The back feet of these new top load washers from Samsung are not adjustable so it is very unlikely that they can be precisely leveled. This will keep the vertical axis of these "vertical axis machines" from being exactly vertical so they will work harder, i.e. use energy, to try to balance a load to spin with minimal vibration.
Best Buy and other retailers should inform interested customers that their installers or purchasers will likely not succeed in leveling these machines as directed by Samsung in the user manual and their onliine procedure.
