  • Publication number: 20080016900
    Abstract: An ice maker includes a refrigeration system for cooling an ice forming surface, a water supply inlet and an inlet valve arranged to selectively admit and prevent admission of water from the inlet. A flow sensor at the inlet valve determines a volume of water admitted through the water supply inlet. An operating position of the water supply inlet valve is based upon input from the flow sensor. A water collecting device receives a supply of water from the water supply inlet through the water supply inlet valve and receives a flow of water from the ice forming surface. A recirculating pump is connected to the water collecting device and to a recirculating passage arranged to direct water toward the ice forming surface. A level sensor at the water collecting device determines a level of water in the water collecting device. A discharge pump is connected to the water collecting device, and the control selectively operates the discharge pump based upon input from the level sensor.
