An automatic liquid level control is provided for an automatic washing machine which measures the volume of liquid required to be added to the tub to increase the liquid level in the tub by a predetermined increment. The measured amount is compared to a reference amount corresponding to an empty tub. When the measured amount equals the reference amount, the clothes in the washer will be covered and the control terminates introduction of the liquid into the tub and continues with the remainder of the washing cycle.

A method of automatically charging optimum amounts of liquid in a liquid treatment machine comprising: (1) placing materials to be treated in a container in the machine; (2) filling the container to a predetermined minimum level; (3) measuring the incremental volume of liquid required to increase the liquid level in the container by a specific depth increment; (4) comparing the measured incremental volume with a predetermined incremental volume for that particular level in the container; (5) continuing the introduction, measuring and comparison of the incremental liquid volume until the measured volume is greater than the predetermined volume; and (6) terminating the introduction of liquid into said container after said measured volume is greater than the predetermined volume.
