How do I fill and adjust the rinse aid dispenser?

Turn the dispenser knob to 'Open,' lift it out, and pour liquid rinse aid into the opening until the indicator points to 'Full,' being careful not to overfill. The dispenser holds 5 oz (150 mL) and typically lasts 1 to 3 months under normal conditions. To adjust the amount released, remove the knob and turn the arrow adjuster inside the dispenser — the factory default setting of 2 works for most water conditions. (Page 12)
