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.

Electromechanically actuated turbidity sensor for a machine for washing

A machine for washing articles is provided with a wash process sensor that is capable of measuring a plurality of physical parameters that relate to the progress of a washing procedure. The wash process sensor also monitors the changes in the measured parameters and calculates a value that represents the degree of cleanliness or dirtiness of the articles being washed. In one embodiment, the wash process sensor also directly controls a plurality of devices, such as motors, heaters, dispensers and valves, to directly control the washing process.
