1. A laundry washing machine, comprising:
a wash tub disposed within a housing;
a water inlet configured to dispense water from a water supply into the wash tub;
a fluid level sensor configured to sense a fluid level in the wash tub; and
a controller coupled to the water inlet and the fluid level sensor, the controller configured to generate a calibration factor associated with a water pressure of the water supply to which the water inlet is coupled by performing a calibration process that controls the water inlet to dispense water into the wash tub while the wash tub is empty and determines a time to reach a predetermined fluid level sensed by the fluid level sensor;
wherein the controller is further configured to set one or more operational settings for a wash cycle using the generated calibration factor.
