Best Energy-Efficient Dishwashers for Lower Utility Bills 2023

Are looking Energy-Efficient Dishwashers? In today’s world, where environmental consciousness is increasingly important, making choices that benefit our wallets and the planet is crucial. We can significantly impact our kitchens, particularly when cleaning our dishes. While many believe handwashing dishes is eco-friendly, the truth is quite the opposite. Energy-efficient dishwashers have emerged as the more environmentally conscious choice, offering benefits beyond saving time and effort.

Energy-Efficient Dishwashers Energy Star Dishwashers

Watch for the little blue Energy Star label when shopping for a new dishwasher. This label indicates that the model meets strict energy efficiency standards. Energy Star-certified dishwashers use, on average, 12% less energy and 30% less water compared to standard models. If you want the best energy savings, look for the Energy Star Most Efficient designation.

Opting for an Energy Star-certified dishwasher can reduce utility expenses while decreasing your carbon footprint. These dishwashers consume less than half the energy needed for handwashing dishes and can conserve more than 8,000 gallons of water yearly. Typically, the annual cost of operating an Energy Star-certified dishwasher amounts to approximately $35, and throughout its lifespan, it can save you approximately 3,870 gallons of water.

How Much Electricity Does A Dishwasher Use?

Dishwashers use electricity, typically from 1200 to 2400 watts, with the average dishwasher using around 1800 watts per cycle. The main electricity consumption comes from the control electronics and pump, while the water is often heated using the hot water line. To determine the cost of running a dishwasher, you need to know its wattage, cycle duration, and the cost of electricity per kilowatt-hour.

Investing in an energy-efficient dishwasher can minimize energy usage. Older dishwasher models may have different energy consumption levels, so consulting the machine’s manual is beneficial. Dishwashers consume a notable amount of energy, but their primary function is to generate heat. By being aware of their energy usage and selecting energy-efficient models, we can make informed choices to decrease our energy consumption and promote a more sustainable lifestyle.

How Much Water Does a Dishwasher Use?

Dishwashers vary in water usage depending on their age and energy efficiency. Older models can use 9 to 14 gallons of water per load, while newer Energy Star-rated dishwashers use less than 4 gallons. Handwashing dishes can consume up to 27 gallons per load. Water usage is crucial when evaluating a dishwasher’s environmental impact and energy consumption.


Using a dishwasher is generally more energy-efficient compared to handwashing dishes. Despite the initial perception that electrical appliances consume more energy, dishwashers are designed to be water-efficient, which in turn makes them more energy-efficient. Dishwashers heat water more efficiently than running a tap, resulting in reduced energy consumption. You can minimize greenhouse gas emissions by using a dishwasher efficiently, avoiding pre-rinsing, and running full loads on an eco-cycle. However, washing dishes may be more eco-friendly if you frequently run half-full loads or have an older, less energy-efficient dishwasher. The dishwasher is often cheaper than handwashing, as it uses less water.

Dishwasher energy-saving tips

To save energy while using your dishwasher, here are some practical tips:

Run full loads

Load your dishwasher fully before running a cycle. It ensures you get the most out of each wash and reduces water and energy waste.

Skip rinsing

Modern dishwashers don’t require pre-rinsing. Instead, remove food scraps and empty liquids from your dishes before loading them. It saves water and time.

Consider air-drying

Instead of using the heat-dry cycle on your dishwasher, opt for air-drying if available. It lets Mother Nature do the work and reduces energy consumption.

Properly load the dishwasher

Follow the manufacturer’s instructions for loading dishes to optimize water and energy use. Ensure proper water circulation for effective cleaning.

Wash full loads only

Avoid running your dishwasher for half-full loads. It’s more efficient to wait until you have a full load to reduce water and energy waste. Use the rinse and hold feature for partial loads to prevent food buildup.

Use energy-saving options

Check your dishwasher’s cycle options and choose the one that requires the least energy. Look for “eco” cycles designed to minimize water and energy consumption.

Lower water heater temperature

Most dishwashers have built-in heaters, allowing you to reduce your water heater thermostat to 120°F (around medium-low setting). It saves on water heating costs.

Avoid peak hours

If your energy provider has peak-hour pricing, use the delay feature on your dishwasher to run cycles during off-peak times. It will help to reduce your bills. 

Think about other energy guzzlers

Run your dishwasher at night during the summer to give your air conditioning unit a break. In winter, run it in the morning to help your heating unit. The dishwasher’s ambient heat can contribute to maintaining a comfortable temperature.

Consider upgrading to an energy-efficient model

Newer dishwashers meet higher water and energy efficiency standards. Upgrading to these models can save both resources and money in the long run.

Factors to Consider Before Buying an Energy-Efficient Dishwasher

Energy Star rating

Look for dishwashers with an Energy Star rating of 4 or 5 stars. It indicates high energy efficiency and potential savings on your energy bills.

Water usage

Opt for a dishwasher that uses two and a half gallons of water per cycle or less. Lower water consumption means reduced environmental impact and lower water bills.

Noise level

Consider the dishwasher’s noise level. Look for models with a noise level of 45 decibels or less to minimize disturbances in your home.


Think about the features that matter to you. For example, a third rack provides extra space for silverware, a quick wash cycle saves time, and a child lock ensures safety.
