Does Your Washing Machine Smell Like Rotten Eggs? Five Common Causes and Solutions to Fix It

by My Modern Cave

If you open your washing machine and are greeted with a smell like rotten eggs, don’t panic. This is a common problem that can be fixed relatively easily. It’s likely due to a build-up of bacteria in the machine or caused by a buildup of sulfur in the water.

When your washing machine smells like rotten eggs, it is usually due to the presence of hydrogen sulfide gas. This gas is produced by bacteria that are present in the machine. The bacteria thrive in moist environments, especially in sewers, and they release the gas as a by-product of their metabolism. The gas is highly flammable and can be explosive if it builds up in a confined space.

This article will give you five reasons why rotten egg smell comes from your washing machine and solutions to the problem. Let’s get started.

5 Reasons Why Your Washing Machine Smells Like Rotten Egg

1) Your Machine’s Door Seal is Filled With Mildew, Mold and Dust

Although this may seem like a small problem, it can actually cause big problems for your machine. Mold and mildew can cause your machine to rust and corrode, which can lead to expensive repairs. Not to mention, the smell is incredibly unpleasant. Luckily, there are a few things you can do to clean your door seal and get rid of them.

You can either clean it yourself with a mixture of vinegar and water or you can buy a commercial cleaner specifically designed for mold and mildew. Either way, getting rid of them will help prolong the life of your washing machine and keep it smelling fresh.

2) Your Sewer May be Clogged

This can be a serious problem, as it can lead to backups and overflows. A clogged sewer can also be a health hazard, as it can release dangerous gases into your home. It can cause a variety of problems, including bad smells, overflowing toilets, and backups. A clogged sewer can be caused by a variety of things, including tree roots, grease, and debris. If you think your sewer is clogged, you should call a plumber to have it checked out.

  • First, try using a plunger to see if that will unclog the drain.

  • If neither of those work, you can always call a plumber.

3) Your Drain Plug May be Clogged

A clogged drain plug can cause water to back up into the machine, and that water can become stagnant and produce a foul odor. The situation can cause water to build up and create a breeding ground for bacteria. This can lead to a foul smell in your washing machine.

4) You Use non-HE Detergent

Non-HE detergent can leave behind a residue that smells bad and is difficult to remove. HE detergent is specially formulated to work in high-efficiency washing machines and doesn’t leave behind a residue. It’s also more effective at cleaning clothes. Switching to an HE detergent will eliminate the bad smell from your washing machine and make your clothes cleaner.

5) You Don’t Close Door After Every Wash

While it’s not necessary to do this, it does help to keep the machine clean and free of odors. By closing the door, you prevent moisture and dirt from getting inside the machine where they can cause problems. By keeping the door closed, you prevent bacteria and mold from growing inside the machine. Not only will this help keep your machine smelling fresh, but it will also help extend its life.

Four Tips to Prevent Rotten Egg Smell in Your Washing Machine

1) Use Generous Amount of Detergent

Not using enough detergent can cause a build-up of dirt and grime, which can lead to odors. To avoid this, be sure to use the recommended amount of detergent for your load size.

2) Wash Regularly at 60° C

You need to wash your clothes regularly at 60 degrees Celsius. This will kill any bacteria that might be causing the bad smell. You should also clean the washing machine’s door seal and drum regularly to make sure there is no build-up of dirt or grime.

3) Occasionally Wash Drum with Hot Water Mixed With White Vinegar


Your machine needs to be cleaned occasionally. Over time, lint, dirt, and soap scum can accumulate in the nooks and crannies of your washer, causing it to smell musty. If you notice your machine starting to smell, make sure to give it a good cleaning with hot water and white vinegar. White vinegar is a natural disinfectant and will help to remove any bacteria that may be causing the odor.

4) Clean Drain Filter Periodically

The drain filter is responsible for trapping debris and lint, and if it gets full, it can cause your washing machine to smell bad. To clean the drain filter, simply remove it and scrub it with a brush. You should also make sure to clean the area around the drain filter so that there is no build-up of dirt and grime.

5) Don’t Leave Wet Cloths Long

Avoid leaving wet laundry in the machine for too long as this can also cause bacteria to grow. If your washing machine does start to smell, there are a few things you can do to remove the odor.

  • First, try running an empty cycle with hot water and vinegar. This can help break down any residue that may be causing the smell. If the vinegar smell is too strong, you can try using baking soda instead.
  • Run another empty cycle with hot water and either baking soda or vinegar to remove the odor completely.
