The Washing Machine Smells
Remember, you wash your clothes to make it clean. They become clean, but if they emit an odor, can you wear them? The main reason is that you are putting the load in cold washes. The detergents can also be a problem.
Substitute cold wash with a hot wash. Then opt for regular maintenance. Seek the advice of a technician to change the detergents.
