LG refrigerator LRFXC2416S won't drop ice into bucket.

I have an LG refrigerator model LRFXC2416S with an in-door ice maker that won't drop ice into bucket. If I remove the ice bucket and press the test button on the ice maker, the ice tray rotates completely and drops ice. It then returns to home position and fills with water. The water freezes and stops. I have to manually dump the ice by using the reset button. The craft ice maker is working OK,
