LG Dishwasher Error Codes
If your LG dishwasher displays an error code, it means the appliance has detected a problem during operation.
Modern LG dishwashers include built-in diagnostic systems that monitor components such as the water supply, drainage system, heating elements, sensors and motors. When the dishwasher detects a fault, it will stop the wash cycle and display an error code on the control panel.
Understanding what each LG dishwasher error code means can help you identify the issue quickly and determine whether it is something simple you can check yourself or if professional repair may be required.
Try This First (Quick Reset)
• Turn the dishwasher off at the mains
• Leave it for 2–3 minutes

This can clear temporary faults and save you an unnecessary repair.
