What water temperature should I use for the dishwasher?
You should connect the dishwasher to a hot water supply with a temperature range between 120°F (49°C) and 149°F (65°C). This temperature range provides the best washing results and shortest cycle time, and the temperature should not exceed 149°F (65°C) to prevent damage to dishes. (Page 14)
