This paper describes a dishwasher ground test unit which has been designed to wash eating utensils in the microgravity environment of the Space Station. The basic wash process is described as well as the methods used for controlling the wash and rinse water. The required interfaces to the Space Station are discussed and the amount of resources consumed during a complete wash cycle are presented. The paper is concluded with a discussion of several growth versions of the dishwasher which will accommodate increases in the number of crew persons on board the Space Station.
