KitchenAid KUIS18N Automatic Ice Maker
Ice maker that makes small or cloudy cubes, leaks at the base or refreezes its bin; check the filter and water line first.
Model overview
The KitchenAid KUIS18N is an 18-inch automatic ice maker that makes Clear Ice cubes and stores them in a 35 lb bin. An integrated filter treats the water before it reaches the freezing section, so a cloudy or hollow cube can point to the filter path as well as the freezer. Max Ice mode is there for busy stretches, and the door opens downward. The model is listed as discontinued, so the rating label confirms the exact version. The unit needs a grounded three-prong outlet and no extension cord. Owners in the metro areas we cover should keep that outlet in mind. For the booking form, give the full model number from the rating label, the ice problem (no ice, small cubes or leaking) and any code shown.

What sets the KUIS18N apart
Most 18-inch ice makers are separated by how they freeze and whether they filter the water. This one pairs Clear Ice production with an integrated filter and a 35 lb bin, and the drop-down door changes how the bin is reached. Day to day, the owner notices the difference in cube shape and in how often the filter needs attention. The documented KUIS18NNZW variant combines the same drop-down door, filtration and storage, so the full number decides which version is on site.
Service notes for the KUIS18N
When cubes come out small, hollow or cloudy, a technician follows the water path first: the integrated filter, the inlet line and the valve that feeds the freezing plate. Leaks at the base usually trace to the drain path or a loose fitting under the cabinet, so the owner can safely check that the floor is dry and the unit sits level. A bin that melts or refreezes into a block suggests warm air is getting into the bin area or the door is not closing fully. Before the visit, the owner can note whether Max Ice mode was on, when the filter was last changed and roughly how many cubes came out in a day. Disconnect power before cleaning any interior part.
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.
