Pour the rinse aid into the dispenser, being careful not to overfill.
Replace the cap by inserting it aligned with "open" arrow and turning it to the "closed" (right)
arrow.
The rinse aid is released during the final rinse to prevent water from forming droplets on your
dishes that can leave spots and streaks. It also improves drying by allowing water to sheet
off the dishes. Your dishwashers are designed to use liquid rinse aids. The rinse aid dispenser
is located inside the door next to the detergent dispenser.
To fill the dispenser, open the cap and pour the rinse aid into the dispenser until the level
indicator turns completely black. The volume of the rinse aid container is about 140ml.
Be careful not to overfill the dispenser, as this could cause excessive foaming. Wipe away
any spills with a damp cloth. Don't forget to replace the cap before you close dishwasher
door.
Note:
Clean up any rinse aid split during filling with an absorbent cloth to
avoid excess foaming during the next wash.
