Product review (4 stars): Doesn't work with distilled water.
Works fine except on distilled water. I wanted to use distilled water to keep from getting a lime buildup from our locally hard water, but the water level sensor can't detect distilled water and the unit shuts off. Apparently, the water level works on the conductivity of the water and distilled water has a low conductivity. Adding a few grains of salt to the reservoir raises the conductivity and solves the problem. There is nothing in the instructions that addresses this and I initially thought that I had a bad ice maker.
