Some of the major brands that offer 18-inch built-in dishwashers are GE, Whirlpool and Frigidaire. Kenmore, Bosch and Avanti also make built-in dishwashers in that size, as do Electrolux and Edgestar.
Each brand and model delivers a wide selection of features, making it important for buyers to find the right dishwasher to suit their needs. Shoppers should consider features that add convenience as well as dimensions that fit the available space in the kitchen, according to Consumer Reports. Those seeking to purchase a new 18-inch built-in dishwasher should also determine if they plan to regularly rinse dishes before running the dishwasher. Regular rinsing before loading can reduce or eliminate the need for a washer with a heavy-duty power-scrubbing mode.
Shoppers who value quiet operation should look for a dishwasher with a filter that requires manual cleaning, since self-cleaning options typically produce more noise. Adjustable racks that let you set the space between dishes can add a measure of convenience, as can silverware and stemware holders. Rinse and hold cycles are available on many models to allow users to rinse away grime and reduce odors from dishes that sit between loads, and delayed start settings deliver customized control over when the machine runs.
