A method for controlling a laundry treating apparatus is disclosed. In a washing step, the presence or absence of entangled laundry is detected using at least one of a vibration value of a drum, a current value applied to a drive unit, and an RPM value of the drum, and a step of untangling the entangled laundry is performed using at least one of a vibration value of a drum, a current value applied to a drive unit, and an RPM value of the drum.

A laundry treating apparatus includes a cabinet, a tub, a drum, a water supply, a drain, a rotator rotatably disposed on a bottom surface of the drum, and a controller that controls rotation of the rotator. The rotator includes a bottom portion positioned on the bottom surface, a pillar protruding from the bottom portion toward an open surface, and a blade including a plurality of blades disposed to be spaced apart from each other along a circumferential direction of the pillar. The blade extends from the bottom portion toward the open surface in an inclined direction with respect to a longitudinal direction of the pillar. The rotator performs a first rotation for generating an ascending water flow and a second rotation for generating a descending water flow. The controller controls the rotator to alternately repeat the first rotation and the second rotation.

An apparatus and method for reducing displacement of a washing machine having a drum rotatable about an axis of rotation is disclosed. The washing machine comprises a chassis and a motor for rotation a drum. The drum is suspended from the chassis by a suspension. The suspension can comprise springs having six natural frequencies that can resonate at a rotational speed of the drum driven by the motor. The suspension system can be tuned such that resonant frequencies can be varied based upon rotational speed of the drum.

Disclosed is a method for controlling a spin-drying cycle of a laundry treatment machine. The method includes performing a plurality of spin-drying operations by rotating a drum above an adjusted rotational speed range configured to adjust disposition of balls within a ball balancer so as to correspond to a changed amount of eccentricity, and adjusting the disposition of the balls within the ball balancer by rotating the drum within the adjusted rotational speed range, between the respective spin-drying operations.

A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A motor assembly selectively rotates the wash basket, a drain pump assembly selectively drains wash fluid from the wash tub, and a camera assembly is used to monitor an out-of-balance value to minimize out-of-balance issues. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain one or more images of the wash chamber, analyze the one or more images using a machine learning image recognition process to determine the out-of-balance value of the load of clothes in the wash basket, and perform a cloth redistribution process based at least in part on determining that the out-of-balance value is greater than a predetermined out-of-balance threshold.

Washing machine appliances and suspension assemblies for suspending tubs in washing machine appliances are provided. A suspension assembly includes a frame, a mount seated on the frame, and a rod coupled to the mount. The rod is rotatable about a pivot point. The suspension assembly further includes a sensor assembly operable to monitor rotation of the rod. The sensor assembly includes a sensor and a reference surface. One of the sensor or the reference surface is coupled to the rod and rotatable with the rod relative to the other of the sensor or the reference surface. The sensor is operable to measure reference distances from the reference surface.
