What does LG washer error code nC mean?

nC means the NFC (Near-Field Communication) module lost connection with the control board. Unplug the washer for 60 seconds and restart. The washer still runs cycles normally; only the NFC tap-to-connect feature is affected.

LG Washer Error Code nC — NFC Module Connection Fault

Easy Fix 5–15 minutes No tools needed

What this means

The nC error code indicates a connection failure between the Display PCB and the NFC PCB module. NFC is used by LG ThinQ-enabled washers for tap-to-connect functionality with smartphones. This error does not prevent the washer from running wash cycles but disables NFC pairing. It can be caused by a loose harness connection or a faulty NFC module.

Alternate codes: NC

Step-by-step fix

2 steps

Power-cycle the washer

Unplug the washer for 60 seconds, then plug it back in. This resets the NFC module communication.

Check for interference

Ensure no metallic objects or electronic devices are placed on or very near the NFC tag area on the washer (usually on the top panel).

When to call a professional

If the NFC feature is important to you and the code persists after a reset, a technician can check the NFC module wiring and replace the module if necessary.
