A few years ago, the answer was that the dishwasher was better but a very careful hand-washer could probably use bout the same amount of water and less energy. However, much has changed since then. Technology combined with good design has made the dishwasher greatly better over the years, to the point where there’s hardly a question. Studies are showing that modern dishwashers can save more water than most hand-washers. Dishwashers are even more efficient. Modern dishwashers have pre-heaters that increase the water temperature up to 140 degrees Fahrenheit to sanitize them. The dishwasher also has a timer that lets you set it to turn on at a later time when the power rates are lower. On the other hand, none of the studies do an analysis of what it takes in terms of energy and water to actually build the dishwasher and replace it every 10 years or so. Nor does it take into account a Swedish study that found that children in families that wash dishes by hand are less likely to develop fever probably due to the “hygiene hypothesis”, which says the reason why kids fall ill is that their surroundings are actually too clean. If you’re not willing to fill up the sinks, the researchers point out that maybe the dishwasher is one labor-saving machine that does a better job than you can especially if you value your time. The researchers write, “When a user’s time spent washing dishes is valued, machine dishwashers pay for themselves within a year of use.” 1.
