Many Frigidaire dishwashers have a control panel with keypads for different cycle selections and various lights that illuminate or go out depending on the cycle status or any problems that may have occurred with the dishwasher. One such light is the "Rinse Low" light, which indicates that the rinse aid dispenser is low. Troubleshooting and resolving this issue is important in maintaining proper dishwasher rinse performance.
Open the Frigidaire dishwasher door after letting the washer finish the current cycle, if in operation. Find the rinse aid dispenser on the inside of the dishwasher door.
Turn the rinse aid dispenser cap a quarter turn counterclockwise direction and lift off the cap.
Pour in rinse aid until the liquid is visible and meets the "Fill Level" line. Close the cap on the dispenser and turn it clockwise to secure.
Wipe up any rinse aid that may have spilled. The "Rinse Low" light will go out when a new wash cycle is selected.
