Quick answer
nF indicates a problem with the Wi-Fi module on LG front-load washers.
Model compatibility: LG reuses codes across series and model years, so nF may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
A problem with the Wi-Fi module.
nF means the Wi-Fi module on a front-load LG washer has a problem of its own, as opposed to a bad connection to it.
Try this first
Unplug the washer, let it sit for 60 seconds, then restart it. Request service when nF does not go away.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
