Abstract
An apparatus and method for detecting an imbalance in the laundry load and effecting a redistribution of the imbalance by reducing the rotational speed of the treating chamber such that part of the load may redistribute while part of the load remains satellized, without ceasing rotation, and increasing the rotational speed back to a spin speed after redistribution.
Claims14
A method for operating a laundry treating appliance having a rotating treating chamber for receiving laundry for treatment, a motor rotating the treating chamber, and a controller operably coupled to the motor to control the rotation of the treating chamber according to a cycle of operation, the method comprising:
- a) rotating the treating chamber at a spin speed, which is a rotational speed sufficient to satellize the laundry in the treating chamber;
- b) determining a presence of an imbalance in the laundry;
- c) reducing the rotational speed of the treating chamber without ceasing the rotation of the treating chamber when the presence of an imbalanced is determined;
- d) monitoring the magnitude of the imbalance in a frequency domain during the reducing of the rotational speed;
- and
- e) increasing the rotational speed of the treating chamber to a spin speed in response to a reduction in the magnitude of the imbalance.
