What water temperature is required for effective cleaning in the GHD3800?
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 hot water into a glass from the faucet nearest the dishwasher until the temperature stops rising. (Page 12)
