This machine has been working flawlessly for almost a year, then we had an extended power outage (days - Hurricane IKE). After power was restored the "clean" light was blinking. I have run it through the cleaning cycle twice using the kitchen aid cleaning fluid and now it starts to make ice, bin gets several sheets in it and then quits harvesting. The evaporating plate just builds up a 1 inch plus thick sheet that won't harvest. I have to shut it down, let it thaw, then when I restart things seem normal for a bit, it makes several sheets of ice and harvests them properly, then the harvesting stops again and a super thick sheet of ice builds up again. What could be wrong? Do I need to take it apart and clean it better?

Turns out I had a small bit of scale on the edge of the evaporator tray which was preventing some slabs from sliding off correctly, once I cleaned it with a scotch-brite pad and the cleaner solution it worked like a champ!
