LG Washing Machine dE Error Code Explained: Meaning, Causes & Fixes

 
Preliminary Safety Measures
 

• Disconnect the washing machine from the power outlet before attempting any repairs to ensure electrical safety.
• Turn off the water supply if you plan on inspecting internal components.
• Allow the machine to cool down if it was working recently.

 
Resetting the Washing Machine
 

• Disconnect the power for at least 10 minutes to allow the electronics to reset completely.
• After waiting, reconnect the power and observe if the error clears by running a short test cycle.
• If the error is still displayed, proceed to inspect the physical components of the door locking mechanism.

 
Inspecting the Door Lock and Latch Assembly
 

• Examine the door to ensure it is closing correctly, without any obstructions or misalignments.
• Visually inspect the door lock actuator and latch mechanism for signs of damage, misalignment, or wear.
• Clean any visible debris or residue from the door lock assembly that might interfere with proper engagement.
• Make sure that the door lock assemblies are securely in their housings, and there is no physical damage that might require replacement.

 
Checking Internal Wiring and Connections
 

• Remove the necessary panels to gain access to the wiring connected to the door lock assembly.
• Visually check all connectors and wiring harnesses for loose connections, corrosion, or signs of damage.
• Ensure that the wires leading to the door lock mechanism are firmly seated and free from fraying.
• If any connectors appear loose or damaged, gently reseat them or replace the faulty wiring as required.

 
Replacing Faulty Parts
 

• If the door lock assembly is found to be malfunctioning, order a genuine replacement part from LG or an authorized parts supplier.
• Follow the manufacturer’s instructions carefully when removing the defective door lock actuator or latch assembly.
• Install the new part securely, ensuring all wiring connections are properly reattached.
• Test the door mechanism manually to verify that it locks and releases correctly before reassembling the washing machine.

 
Verifying Control Board and Firmware Settings
 

• Inspect the control board for any visible signs of damage such as burnt components, corrosion, or loose solder joints.
• If your model supports firmware updates, check the LG website or user manual for any available updates that might address error code issues.
• In some cases, a control board reset or reinstallation may be required, which should be done by following the service manual instructions or by a qualified technician.

 
Performing a Diagnostic Test
 

• Consult the user manual for the procedure to run a built-in diagnostic or self-test cycle on your LG washing machine.
• Execute the diagnostic test to see if the error remains and to identify if any other components are affected.
• The results can guide further actions, such as additional repairs or part replacements.

 
When to Seek Professional Assistance
 

• If you have performed all troubleshooting steps and the dE error persists, it might indicate a deeper issue in the electronic control or wiring system.
• Contact an authorized LG service technician who can perform advanced diagnostics and repairs safely.
• A professional will have the appropriate tools and expertise to test the control board functionality and replace any non-serviceable components.
• Avoid further self-repair if you are not experienced with appliance electronics to prevent additional damage or safety hazards.
