I have the SPT IM-100 Portable Ice Maker. After about 2 months, it stopped, telling me that it needed water, when of course it was full of water. I did alot of digging on the Internet to find a solution. There was none. It finally occurred to me that the water sensor might be calcified with our hard water here in Reno. BINGO!!!! I ran several cycles with lemon juice and vinegar (you pick your favorite non-toxic acid), and the damned thing started up again as if brand new.
