If the rinse aid dosage level has been set to ZERO (ECO) in the Dishwasher's settings, the LOW RINSE AID indicator light will not illuminate even if the rinse aid dispenser runs empty. This is expected behavior for this specific setting.
Click steps to track your progress.
Verify your current rinse aid dosage setting by following the 'Adjusting the Dosage of Rinse Aid' steps in the manual.
If you wish for the indicator light to function and to use rinse aid, set the dosage to a level other than ZERO (ECO).
If using the ECO setting, visually check the rinse aid level periodically to ensure it does not run out.
