If she were smart, she would have used the movement of the machine to help reposition it instead of shutting it off. What can happen in situations like this is that the wild gyrations of the tub can pull the big boot loose from its retaining ring which is like a BIG giant worm gear hose clamp. The big boot covers the opening in the bottom of the outer tub and if the clamp is pulled loose, the next time the washer starts to fill, all of the water falls right out onto the floor.
These machines without an OOB switch have blocked doors as they moved around. The first models of the WP-built 33" combo had too flexible a brace that was supposed to activate the switch that returned the machine to tumble if it started spinning with a very unbalanced load. The brace flexed instead of staying rigid and transmitting the motion to the switch so the combo would walk and more than several doors were blocked with a several hundred pound monster wedged against them before WP did some retro-fitting. I am sure WP paid for some carpentry work when the only way to get to the machine was to remove the door frame.
