Why does my washing machine smell?


Kenmore washing machine

How long has it been since you cleaned your machine? Maybe you had no idea that it should be cleaned once in a while. It’s time to make a room in your schedule for your clothes-washing device maintenance. 

Your machine needs a cleansing procedure once in a while because of bacteria. If you often do the laundry in low temperatures, you risk getting a smelly machine. Bacteria are everywhere, and they multiply faster in cold conditions. 

You should do your laundry in hot temperatures, not just so you can avoid bad odors. Your clothes need to be disinfected and decently cleansed. The clothes mold if there are some bacteria left on them after washing. You can achieve a good result with hot water. That’s why it’s more reasonable to stop saving your money at the expense of quality. You never know when excessive economizing will cost you more money. 

When it comes to the cleaning part, bacteria are not the only issue. Sometimes, washing your clothes can tear inside the drum and leave small pieces there. After a time, they’ll rot and smell. Insects can also enter the system and contribute to the sewer odor. That’s why you should carefully clean your machine with the help of a manual. It’ll tell you what part to remove and how to put it back.

You may not believe it, but using too much detergent for your laundry can cause a sewer stench in the washing machine. When the amount of detergent is disproportional to the amount of water, it stays in the drum after the washing is done. Detergent is a perfect agent for bacteria to develop and multiply. That is why the more, the better does not work. Choose the right amount of detergent, and you’ll have a better chance of not facing sewer smell in the future. 

One of the reasons your washer smells is unclean water. Filthy water can get into your machine if it is connected to the kitchen sink with the same drain hose. When you empty it, the smelly water may come straight into your clothes washing device and produce a smell of sulfur. To prevent that, make sure your drain hose is connected correctly. 

Sewage smells can occur when you have a clogged p-trap, drain, or vent pipe. The first one you can clean on your own by pouring water through it. For the second one, it’s better to call a plumber with a sewer, especially for such occasions. A professional plumber will also do good with unclogging vent pipes. However, you can use improvised materials to pull out anything that has gotten stuck there. If that doesn’t work, use a professional assistant. 

If you notice that your washing machine smells like sewage, there are two things you can do about it. Find out what causes it and get rid of it on your own. The other resolution is to call the plumber and throw any worries off your shoulders.

Rotten eggs

The smell of rotten eggs is in no way something you want to sense in your laundry room. The same annoying bacteria often cause it as the smell of sewage. During washing, your clothes tend to leave hair, small threads, or tiny fibers inside of the drum. Without proper cleaning, all those things will rot and develop a smell inside of the machine. 

Often, bacteria multiply inside detergent trays. If you don’t clean it, the detergent will accumulate and become a slimy substance. After a time, it develops the smell of rotten eggs in the washer. Ideally, you should clean your washer once a month, so this unfortunate thing will have no chance of happening. 

To avoid the smell of rotten eggs coming out of your detergent tray, consider cleaning it and changing your regular detergent. Some of the products tend to stick to the surface better than others. If you have a high-efficiency washing machine, buy a special detergent that is suitable for it. That will give no chance to bacteria unless you forget about cleaning at all. 

One of the reasons for the rotten egg smell is a possible gas leak. When it comes to gas, manufacturers often lubricate the parts of the machine with a special substance. If it comes into contact with the gas, you’ll smell sulfur in your bathroom. You should immediately call for professional assistance when you suspect a gas leak.

How do I get rid of the smell?

Use a vinegar mixture to clean your drum.
One of the cheapest methods to clean your appliances is by using vinegar. All you need to do is mix it with water and then spray it inside the drum. Make sure not to miss any elements. For better effect, you can take a cloth. Wet it with vinegar and then wipe the inner parts of the drum. Don’t forget about the rubber gasket, as it is a place where all the mold often accumulates. You can also wipe the outside parts, but be careful with the wires.

Make a vinegar mixture for a more thorough cleaning.
After you do the swiping, mix one cup of vinegar with five tablespoons of baking soda and pour it into the detergent tray.

Run a hot cycle
Turn on your washing machine to the hottest cycle it has. Some sites suggest substituting vinegar with bleach. It is logical to use it against bad smells. In reality, bleach worsens the state of the drum. If you don’t trust the idea of home-made methods, buy a special cleaner for your washing machine. It’ll do the job even more effective than traditional methods.

Why did a smell develop?

Different types of smells can come out of your machine. Each one points out a particular issue within this appliance. The smell of sewage often comes from the sewer. When you sense this kind of odor, it’s important to tackle it immediately because the gases from down there are toxic. However, there can be different reasons for sewage odor. If you clean your washer and it stays, there will be no doubt that the sewer causes you trouble.

If you smell rotten eggs and it doesn’t come from your kitchen, it’s probably your washing machine gone bad. This type of smell is related to all the bacteria that accumulate in the drum. It happens naturally with all appliances that come into contact with moisture. The good news is that you can easily get rid of that type of smell by following simple steps. Do not cease reading to find out more about this common problem. 

When it comes to moisture, the other typical thing that it causes is mold. If you smell mildew coming from your washer, it’s time to clean it. Appliances that regularly face water will develop mold without cleaning.

The gasket is the rubber ring around the drum. It is particularly vulnerable to moisture. It has a bent shape, which means that some of your tiny clothes can get stuck there. If you feel a damp odor coming out of the drum, inspect it closely for lost pieces of clothes. The next step is to wash your appliance. 

A burning smell is the opposite stench that can come out of a washer. That one signifies mechanical damage to the internal parts. When your bathroom stinks as if something is burning in it, it’s time to call for mechanical support from a professional technician. 

It can have a burning smell because of a malfunction of the motor, drive belt, drive couplings, or other electrical elements. The issue can also be within a plug or socket. If you notice a burning stench, immediately unplug the device. Without doing so, there is a great risk of fire. After unplugging your machine, call the technician. 

Of all the possible odors that can come from your washer, the smell of rotten eggs and sewer stench are the most common. So what are the reasons why a washing machine smells like rotten eggs and sewage? The following information will answer that question and tell you what to do in that case.

Are you ready to get a new one?

Sometimes cleaning is not enough to banish the odor. Like any other household appliance, washing machines break down without any chance for repair. If there are still parts you can mend, it usually costs more than the new one. That’s why it’s reasonable to consider buying new, highly-efficient appliances.

Why trust us and how we picked?

It certainly isn’t easy to get rid of these pesky smells, but since they’re pretty common it’s easy to experiment and research with the solutions. That’s exactly what we did! Cleaners in the market in each budget category and brand were both tried and tested and we have provided you the top 3 right here. The best washers have also been listed after much research of customer reviews and trying out each product personally.

How much do they cost?

You can be done with cleaners like Active and Dr. Beckman within a range of just $8-16.

Washers and dryers are another ball game. Kenmore models like the one listed above is between $499- $620 depending on where you get it from. While LG models will be almost double the cost at $1100-1200. However, single unit Washtower design with dryer included will cost you around $2000 and upwards.

Factors to consider

Here are a few things to keep in mind while shopping for new washers:


How many members are in your family? Is it just you and your partner? Are there kids in the house and especially babies who frequently need changes and hence the laundry piles up quick. This will impact the size of your washer.


Stackable washer and dryers enable space saving that is much needed in cramped apartments. However, large spaces can make do with separate washer and dryers. Maybe you like to change things up a bit or are prone to moving around a lot – then portable washing machines are for you.

Preference of top/front load

There might not seem to be a difference but there are some. A top loading machine is easy on the back while the front load is not so much. A top loading machine doesn’t require a direct water connection while a front loading one does. However, a top loading washer can prove dangerous if the house doesn’t have earthed wiring. It’s not possible to load the front loading machine midway whereas a top loading machine provides this flexibility.
