Display shows Cd at the end of the cycle; fan may continue running.

This is typically not an error code but an indication that the dishwasher is in a cool-down or drying phase.

• Allow completion: Let the dishwasher finish the cool-down period. The display should clear on its own.
• Disable extra dry (if desired): If you prefer shorter cycles, turn off any Extra Dry or Night Dry options in the settings.
• Power reset: If Cd remains stuck for an unusually long time, turn off the breaker for 1 minute, then restore power.

No parts typically need replacement for Cd unless accompanied by other error codes or abnormal behavior.
