What LE means (lg le error)
An lg le error on an LG dishwasher indicates a wash-motor error — the circulation motor that drives the spray arms is not running as commanded (some models show CE for a related condition). The control raises LE when it loses the expected motor response, which usually needs the motor or its control tested.
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 “LE”
- The spray arms do not turn and dishes stay dirty
- The wash motor hums, strains, or is silent
- 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.
- Wash motor fault — the circulation motor has failed or stalled
- Obstruction — debris or glass jams the impeller
- Motor control fault — the drive electronics misread or mis-drive
- Wiring fault — the motor connection is broken
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 off and check the sump and spray arms for debris or broken glass.
- Confirm the spray arms spin freely by hand.
- Power the dishwasher off at the breaker for several minutes, then retry.
- If LE returns, leave it for service to test the wash motor.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the wash (circulation) motor, motor control, 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
LE needs a technician to test the wash (circulation) motor and its control and clear any obstruction. 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. Where stored food, a sealed refrigerant system, gas, or a safety lockout is involved, treat the condition as a reason to act quickly rather than wait.
