LG Washer Error Code nF: How to Fix It

Q: What does error nF mean on an LG washer?

nF stands for 'No Fill'. The washer detects that water is not entering the drum properly, even though the cycle may have started.

Q: How do I reset my LG washer after error nF?

Unplug the washer for 1 minute, then plug it back in and select a new cycle. If the issue persists, the underlying problem (e.g., clogged filter or faulty valve) must be fixed.

Q: Can a kinked hose cause error nF?

Yes, a severely kinked or bent water inlet hose can prevent water flow, triggering the nF error. Straighten or replace the hose as needed.

Q: Do I need to replace the water inlet valve for error nF?

If the valve fails to open (no clicking sound) or has no continuity, replacement is necessary. Clean the filters first – they are often the culprit.

Q: Why does my LG washer fill slowly before showing nF?

Slow filling indicates a partial restriction, commonly a dirty inlet filter or low water pressure. Clean the filters and check water pressure to prevent the error.

Abstract

The LG washer error code nF means 'no fill detected' – the washer's control board isn't sensing water entering the drum. This typically happens due to a closed water supply, a clogged inlet filter, or a faulty water inlet valve. Follow these steps to diagnose and fix the issue safely.
