Having any dishwasher in your kitchen will save you time and energy in the long run, but if you want to truly minimize your energy use, there are many energy efficient models on the market. By using state-of-the-art motors, internal heaters, condenser drying technology, and other innovations, these dishwashers can save you even more on your power bill. Here's our list of five of the most energy efficient dishwashers of 2021. At 24 in. wide, they'll each fit into a standard cutout.
The DWHD650WFP is part of Thermador's Emerald series, bringing professional efficiency and high-end features into the home. From its dedicated chef's tool drawer to its fully adjustable upper rack, you can customize its interior for whatever you need to clean (and it can hold up to 16 place settings). It even has a dedicated Extra-Tall-Item™ sprinkler to make sure that water gets everywhere it needs to go. You can use the free Home Connect app to control and monitor this dishwasher from anywhere. Loading and unloading this dishwasher is also easy thanks to the Bleu LED internal light display (a Thermador hallmark) that elegantly illuminates even glassware whenever you open the door. All the water used by this dishwasher is filtered three times, meaning it needs less water than a regular dishwasher while still giving you a powerful cleaning experience. With an Impressively Quiet® design, it runs relatively silently, warranting Thermador's Blue PowerBeam® light indicator so you know when your unit is operating.
The GE GDF630PSMSS is both energy-efficient and budget-friendly, and it can handle up to 16 place settings in a single load. It has a variety of premium features such as four bottle-wash jets designed to clean even the tallest items, a steam prewash that loosens food residue, and a Piranha™ hard food disposer that spins at 3600 RPM and makes quick work of any caked-on residue. Each zone of its three-level 600-series wash System has its own set of pressure controls, so each jet is equally powerful. You can even optimize your efficiency on smaller loads by running the jets for only the top or bottom half. Its LED console display shows you at a glance the amount of time until the cycle ends, but if you choose the 60-minute cycle you won't have too much opportunity to check it. For the times you need even more power in a hurry, Dry Boost™ gets hard-to-dry items up to three times drier than a standard dry cycle.
LG's LDF5678SS is one of the smartest options on this list: you can use its WiFi Connect™ and SmartThinQ® technology to connect it to Google Assistant or Amazon Alexa and control it from anywhere in your house using only your voice. It even comes with SmartDiagnosis™ systems that can notify you on your smartphone when errors happen, which could save you both time and an expensive expense service call. It's not just the software that makes this dishwasher a smart choice, though: it can wash up to 15 place settings at a time, and its four QuadWash™ sprayer arms use Multi-Motion technology to spin back and forth during the cycle. This means your dishes are cleaned from every angle. Its SenseClean™ wash sensor and soil sensors reduce power and water usage by using only what is needed for each load, but the 3-stage filtration system and anti-bacterial treatment mean that you won't be skimping on clean.
Part of Viking's 5 Series, the VDWU324SS is a lovely, modern fully integrated dishwasher. Its LCD control panel lets you choose between the six wash cycles as easily as checking your text messages, while its three layers of QuietClean™ Performance insulation make it one of the quietest dishwashers available. Its heavy-gauge dish baskets can hold up to 14 place settings, but the tines can fold down to accommodate irregular loads as well, and even the cutlery basket can be moved to any position in the lower rack. The multi-level Power Wash function adjusts the water pressure and temperature based on soil levels and size of the dishes, so you don't use any more power or water than you have to, meaning that even the Quick Wash function will get your dishes fully clean in 35 minutes.
The Miele G4228SCU can hold up to 16 place settings, and it has many of the professional-grade features we've come to expect from the Classic series. Its simple full console controls include a bright, easy-to-read countdown indicator (which is handy because of the AutoSensor technology that dynamically adjust each cycle based on soil level) and five wash cycles that can handle anything from pots and pans to delicate stemware. The CleanAir™ drying system makes this dishwasher even more efficient: after each cycle, small fans draw room temperature air in through a port at the bottom of the appliance. This makes drying faster and quieter, without compromising on hygiene. You can save even more energy by connecting it to a hot water supply, which can reduce power consumption by 50% and even speed the cycle significantly. This dishwasher's Economy program also can reduce your energy consumption to 0.45 kWh.
What makes a dishwasher energy efficient?
Many modern dishwashers use a variety of sensor technology to limit the amount of resources they use. They can also reduce power and water consumption by including an energy saver cycle.
How do I know if my dishwasher is energy efficient?
The easiest way to check this is to see if your dishwasher is Energy Star-certified. (This includes all the appliances mentioned in this post.) These appliances use at least 12 percent less electricity than the average dishwasher unit, and up to 30 percent less water.
