    1. Stop the washer and check the drum and the drain filter for foreign objects.
    LG Customer Information Center If the noise continues after restarting, contact LG service. Contact: 1-800-243-0000 or lg.com/us/support.

  2. The wash load is unbalanced (thumping). Source: Troubleshooting: Noises, p. 44

    1. Pause the cycle and redistribute the load after the door unlocks.

  3. The shipping materials were not removed (vibrating or squeaking). Source: Troubleshooting: Noises, p. 44

    1. Remove the packaging as described under Unpacking and Removing Shipping Material in the Installation section.

  4. Not all leveling feet rest firmly and evenly on the floor. Source: Troubleshooting: Noises, p. 44

    1. Level the washer (Level the washer below).

  5. The floor is not rigid enough. Source: Troubleshooting: Noises, p. 44

    1. Make sure the floor is solid and does not flex (manual section Flooring, Installation).

  6. Plumbing in the home moves or flexes when the water valves in the washer shut off (banging noise while the washer fills; water hammer). Source: Troubleshooting: Noises, p. 45

    1. Install water hammer arrestors between the fill hoses and the washer. LG says water hammer is a home plumbing effect and not a washer defect.
