You can energy & money just on making some changes on how you run your dishwasher. New models use less energy and have more control options. Like the energy saver cycle use this button when every possible.
If your dishwasher has a booster heater you can save energy by turning your home water heater down to 120F. The booster heater option will raise the water temp at least 20F warmer. It will take a little longer for the water to heat up but unless you’re washing multiply loads back to back in the long run you will save energy.
Use the No-heat air dry button for your drying cycle. If the option isn’t available open the door after the rinse cycle and let it air dry. You may get spotting give it a try and see how it works with your system. If you have the time air drying takes longer so try running your system before work or bedtime.
Don’t pre rinse your dishes with warm water before your load your dishwasher. Scarp the food and give it a quick rinse with cold water. The dishwasher is designed to clean even heavily soiled plates. So why run the hot water twice to clean the same plate.
Try to fill the dishwasher with a full load. It’s going to use the same amount of water to clean one plate or a full load. Half loads are just a waste of energy, do you best to reduce water and energy.
