Why does my washing machine smell like sewer?

Top 5 Reasons & Solutions Why your washing machine smell like sewer

Cause1. Rubber seal

If you have a front load washer there’s a good chance it’s the bellows, the technical name for door gasket.

The rubber seal captures the water in the washing machine especially when it cycles,  Residual water can pool there and grow bacteria. Smells awful.

If you leave your washing without cleaning the debris and dirt will collect under the rubber seal and your washing machine may smell bad.

To clean the dirt in the rubber seal:

1. use a bleach-based cleaner and soft cloth to wipe down all the folds of the seal and inside the rubber seal until you see the dirt is done.

Note: instead of shutting the door just keep it open like that allows fresh air in down to keep that rubber seal dry.

Cause2. Drain tube

The most likely explanation is improper venting of your washing machine’s drain pipe. Every drain in your home connects and eventually to the sewer.

Washing machine waste and sink waste go into what is called the “sanitary sewer.” Human waste products go into another sewer system.

Under your sink, there is a “U” shaped bend in the pipe. This is normally filled with water to prevent the backup of odors from further away.

You may want to have someone disconnect and empty that portion of the plumbing. You will also want to fill that with water which normally should occur when you use your sink.

No extra effort to that is required. The line may, for some reason, be empty.

Gases build-up, up as waste and food particles are putrified in the water-filled pipes.

When plumbing is installed properly these gasses are vented through pipes that extend up through your roof.

Drain traps are designed to prevent these gasses from coming out of your drains by maintaining a water/vapor seal.

If these are not installed properly sewer gasses enter your home.

What that water trap does is retain water in the drain tube well guess what you only do laundry you’re only doing

laundry maybe a couple of times a week.

sometimes that water there will sit there for days and it starts to run a matter of fact if you pull this hose out sometimes you’ll see black muck at the bottom of the hose.

lint and dirt build-up in the washing machine, and it needs to be cleaned out of the drain pipe

To clean the drain tube:

1. Take about a cup of bleach pour it right down in the hole where is the drain tube located.

2. Let it sit for a day.

Why should a washing machine be cleaned?

If the washing machine is not cleaned for a long time, the bacteria will generally exceed the standard. Especially the interlayer of the inner and outer cylinders is the hardest hit area of ​​bacteria.

Its dirt is mainly composed of five types of garbage:

  • scale composed of calcium ions and calcium carbonate in tap water
  • free matter of laundry detergent (soap powder)
  • the fiber of clothing; organic matter of human body
  • gray matter and bacteria brought into clothes
  • Other substances.

First of all, the washings in the washing machine itself are accompanied by many microorganisms such as sweat, hair, human secretions, etc.

These microorganisms are partially decomposed by washing, forming fibrous debris of the washed clothes, organic residues of the human body, and remaining in the washing machine.

The inner layer, secondly, the difference in the washing supplies will also cause the difference in the dirty layer of the washing machine.

The washing powder on the market today is divided into two types: ordinary powder and concentrated powder.

Boric acid and fluorescent whitening agents are added to the ordinary powder. These ingredients are easy to condense with the organic matter on the clothes to form dirt and remain in the interlayer of the washing machine.

The concentrated washing powder has enhanced the decomposition ability of the clothes stain due to the addition of some surfactants.

Some, but some partially decomposed stains will adhere to the washing machine interlayer, in addition, some calcium ions in the water, combined with the organic matter on the clothes, easily from dirt, which is also a reason for the dirty layer of the washing machine.
