We love our ice maker, other than the constant buildup of black and red mold in the back of the unit where you are unable to reach it. When we had a repairman out for a separate issue (that was taken care of under warranty), he indicated ours was cleaner than most and that there's no way to clean it other than by completely disassembling the unit. He tried to convince us that it doesn't touch the ice, but during the cleaning process today, it's clear the mold is spreading to areas touched by water/ice. I live in a very dry state with no added humidity in the air and the mold formed before the first cleaning cycle, and we run the cleaning solution through it more frequently than recommended. I've had the unit for almost three years now and love the ice, but am concerned about the health effects of ingesting moldy ice.
