What causes LG washer motor sensor error?

LG washers are known for their efficiency and smart features that make laundry day a breeze. However, like any electronic appliance, they can sometimes encounter errors that disrupt their normal operation. One of the common errors that LG washers may experience is the motor sensor error. This error code is triggered when there is a problem with the motor sensor, which is responsible for detecting the speed and direction of the washer's motor.

Determining the motor sensor error

When the motor sensor error occurs, you will usually see an error code on the display panel of your LG washer. The error code may vary depending on the specific model of your washer, but it is generally indicated by letters such as "LE" or "LE1". In addition to the error code, you may observe abnormal washer behavior, such as the washer not spinning or draining properly.

Possible causes of the motor sensor error

Several factors can lead to the motor sensor error in LG washers:

1. 1. Damaged or loose motor sensor: Physical damage to the motor sensor or loose wiring connections can prevent it from accurately detecting the motor's movements. This can result in the washer producing the motor sensor error.
2. 2. Faulty Hall sensor: The motor sensor in LG washers is typically a Hall sensor, which uses voltage variations to detect the motor's position and speed. If the Hall sensor becomes faulty, it may provide incorrect readings or fail to detect any motor movement, triggering the motor sensor error.
3. 3. Overloaded drum: Overloading the washer beyond its recommended capacity can strain the motor and cause irregular movements. This extra stress can lead to the motor sensor error.
4. 4. Malfunctioning control board: The control board in an LG washer serves as the brain of the appliance, coordinating all its functions. If the control board develops a fault or glitch, it may send incorrect signals to the motor sensor, resulting in the error.
5. 5. Power supply issues: In some cases, power supply problems like voltage fluctuations or electrical surges can interfere with the functioning of the motor sensor. This can lead to the error code being displayed on the washer.

Troubleshooting and resolving the motor sensor error

If you encounter a motor sensor error on your LG washer, there are a few troubleshooting steps you can take:

1. 1. Check for physical damage: Inspect the motor sensor for any signs of physical damage or loose connections. If you find any issues, consider replacing or repairing the sensor.
2. 2. Test the Hall sensor: Using a multimeter, test the Hall sensor to ensure it is producing accurate readings. If the readings are inconsistent or nonexistent, it is likely faulty and needs to be replaced.
3. 3. Remove excess load: If you have overloaded the washer, remove some items to reduce the strain on the motor. This might resolve the error if it was triggered by an overstressed motor.
4. 4. Reset the control board: Try resetting the control board by unplugging the washer from the power source for a few minutes, then plugging it back in. This can sometimes resolve glitches and restore normal functioning.
5. 5. Check the power supply: Ensure that the power supply to the washer is stable and free from voltage fluctuations. Consider using a surge protector or voltage stabilizer to protect the appliance.

If these troubleshooting steps do not resolve the motor sensor error, it is recommended to contact a professional LG technician or customer support for further assistance. They will have the expertise and tools required to diagnose and fix the issue.

In conclusion, the motor sensor error in LG washers can be caused by factors such as damaged or loose motor sensors, faulty Hall sensors, overloaded drums, malfunctioning control boards, or power supply issues. By identifying the potential causes and following the troubleshooting steps, you can often resolve the motor sensor error and get your LG washer back to its optimal performance.
