23. A dishwasher, comprising: a container for accommodating a plurality of articles; a circulation pump for distributing a liquid to the container; a temperature sensor for sensing temperature of the liquid being distributed and providing a signal representation thereof; a turbidity sensor for sensing turbidity of the liquid being distributed and providing a signal representation thereof; and a controller, responsive to both the temperature and turbidity sensors, for adjusting an operating cycle of the dishwasher according to the liquid temperature, the liquid turbidity, and the rate of change of liquid turbidity, whereby the operating cycle is adjusted as a function of the liquid temperature, the soil level of the articles, and the soil removal rate from the articles.
