Abstract

A method of operating a laundry treatment appliance includes supplying a first predetermined volume of water to articles within a wash chamber; performing a first agitation phase after supplying the first predetermined volume of water to the articles; performing a first drain phase after performing the first agitation phase. The first drain phase includes draining a first predetermined portion of the first predetermined volume water such that a level fill volume of water remains within the wash tub. The method further includes supplying a second predetermined volume of water to the articles within the wash chamber, the second predetermined volume being less than the first predetermined volume, wherein the second predetermined volume and the level fill volume together define a rinse volume of water.
