Patent ID: 8615833

Claim:
A washing and water recirculation method for a washing machine comprising: supplying liquid to a tub until it reaches a predefined level; continuously recirculating the liquid inside the tub with higher outflow out of the tub than a liquid drain basket's outflow to the tub; monitoring a liquid level in a pool of the tub, wherein the pool is formed as a recess in the bottom of the tub; recirculating the liquid with a constant outflow out of the tub until the liquid level in the pool reaches a minimum liquid level and a liquid level of the liquid drain basket reaches a maximum liquid level; in response to determining the liquid level in the pool is at a minimum liquid level, controlling a speed of a pump for recirculating the liquid to continuously recirculate liquid in the tub so that the outflow out of the tub is equal to the liquid drain basket's outflow to the tub; moving agitator elements to effect a washing operation; draining the liquid from the tub; and spinning the liquid drain basket to effect centrifugation.
