Are New Dishwashers More Energy-Efficient? Explained

The answer is yes, new dishwashers are more energy-efficient than older models, thanks to improved technology and stricter standards. A new dishwasher can save you money on your utility bills, water consumption, and detergent use, while also delivering better performance and convenience. In this article, we will explain how new dishwashers achieve higher efficiency, what to look for when buying a new dishwasher, and some tips to optimize your dishwasher usage.

How New Dishwashers Achieve Higher Efficiency

Dishwasher technology has improved dramatically over the last decade and new models include several innovations that reduce energy and water consumption and improve performance. According to ENERGY STAR, an ENERGY STAR certified dishwasher uses, on average, 12% less energy and 30% less water than a standard model. Here are some of the features that make new dishwashers more efficient:

  • Soil sensors: These sensors test how dirty the dishes are throughout the cycle and adjust the water temperature, pressure, and duration accordingly. This results in clean dishes with minimum water and energy use.
  • Improved water filtration: This feature removes food particles from the wash water, which allows for more efficient use of water and detergent during the cycle. It also reduces the need for pre-rinsing the dishes by hand, which can waste a lot of water.
  • More efficient jets: These jets spray detergent and water more accurately and evenly, covering more surface area and reaching hard-to-clean spots. This means less water and detergent are needed to achieve the same level of cleanliness.
  • Dish rack designs: These designs optimize the loading capacity and arrangement of the dishes, allowing for more dishes to be washed in one cycle and reducing the number of cycles needed. Some models also have adjustable racks, flatware slots, and third racks that offer more flexibility and convenience.
  • Drying methods: Some new dishwashers use alternative drying methods that are more energy-efficient than the traditional heated dry. For example, some models use air dry, condensation dry, fan-assisted dry, or mineral dry, which rely on natural evaporation, humidity, air circulation, or moisture-absorbing minerals to dry the dishes. Some models also have an automatic door release feature that opens the door slightly at the end of the cycle to let the steam out and the air in.

What to Look for When Buying a New Dishwasher

If you are in the market for a new dishwasher, there are some factors to consider to ensure you get the best energy-efficient model for your needs and budget. Here are some tips to help you choose the right dishwasher:

  • Look for the ENERGY STAR label: This label indicates that the model has met strict energy efficiency standards set by the Environmental Protection Agency (EPA) and the Department of Energy (DOE). An ENERGY STAR certified dishwasher will save you money on your utility bills and reduce your carbon footprint. You can also look for the ENERGY STAR Most Efficient designation, which identifies the best of the best in energy savings and innovation.
  • Check the EnergyGuide label: This label provides information about the estimated annual energy use, energy cost, and water use of the model, as well as the range of values for similar models. You can use this label to compare different models and find the most efficient one for your needs. You can also check the ENERGY STAR product finder to see the detailed specifications and ratings of different models.
  • Consider the size and capacity: It is important to think about the size and capacity of the dishwasher that will fit your kitchen and your household. Dishwashers come in two main types: standard and compact. Standard dishwashers are 24 inches wide and can hold up to 15 place settings, while compact dishwashers are 18 inches wide and can hold up to 8 place settings. Compact dishwashers are more suitable for small kitchens and households, but they may not be as efficient as standard dishwashers in terms of energy and water use per load. You should also consider the number of cycles and options that the dishwasher offers, as well as the noise level and the design and appearance of the dishwasher.
  • Read reviews and ratings: Before buying a new dishwasher, it is a good idea to read reviews and ratings from experts and consumers who have used the model. You can find reviews and ratings on websites like Consumer ReportsTom’s Guide, and [Amazon]. Reviews and ratings can give you an insight into the performance, quality, reliability, and customer satisfaction of the model, as well as the pros and cons and any potential issues or problems.

Tips to Optimize Your Dishwasher Usage

Once you have bought a new dishwasher, you can optimize your dishwasher usage to maximize its efficiency and save even more money and energy. Here are some simple tips to follow:

  • Only run full loads: Your dishwasher will use the same amount of water and energy each cycle, no matter how many dishes are inside. Therefore, you should wait until you have a full load before running the dishwasher, to make the most of the resources it uses. Loading the dishwasher properly can also help you fit more dishes in one cycle and improve the cleaning performance.
  • Skip the pre-rinse: Most dishwashers today are powerful enough to get all the gunk off, so pre-rinsing the dishes by hand is often unnecessary and wasteful. Instead, you should just scrape off the loose food from the dishes and load them in the dishwasher. If you have dishes that are very dirty or have dried-on food, you can soak them in water for a few minutes before loading them, or use the pre-wash or rinse cycle of the dishwasher if it has one.
  • Use the eco or energy-saving mode: Most dishwashers have an eco or energy-saving mode that uses less water and energy than the normal mode. This mode may take longer to complete, but it will save you money and reduce your environmental impact. You can also use the half-load or light-wash mode if you have fewer or less dirty dishes, or the delay-start or off-peak mode if you want to run the dishwasher at a time when electricity rates are lower.
  • Choose the right detergent and rinse aid: You should use a dishwasher detergent and rinse aid that are natural, biodegradable, and free of petroleum and phosphates, as these chemicals can harm the environment and your health. You should also use the recommended amount of detergent and rinse aid, as using too much or too little can affect the cleaning performance and the efficiency of the dishwasher. You can also use a natural residue eliminator like [Wave Jet] to prevent spotting and filming on your dishes.
  • Air dry instead of heat dry: Instead of letting your dishwasher use electric heat or a fan to dry the dishes, you can choose the air dry or no heat option if your dishwasher has one. This will save energy and prevent your dishes from getting warped or damaged by the heat. You can also open the door slightly at the end of the cycle to let the steam out and the air in, or leave the dishes to dry overnight.
