LG Dishwasher NE Error Code: NFC Tag Error

NE appears on LG dishwashers equipped with SmartThinQ NFC functionality. The NFC tag embedded in the appliance is used for app pairing and service identification. NE means the control board's NFC reader circuit got a failed or incomplete read response. In nearly all reported cases, this is a transient error that clears by itself after a power cycle. It does not affect wash performance. If NE appears repeatedly, the NFC antenna module or its connection to the main board may need inspection.

Is NE only on certain LG dishwasher models?
Yes. NE appears only on LG dishwashers with SmartThinQ NFC capability. Older LG models without this feature will not display NE.
