Abstract: Systems and methods for determining an out of balance condition of a washing machine are provided. In particular, a plurality of angular positions of a motor associated with a washing machine can be determined. The washing machine can include a wash tub, and a wash basket rotatably mounted within the wash tub. The motor is configured to rotate the wash basket within said wash tub. Data indicative of at least a single phase of motor current being applied to the motor can be obtained while the wash basket rotates. The data can be spatially sampled over at least a subset of the plurality of angular positions of the motor. An out of balance condition associated with the washing machine can be determined based at least in part on the sampled data.
