Abstract
In a control device for an automatic washing machine, a first change in the turbidity of a wash liquid is detected a predetermined time period after start of a wash step. The predetermined time period corresponds to a time period required for the detergent to sufficiently dissolve into the water. A time period of the wash step is determined on the basis of the detected change of turbidity. The wash step is completed upon lapse of the determined time period when a second change in the turbidity of the wash liquid in a short period upon lapse of the wash step time period is at a predetermined value or below. When the turbidity change is above the predetermined value, the wash step time period is extended by a period of time in accordance with the first change in the turbidity.
