Keep your clothes washing machine from rocking, chattering and moving by adjusting the legs. You can level it in five minutes.
Lift the machine slightly with a pry bar to take the weight off the front legs, then turn the legs until the side of the washer is plumb.
Tighten the locking nut up against the frame of the washing machine to keep the leg from turning.
If your washing machine has been making loud thumping noises and moving across the floor when it's in spin cycle, it probably needs to be leveled. Fortunately, it's an easy fix, though you may need a helper to tilt up the machine.
Push the machine back into position if it has moved across the floor. Adjust the front legs to make the machine level across the front and from front to back (Photo 1). The legs can usually be turned by hand after the locking nut at the top of the threads is turned down, but if the threads are rusted, use a wrench.
After leveling, lock the leg into place with the locking nut (Photo 2).
If the rear leveling mechanism is frozen with rust, tap the legs a few times with a pliers or hammer to break it free.
Most washing machines have self-adjusting rear legs that level from side to side, but dirt, lint and rust may keep them from working properly. If the back isn't level, tip the washing machine up a few inches and then set it back down so the weight of the machine loosens the legs. If the machine still doesn't level out, the self-leveling support may be rusted against the washing machine frame. Tip the machine off the ground, then break the self-leveling support loose by tapping the legs (Photo 3).
