Simple Tips for a More Energy-Efficient Dishwasher

In today’s world, where environmental concerns are at the forefront of many conversations, finding ways to reduce our carbon footprint has become increasingly important.

One often-overlooked area where we can make a significant difference is in our own homes, particularly with the appliances we use on a daily basis. The dishwasher, a staple in many households, is a prime candidate for energy efficiency improvements. By implementing some simple yet effective tips, you can not only save money on your utility bills but also contribute to a greener planet.

Choose an Energy-Efficient Dishwasher

When it comes to purchasing a new dishwasher, not all models are created equal in terms of energy efficiency. One of the easiest ways to ensure you’re making an environmentally friendly choice is to look for the ENERGY STAR label. ENERGY STAR-rated appliances meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE). These dishwashers typically use less water and energy compared to non-certified models, saving you money in the long run while reducing your carbon footprint.

Additionally, consider the size and capacity of the dishwasher. Opting for a model that can accommodate larger loads means you’ll be able to run fewer cycles overall, saving both water and energy. Look for features such as adjustable racks and fold-down tines that allow for flexible loading configurations, ensuring you can make the most of each wash cycle.

Run Full Loads

One of the simplest ways to maximize the energy efficiency of your dishwasher is to wait until it’s fully loaded before running a cycle. Running partial loads wastes both water and energy since the dishwasher uses the same amount of resources regardless of the load size. Encourage your household members to scrape excess food off their dishes rather than rinsing them before placing them in the dishwasher. Not only does this save water, but it also helps preserve the dishwasher’s energy efficiency by reducing the need for additional rinsing cycles.

Consider investing in a dishwasher with a load sensor feature, which adjusts the water and energy usage based on the size of the load. This ensures that even smaller loads are washed efficiently, without wasting resources. Additionally, if you have the option, try to schedule your dishwasher to run during off-peak hours when electricity demand is lower, potentially reducing your energy costs even further.

Scrape, Don’t Pre-Rinse

Contrary to popular belief, pre-rinsing your dishes before loading them into the dishwasher is not only unnecessary but also wasteful. Most modern dishwashers are designed to effectively remove food particles from dishes, even without pre-rinsing. Instead of rinsing your dishes under running water, simply scrape off any large food scraps into the trash or compost bin. This not only conserves water but also saves time and energy.

If you’re concerned about stubborn food residue, consider using a biodegradable dishwasher detergent with enzymes that help break down food particles during the wash cycle. Additionally, regularly cleaning the dishwasher’s filter and spray arms can help ensure optimal performance, reducing the need for pre-rinsing in the first place. By adopting this simple habit, you can significantly reduce your water consumption and contribute to a more sustainable household routine.

Use the Energy-Saving Mode

Many dishwashers come equipped with an energy-saving mode or eco-cycle, specifically designed to reduce water and energy consumption during the wash cycle. This mode typically extends the duration of the cycle but uses lower temperatures and less water, resulting in significant energy savings. Before starting a wash cycle, check if your dishwasher has an energy-saving mode and make it your default setting for everyday use.

In addition to using the energy-saving mode, consider loading your dishwasher strategically to maximize its efficiency. Place heavily soiled dishes near the spray arms for thorough cleaning and arrange delicate items on the top rack to avoid damage from the water jets. By optimizing your dishwasher’s settings and load configuration, you can minimize energy waste while still achieving sparkling clean results.

Optimize Water Temperature

The temperature of the water used in your dishwasher can have a significant impact on its energy efficiency. While hot water is necessary for effective cleaning, excessively high temperatures can waste energy and increase your utility bills. Most dishwashers have adjustable water temperature settings, allowing you to customize the wash cycle based on your needs.

For everyday loads with lightly soiled dishes, opt for lower water temperatures to conserve energy. Reserve higher temperatures for heavily soiled or sanitizing cycles, where the extra heat is necessary for thorough cleaning. Additionally, consider installing a water heater with adjustable temperature settings to ensure that your dishwasher receives water at the optimal temperature for energy efficiency.

Air Dry Instead of Heat Dry

Many dishwashers offer the option to air dry dishes instead of using heat drying, which can consume a significant amount of energy. By allowing dishes to air dry naturally, you not only save energy but also avoid the risk of heat damage to delicate items. Simply select the air-dry setting or open the dishwasher door at the end of the cycle to let the dishes dry without additional energy consumption.

To enhance the effectiveness of air drying, use a rinse aid to reduce water spots and promote faster drying. Additionally, consider investing in dishwasher-safe drying racks or mats to provide extra space for dishes to air dry effectively. By making air drying a regular part of your dishwashing routine, you can minimize energy usage and enjoy the benefits of lower utility bills.

Maintain Your Dishwasher

Regular maintenance is essential for ensuring the long-term energy efficiency of your dishwasher. Clean the filter regularly to prevent clogs and ensure optimal water flow during the wash cycle. Check the door seals for signs of wear or damage and replace them if necessary to prevent leaks that can waste water and energy.

In addition to routine maintenance, be mindful of how you load the dishwasher to prevent overcrowding and ensure proper water circulation. Avoid blocking the spray arms or overloading the racks, as this can interfere with the cleaning process and reduce efficiency. By taking proactive steps to maintain your dishwasher, you can prolong its lifespan and maximize its energy-saving potential.


In conclusion, achieving a more energy-efficient dishwasher is within reach for every household. By following these simple tips, you can minimize water and energy consumption while still enjoying the convenience of modern dishwashing technology. From choosing an energy-efficient dishwasher to adopting eco-friendly habits like running full loads and air drying dishes, every small change adds up to significant savings over time. Together, we can make a positive impact on the environment and create a more sustainable future for generations to come.
