What is the recommended water heater temperature setting for best dishwasher performance?

A water heater setting of 120°F (49°C) is recommended for best performance. If the incoming water is cooler than this, the dishwasher will take longer to heat the water and cycle times will increase. Incoming water temperature should be at least 120°F (49°C) for proper sanitizing and cleaning results. (Pages 10, 11)
