How should you run the dishwasher to save energy?

• A. Run the dishwasher only with a full load
• B. Run it every time
• C. Rinse dishes before loading
• D. Use the dishwasher with a partial load

Answer: (A)

Maximizing energy efficiency means running the dishwasher only when you have a full load. A cycle uses a fixed amount of energy to heat water and run pumps, so starting it with partial loads wastes energy because you’re paying the same energy price for cleaning fewer dishes. Waiting to run a full load cleans more dishes per cycle, making each use more economical in terms of energy. Modern dishwashers don’t require pre-rinsing and can be less efficient if you run them with small loads or every time anyway, so the best practice is to wait until the load is full before starting.
