coating (clear) on ice cube mold peeling off

Removed ice maker from fridge. Removed motor assembly (3) screws on cover, and (2) screws inside. Removed mold (3 screws on bottom) and replaced everything in reverse order. Note: Turned ice maker off for several days while waiting for parts. The water line on this particular model will freeze inside the freezer if ice isn't made for several hours/days. You will have to defrost to begin making ice again.
