How do I add and adjust rinse aid in my dishwasher?

Turn the dispenser cap counterclockwise and lift it off, then pour rinse aid into the opening until the indicator window looks full; replace and lock the cap by turning it clockwise. Add rinse aid when the indicator drops to the 'Refill' level. For most water conditions, the factory setting of 2 gives good results, but you can adjust the arrow adjuster inside the dispenser with your fingers or a flat-blade screwdriver if you have hard water or notice spots.
