What Does Error Code nE Mean on a LG Dishwasher?

Vario motor error — wash arm diverter motor not reaching position.

The vario diverter motor rotates a disc that routes pressurized water to either the upper or lower spray arm. When the control board commands a position change, it waits for the position microswitch to confirm the new setting. nE fires when that confirmation never arrives within the expected time. Debris lodged in the diverter disc is the leading cause, physically blocking rotation. This differs from LE (main wash-motor fault) and AE (leak/overflow), which involve separate circuits and sensors.

Models affected: LG dishwashers equipped with a vario/diverter motor that alternates water between upper and lower spray arms; commonly full-size models with dual-arm wash systems

What owners report: Owners commonly report nE appearing mid-cycle or shortly after a cycle starts, sometimes with poor wash performance on one rack. A quick clean of the sump and diverter area often clears it, so many find it is a false alarm from food debris rather than a failed motor.

What Causes Error Code nE?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

1

Debris jamming the diverter disc 40% of cases
2

Vario motor failed 30% of cases
3

Position microswitch fault 20% of cases
4

Harness or board fault 10% of cases

How to Fix LG Dishwasher Error Code nE

🔧🔧🔧 Advanced DIY Est. time: 1–3 hours

⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.

1

Clean the sump and diverter

Remove the lower rack, spray arm, and filter stack, then clear debris from the sump and around the diverter opening.
2

Test the vario motor

Disconnect power, access the motor under the tub, and check that its cam rotates in diagnostic mode or with bench power; replace if seized.

⚠️ Disconnect power at the breaker before tipping the unit or working underneath.
3

Check the position switch

If the motor turns but nE persists, the position microswitch on the assembly is misreporting — it usually comes with the motor assembly.

How to Reset Error Code nE

Power off at the breaker for 60 seconds after cleaning, then run a short cycle.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

Frequently Asked Questions

Can I keep using my LG Dishwasher when error nE appears? +

You often can for a cycle or two, but the motor issue behind nE will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.

What most commonly causes nE on a LG Dishwasher? +

Across reported LG dishwasher repairs, the most frequent is debris jamming the diverter disc (40% of cases), vario motor failed (30%), then position microswitch fault (20%). Check them in that order before replacing any parts.

nE keeps coming back after a reset — what should I check next? +

A reset only clears the stored nE fault; if it returns, the motor problem is still present. Move on to the physical checks — clean the sump and diverter, then test the vario motor — since the code will reappear until the root cause is resolved. This is an advanced repair involving deeper disassembly or electrical testing.

How much does it cost to fix LG Dishwasher error nE? +

A DIY repair typically runs $0–$70 in parts, versus $150–$290 for a professional service call, so handling it yourself saves around $150. Expect the work to take 1–3 hours.

Which LG Dishwasher models show error nE? +

nE is documented on LG dishwashers equipped with a vario/diverter motor that alternates water between upper and lower spray arms; commonly full-size models with dual-arm wash systems. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
