A method for washing objects automatically provides the taking of turbidity measurements before and after a portion of water is removed from the dishwasher. This partial drain allows first and second magnitudes of turbidity characteristics, taken before and after the partial drain, to be compared to each other for an analysis of the degree and/or character of particulates within the water of a dishwasher. In certain applications of this method, the turbidity characteristics can be the absolute magnitude of turbidity, the rate of change of turbidity, the absolute magnitude of turbidity variability and the rate of change of the absolute magnitude of turbidity variability. The portion of water removed between the two sets of readings that yield the first and second magnitudes of the selected characteristics is less than the total amount of water within the dishwasher.

[ The embodiments of the invention in which an exclusive property or right is claimed are defined as follows:] [1.] A method for washing an object, comprising:providing a container;disposing said object within said container;starting a first washing cycle by providing an initial quantity of water within said container, said cycle being the period from fill to near complete drain of said water in said container;causing said water to contact the surface of said object;periodically measuring the turbidity of said initial quantity of water while said water is being caused to contact said surface of said object to provide a series of turbidity measurements over time;calculating a first magnitude of a first turbidity characteristic from said turbidity measurements of said initial water quantity;removing a first portion of said initial quantity of said water from said container to obtain a remaining portion, said first portion being less than said initial quantity;measuring the turbidity of said remaining portion;calculating a second magnitude of said first turbidity characteristic from said turbidity measurement of said remaining portion; anddetermining the degree and character of particulates within said water as a function of the difference between said first and second magnitudes of said first characteristic of said turbidity measurements; andbased upon said determination of degree and character, either removing from the container a second portion of the remaining portion, removing from the container all of the remaining portion, or proceeding with the remaining portion contacting the surface of the object.
