A:Answer It sounds like the shipping bolts were not removed from the LG 4.5 Cu. Ft. 12-Cycle Front-Loading Smart Wi-Fi Washer with Steam and 6Motion™ Technology - Graphite Steel, Model # WM3700HVA. The shipping bolts can be located in the back of the washer. Starting with the he bottom two shipping bolts, use the wrench (included) to fully loosen all four shipping bolts by turning them counterclockwise. Remove the bolt assemblies by wiggling them slightly while pulling them out. Save the bolt assemblies for future use. To prevent damage to internal components, do not transport the washer without reinstalling the shipping bolts. Failure to remove shipping bolts and retainers may cause severe vibration and noise, which can lead to permanent damage to the washer. The cord is secured to the back of the washer with a shipping bolt to help prevent operation with shipping bolts in place. See page 12 of your owner's manual for instructions on how to remove the shipping bolts...^IFV
