A dishwasher appliance is provided, and includes a control device configured to direct one of a series of automatic wash programs to be executed by the dishwasher appliance. Each successive automatic wash program within the series corresponds to an increased soil level of dishware to be washed with respect to the previous automatic wash program within the series. The control device is further configured to determine an elapsed time between a first and second uses of the dishwasher appliance and to select the one of the series of automatic wash programs in response thereto upon the second use, whereby, as the determined elapsed time between first and second uses increases, the selected automatic wash program within the series correspondingly progresses along the series. Associated methods are also provided.
