What water temperature is required for effective cleaning in the GSD3715?
The entering water must be at least 120°F and not more than 150°F for effective cleaning and to prevent dish damage. You can check the water temperature using a candy or meat thermometer by running the hot water faucet nearest the dishwasher into a glass until the temperature stops rising.
