What water temperature is needed for the best dishwashing results, and how do I check it?

Water entering the dishwasher should be at least 120°F (49°C) for satisfactory cleaning and drying results. To check the temperature, turn on the hot water faucet nearest the dishwasher for several minutes to clear cool water from the pipes, then hold a candy or meat thermometer in the water stream. If the temperature is below 120°F, have a qualified person raise the hot water heater thermostat setting. (Page 17)
