I'm not too familial with these icemakers and could use some advice. The customers complaint is "intermittent operation". I plugged the unit in and it started draining water until empty and that's it. The control panel inside the unit is stuck in the "on" position with the green light above it constantly on. You can't turn it off or change to other functions with the control panel buttons.
Is the unit looking for something else before it starts to respond such as water supply, etc?
