Abstract
A machine for washing articles is provided with a turbidity sensor that is activated by an electromechanical timer. When activated, the turbidity sensor determines the magnitude of turbidity of water within the machine for washing articles and decides whether or not to inhibit a subsequent drain operation. If the turbidity of the water is sufficiently low, the drain operation is inhibited and the machine for washing articles is prevented from purging the existing water from its interior. This allows the relatively clean water to be reused at a savings of both water and energy.
