2. Place the level on the edge of the washer's top cover. Place it perpendicular to the washer's face panel. Observe the reading on the level.
3. Move the washer away from the wall a few inches if it needs to be leveled. Tip the washer back and slip the block under the front to hold the front feet off the floor. Loosen the lock nuts with the wrench, then turn the feet in or out as dictated by the level readings you saw in Steps 1 and 2.
