What should I do when my dishwasher displays the rinse aid indicator?

Last Update date : Feb 01. 2022

If the Rinse aid (rinse refill) indicator is lit, it means the dishwasher is low on dishwasher rinse aid and requires a refill. See the detailed instructions below.

When the Rinse Refill indicator lights up on the control panel, refill the machine with rinse aid. The rinse aid improves the drying performance of the dishwasher. The liquid rinse is automatically added during rinsing, allowing for a clean wash without streaking.

Dispenser location

The rinse container is located inside the dishwasher door. (It may differ between the models.)

The amount of rinse used for washing can be set by adjusting the dials 1 to 6 on the rinse cap. (More detergent is used as you proceed to 6.)

Step 4. For a better cleaning result, especially if you have very dirt items, add a small amount (about 8 g) of detergent on the door. That will act in the prewash phase.

Step 4. Set the rinse aid indicator dial to a number between 1 and 6. The larger the number is, the larger the amount of rinse aid that will be dispensed.

Step 5. Replace the cover. 

How to check the amount of rinse

  • You can check the amount of rinse aid by the color of the optical level indicator located next to the cap.
  • When the rinse-aid container is full, the whole indicator will be dark.
  • As the rinse aid diminishes, the size of the dark dot decreases. The rinse aid should be kept above 1/4 full.

Note: If there is no adjustable lever, please refer to the instructions in the user manual.

Rinse aid level setting

You can change the amount of rinse aid applied during a cycle.

Step 1. Press the Sanitize button to select the rinse aid level setting menu. The display shows the current setting. (Default setting is d4)

Step 2. Press the AUTO cycle button to change the setting. You can select from d1 to d5 (minimum to maximum).

Step 3. Wait 5 seconds to save the setting. 


  • Samsung dishwashers are designed to use liquid rinse aid only.
  • All dishwasher cycles require detergent in the detergent compartment. Add the correct amount of detergent for the selected cycle to ensure the best performance.
  • Use dishwasher detergent only. Regular detergent produces too much foam, which may decrease the dishwasher’s performance or cause it to malfunction.
  • Add rinse before the rinse aid leaves below 1/4.
  • If the rinse dispenser cap is hard to open, use a coin.
  • Keep dishwasher detergent out of the reach of children.
