Why Does My Laundry Machine Smell and What to Do About It

The laundry machine smell - it's a common problem that can be a real nuisance. Mold and mildew are often the culprits behind this stinky issue.

Your laundry machine can develop a musty smell due to excess moisture and poor ventilation. This is especially true if the machine is located in a humid area or if the drain pump filter isn't cleaned regularly.

To get rid of the smell, try running a cleaning cycle with a laundry machine cleaner or a cup of white vinegar. This will help loosen and remove any built-up debris and odors.

Regular cleaning and maintenance can go a long way in preventing the growth of mold and mildew in your laundry machine.

Your laundry machine might smell like a mix of mold and mildew, a sour or sewage-like odor, or even a strong, chemical-like smell. This is usually due to a buildup of bacteria, mold, or mildew in the machine.

Mold and mildew growth thrive in the moist environment of a washer, especially when the washer door is left closed between uses. This can cause a musty, damp scent.

Bacteria can grow from residual detergent, fabric softener, or stagnant water left in the machine. This can lead to a sour or sewage-like odor.

Detergent and fabric softener residue can also contribute to a strong, chemical-like smell. Overuse or misuse of laundry additives can leave behind a residue that traps bacteria.

Drainage problems can cause a smelly washer, too. If the water isn't draining completely or properly, it can lead to stagnant water and bacterial growth.

Plumbing issues, like backflow problems or trapped gases, can also cause a rotten egg or sewage smell. This is often due to hydrogen sulfide gas, a byproduct of bacterial buildup.

Here are some common causes of a smelly laundry machine:

Cleaning your washing machine regularly is key to preventing musty smells. To do this, you should deep clean your washer weekly or bi-weekly, depending on how often you use it.

You can start by removing and scrubbing the detachable dispensers, which can accumulate old detergent, softener, and water, creating an ideal environment for bacteria and mold to thrive. Soak the dispensers in a mix of hot water and vinegar or bleach, then scrub them with a cleaning brush and rinse thoroughly.

To prevent smells from returning, make sure to leave the washer door open between uses, allowing air circulation and drying out the interior. You should also run hot water cycles periodically to sanitize the machine and break down oils or residues that cold water can't.

If you're looking to deep clean your top-load washer using bleach, you'll want to start by emptying the washer bin and soap dispensers of clothes and laundry detergent or fabric softeners.

To select the right washing cycle, choose the one with the largest load, longest cycle time, and hottest water. If your washer has a "self-clean" cycle, go ahead and select that.

Add 4 cups of bleach to the washer once it's full, but before it starts to agitate. Then, close the lid and allow the machine to agitate with the bleach and water for one minute.

Pause the cycle for one hour to allow the bleach and water to soak in your washer. Some models don't allow you to pause the cycle, so let the washer finish its cycle and then follow the rest of the cleaning steps.

After one hour of soaking, close the lid and let the machine finish the cycle. Remember, don't mix bleach and vinegar as this creates lethal chlorine gas.

First, take out and clean the detergent drawer, which is often a breeding ground for mildew and bacteria.

Removing and cleaning the detergent drawer is a simple process that can make a big difference in eliminating the smell.

Run an empty hot cycle using a commercial washer cleaner or add 2 cups of white vinegar to the detergent dispenser and sprinkle ½ cup of baking soda to help neutralize any lingering odors.

Top-loaders are more prone to mold and mildew growth due to their design, which can trap moisture.

High-efficiency (HE) machines use less water and detergent, but can be more susceptible to odors if not properly maintained.

Front-loaders are more likely to develop musty smells due to their tendency to retain water in the gasket and drum.

Regular cleaning of the gasket and detergent dispenser can help prevent odors in front-loaders.

To reduce odors in top-loaders, run a cleaning cycle with a laundry cleaner or a cup of white vinegar every 1-2 months.

HE machines require less detergent, but using too little can lead to residue buildup and odors.

Front-loaders often require more frequent cleaning due to their design, which can trap debris and moisture.
