How do I refill the rinse aid dispenser?

Open the dishwasher door completely, remove the Fill Indicator cap, and add liquid rinse aid until it reaches the smallest opening in the lower part of the dispenser. The dispenser holds 6 oz (175 mL) and under normal conditions lasts about three months. Clean up any spilled rinse aid with a damp cloth and replace the cap tightly to prevent oversudsing. (Page 11)
