for odor-causing bacteria and mold when combined with moisture. Furthermore, leaving wet clothes in the washer for too long, such as overnight, can lead to malodors transferring to the clothes themselves, sometimes requiring re-washing.
Solution: Empty the Washer Promptly and Promote Drying
To prevent moisture-related odors:
- Unload laundry immediately: Don’t leave wet clothes sitting in the washer after the cycle finishes. Transfer them to the dryer promptly.
- Leave the washer door ajar: When not in use, keep the washing machine door slightly open to allow air circulation and promote drying inside the drum. This is especially important if you won’t be using the machine for several hours or days. For homes with small children or pets, ensure this is done safely.
- Wipe down the gasket and drum: After use, particularly in front-load washers, wipe down the rubber gasket and the inside of the drum with a clean cloth to remove excess moisture.
These simple habits will significantly reduce moisture buildup and help keep your washer odor-free.
5. Drainage Problems
Improper drainage can also lead to a smelly washing machine. If water isn’t draining correctly, it can stagnate in the drum or drain lines, creating a breeding ground for bacteria and mold. Clogged drains or drain pipes are common culprits. Blockages prevent water from fully evacuating after the wash cycle, leaving behind dampness and residue.
Solution: Ensure Proper Drainage
Regularly check your washing machine’s drain system:
- Inspect the drain hose: Ensure the drain hose is not kinked, clogged, or improperly inserted into the drain pipe.
- Check for clogs: Look for any visible blockages in the drain opening or the drain pipe itself. Lint, debris, or small objects can sometimes obstruct the drain.
- Run a drain cleaning cycle: Some washing machines have a self-cleaning or drain cleaning cycle that can help flush out minor clogs.
- Professional drain cleaning: If you suspect a more significant drain blockage, consider contacting a plumber to inspect and clean the drain lines.
Ensuring proper drainage prevents water accumulation inside the washer, reducing moisture-related issues and minimizing the buildup of mold, mildew, soap scum, and odor-causing bacteria.

Why Do My Clothes Smell Like Wet Dog After Drying?
If you’ve addressed washing machine odors but still notice a wet dog smell on your dried clothes, it often points to detergent buildup within the fabric itself. When detergent isn’t fully rinsed out during the wash cycle (often due to overuse), it can remain trapped in the fibers of your clothes. This trapped detergent can then develop an odor, particularly when exposed to humidity or body heat after drying.
To prevent this, again, ensure you are using the correct type and amount of detergent for every wash load. Consider using an extra rinse cycle for heavily soiled loads or if you suspect detergent buildup is the issue.
Simple Tips for Removing and Preventing Washing Machine Odors
Fortunately, maintaining a fresh-smelling washing machine is achievable with a few simple habits and preventative measures.

1. Reduce Fabric Softener Usage
While fabric softener can make clothes feel softer and smell pleasant, excessive use can contribute to residue buildup in your washing machine. Fabric softeners are designed to leave a coating on fabric, and over time, this coating can accumulate within the washer, trapping odors and grime. Try using less fabric softener or consider alternatives like dryer balls to soften fabrics without the residue. In some cases, eliminating fabric softener altogether can significantly reduce odor problems.
2. Clean the Lint Trap Regularly
While less common in washing machines compared to dryers, some washing machine models do have lint traps or filters. Regardless of the type, it’s crucial to locate and clean any lint traps or filters in your washing machine regularly, ideally after each wash cycle or at least weekly. Removing trapped lint prevents buildup and potential odors. Refer to your washing machine’s manual for instructions on locating and cleaning the lint trap/filter.
3. Improve Laundry Room Air Circulation
Good air circulation in your laundry room can help prevent moisture buildup around your washing machine and reduce the likelihood of mold and mildew growth. Consider adding a fan to your laundry room to improve airflow. Proper ventilation helps dry out the washing machine area and keeps unpleasant odors at bay.
