Function of the Rinse Aid Cap

The rinse aid cap covers the dispenser reservoir inside the dishwasher door. It prevents rinse aid from leaking out prematurely and ensures the correct amount is released during the rinse cycle. Without it, your dishes may dry poorly and come out with water spots or streaks.
