What Are the Causes of Slime When a Washer Fills?

If you regularly wash your laundry on a low temperature, such as the warm setting -- about 90 to 110 degrees Fahrenheit -- then you risk the growth of a black jellylike slime inside your washer known as biofilm. This slime is made up of deposits of bacteria and fungi that thrive in the warm, moist environment and can cause your washer to malfunction by blocking moving parts. Knowing how to remove this slime can save you time and money in washing machine repairs.

Instructions

  1. Preventing Biofilm Growth

    • 1

      Operate your washing machine on a high heat, such as 130 degrees Fahrenheit. Although it may be more environmentally friendly to wash your clothes at a lower temperature, the risk of your washer malfunctioning greatly increases.

    • 2

      Perform a maintenance wash once a month by placing your washer on the hottest setting available with only water and detergent -- no laundry.

    • 3

      Leave the soap dispenser and washer door open after each wash to allow the inside to dry out completely. This will prevent the moist, warm atmosphere that bacteria thrive in.

    Removing Biofilm Growth

    • 4

      Wipe the soap dispenser with a kitchen towel, using a bleach or mildew remover.

    • 5

      Apply disinfectant to all tap and hose fittings and remove biofilm using a small brush.

    • 6

      Include a capful of distilled white vinegar in an empty wash on a hot cycle to remove mold and off-putting smells.
