There is a tube that brings water to the ice maker running up the back of my freezer. It attaches into a white rectangular plastic piece. It has been spraying water out the back and making ice cubes that are half their normal size. I took it apart, seemed like the tube had come out. Put it back in all the way, put the metal clamp back on and now it is shooting water. The tube itself doesn't have a leak. Not sure what to replace. The parts involved are the plastic water tube which has a metal piece in the end of it that connects to the top of the freezer, a white soft plastic tube that the water tube goes into, and a rectangular white hard plastic piece that the soft white plastic tube goes into. Any help would be appreciated.

Thanks!
