How do I fill and adjust the rinse aid dispenser?

Open the rinse aid dispenser lid by pushing in the center with your thumb and pulling up on the edge, then pour rinse aid in until full — the dispenser holds 5 oz (150 mL) and typically lasts 1 to 3 months. Clean up any spills immediately, as spilled rinse aid can cause excessive suds. You can adjust the amount dispensed by turning the arrow adjuster to a higher number for more rinse aid or a lower number for less; change only one number at a time and run a few cycles before adjusting again.
