Abstract
A method of determining a dish load for an automatic dishwasher and a method of operating the automatic dishwasher based on the dish load. The dish load is determined by determining a first temperature corresponding to the temperature of the dishes, determining a second temperature corresponding to the temperature of a charge of water prior to a time when the charge of water contacts and transfers heat to the dishes, determining a third temperature corresponding to the temperature of the second charge of water when the temperature of the second charge of water and dishes have equalized, and calculating a temperature ratio of the difference between the second and third temperatures and the difference between the third and first temperatures.
