Only use branded rinse aid for the dishwasher. Never fill the
rinse aid dispenser with any other cleaning agent (e.g. dishwasher
detergent or liquid detergent). This could damage the device.
When to refill the rinse aid dispenser:

can judge the amount of rinse aid by the color of the optical
level indicator "D" next to the cover. If the dispenser is full, you

decreases, as shown below. Never allow the rinse aid to empty
below 1/4.
