LG Dishwasher: error code LE, burning smell, electrical sparks
What is this symptom?
If your LG dishwasher displays the LE error code along with a burning smell and electrical sparks, it's crucial to address the issue immediately. This alarming combination indicates potential motor system malfunctions, wiring problems, or control board faults. Ignoring these symptoms can lead to further damage or safety hazards.
Possible Causes
Motor system malfunction (motor overload, locked impeller or rotor)
How to Identify: LE error indicates the motor isn’t sensing normal rotation; motor may overheat, produce burning smell, or fail to run; impeller can be obstructed preventing rotation. Check if motor fails to spin freely by hand (power off.
Part: Wash pump motor / circulation pump
Wiring harness damage or loose electrical connections
How to Identify: Signs of frayed, burnt, loose wires behind toe kick panel or near motor; electrical sparks observed; burning smell centered near wiring areas.
Part: Internal dishwasher wiring harness / connections
Control board fault
How to Identify: Persistent LE error even after checking motor and wiring; visible burn marks or smell near control board; intermittent random faults.
Part: Main control board / PCB
Burnt solenoid on drain or valve components
How to Identify: Burn marks near solenoid connection, burning smell during drain cycle without full motor operation.
Part: Drain valve solenoid
