Welcome to one of the Redwood Forums. While we may not have the same model and year, some things never change. Ours has 2 separate 1/4 turn water valves under the kitchen sink by the p traps. One is for the ice maker water line and the other is for the dishwasher. You may or may not have both valves there. Another thing to consider is the water line under or near the slide out kinked in any way? Do you have a reliable thermometer to confirm that your freezer is cold enough to generate ice? If it's not cold enough it won't make ice with or without water, just asking. Also some household refrigerators use an interior water filter. Does your refrigerator have one of these? Is it fully seated properly? If it isn't it might not be allowing the water to pass inside. Things to check out and report back please.
