Lg Washer Error Code Se

LG Washer Error Code SE

A display of error code SE denotes a motor problem. While the error is displaying, the washer is non-functional despite that it continues to gain water in the tank.

Causes of the error code SE

  • Poor connections– there may be a connection problem between the motor and other components, such as the control unit causing interruption of the communication between them.
  • Faulty motor– this is the leading cause of code error SE. A defective motor will not rotate the shafts, and neither will the load drums. The washing cycle will not work. The central control unit detects the problem and notifies you with the error code SE.


Sometimes the error code may pop up as a result of either slight failure of the system. You, therefore, need to do a system reset in an attempt to clear the error code. To reset, you must disconnect the washer from power for around 15 seconds. Then reconnect the washer and start the washing cycle. If the error code is cleared, then your machine is in good condition. You, however, need to proceed in fixing the issue if the above reset does not help.

Fixing the error code SE

Failure of the system reset tells that there could be an issue of major concern either in the motor or the central control unit or even both. You will need to disassemble the washing machine to access the motor. Inspect all wiring connections to the motor and replace the faulty ones then test the washer to see if the error clears. If that fails, detach the motor from all attachments and test to know whether it’s faulty to replace it. If only the carbon brushes in the motor are damaged, have them replaced and fix the motor back. If the error persists, you may need to replace the central control unit, which is an expensive and sophisticated exercise calling for the need for service professionals.

Other possible causes of the error code SE include a burnt resistor, which takes power to the tachogenerator.

Replacing the impaired resistor and tachogenerator

You need to open the back of the washer and detach the belt from the motor shaft. Then open the screw bolts to disengage the motor from its housing. Proceed to separate the contacts of the Hall sensor and use the ohms meter to test the resistance of the part. The typical resistance should be 60 Ohms. Test also whether the voltage of the tachogenerator is 0.2V. If the tachogenerator and the resistor are faults, you need to repair them to revert the washer to its working condition.
