How do I adjust the rinse aid amount dispensed per cycle?

Press the On/Off button, then hold the function key and press Start until the display shows the settings menu, and press the function key until the display shows the rinse aid setting (factory default is level 5 of 6). Press the function key to select your desired level, then press Start to save. You should lower the setting if streaks remain on dishes, or increase it if dishes are not drying enough. (Page 14)
