Dishwasher displays rA (lowercase r, uppercase A) and may not recognize rinse aid level correctly.

Safety First: Disconnect power before removing the inner door panel.

• 1. Confirm rinse aid level: Fill the rinse aid reservoir completely and ensure the cap is tightened properly.
• 2. Clean sensor port: Wipe around the dispenser opening and cap to remove any hardened residue that could block the sensor.
• 3. Inspect wiring: Access the back of the dispenser from inside the door and verify the harness connector is secure.
• 4. Replace dispenser: If the rA code remains, replace the Frigidaire dispenser assembly with integrated sensor.

If the issue persists after dispenser replacement, the main control board may be misinterpreting the sensor signal and should be checked by a technician.
