How do I adjust the water softener setting on my dishwasher?

Open the door, switch on the On/Off button, then hold down function key # and press the Start button until the display shows the water softener menu (•:0x). Release both buttons, then press function key 3 to select the desired setting based on your water hardness, and press the Start button to save. You can determine your water hardness using the test strip included with the dishwasher or by contacting your local water utility company.
