This is a common problem that can be caused by a variety of factors. In this blog post, we’ll describe the most likely causes of this smell and how to fix them. We’ll also provide some tips on how to prevent your washing machine from smelling bad in the future.

Why Does My Washing Machine Smell Like Rotten Eggs?

If you’ve ever noticed your washing machine giving off a foul smell, it’s probably because of bacteria build-up. This can happen even if you clean your machine regularly. The humid, dark environment inside your washing machine is the perfect breeding ground for bacteria. Over time, these bacteria can produce sulfuric compounds that stink like rotten eggs.

If you notice that your washing machine has started to emit a foul odor, there are a few potential causes that you should be aware of. The most likely causes of a smelly washing machine are built-up dirt, mold, or mildew.

Built-Up Dirt

One of the most common causes of a smelly washing machine is built-up dirt. Over time, laundry detergent and fabric softener can leave behind a residue on your machine’s interior surfaces. This residue can then attract dirt and other debris, leading to a build-up that can start to emit an unpleasant odor. To prevent this from happening, be sure to clean your washing machine’s interior surfaces on a regular basis.

Mold Or Mildew

Another potential cause of a smelly washing machine is mold or mildew. These growths can occur if there’s excess moisture present in your machine. When this happens, it’s important to take action right away to clean the affected areas and eliminate the source of the moisture. Otherwise, the problem will only continue to get worse and the bad smell will become more difficult to get rid of.

Does The Style of Washer Affect Potential Smells?

Top or front-loading washing machines can both experience this problem. However, due to the way they operate, a front-load washing machine is more likely to develop washer smells than a top-load washer,

Front-loader washing machines are more prone to the smell of rotten eggs because they don’t have a built-in agitator. The agitator helps to circulate the water and keeps the clothes from sitting in one spot and getting stinky. Front-loaders also don’t have as much room for air circulation, which can lead to smells getting trapped inside the machine.

To prevent your front-loading washing machine from smelling like rotten eggs, make sure to clean it regularly with a vinegar solution. If you notice that your clothes are starting to smell bad, wash them on a hotter cycle or add a cup of vinegar to the wash.

Does The Water Quality Affect Potential Smells?

It’s no secret that water quality can affect the way things smell. After all, if water is contaminated with certain bacteria or other pollutants, it can produce some pretty unpleasant smells. But what about the potential for smells of rotten eggs? Can water quality actually affect that?

As it turns out, the answer is yes. Water quality can definitely affect the way things smell – and that includes the potential for smells of rotten eggs. This is because water that is high in sulfur content can lead to the production of hydrogen sulfide gas. And when that gas is present, it can give off a distinct odor rotten egg odor.

So why does water quality affect the potential for hydrogen sulfide gas production? Well, it all has to do with the way that sulfur-containing compounds break down. When these compounds are present in water, they can undergo a process called anaerobic decomposition. This process doesn’t require oxygen, and it can produce hydrogen sulfide gas as a byproduct.

The good news is that there are ways to treat water to remove sulfur-containing compounds. This can help to reduce the potential for hydrogen sulfide gas production – and the associated smells of rotten eggs. If you’re concerned about the quality of your water, be sure to talk to a professional about the best way to treat it.

What To Do If Your Washing Machine Smells Like Rotten Eggs

Smelly Washing MachineIf you’re noticing an unpleasant odor coming from your washing machine, chances are it’s due to one of the above-mentioned causes. All you have to do now is figure out where the stench is coming from and then take the appropriate measures.

Identify The Source Of The Smell

Is It The Drain?

The first thing you’ll want to do is identify the source of the smell. If it’s coming from the washing machine drain, then there’s likely some build-up of organic matter causing the problem. This can often happen if you have a septic tank or are on a well water system.

Is It The Drain Line?

If the rotten eggs smell is coming from the drain line, the reason is likely due to a build-up of bacteria. This can happen if the line is not properly cleaned on a regular basis. It can also be caused by a blockage in the line. Either way, it’s important to take action to clean the line and get rid of the bacteria.

Is It The Washer Itself?

If the smell is coming from the washing machine itself, then it could be due to a build-up of detergent or fabric softener. Another possibility is that something has died inside the machine, such as a mouse or rat.

Take Action

Once you’ve identified the source of the smell, you can start taking steps to fix the problem.

  • If the washing machine drain smells, you can try using a plunger or a plumber’s snake to clear any blockages. You may also need to use a cleaner designed specifically for drains, such as Drano.
  • If the smell is coming from the drain line, it will need to be cleaned. This can be done by using a plunger or a drain snake. If the smell persists, it may be necessary to replace the washing machine’s drainage hose.
  • If the smell is coming from the washing machine, you’ll need to clean it out thoroughly. Start by running an empty cycle with hot water and vinegar. This will help to remove any build-up of detergent or fabric softener. The vinegar will help to neutralize the sulfur compounds and should get rid of the smell.
  • If the vinegar doesn’t work, you can try running a cycle with a half-cup of baking soda. Baking soda is another effective neutralizer of sulfur compounds.
  • If there’s still a lingering smell, you can try cleaning the machine with bleach. Be sure to follow the manufacturer’s instructions carefully when using bleach, as too much can damage your machine. Also, wear a mask and rubber gloves and handle the bleach very carefully.

Once you’ve taken care of the source of the smell, be sure to keep your washing machine clean and free of any build-up. This will help to prevent the problem from happening again in the future.

Preventing Your Washing Machine From Smelling Like Rotten Eggs In The Future

Rotten egg smells are typically caused by a build-up of sulfur in the washer. Sulfur is found in many things, including detergents, fabric softeners, and even dirty laundry. When sulfur builds up in your washer, it can create an unpleasant smell.

There are a few things you can do that will help prevent sulfur build-up and reduce the potential for smells:

Detergent Choice

Smelly Washing MachineThe wrong detergent or too much detergent can contribute to the problem.

  • If you have a front-load washer, use a high-quality detergent that is specifically designed for that style of the washing machine.
  • You could also use a detergent that contains bleach or other disinfectants. These will help to kill any bacteria that are present in your machine.
  • Use less detergent than what is recommended on the package.
  • Use hot water for appropriate loads. Hot water kills bacteria more effectively than cold water.
  • Add one cup of distilled white vinegar to each load of laundry. Vinegar helps to break down sulfur and other build-ups in your washer.

After Each Load

Adequate ventilation reduces the level of moisture in the air and prevents the growth of mold and mildew.

  • Leave the washer door open after each load to allow the inside to dry out completely.
  • You should also ventilate your laundry room to prevent smells from building up.
  • If possible, wipe down the inside of the washer with a clean, dry cloth after each use. This will help to remove any residual moisture and detergent build-up.

Cleaning Process

Washers need to be cleaned on a regular basis to prevent the build-up of dirt, detergent, and other materials. At least once a month:

  • Run an empty load with hot water and a cup of white vinegar. This will help to clean the machine and remove any build-up that has occurred.
  • Check and clean the washer filter regularly.
  • Check and clean the drain line regularly.
  • Wipe down the inside of the washing machine with a damp cloth using white vinegar or a mild detergent with water.
  • Also, be sure to clean the washing machine door seal and detergent dispenser on your machine regularly. These are two of the most common places for bacteria to build up.

Following these simple tips, you can keep your washing machine smelling fresh and clean.

How To Clean The Dispensers

Once every three months, you should also clean the washing machine’s dispensers. These can become clogged with detergent and fabric softener build-up over time.

  • To clean the dispensers, simply remove them and soak them in hot water for a few minutes. Then, use a brush to scrub away any build-up that is present.
  • Once you have finished cleaning the dispensers, replace them and run a short cycle with hot water and vinegar to flush out the system.

How To Clean A Dirty Washer Filter

If your washing machine’s filter becomes clogged, it can cause a rotten egg smell. And if it becomes clogged, it can cause the machine to work less efficiently and may even lead to more serious problems. Fortunately, cleaning a dirty washer filter is a relatively easy task that you can do yourself.

Here’s how to clean a dirty washer filter:

1. Unplug the washing machine from the power outlet.
2. Locate the filter. This is usually located near the bottom of the machine, behind a small door or panel.
3. Remove the filter and rinse it thoroughly under running water. If there is a lot of build-up on the filter, you may need to soak it in hot water for a few minutes before rinsing.
4. Replace the filter and close the door or panel.
5. Plug the washing machine back in and run it on a short cycle to make sure everything is working properly.

If you notice that your washing machine’s filter is getting dirty more quickly than usual, there may be something else going on that needs to be addressed. For example, if you have hard water, the minerals in the water can cause buildup on the filter more quickly. In this case, you may need to install a water softener to help prevent the problem from occurring again in the future.

What To Do If The Smell Continues To Persist

Smelly Washing MachineIf you are still experiencing unpleasant smells after taking these steps, it’s possible that the water quality is to blame. Hard water can cause sulfur build-up, so if you have hard water, you may need to install a water softener. Alternatively, you could try using bottled water for your laundry.

If you’ve tried all of these things and you’re still having trouble, it’s time to call a professional. A qualified technician can inspect your washer and determine the cause of the smells. They may need to clean your washer or make some repairs. Either way, they will be able to get rid of the rotten egg smell for good.


That awful smell is a common problem, but with these hints, you can have a fresh-smelling laundry room again!
