At the simple inputs level, users are unable to indicate whether or not a dishwasher is present in their house. A dishwasher is assigned to the house if the user indicates that they own a clothes washer. The default value for the daily gallons of hot water used by the dishwasher is set at the time of dishwasher assignment. In the Detailed inputs users can indicate the presence of a dishwasher and the number of loads washed per week.
