<p>A dishwasher is provided with a washing tank for accommodating an object to be washed, a washing unit for washing the object to be washed in the washing tank, a water-supply system for supplying wash water into the washing tank, a drainage system for draining the wash water from the washing tank to the outside of the dishwasher, and a drainage pathway which is provided in communication with the drainage system. Also, the dishwasher is provided with a turbidity detection unit which detects the information associated with the turbidity of the wash water in the drainage pathway and which is provided to the drainage pathway, and a control unit for changing and controlling the operation conditions of the washing unit according to the information associated with the turbidity of the wash water detected by the turbidity detection unit. The control unit compares the values detected by the turbidity detection unit in either a state in which there is no water or a state in which there is the water after the water supply by the water-supply system at the start of the operation. As a result, the dishwasher determines whether or not the value detected by the turbidity detection unit in the state in which there is the water is adopted as the reference value of the information associated with the turbidity of the wash water.</p> |
