How to Remove Washing Machine Smells: 7 Methods

Try these seven methods for removing bad washing machine smells. 

If your clothes are consistently coming out of the washing machine smelling foul, then it’s probably a problem with the machine over anything else.

In our home, we love keeping our appliances clean. It’s not a hard job, and it makes sure that the clothes are always as clean as possible.

We’ve researched a few different reasons why your washing machine could be smelling and how to get rid of these smells. So next time you go to a load of laundry, the only thing you will be smelling is the lovely scent of your chosen detergent.

Key Takeaways

  • Washing machine smells can be caused by bacteria, mildew, mold, lint, soap, or gas leaks.
  • To eliminate odors, clean the machine with a vinegar and water solution, clean pipes, and clear the detergent dispenser.
  • Deep clean the drum once a month using distilled white vinegar or bleach on the highest water temperature available.
  • Prevent future smells by leaving the door open to dry, changing detergents, and cleaning the filter regularly.

Why Your Washing Machine Smells

Before you get rid of the smell, you need to locate where it’s coming from and what’s causing it. Here are a few main reasons why washing machines smell bad.

Washing Machine Smells Like Sewage

If your washing machine smells like sewage, it’s important to tackle this right away as the sewer gases are potentially hazardous.

It could simply be that the machine smells like sewage, but isn’t necessarily caused by sewage. However, if it still smells bad after being cleaned, then it is most likely coming from the sewer.

The p-trap may be trapping sewer gases from underground sewer pipes which are now coming into your washing machine.

Rotten Egg Smell

A rotten egg smell is either caused by bacteria growth due to dirt, mildew, mold, lint, or soap left in the machine. Or it’s caused by a gas leak, which comes up as an eggy or sulfur-like smell.

Mildew/Damp Smell

Mildew and damp smells are caused by a heat and water buildup in the machine that’s never aired or cleaned out. If water sits in the machine, in the gaskets, or in other crevices, it can lead to these nasty smells. There may even be a wet sock or something stuck in the rubber gasket which is leading to the terrible odor.

Washing Machine Smells Worse After Cleaning

But what if you’ve cleaned your machine, and it isn’t any better? Or maybe it even smells worse?

This could be a sign that cleaning it actually worked. The cleaning solution you used, or even the hot water, may have broken up some hidden gunk that didn’t get completely washed away and now it’s sitting in your machine.

Another reason could be a blockage in the standpipe.

Washing Machine Smells Like Burning

It’s hard to pinpoint a burning smell down to one thing without servicing the machine. It’s most likely down to the malfunctioning of one of the internal parts. It could be a motor, pump, drive couplings, seals, a drive belt, or other electrical parts.

It could also be that the burning smell is coming from the plug or socket, rather than the machine.

Word Of Warning

If you notice a burning smell, unplug your machine and don’t touch it. Even after a washing machine has been turned off and unplugged, it can still be dangerous for a while afterward. Contact a professional for assistance.

How to Get Rid of Washing Machine Smells

There’s nothing more annoying than a stinky washing machine ruining your laundry routine. Thankfully, there are some easy and effective fixes to getting rid of that odor once and for all.

Vinegar and Water Solution

This is the solution we use to clean our washing machine and it works a treat.

  1. Mix together a 1:1 solution of distilled white vinegar and water in a spray bottle. Add about 10 drops of your favorite essential oil if you want.
  2. Spray the entire inside of the washing machine. Don’t forget all around and inside the folds of the rubber gasket.
  3. Take a damp cloth and scrub the inside of the machine well.
  4. Do the same on the outside of the machine and the door. Avoid electrical buttons.

This can help to get rid of all sorts of bad smells, even from mildew, dampness, and sewage-like or rotten egg-type smells.

Clean Out the Pipes

Clogged or dirty pipes can lead to bad smells, especially sewage-like smells. There are a few pipes that you should work on cleaning out.

Firstly, you should try cleaning out the p-trap. Simply pour a gallon of water down this pipe which should clear it and remove the smells. If the smell remains, call a plumber.

Another pipe to clear out is the drain pipe. For this, you should call a plumber who will use a sewer machine to clear this.

Lastly, you may need to clean out the clogged vent pipe. Follow these steps:

  1. Call a professional to do this. However, if you’re trained in this kind of work, safely get yourself on the roof and shine a flashlight down the vent pipe.
  2. Pull out anything causing an obvious blockage such as a bird’s nest, leaves, or other debris.
  3. If it’s too difficult to pull out by hand, use a long-handled tool to remove it.

When In Doubt

Call a professional to deal with pipe problems, especially if it’s sewage smells you’ve found. The gases can be dangerous so it’s often best to leave it to a professional.

Clean the Detergent Dispenser

The detergent dispenser rarely dries out fully, making it the perfect place for mold and mildew to grow. Here’s how to clean it out:

  1. Remove the drawer if possible.
  2. Fill up a basin of hot soapy water and let the drawer soak in there for about an hour.
  3. Use an old toothbrush to scrub away loosened dirt and debris.
  4. Use a pipe cleaner to dig out lodged dirt inside the pipes behind where the drawer goes in the machine. This may be gross, but it will help!
  5. Dry the drawer thoroughly.
  6. Before you put it back in, use a surface cleaner or your vinegar spray from step one to clean out the crevices where the drawer goes.
  7. Replace the drawer.

After each cycle, it’s a good idea to let the detergent drawer air out. Leave it open until fully dry.

Deep Clean the Drum

This may be the most important step to removing bad odors. Deep cleaning the drum can kill bacteria, mold, mildew and just remove other nasty lingering smells.

  1. Check your manufacturer’s instructions for their advice on how to clean the drum. Some may recommend a certain cleaning solution for the machine.
  2. Pour one cup of distilled white vinegar or bleach into the detergent drawer, or directly to the drum for top-loading models.
  3. Set the machine to a long hot cycle. Use the highest water temperature available.
  4. Let the cycle run fully.
  5. Open the door and let the machine air dry.

Do this at least once a month.

It Still Smells

If your machine still smells, or smells worse, after doing this, repeat the process. You may have dislodged dirt and the machine didn’t fully rinse it away.

Change Detergents

Did you know that it could be your detergent that’s actually causing the bad smells? Who would have thought! Shouldn’t detergent be cleaning anything it comes in contact with?

Not necessarily.

Some heavy-duty detergents are hard to rinse away, especially if you use too much. It can cling to the insides of your machine and over time, this leads to a bad smell. Likewise, if you have a high-efficiency washer and aren’t using HE detergents, this can lead to bad smells.

Switch to a detergent that is HE-friendly if you have an HE washer. You may also want to consider a laundry detergent that doesn’t suds up as much. More suds often mean more scum is left behind.

You could also change the type of detergent you are using, switching to powder detergent or pods which are less likely to leave behind a film like a liquid detergent will.

Ditch The Fabric Softener

We also recommend ditching the fabric softener. This stuff clings to your clothes and your machine which can lead to bad smells. Instead, swap it out for one cup of distilled white vinegar.

Leave the Door Open

It may not be the most aesthetic choice, but it’s the best one for minimizing and preventing odors. After a cycle, remove your clothes and leave the door open so moisture can escape and the drum can fully dry.

You should also dry the inside of the door after a cycle. Just use a dish towel to remove water droplets.

As an extra measure, run a fan in the room or use a dehumidifier in extreme cases.

Clean Your Filter

The filter, usually located at the front of your machine, should be emptied and cleaned monthly. Your user manual will depict exactly how to do this.

In general, you should remove the emergency drain tube, take the top off and let the water drain into a tub.

If you have a larger opening, lay down a towel below this. Remove the plug and let the excess water drain out. You may find gunk, fluff, and other debris over this filter. Clean this in the sink with hot soapy water before replacing it.
