Title: PRE-DRAIN UNBALANCE DETECTION IN A WASHING MACHINE
Abstract:
A method of sensing unbalance in a washing machine due to unbalance of a wash assembly includes filling a tub of the wash assembly with water, agitating contents of the tub, and initiating an unbalance detection spin prior to draining the water from the tub. During at least a portion of the unbalance detection spin, sensor data is obtained from a sensor mounted to a portion of the washing machine. An unbalance parameter is obtained from the sensor data to determine whether a high dynamic unbalance condition is detected. If a high dynamic unbalance condition is detected, the contents of the tub are redistributed by agitating the contents of the tub in the water.
