1. A laundry washing machine, comprising:
a wash tub disposed within a housing;
a water inlet configured to dispense water into the wash tub, the water inlet including a hot water valve and a cold water valve respectively configured to control a flow of hot water and a flow of cold water into the wash tub;
a weight sensor positioned to sense at least a portion of a weight associated with the wash tub; and
a controller coupled to the water inlet and the weight sensor, the controller configured to:
determine a weight associated with the wash tub using the weight sensor after a load has been added to the wash tub,
determine a target temperature of water to be added to the wash tub,
determine, based at least in part on the determined weight associated with the wash tub, a volume of hot water and a volume of cold water to be added to the wash tub to provide the determined target temperature of water in the wash tub, and
control the hot water valve and the cold water valve during a wash cycle to respectively add the determined volume of hot water and determined volume of cold water to the wash tub.
