Washing Machine Smells Bad? Here’s Why and How to Fix It!

A foul smell emanating from your washing machine is more than just unpleasant, it can impact the quality of your laundry. While many homeowners encounter this issue, understanding the cause and how to address it can restore your washing machine’s performance and keep your clothes smelling fresh.

In this article, we’ll explore the causes behind washing machine smells bad, practical steps on how to clean a washing machine that smells bad, and expert tips to eliminate persistent smells.

Key Takeaways

• Mold and mildew thrive in damp washing machines, leading to bad smells like a musty odor.
• Bacteria buildup in warm environments is another significant cause of odors.
• Soap scum and detergent residue can trap dirt, leading to unpleasant smells.
• Standing water and clogged filters can cause water to stagnate, creating an odor.
• Regular cleaning and maintenance can prevent most of these issues.

Causes of Bad Smells in Washing Machines

Understanding the root causes of washing machines that smell bad is essential for effective maintenance. If left unchecked, these odors can not only affect the quality of your laundry but also shorten the lifespan of your washing machine. Identifying and addressing the source of the smell early can help keep your machine running smoothly and your laundry fresh.

Mold and Mildew Growth

Moisture is a prime factor in mold and mildew growth. When your washing machine isn’t dried properly, these microorganisms thrive, particularly in warm, damp areas like the door seal, rubber gasket, and inside the drum. Mold and mildew release musty odors that get absorbed by your clothes, leaving them smelling stale even after a wash.

Bacteria Buildup

Bacteria love warm, humid environments,  and unfortunately, that’s exactly what washing machines provide. If your washing machine is frequently left damp, bacteria can multiply rapidly, leading to unpleasant smells that seep into your laundry.

Soap Scum and Detergent Residue

Excess detergent or fabric softener can leave behind soap scum and residue, especially in high-efficiency washing machines. These residues trap dirt, oil, and other particles, causing unpleasant smells to develop over time.

Tip: Use the correct amount of detergent for each load and clean the detergent tray regularly to avoid buildup.

Standing Water

If your washing machine isn’t draining properly, standing water can accumulate in the drum or hose, producing a foul smell. This stagnant water provides a perfect breeding ground for bacteria and mold.

Clogged or Dirty Filters

Washing machines have filters that catch dirt, lint, and debris from clothes. If these filters become clogged or dirty, they can trap moisture and grime, causing bad odors to build up.

Tip: Clean the filters regularly to ensure proper water drainage and to avoid buildup of unpleasant smells.

Signs Your Washing Machine Smells Bad

Recognizing the signs early can help you address the problem before it worsens. Here are some key indicators that your washing machine smells bad and needs attention:

• Foul odor when opening the door.
• Clothes coming out with a musty or sour smell.
• Visible mold or mildew around the door seal or drum.
• Persistent damp smell in your laundry room, even after washing.

If you notice any of these signs, it’s time to take action.

How to Prevent Bad Smells in Washing Machines

Preventing odors in your washing machine is easier than dealing with them after they develop. By incorporating regular cleaning habits and proper usage, you can keep your machine smelling fresh and functioning efficiently. Simple steps like leaving the door open after each wash and using the right detergent can go a long way in preventing unpleasant smells from taking hold. If you’re unsure about the best practices or need professional help, consider reaching out to Smart Appliance Services for expert advice and assistance.

1. Proper Loading

Avoid overloading the washing machine to ensure that water and detergent can circulate freely. Overloading leads to poor washing and trapped moisture, which encourages bacterial growth.

2. Use the Right Detergent

Use high-efficiency (HE) detergents if you have an HE washing machine. These detergents are formulated to create fewer suds and leave less residue, reducing the chances of soap scum buildup.

3. Leave the Door Open

After each load, leave the washing machine door open to allow air circulation and prevent moisture buildup inside. This simple step can go a long way in preventing mold and mildew.

4. Regular Cleaning

Make it a habit to clean your washing machine regularly. Run a hot wash cycle with vinegar to help clean the drum and kill bacteria. Don’t forget to clean the detergent tray and rubber seals.

5. Use a Washing Machine Cleaner

Occasionally, use a commercial washing machine cleaner to deep-clean the machine and keep it fresh.

How to Fix a Smelly Washing Machine

To address a washing machine that smells bad, start by cleaning the drum and door seal. Wipe the rubber door seal with a vinegar solution to remove any mold or mildew buildup, which can contribute to a musty odor. Then, run a hot water cycle with baking soda to clean the drum and eliminate lingering odors, helping to freshen up the machine.

Next, remove the detergent tray and clean it with warm water to remove any soap residue or mildew. This step is essential for preventing soap scum and detergent residue, which can lead to unpleasant smells. Afterward, inspect the drain and filter for blockages, ensuring both are clean and clear to promote proper water drainage and avoid any standing water, which can cause bad odors.

Running a cleaning cycle using vinegar or a commercial washing machine cleaner can help remove bacteria and soap buildup, restoring freshness. Finally, if your washing machine isn’t draining properly, check the hoses for clogs and clean them out to ensure proper drainage and avoid stagnant water, which contributes to foul smells.

When to Call a Professional

Washing machine repair is sometimes necessary when the odor persists despite your best efforts at cleaning and maintenance. If the washing machine smells bad even after thorough cleaning, it could indicate a deeper issue that requires professional attention. If you notice persistent smells, water leaks, or drainage problems that aren’t resolved by standard maintenance, it’s a sign that your washing machine may have an underlying mechanical or plumbing issue.

Also, if your machine isn’t draining or spinning properly, or if you’re unable to resolve the smell through normal cleaning cycles, it may be time to call in a technician. A professional will be able to diagnose and fix more complex problems that could be causing the unpleasant odors, ensuring your washing machine runs smoothly again.

Final Thoughts 

Bad smells from your washing machine are usually a sign of poor maintenance or underlying issues. By understanding the causes and taking proactive steps to clean and care for your washing machine, you can prevent unpleasant odors from affecting your laundry. Regular cleaning and proper usage will ensure that your machine stays fresh and continues to work efficiently for years.
