What water temperature does the GSD1120 require for good washing results?
The entering water must be between 120°F and 140°F for good washing and drying. To prevent dish damage, inlet water should not exceed 150°F. If your water temperature is below 140°F, you should select the WASH HEAT BOOST option, which extends the wash cycle by 21 minutes while the dishwasher heats the water. (Page 6)
