Abstract
The dishwasher of the present invention is adapted to skip a drain cycle if the water in the dishwasher is clean enough. The invention uses a turbidity sensor to sense the turbidity of the water. If the sensed turbidity is below a threshold value, the drain motor and the water valve are disabled to prevent the water from being drained and to prevent additional water from being introduced into the dishwasher.
