ABSTRACT:
A refrigerator with a water dispenser for dispensing water from a source of water through a user accessible water outlet. The water dispenser can include a water valve, a dispensing actuator, and a water dispensing control connected to the water valve and to the dispensing actuator to control operation of the water valve. The water dispenser can include a microcontroller including a user operable calibration routine to determine a calibrated flow rate based on the time to dispense a standard quantity of water, and a non-volatile storage to store the calibrated flow rate. The microcontroller can store the most recent calibrated flow rate in the non-volatile storage. The water dispenser control can include a measured fill mode of operation. The microcontroller can be arranged to calculate a measured fill time to dispense a user selected amount of water based on the calibrated flow rate.
