Display shows rA; rinse aid indicator malfunction or calibration issue.

Safety note: This is typically a non-critical issue affecting only the indicator.

• Empty and refill dispenser: Use a turkey baster or syringe to remove rinse aid, then refill slowly to avoid air pockets.
• Run several cycles: The sensor may recalibrate after a few wash cycles.
• Inspect dispenser wiring: If the code persists, check the dispenser connector behind the inner door panel.
• Replace dispenser: Replace the dispenser assembly if the sensor remains inaccurate.
