The dishwasher has become a popular item in the kitchen — especially with teenagers who can escape clean-up duty.
Instead of elbow grease it uses electrical energy and a good deal more hot water. The energy consumed by the washer itself (not including hot water) amounts to about 300 kilowatt hours per year depending on how it's used.
Here are some ways to economize:
• Wash only full loads. Your dishwasher is most economical at full capacity. Don't use it for a few plates and forks. Save them up (rinse if necessary) and do a full load at the end of the day.
• Correct loading. Follow your manufacturer's recommendations for loading and use of detergent. It will run more efficiently and your dishes will be cleaner.
• Scrape dirty dishes. Pre-scraped dishes can be washed on a shorter cycle. And you don't have to worry about food particles hurting the machine's performance.
• Let dishes air dry. The dishwasher has a heater element to dry the dishes after the wash is completed. Stop the cycle before the element comes on and open the door. The hot dishes will dry themselves and you'll save some electricity.
• Don't warm plates in dishwasher. Some people use the heater element of the dishwasher to warm dinner plates for serving. Use the oven's heat instead.
