Why does My Washing Machine Smell Like Rotten Eggs? Common Causes

Washing machines are a staple in our homes, ensuring our clothes come out fresh and clean. But when your reliable machine starts smelling like eggs, it’s time to figure out why. Understanding these factors is the first step in restoring a pleasant laundry experience.

Mold or Mildew Buildup:

Cause: Mold and mildew often grow in wet spots, especially in the rubber part around the door. These things like the dark, moist inside of the washing machine make it smell bad.

Solution: To combat mold or mildew buildup, adopt a proactive cleaning routine. Clean the rubber part and soap drawer often with water, vinegar, or a safe cleaner. Keep the door open when not washing to help it dry and stop mold.

Dirty Drum or Agitator:

  • Cause: Accumulated dirt, soap scum, and fabric softener residues in the drum or on the agitator can result in unpleasant odors. These residues compromise the cleanliness of your clothes and contribute to the overall malodor.

  • Solution: Combatting a dirty drum or agitator involves a specialized cleaning cycle. Run a hot water cycle with white vinegar or a special cleaner to clean your washing machine. Wipe the drum and agitator regularly with a wet cloth to keep them clean for better washing..

Clogged Drain:

  • Cause: A clogged drain can trap water, leading to foul smells. Debris, lint, and soap scum can accumulate over time, obstructing the smooth flow of water and causing stagnation.

  • Solution: To address a clogged drain, routinely check and clean the drain filter. Run hot water with vinegar or baking soda to break down deposits and ensure the water drains well. This proactive approach eliminates odors and prevents potential water damage to the machine.

Sewer Gas Backflow:

  • Cause: If your washing machine is connected to a drain pipe sewer gas leak, unpleasant smells permeate your laundry area.

  • Solution: Ensure the drain hose goes up slightly to stop water from flowing back. Check that it’s not in water and consider using a drain vent to keep bad smells out of your washing machine.

Hard Water Issues:

  • Cause: Hard water can make your washing machine smell bad and work less well by leaving deposits.

  • Solution: Address challenging water issues using a water softener with your detergent. Sometimes, clean your washing machine by running a descaling cycle with citric acid or a special cleaner. This helps stop hard water deposits and keeps your appliance working well.

Bacterial Growth:

  • Cause: Germs like warm, wet places, and washing machines can get filled with them.

  • Solution: Stop bacteria by often running hot water cycles with bleach or hydrogen peroxide. This not only kills germs but also stops them from coming back. Let air in to help things dry out, making it harder for bacteria to grow.

Using Too Much Detergent:

  • Cause: Too much detergent can leave behind sewage or rotten eggs smell coming from your washing machine. This can make your clothes and the machine not smell good.

  • Solution: Adhere to the manufacturer’s recommendations for detergent usage; change the amount based on how big the load is and how hard the water is. If you have a high-efficiency machine, use less detergent for the best results.

Suppose the issue persists despite implementing these solutions. It’s a good idea to check the washing machine manual or ask the maker for help that fits your machine. Addressing the problem systematically ensures a cleaner, more efficient, and odor-free washing machine.

Impact on Clothes and Machine Performance

A stinky washing machine doesn’t just smell bad; it can also make your clothes dirty and the machine not work well.

Stains on Clothes

When your washing machine smells bad, it can stain your clothes. The leftover soap, mildew, and mold can stick to your laundry and make ugly marks. These stains make your clothes dirty and can be hard to remove.

Reduced Efficiency

A smelly washing machine is often an inefficient one. When soap, mold, and mildew build-up, your washing machine might not clean clothes well. With time, your washes might not work either, and you might need to try harder to clean your clothes.

Potential Damage to the Washing Machine

If you ignore a foul smell from your front-load washer, it could harm the machine. Mold and mildew in wet, dark spots can hurt the inside parts and make the device not work right. If you wait too long, it might need expensive fixes or a new machine.

Knowing how it affects clothes and the machine shows it’s crucial to fix a smelly washing machine fast. Next, we’ll look at ways to stop it from smelling and natural ways to eliminate the odor.

Preventive Measures

Make sure your washing machine always smells nice. Fixing the smell is important, but it’s also good to do things to stop the problem from happening. Here are some practical steps to ensure your washing machine stays odor-free.

Regular Cleaning Routines

Establishing a routine for cleaning your washing machine is essential for preventing unpleasant odors. Begin by cleaning the detergent drawer and any removable parts. Wipe down the rubber seal and drum to remove residual detergent or moisture. Regular cleaning helps eliminate mold, mildew, and detergent residue buildup.

Use the Right Detergent and Amount

The type and quantity of detergent you use are crucial factors preventing washing machine odors. Opt for high-efficiency (HE) detergents that produce fewer suds, minimizing residue. Also, use the amount of detergent the maker and the washing machine book say to avoid too much buildup.

Proper Ventilation

Ensuring proper ventilation around your washing machine can contribute significantly to odor prevention. Leave the washing machine door open between cycles to allow air circulation and reduce the likelihood of mold and mildew growth. If your laundry room has adequate ventilation, it creates an inhospitable environment for odor-causing bacteria.

Checking and Cleaning the Filter

Many washing machines have filters that trap lint, hair, and other debris. Check and clean the filter often to stop bad smells. Look in your machine’s manual to find and care for the filter because different washers have different filters.

Doing these things when you do your laundry can help avoid a smelly washing machine.

Natural Remedies to Clean Smelly Washing Machines

Dealing with a smelly washing machine doesn’t always require harsh chemicals. You can employ several natural and eco-friendly remedies to eliminate unpleasant odors and restore a fresh scent to your laundry haven.

Vinegar and Baking Soda Cleaning

Vinegar and baking soda are the most influential and widely recommended natural remedies. Start by running an empty hot water cycle with 1 or 2 cups of white vinegar. This helps break down detergent residue and disinfect the interior. Follow up with a process containing a cup of baking soda, targeting any remaining odors and leaving your washing machine smelling fresh.

Lemon Juice as a Natural Disinfectant

Lemon juice kills germs and smells good. Mix lemon juice and water, and use a cloth or sponge to wipe the inside of the washing machine, significantly where mold and mildew grow. This not only removes existing odors but also acts as a preventive measure.

Sun Drying the Washing Machine

Sunlight is a natural disinfectant and deodorizer. After cleaning with vinegar or lemon juice, open the washing machine door and let it air dry in the sunlight. Letting sunlight in and opening windows helps eliminate smells and stops mold and germs from growing.

These natural ways work for fixing washing machine smells and are better for the environment.

Technical Troubleshooting

Conducting a thorough inspection is essential for those who prefer a more technical approach. Check for leaks, inspect the drain hose for blockages, and verify that the washing machine settings are optimal. Addressing these technical aspects can contribute significantly to odor eradication.

Professional Help

It makes sense to get professional help in some situations. Knowing when to ask a technician for help and understanding maintenance services can stop problems and keep your washing machine safe.


In summary, a stinky washing machine is more than just annoying but can cause problems. If you know what causes it and do things to stop it, your laundry area can stay fresh and work well. Cleaning often, using natural fixes, and solving technical issues all help eliminate bad smells.
