How do I properly fill the rinse agent dispenser?

Unscrew the dispenser cap and add liquid rinse agent until it just reaches the bottom of the lip inside the dispenser opening, then replace the cap. The dispenser holds 4.5 ounces and should last about 3 months. If you accidentally spill rinse agent, wipe it up immediately with a damp cloth, as it can prevent your detergent from working. (Page 6)
