  The GE Spacemaker GSM1800NWW is a basic energy-efficient compact dishwasher that fits into a space a minimum of 18" wide; It should handle a moderate number of dishes for a household of up to three or possibly four people, although fitting in large pots and pans could be challenging. It has a simple mechanical dial that must be turned clockwise through the possible settings (heavy, normal, etc.) to reach the desired wash cycle; two plastic utility shelves (in addition to the standard silverware basket) for small items; and removable upper and lower racks.

Models: GSM100NWW (White), GSM1800NBB (Black), GSM1800NSS (Stainless Steel)
