Abstract
A laundry washing machine and a method for operating the washing machine offer ways to load a unit dose package into a compartment of the washing machine.

The tub is then filled with hot or cold water depending on the temperature of the water in the tub, or whether a sanitizing cycle of a washing program has been selected.
