My washer started to rock and unbalanced during spinning cycle - after removing a few towels, the washer rocks less, the spin cycle finished. Afterward, the washer is uneven, the back left foot is not springing like before. Does anyone know if the leveling mechanism failed and need to be repair or I can do a minor adjustment. I checked everywhere on manual or internet and can't find the info. Please help

Also try this: Lift the machine up an inch or more off the rear feet. Allow the machine to drop back down on them. If there is any rust issue, this should break the leveling mechanism loose.
