Ice machine makes a batch of ice, harvest, drops and restarts. Makes another batch of ice, harvest, drops and restarts. But on the third time, it makes a batch of ice, goes into the harvest mode and within 5 or so seconds it starts the freeze cycle again before dropping the ice. No the water curtain never moves. Any ideas?? After the last batch of ice finally melted off (I turned the machine off), I can turn it back on and it did the same thing again. Tks.
