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. A control unit controls the washing machine to add water to a compartment having a unit dose package. 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.

A laundry washing machine and method control a temperature of water used in a wash cycle based at least partially on the weight of a load being washed. A volume of hot water and a volume of cold water to be added to the wash tub to provide a target temperature of water in the wash tub may be determined and a hot inlet valve and a cold inlet valve may be controlled to respectively add the determined volume of hot water and determined volume of cold water to the wash tub.

Provided are a laundry treating device and a water temperature control method and apparatus therefor. The laundry treating device includes a cold water inlet and a hot water inlet, and the control method includes: detecting a water temperature in the laundry treating device in response to determining that warm water is to be introduced into the laundry treating device, and controlling the laundry treating device based on the water temperature to enable inflowing of cold water through the cold water inlet and inflowing of hot water through the hot water inlet alternately; detecting a water level in the laundry treating device, and controlling the laundry treating device to stop water inflow in response to determining that the water level in the laundry treating device reaches a first predetermined water level; and controlling the laundry treating device to perform washing for a first predetermined duration based on a predetermined washing cycle.
