Temperature Requirements for Effective Dishwashing
To get your dishes clean, your dishwasher needs the right water temperature. Water should be up to 140 degrees Fahrenheit (60 degrees Celsius) during the main wash. This high heat breaks down tough food and grease well.
Optimal Water Temperature Settings
The dishwasher’s water temperature in the primary wash is between 130°F to 140°F (54°C to 60°C). But, it can go up to 180°F (82°C) in the rinse to sanitize dishes. Remember, water over 110°F (43°C) can be too hot for your hands.
Heat-Drying vs. Air-Drying Options
- Heat-drying uses more energy because it needs the dishwasher’s heating element to dry dishes.
- Opening the dishwasher door after washing to air-dry can save a lot of energy and money.
- Some dishwashers have special heating systems that are more energy-efficient than home water heaters.
To keep your dishwasher working well, clean it regularly. Use Finish® Dishwasher Cleaner once a month to remove limescale and food waste. This helps your dishwasher stay efficient.
Water Usage Comparison: Old vs. New Dishwashers
Modern dishwashers have made a big leap in saving water. Older models used up to 15 gallons per cycle. Now, ENERGY STAR-rated dishwashers use only 2.35 gallons per load.
Older dishwashers from before 1994 used 9 to 14 gallons per cycle. Today’s ENERGY STAR dishwashers use no more than 4 gallons. This is a huge water savings, up to 75% less than hand washing.
