LG Error Code nE
Vario motor / spray arm issue
Common Causes
- 1Spray arm motor failure
Step-by-Step Troubleshooting
- 1
Remove the upper and lower spray arms and check for food debris blocking the spray holes — clogged holes can increase back-pressure on the vario motor
- 2
Clean the spray arm pivot bearings — remove each arm and flush the center mount with warm water to clear mineral deposits
- 3
Check that the spray arms spin freely when pushed by hand — any binding or grinding indicates worn bearings
- 4
The vario motor (diverter valve motor) directs water between upper and lower spray arms — listen for it switching during the cycle
- 5
Access the diverter valve under the tub sump and test the motor for continuity and freedom of rotation
Pro Diagnostic Tip
On LG TrueSteam dishwashers, the nE code can appear if the steam generator nozzle is blocked. The steam system shares a water diverter path with the spray arms. Check the steam nozzle for mineral scale before replacing the vario motor.
