Energy-Efficient Dishwashers, Filters, and Safety
Dishwasher Features (continued)
Energy-Efficient Dishwashers.If you ever needed a justification for turning on a dishwasher, here's one: An energy-efficient dishwasher uses less human energy and less water than hand washing. (Just be sure the appliance is fully loaded before starting it up.) The latter is far easier to calculate than the former, but never mind.
All the dishwashers on our list except for the Frigidaire FBD2400K carry the Energy Star label.
Dishwasher Filters.Scraping and rinsing dishes before loading them into the dishwasher is supposed to be a thing of the past. If you plan on skipping this chore (but for big chunks of food), make sure the dishwasher comes equipped with a stainless steel food disposer to keep food from cycling back onto the dishes or clogging the pipes. The GE GDF520PGD and Maytag Jetclean Plus MDB4709PA satisfy this requirement.
A self-cleaning filter frees users from having to check and clean it, while a manual filter requires periodic cleaning. Perhaps counter-intuitively, many expensive European brands come with manual filters because they help reduce noise. Most cheap dishwashers, including those on our list, have self-cleaning filters.
