Abstract
An appliance includes a dispenser having a water valve for controlling a flow of water through the dispenser and a flowmeter for measuring the amount of water dispensed through the dispenser, and a controller operatively coupled to the water valve and the flowmeter. The controller is configured to receive an input relating to a target volume of water, adjust the target volume for a volume error correction to obtain an adjusted target volume, wherein the volume error correction is based on a flow rate, open the water valve, determine a total volume dispensed using the flowmeter, and close the water valve when the total volume dispensed equals the adjusted target volume.
