KitchenAid KUIO18NNZS Outdoor Automatic Ice Maker
Outdoor 18-inch ice maker where the bin melts or refreezes, cubes come out small or water pools at the base.
Model overview
The KitchenAid KUIO18NNZS is an 18-inch outdoor automatic ice maker with a 35 lb ice bin and production of up to 50 lb per day. Its welded stainless steel construction is built for weather exposure, and an ice scoop comes with the unit. A status light signals when the integrated filter needs replacement, and a door-ajar alarm sounds after five minutes. The drain-hose run must stay within 10 ft, so routing is one of the first things to check. Owners in the metro areas we cover should check the filter light and the drain-hose route before a visit. For the booking form, give the full model number from the rating label, the ice problem (no ice, small cubes or water at the base) and whether the filter light is on.

What sets the KUIO18NNZS apart
Outdoor ice makers are judged by how the cabinet handles weather and how much ice the bin holds. This one uses welded stainless steel and a 35 lb bin, and its production can reach 50 lb per day. The filter status light and door alarm are simple checks that the owner sees without opening the unit. Day to day, the owner plans around the daily output and keeps the bin emptied before the heat builds.
Service notes for the KUIO18NNZS
When the bin melts into a block or the unit makes no ice, a technician checks the water line, the filter and the drain before the freezing system. A drain hose that runs past 10 ft or pools water can make the base leak, so the owner can safely check the hose length and the low point. The filter light shows when the cartridge needs changing, and a cartridge past its life can slow the ice or cloud it. Melting in the bin often traces to the door seal or a door left ajar. Keep the scoop out of the bin when the unit is not in use. Disconnect power before opening the cabinet.
The model number is printed on the rating label, usually on a side wall or the ceiling inside the fresh-food section, or behind the base grille; match it letter for letter before booking, because a single letter can change parts.
