How to Fix a Smelly Washing Machine: A Comprehensive Guide
Opening your washing machine and being greeted by a foul odor is never pleasant. Washing machines are meant to clean your clothes, but over time, they can develop musty, sour, or rotten smells. These odors can end up on your laundry, too. The good news? You can easily tackle and prevent a smelly washing machine with the right steps and a bit of consistency.
Let’s break down why this problem happens, how to get rid of the smell, and how to keep your washing machine fresh in the future.
Why Washing Machines Smell
Before you can fix the situation, it helps to know why your washing machine smells bad in the first place. Here are the most common reasons:
- Moisture and Residue: After every wash, some moisture remains. Combine that with soap scum, fabric softener residues, and fibers from clothes, and you have the perfect breeding ground for mold and bacteria.
- Low-Temperature Washes: Most modern washes happen at lower temperatures, which can leave behind bacteria and detergent residues.
- Sealed Doors: When washers—especially front-loaders—are closed tightly after use, they trap moisture inside.
- Dirty Seals and Drains: Rubber door seals and draining pipes can hold onto lint, threads, and gunk.
- Skipped Cleanings: Like any hardworking appliance, your washing machine needs routine cleaning to operate at its best.
Step-By-Step: How to Clean and Deodorize Your Washing Machine
Follow these steps to banish bad odors and restore freshness to your washer, whether you have a front-loader or a top-loader.
1. Clean the Drum
- Mix 1/4 cup of baking soda with 1/4 cup of water.
- Add this mixture to the machine’s detergent container.
- Pour 2 cups of white vinegar directly into the drum.
- Run the washer on the hottest and longest setting.
This process helps break down soap scum, mineral deposits, mold, and bacteria that build up over time.
2. Clean the Rubber Seals and Door
- Open the washing machine door.
- Gently pull back the rubber gasket (seal) and inspect for grime, mold, or hair.
- Wipe the entire seal with a cloth or sponge soaked in a solution of water and white vinegar (equal parts).
- Use an old toothbrush to scrub away stubborn spots.
Don’t be surprised if you find plenty of hidden debris—it’s a common hiding spot for gunk!
3. Clean Soap Dispensers and Drawers
- Take out detergent dispensers or drawers, if removable.
- Wash them in warm, soapy water. Use a toothbrush to scrub corners and crevices.
- Allow them to dry fully before putting them back.
Leaving these parts wet can encourage mold regrowth.
4. Check and Clear the Filter
- Locate your washing machine filter—it’s often found at the bottom front of the machine (check your user manual if unsure).
- Remove the filter and rinse it under hot running water.
- Remove lint, coins, or small objects.
- Reinsert the filter carefully.
A clogged filter not only smells but can affect washing performance.
5. Run a Maintenance Wash Regularly
- Once a month, run a hot wash cycle (90°C or hottest setting) with no laundry in the machine.
- For extra cleaning, add a washing machine cleaner or a cup of baking soda and vinegar directly to the drum.
6. Dry Out After Every Wash
- After each laundry session, leave the washing machine door and detergent drawer slightly open.
- Allowing air to circulate and dry the drum and seals helps prevent mold and stale odors.
Practical Tips and Best Practices
Want to keep your washer smelling clean? Stick to these habits:
- Use the Right Amount of Detergent: Too much can lead to buildup. Always follow the manufacturer’s guidelines.
- Prefer Liquid Detergents sparingly: Powder detergents often leave less residue than liquids and pods, which can build up over time.
- Clean the Machine, Not Just Your Clothes: Schedule a deep clean of your washer (inside and out) at least every one to three months.
- Wipe Away Moisture: After a wash, wipe down the drum, door, and seals with a clean, dry cloth.
- Don’t Let Laundry Sit: Remove clothes promptly after the cycle ends to prevent mustiness.
- Keep the Machine Ventilated: Propping the door and dispenser drawer open stops the internal environment from becoming hospitable to mold.
- Check the Drain Hose: Make sure the drain hose isn’t kinked or blocked, which can cause water to sit and stagnate, producing odors.
Benefits of a Clean Washing Machine
Regular washer care pays off in several ways:
- Fresher Laundry: No more musty, sour, or “wet dog” odors transferring to your clothing.
- Improved Lifespan: Keeping your machine in good shape protects its components, saving on repair costs.
- Better Efficiency: A clean machine washes clothes more thoroughly and rinses soap out more effectively.
- Energy Savings: Your washer will use energy more efficiently when it’s not fighting through layers of grime.
Common Challenges (And How to Solve Them)
1. Persistent Odors Won’t Leave
If smells linger after you’ve cleaned the drum and seals, try repeating the process with a washing machine cleaning tablet or a commercial cleaner. Sometimes, multiple cycles are necessary to break through years of buildup.
2. Moldy or Musty Seals
If the rubber gasket is blackened with mold, scrub with a paste of baking soda and water, or use a small amount of bleach diluted in water. Always wear gloves and ventilate the area.
3. Smelly Top-Loaders
Top-loaders can stink, too! Pay special attention to the area under the gasket (if there is one), the lid, and the agitator.
4. Odor Returns Quickly
Recheck washing habits—are you closing the door after every wash, or using lots of fabric softener? Small changes in daily use can have a big effect.
Routine Cleaning Checklist
Make this your monthly maintenance routine:
- Run a hot empty wash with baking soda/vinegar or a commercial cleaner.
- Clean detergent dispenser, drawer, and filter.
- Inspect and wipe the gasket/seals and drum.
- Check and clean the drain pump filter, if easily accessible.
- Dry all parts and air out the machine.
Frequently Asked Questions (FAQs)
1. Why does my washing machine smell bad even though I use it regularly?
A washing machine can smell even with regular use due to lingering moisture, leftover detergent, lint, or fabric softener residues. These provide an ideal environment for bacteria and mold, especially if the machine isn’t allowed to dry out between washes.
2. How often should I deep clean my washing machine?
It’s best to deep clean your washing machine once a month. If you do heavy or frequent loads, or use a lot of cold water washes, you might need more regular cleanings to keep odors under control.
3. Can I use bleach to clean my washing machine?
Yes, bleach can be used to disinfect and clean your washer. For a deep clean, pour about 1/2 cup of bleach into the detergent dispenser and run a hot cycle with no laundry inside. Always ventilate the room and avoid mixing bleach with vinegar or other cleaners.
4. What’s better for cleaning: vinegar or commercial washing machine cleaners?
Both options work well. Vinegar is a natural, budget-friendly choice that helps dissolve grease, grime, and odors. Commercial cleaners are specially formulated to remove tough deposits. You can alternate between the two or pick the one that suits your needs and preferences.
5. What should I do if my clothes still smell after washing?
First, check if your machine is clean—odors can transfer from the drum or seals to your laundry. Avoid overloading the machine and using too much detergent. If cleanings don’t help, try changing your detergent, and ensure you’re drying clothes properly after washing.
In Conclusion
Fixing a smelly washing machine is easier than you might think. Most bad odors are caused by trapped moisture and residue, but regular cleaning, good washing habits, and a bit of attention can keep your machine (and your laundry) smelling fresh. Remember, your washing machine works hard for you—show it some love with periodic cleaning and maintenance, and you’ll enjoy fresh, clean laundry every time.
Happy cleaning!
