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

 
Preliminary Reset and Inspection
 

• Disconnect the washing machine from power by unplugging it from the outlet. Leave it unplugged for at least five minutes before reconnecting it. This reset procedure often clears temporary glitches that cause error displays.
• After reconnecting, observe whether the AE error persists. A complete power reset can sometimes clear minor electronic errors.
• Before proceeding further, check if the door is secured properly. Even though the door lock mechanism is not the direct focus here, ensuring proper door closure eliminates a potential source of interruption during the reset process.

 
Examine Wiring and Sensor Connections
 

• Remove the top or rear panel (as your model requires) to gain access to the internal wiring and sensor assemblies. Be sure to follow proper safety procedures; this means confirming the machine is unplugged and cleared for inspection.
• Inspect all visible connectors from the control board to the key sensors such as the water level sensor and temperature sensor. Ensure that the wiring harnesses are seated correctly and do not have any signs of damage or corrosion.
• If any loose or disconnected wires are found, re-seat them into their appropriate terminals. If damage is apparent, consider replacing the affected wires or the sensor unit as necessary.

 
Assess the Pump and Drain System
 

• Clear the pump filter of any lint, debris, or foreign objects that may impede the washing machine's drainage process. A compromised drain system can sometimes lead to error conditions that manifest as an AE error.
• Inspect the drain hose for any kinks or blockages. Gently straighten and, if possible, flush the hose with water to ensure it is free-flowing.
• Examine the pump assembly itself for obstructions; if the pump appears jammed or is malfunctioning, consult the service manual for in-depth guidance on cleaning or replacing it.

 
Update Firmware and Execute a Diagnostic Cycle
 

• Check if your washing machine model allows for a firmware update. Outdated firmware can sometimes trigger error codes if recent improvements or bug fixes address sensor or control board issues. Follow the manufacturer’s instructions for any firmware updates if available.
• If your model supports a diagnostic cycle or test mode, initiate it to help identify any hidden malfunction components. The diagnostic cycle is designed to stress-test the sensor responses and control signals. This process can help pinpoint if the error is recurring in a specific area or due to intermittent issues.
• Document any repeating error code readings during the test cycle. Such data can be useful for service personnel if the troubleshooting process requires professional intervention.

 
Finalize and Monitor the Repair Process
 

• Once all the components and interconnections have been inspected, cleaned, and re-secured, reassemble the machine securely.
• Reconnect the power and run a short cycle without any laundry. Observe closely whether the AE error recurs, paying attention to how the machine operates during different phases of its cycle.
• If the error does not reappear, gradually resume normal usage while continuing to monitor the machine for any signs of malfunction. If, however, the AE error returns, consider contacting a qualified repair technician for an in-depth evaluation of the washer’s control board and internal diagnostics.
