Why Does My Washing Machine Smell? How to Clean It

Have you ever noticed an unusual odor coming from your washing machine? It’s ironic—something meant to clean your clothes can start smelling pretty bad itself! Over time, detergent buildup, trapped moisture, and mildew can create an unpleasant odor inside your machine. If left unchecked, this can even transfer to your laundry (yikes!). But don’t worry—getting rid of that smell is easier than you think. With a little regular maintenance and a deep clean now and then, you can keep your washer smelling fresh and working efficiently. In this blog post, Fuse HVAC and Appliance Repair helps explore why your washing machine stinks and, more importantly, how to fix it!

Common Causes of a Smelly Washing Machine

Before we dive into the cleaning process, let’s explore why your washing machine might smell in the first place. Understanding the root cause can help you prevent future odors.

1. Moisture and Mold Growth

Your washer’s dark, damp environment makes it a prime spot for mold and mildew. If you frequently close the door right after a wash, moisture gets trapped inside, leading to that unpleasant smell.

Moisture creates an ideal environment for mold growth, leading to health issues and structural damage. Proper ventilation, dehumidification, and prompt leak repairs help prevent mold infestations and maintain a healthy indoor environment.

2. Detergent and Fabric Softener Buildup

Using excessive detergent or fabric softener can result in leftover residue. Over time, this buildup turns into a breeding ground for bacteria, causing your washer to smell bad.

Detergent and fabric softener buildup can leave residue on clothes, making them feel stiff and less absorbent. It also affects washing machine performance, causing odors and clogs. Regularly cleaning the washer and using the right detergent amount helps prevent buildup.

3. Clogged Drain or Filter

A washing machine not draining properly can cause stagnant water to accumulate, which creates a foul odor. If your washer won’t start or your washing machine not spinning, a clogged drain or filter could be to blame.

A clogged drain or filter can lead to slow drainage, water backups, and potential damage. Regular maintenance, like cleaning debris and using drain strainers, helps prevent blockages. Professional plumbing services can efficiently clear stubborn clogs, ensuring smooth water flow.

4. Forgotten Laundry

Leaving wet clothes sitting in the drum for hours (or worse, overnight) can quickly lead to mildew smells. If you’ve ever found your clothes still wet after the spin cycle, this could be why.

Forgotten laundry left in the washer can lead to musty odors and mold buildup, affecting your clothes and machine. Regular maintenance and timely washer repairs prevent these issues, ensuring fresh laundry every time. Need washer repair? Schedule a service today!

How to Clean Your Smelly Washing Machine

Now that we know what’s causing the problem, let’s tackle it head-on with a deep clean! Follow these simple steps to get your washer smelling fresh again.

Step 1: Run a Hot Water Cycle with Vinegar

White vinegar is a natural disinfectant that helps break down residue and kill odor-causing bacteria.

• Set your washing machine to the highest temperature and the longest cycle.
• Add two cups of white vinegar to the drum (no detergent!).
• Let the cycle run its course.

Step 2: Scrub the Drum and Door Seal

After the vinegar cycle, give your washer a thorough wipe-down.

• Use a microfiber cloth or an old toothbrush dipped in vinegar to scrub the drum, especially around the rubber seal.
• Check for trapped debris in the folds of the seal—it’s a common hiding spot for mold and lint.

Step 3: Clean the Detergent Dispenser

The detergent tray is another hotspot for mildew and gunk.

• Remove the dispenser tray (if possible) and soak it in hot, soapy water.
• Use a small brush to scrub away residue before placing it back.

Step 4: Run a Baking Soda Cycle

Baking soda is excellent for neutralizing odors and freshening up your washer.

• Pour half a cup of baking soda directly into the drum.
• Run another hot water cycle to flush out any remaining residue.

Step 5: Check and Clean the Filter

If your washer not draining, a clogged filter could be the culprit.

• Locate the filter (usually at the bottom of the machine behind a small door).
• Remove it and rinse it under running water to clear any debris.

Step 6: Keep the Washer Dry and Fresh

Once your washer is clean, maintaining it is key to preventing future odors.

• Keep the door slightly ajar between washes to allow for better airflow.
• Wipe down the drum and seal after each use.
• Use high-efficiency detergent and avoid overloading your washer.

Preventing Future Washing Machine Odors

1. Use the Right Amount of Detergent

Too much detergent creates excess suds that trap dirt and bacteria. Always follow the manufacturer’s recommendations.

2. Clean Your Washer Monthly

Make it a habit to deep clean your washer at least once a month using vinegar and baking soda.

3. Avoid Overloading Your Washer

An overloaded machine doesn’t rinse properly, leading to detergent buildup and lingering smells.

4. Keep an Eye on Washer Error Codes

If your washer error codes pop up, don’t ignore them! They could indicate issues like drainage problems or clogged filters.

FAQs

Why does my washing machine smell even after cleaning?

If your washer still smells, check the drain hose, pump filter, and door gasket for trapped debris or standing water. Mold can also hide behind the drum.

Can I use bleach to clean my washing machine?

Yes, but use it sparingly. A cup of bleach in a hot cycle can help kill bacteria, but too much can damage rubber seals.

How often should I clean my washing machine?

For best results, deep clean your washer once a month and wipe it down weekly.

Is a front-load or top-load washer more prone to smells?

Front-load washers are more likely to develop odors because of their rubber gasket, which traps moisture.

My washing machine is not working properly—could smells be a sign of a bigger issue?

Yes, a lingering smell could indicate poor drainage, clogged filters, or mold buildup in hidden areas. If your washer is not spinning or your clothes come out soaking wet, schedule a repair.
