How do I add rinse aid to the dishwasher?

Turn the dispenser cap counterclockwise and lift it off, then pour rinse aid into the opening until the indicator window looks full. Replace the dispenser cap and turn it clockwise to fully lock it. Add rinse aid when the indicator drops to the 'Refill' level, and for most water conditions the factory setting of 2 will give good results. (Page 4)
