Abstract
A method and apparatus for breaking a unit dose package in a chamber within a post located in a basket of a laundry washing machine. The method includes filling the basket and the chamber, increasing a rotation speed of the basket and/or the post to raise the water level in the basket and lower the water level in the chamber to cause a unit dose package within the chamber to move downwards; reducing the rotation speed to lower the water level in the basket and raise the water level in chamber to cause the unit dose package within the chamber to move upwards; and repeating the steps of increasing and reducing the rotational speed to cause the unit dose package to break open and at least partially dissolve. A laundry washing machine configured to perform this process is also provided.
