Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Open the water faucet fully

    Check that both hot and cold water supply faucets behind the washer are fully open.

    Turn faucets counterclockwise to open. Both must be on for proper operation.

  2. 2

    Inspect supply hoses

    Check both inlet hoses for kinks, bends, or damage. Straighten any restrictions.

    Pull the washer out slightly to access hoses. Avoid sharp bends.

  3. 3

    Clean inlet filter screens

    Turn off water, disconnect hoses at the washer, and clean the small mesh screens with a toothbrush.

    Sediment buildup on these screens is very common in areas with hard water.

    Tools required
