The motor coupler may be broken. Many Whirlpool®-manufactured washers use a small, relatively inexpensive motor coupling. It's plastic and rubber and is mounted to the shaft of the motor on one side, and to the transmission on the other. Over time, the coupler wears out and fails. You may need to replace it.

clutch could be it check if nothing is jammed between tub andbasket. if u have an oily tranny i would replace it

This sounds like the motor coupler has broken.

First check the hoses to the machine. If they leak the water follows the hoses and drips on floor. Also check the hose connection at the washer. They will leak inside. Next it may well be a water pump going out or the plastic hose that is under pressure when operating. The pump is in the middle of machine underneth - Sorry - Good luck

The problem is simple and inexpensive to fix. The agitator dogs are worn and need to be replaced. The following link explains:
