Let’s get started.

Why does the washer drain smell like sewage?

Bad smell from the washer drain may occur due to various factors such as accumulation of detergent & dirt residues, mold & mildew (bacteria) formation, lint accumulation, greasy substances, limescale, etc.

If you miss inspecting the drain area of your washer, it may result in clogging as dirt and debris just build up over time.

If the clogging issue goes unaddressed, it will eventually lead to a foul smell from the washer and drain areas.

Let’s take a quick look into the key factors that may trigger a bad smell in the washer drain.

Mold & Mildew

Mold and Mildew are usually formed due to dirt and detergent residues that are kept uncleaned for a longer time.

As a result, bacteria not only survive but thrive.

These bacterias produce a bad odor from the washer and the drain areas.

Lint accumulation

The tiny fibers from the fabrics build up over a period of time.

Furthermore, it also attracts greasy substances from the food stains present on your clothes.

This again promotes a suitable environment for the bacteria to survive and produce unpleasant odors around the washer.

Heavily soiled clothes

Loading heavily soiled clothes into the washer results in an accumulation of adamant dirt residues inside the washer that is further released through the drain.

These residues build up over time into the drain area which eventually leads to a bad smell and decreased performance of your washer.

Clogged Sewage

This is another factor that promotes bad odor.

The drain pipe that releases wastewater is usually attached to the sewage system, if the sewage system has been clogged then there is a possibility of sewage water running through your drain pipe.

Detergent and fabric softener

Using a poor quality and improper quantity of detergent and the fabric softener may result in a lot of suds and residues.

These residues happen to stay inside the washer for a long time due to constant build-up, thereby producing a bad smell from the washer and drain areas.

How to get rid of the bad smell from the washer drain?

The best way to get rid of the bad smell from your washer and the drain area is to clean them thoroughly.

There are 2 ways to deal with bad smell:

  1. By Using readily available cleaners
  2. Homemade cleaners

Readily available cleaners

Simply add the appropriate quantity of the solution to the washer and run a clean or an empty cycle with the hottest temperature.

This will not only clean the washer but also effectively clean the drain areas since the cleaning solution gets to flow through the drain areas as well.

For thorough cleaning of the drain areas, you may detach the drain pipe and clean it using the solution with hot water.

Also, you will have access to the drain valves which cannot be ignored, therefore use a soft brush to clean the connected drain valves as well.

Homemade cleaners

You don’t need any special preparation for this.

Simply add 2 cups of baking soda or Vinegar to the washtub and run an empty cycle using hot water.

Then, let it run for about 60 minutes.

Once you are done with the above step, detach the drain hose and clean them using the same solution, here’s how:

  • Make a paste using water and baking soda and apply it to the drain areas using a toothbrush.
  • Let the solution settle for about 15 minutes.
  • Now clean the drain hose with hot water.
  • Re-attach the drain hose.

Note: If the area is not cleaned effectively and is still releasing a bad smell, you may have to repeat the wash and clean process. As an alternative, you may use 2 cups of liquid bleach and run an empty or clean cycle with hot water.

The above methods will not only clean your washer and the drain areas but also remove the bad smell.
