Important Tips for Lg Models

  • LG washers often report broken wires in the motor wiring harness leading to communication errors (e.g., LE error) and loss of operation

Possible Causes

Worn or broken wiring harness to motor or sensors

How to Identify: Visual inspection shows frayed, broken wires; machine displays communication error codes like LE or won’t start or run

Part: Motor wiring harness / position sensor wires

Insulation breakdown from vibration or heat over time

How to Identify: Insulation cracked or deteriorated on wiring upon inspection; possible short circuits or erratic behavior

Part: Internal wiring harness insulation

Corroded or loose connector contacts

How to Identify: Intermittent connections, operation returns when connectors reseated; visible corrosion at connector pins

Part: Connectors in wiring harness
