LG Washer Error Code nF — Wi-Fi Module Hardware Problem
What this means
The nF error code indicates the washer's Wi-Fi module hardware is not functioning or cannot be detected by the main control board. Unlike nE (a connection issue), nF points to a hardware failure in the Wi-Fi module itself. The washer still operates normally for wash cycles; only LG ThinQ smart features are affected.
Alternate codes: NF
Step-by-step fix
2 stepsPower-cycle the washer
Unplug the washer for 60 seconds, then plug it back in. Attempt to reconnect via the LG ThinQ app.
Check the Wi-Fi module connection
Unplug the washer. Remove the top panel to access the Wi-Fi module (usually a small circuit board near the main control board). Disconnect and reseat the module connector.
When to call a professional
If the module needs replacement, a technician can install a new Wi-Fi module. The washer functions normally for washing without it.
