How often should I fill the rinse aid dispenser?

The dispenser holds 5 oz (150 mL) of rinse aid, which under most conditions will last 1 to 3 months. To add rinse aid, open the rinse dispenser lid by gently pushing in the center with your thumb and pulling up on the edge, pour rinse aid into the opening until the dispenser is full without overfilling, and close the dispenser by pushing down gently on the lid.
