Why is my dishwasher cycle taking so long?

Efficient dishwashers run longer to save water and energy, with typical cycle times of approximately 2.5 hours but varying based on selections. A water heater setting of 120°F (49°C) is best, as the dishwasher will delay longer while heating cooler water. Some options like Heat Dry add approximately 45 minutes to the cycle, and you can try the Quick Wash cycle for faster results.
