What nE means (lg ne error)
An lg ne error on an LG dishwasher indicates a diverter (Vario) motor error — the motor that directs water between the upper and lower spray arms is not operating correctly. The control raises nE when it cannot confirm the diverter position, which affects how well each rack is washed.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your LG Dishwasher. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, or recent service.
- The display shows “nE”
- One rack washes poorly while the other is fine
- The spray pattern seems uneven between levels
- The fault recurs through the wash phase
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level check from a problem that needs trained service and the correct LG parts.
- Diverter motor fault — the Vario motor has failed
- Stuck diverter valve — debris jams the valve
- Wiring fault — the motor connection is broken
- Control fault — the board cannot read the diverter position
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where high-voltage parts, gas, the sealed refrigeration system, or a heat-pump compressor are involved, and hand the rest to a qualified technician.
- Power the dishwasher off at the breaker for several minutes, then restore.
- Clean the sump and filter in case debris is jamming the diverter.
- Note whether one rack consistently washes worse than the other.
- If nE persists, leave it for service to test the diverter motor.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the diverter (vario) motor, diverter valve, wiring, and control board. The correct part for your LG Dishwasher is matched from the model and serial number, and genuine LG components are fitted rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
nE needs a technician to test the diverter (Vario) motor and valve and replace the failed part. When the fix calls for trained service, book a visit through our scheduling page and an experienced, qualified technician will diagnose and repair it.

Prevention and care
Regular care keeps this condition from returning on your LG Dishwasher. Keep filters, vents, and the condenser or exhaust path clean, avoid overloading or blocking airflow, check that doors and seals close cleanly, and follow the LG maintenance guidance for your model. Because this unit relies on electronic control, protect it with a stable, correctly rated power supply and have any built-in or laundry installation done to LG specification so the control never sees an out-of-range condition. If a code appears, note exactly what was shown before you reset the appliance — that record helps the technician reach an accurate diagnosis and avoid replacing parts unnecessarily.
