How do I fill and maintain the rinse aid dispenser?

The rinse aid dispenser holds 6 ounces (175 mL) and will last about 3 months under normal conditions. Check the fill indicator cap—if it's clear or shows an 'E', it needs filling. Fill to the smallest opening in the lower part of the dispenser without overfilling. Clean any spilled rinse aid with a damp cloth. (Page 13)
