A power controller for an appliance, especially a washing machine, is operative to place the appliance into a hyperspin mode. When in the hyperspin mode, the washing machine rotates its washing basket at a higher speed in relation to a traditional spin mode for the washing machine. In order to prevent damage to the washing machine that could result from spinning heavier, unbalanced loads at higher speeds (i.e. hyperspin speeds), a controller detects vibration of the washing machine basket while the items are being spun at a lower speed (i.e. at the speed of the traditional spin mode). If the washing basket vibration is less than a predetermined threshold vibration value, the washing machine controller operates to cause the washing machine to rotate its washing basket at a higher speed. This results in removal of more water from the clothes being spun dried.
