This post is the latest in the series “How long do appliances last?” They’re written in a style I learned in journalism, called “By The Numbers,” which was often just another way to say “I need to take up space and do something visual.” Voila.
The number of years in the average dishwasher’s lifespan, according to data published by Appliance Magazine in 2010. The life span reflects how long the first owner of a dishwasher owned it, which doesn’t necessarily mean that it broke down.
The number of cycles washed annually by the average dishwasher, according to the U.S. Department of Energy. That’s a little over four cycles per week.
How many gallons of water an Energy Star dishwasher uses per cycle.That’s 860 gallons annually.
How many gallons of water a standard dishwasher uses per cycle. That’s 1,290 gallons annually.
Up to this many gallons of water are wasted by well-meaning homeowners still stuck on pre-rinsing their dishes. Repeat after me: scrape, don’t rinse!
Average price of an Energy Star dishwasher, according to national retail data from 2009.
Average price of a standard dishwasher in 2009.
Amount of years it takes for the lower operations costs (assuming gas water heating) of an Energy Star dishwasher to make up, or “pay back,” for the initial sticker price difference.
Overall savings of an Energy Star dishwasher over its expected lifetime (assuming electric water heating).
