Abstract: This invention relates to an automatic batch washing machine where the potential product or products that are being cleaned includes, but is not limited to, clothes and dishes. The machine combines user input and data gathered from sensors to operate to automatically dispense all necessary cleaning and treatment chemicals at proper times and optimally measured doses. Manual measurement and insertion of requisite chemicals has been eliminated. Efficiency and performance are enhanced through the use of optimally measured, timed and placed chemical dispensions. The chemical supply containers incorporated in conjunction with the machine are marked in such a way that they can only be inserted in a certain location in conjunction with the machine eliminating the possibility of mistakingly locating one chemical in a dispensing location for another chemical.
