By nature this machine has a strong oscillation when agitating, and every machine will splash water on the low level with no clothes in the basket. That being said, your most likely culprit for intermittent leaks on this machine is the pump. Remove the cabinet and inspect the face of the pump which is toward the motor and look carefully for traces of dried water tracks under the center seal. Usually you can visualize the mineral tracks of a past leak.
Other causes for intermittent leaks are water valves which stick open once in awhile and overfill. Usually this occurs on the cold side since it is not protected from sediment as the hot side which passes thru the water heater first.
