Water inlet valve was not supplying water to ice maker. The water inlet valve is not available/DA-03150A. Samsung was no help. Appliance Parts Pros said that part DA 81-05997A was the replacement part. This part includes the entire housing that the water filter and water holding bottle are housed in, and of course, the water inlet valve. After resetting the ice maker it started to produce ice cubes in about 12 hours.
