LG Washing Machine nC Error
Applies to front-load washers fitted with an NFC module, on LG's list. LG groups nC under its 'others' control codes with E80, nE, nF and PS; its resolution is the family's: a 60-second unplug reset, then service if the code persists.
What to check first
- Unplug the washer, wait a full 60 seconds, plug it back in and restart — LG's resolution for nC.
- Write the code down exactly before resetting: this family's codes are look-alikes.
- If nC persists after the reset, LG directs you to service.
nC is one of the connection codes in LG's control family: the Display PCB and the NFC PCB module — the board that handles the washer's tap-to-phone features — are not connecting properly. Like its siblings, it is a fault in the machine's nervous system rather than its plumbing or mechanics, and LG's published resolution is the family's one: unplug, wait 60 seconds, restart — service if it persists.
LG treats nC within the control family block at the end of its front-load list rather than as a standalone entry, and this page follows that guidance. The whole family is introduced on the control & connection family overview, and each code has its own guide linked below.
Safety first
- Board and wiring faults are not user-serviceable: the reset at the plug is the whole home procedure. Do not open the control panel or the machine's top cover to inspect boards.
- Stop condition: stop using the machine and unplug it — and do not run it again until it has been checked — if you smell burning, see smoke, find damaged electrics (a scorched plug, a melted or cut cable), or water is leaking in quantity.
Common causes
A faulty connection between the display board and the NFC module
LG's definition of nC is the fault itself: the connection between the Display PCB and the NFC PCB module is faulty. LG publishes no owner-level cause beyond the reset — the reset separates a transient upset from a connection or module fault, which is a service diagnosis either way.
Step-by-step checks
- Read the display twiceThese codes are look-alikes — and PS is literally misread as P5 on seven-segment displays, as LG notes. Write down exactly what is shown before resetting anything.
- Reset for 60 secondsUnplug the washer, wait a full 60 seconds, plug it back in and restart. This is LG's specified resolution for this code, as for the whole control family.
When to call a technician
If nC persists after the 60-second reset, LG's front-load list directs you to service. Quote nC exactly: it points the technician at the NFC link first, where E80 points at board-to-board communication, nE/nF at Wi-Fi, and PS at the supply.
Model differences that matter
| Machine type | What changes |
|---|---|
| Front load | The family is documented on LG's front-load list: E80, nC, nE, nF and PS, each with the 60-second reset and the service ending; PS adds the direct-to-wall-outlet rule. |
| Connected models | nC, nE and nF only exist where the hardware does — NFC and Wi-Fi modules. A washer with no connectivity cannot show them; E80 and PS are the members any front loader can produce. |
One-page checklist
- Exact code written down before resetting
- Washer unplugged for a full 60 seconds and restarted
- nC persists — service booked with nC quoted

Questions people ask about nC
What is NFC doing on a washing machine?
It is the tap-to-phone link some LG models carry — the NFC module is how the washer talks to a phone held against the panel for tag-on features. nC reports that the display board's connection to that module is faulty; the wash itself is not the fault.
My washer has no NFC. Can it show nC?
No — nC only exists where the hardware does. A washer with no NFC module cannot produce it; E80 and PS are the control-family members any front loader can show.
Why does LG give five codes one fix?
Because the home-level fix genuinely is the same — a full power-down reset — and everything beyond it is board-level diagnosis. The codes differ so the technician starts in the right place, not so the owner does five different repairs.
