LG Washing Machine: wiring damage
What is this symptom?
Experiencing wiring damage in your LG washing machine? This can manifest as visible frayed or melted wires, resulting in error codes, intermittent operation, or failure to start. Common culprits include worn wiring harnesses and insulation breakdown due to heat or vibration.
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
DIY Solutions
Inspect and secure wiring harness connections
- Disconnect power to the washer.
- Remove access panels to reach wiring harness (back or bottom as needed).
- Visually inspect harness, connectors, and insulation for damage or corrosion.
- Disconnect and re-seat connectors; clean any visible corrosion.
- Use a multimeter to check continuity on suspect wires.
- Reassemble panels and test machine.
- If minor insulation wear is found, wrap with electrical tape as a temporary mitigation.
Replace damaged wiring harness section
- Unplug machine and open to access the damaged harness.
- Identify damaged wire section.
- Cut out damaged portion and strip ends of remaining wires.
- Install new wires or harness section using proper connectors or soldering.
- Insulate joints with heat shrink or tape.
- Reassemble and test operation.

User Suggested Solutions
-
Inspect the wiring harness for damage. If chewed, cut out the damaged section and splice in new heat-proof wire using ceramic wire nuts or all-metal crimp connectors. Ensure all connections are secure and insulated properly.
-
Use rodent repellent sprays or traps around the washing machine area to prevent future infestations. Regularly check for signs of mice.
