What brand dishwasher to avoid?

The dishwasher brands to avoid or approach with caution based on Yale Appliance service data, Consumer Reports predicted reliability, and technician surveys are those with high first-year service call rates and expensive parts. Brands with higher service rates include some budget Frigidaire and Beko models that have service call rates of 15 to 20 percent, well above industry average of 10 to 12 percent, with complaints of poor cleaning, leaking, and control board failures. Some Samsung dishwasher models have had higher service rates of 12 to 15 percent due to control board and leak sensor issues, though newer models have improved. Certain budget Chinese brands sold online with no US service network should be avoided because parts are unavailable and warranty service is difficult. However, no major brand is universally bad, reliability varies by model. Brands with best reliability include Bosch, Miele, and KitchenAid/Whirlpool with service rates of 7 to 10 percent. Bosch 300 and 500 series like SHEM63W55N are consistently top rated for quietness and cleaning. To avoid problems, avoid cheapest models under 400 dollars that use plastic tubs and have poor insulation, avoid models with no filter access, and check specific model reviews rather than just brand, as even reliable brands have occasional problematic models. Look for stainless steel tub, third rack, and good warranty.
