LG Dishwasher LE Error Code Explained: Meaning, Causes & Fixes

 
Understanding the LE Error Code on LG Dishwashers
 

The LE error code is an indicator that the dishwasher’s motor system has encountered an abnormal condition. In many LG dishwasher models, this error denotes that the control system has detected a deviation in the motor’s normal operating parameters. The error serves as a built‑in safety alert to prevent damage from prolonged operation under adverse conditions.

 
Detailed Explanation of the Error Code
 

• This error code is primarily associated with the motor or the circuitry that controls it. It signals that the motor does not behave as expected, such as not reaching the proper speed or failing to complete its rotation phases accurately.
• The system monitors motor rotation, sensor signals, and other diagnostic parameters during the wash cycle. When these readings stray from the pre‑defined limits, the LE code is activated.
• The protection mechanism aims to safeguard both the motor and the connected electronic circuits by stopping or limiting motor operation to avoid further complications.

 
Significance of the Error Code
 

The LE error code is not merely a random fault signal; it reflects an underlying issue within the motor’s operational circuitry. Its presence indicates that there is a discrepancy between the expected performance of the motor and what is actually being measured by the internal sensors. This discrepancy triggers the dishwasher’s control system to alert the user about the potential for motor overload or malfunction. The design of this error code is intended to isolate motor‑related issues, ensuring that any inconsistent behavior is highlighted promptly to prevent more extensive system damage.

 
Context of the LE Error Code
 

By displaying the LE error code, the dishwasher’s control board communicates that protective measures are in place and that the motor is not performing according to the manufacturer’s specifications. Understanding that this code specifically relates to motor operation helps in distinguishing it from other error codes that might point to issues with water supply, drainage, or other components. The LE code serves as a clear signal that something within the motor circuit is outside normal operational boundaries, providing crucial information for further technical evaluation.

 
Hardware and Sensor Failures
 

• One possible source of the LE error is a malfunction within the water detection sensor itself. Over time, buildup or corrosion in the sensor area can lead to false readings.
• Internal water leak sensors may trigger due to degradation of sensor components or accumulated residue that interferes with proper function.
• The float mechanism, if present, might become stuck or worn, causing the system to detect a leak even when none exists.

 
Wiring and Control Board Anomalies
 

• Damaged wiring, loose connections, or insulation breakdown in the sensor circuit can lead to irregular signals that result in the LE error code.
• Faulty solder joints or corrosion on the control board’s sensor interface might contribute to unintended leak alerts.
• Intermittent electrical shorts or surges can affect the sensor’s performance, indicating a leak condition even in the absence of actual water leakage.

 
Internal Component and Seal Issues
 

• Components such as door seals, gaskets, or water inlet valves may deteriorate over time. If these parts start allowing water to reach sensitive areas, the dishwasher can register a leak error.
• Installation-related issues where excess water collects around internal components can trigger sensor activation.
• Structural stresses or misalignment within the chassis might compromise waterproofing, leading to moisture in areas where it shouldn’t be, thus engaging the LE error.
