What causes mold in my washing machine?

Cleaning mold out of your washing machine is only helpful if we know what causes mold to form in the first place. Once cleaned, it’s important to make steps to prevent it from coming back.

Moisture in the washing machine

The number one cause of mold in washing machines is from moisture sitting too long. Not letting your washing machine dry properly between uses can create the perfect environment for mold to form. This moisture can hang out in the washing drum, rubber seal and detergent drawer, ultimately anywhere that is damp and dark.


  • After each washing cycle, leave the washing machine door open slightly. This will allow the machine to air dry when not in use.
  • Wiping the seal dry after each use can also help prevent mold from growing.

Leaving wet clothes in the washing machine for too long

Washing machine that uses HE detergent

Using the wrong detergent

Most new washing machines now display the initials HE (High Efficiency) on the machine. If you see this image on your washing machine, you need to be sure you’re using the correct laundry detergent. Using non-HE detergent in your HE washing machine can create too many suds. If this happens, the machine can have a hard time fully rinsing the soap out on the rinse cycle. If this happens, the additional soap residue can lead to a perfect scenario for mold to form.

The difference between HE and non-HE washing machines is that HE machines operate much more efficiently. This higher efficiency means that it requires special and less detergent than a non-HE machine.
