Abstract
A method of detecting high friction events in a laundry treating appliance includes rotating the drum, determining, during the rotation, a torque of the motor, an acceleration of the drum, a speed of the drum, and/or an angular position of the drum at each of multiple speeds, and repeatedly estimating with a parameter estimator, during the rotation, viscous friction, coulomb friction, and total friction based on the torque, acceleration, speed, and/or angular position of the drum. A high friction even is determined based on the estimated viscous friction, coulomb friction and/or total friction.
