Causes of the dE1 error code:

• Faulty door lock: 
  • The most common culprit is a malfunctioning door lock mechanism itself. It might be broken, have a faulty electrical connection, or be obstructed by a foreign object.
• Misaligned door: 
  • If the door isn't aligned correctly with the latch, it might not close securely and trigger the dE1 error. This can occur if the machine isn't level or if the door hinge is damaged.
• Damaged door seal: 
  • A torn or worn-out door seal can allow water to leak and prevent the door from closing properly.
• Door not closed firmly: 
  • While less likely, sometimes the door doesn't latch properly if it's not pushed shut firmly enough.

Troubleshooting the dE1 error code in LG Washing Machine

1. Turn off and unplug the washing machine.
2. Make sure the door is closed firmly. 
   • Push it shut until you hear a click or feel the latch engage.
3. Check for foreign objects: 
   • Look for anything stuck in the door opening or the latch that might prevent it from closing properly.
4. Level the washing machine: 
   • Uneven placement can throw the door alignment off. Use a spirit level to check and adjust the machine's legs if necessary.
5. Inspect the door seal: 
   • Look for tears, cracks, or other damage that could be preventing a secure seal.
6. Reset the washing machine: 
   • Disconnect the power cord for 30 seconds, then reconnect it and try restarting the cycle.
7. Consult the user manual or contact LG support: 
   • If the dE1 error persists after trying these steps, refer to your user manual for specific troubleshooting instructions or contact LG support for further assistance.

Here are some additional things to keep in mind:

• Never force the door open if the machine displays the dE1 error. This could damage the lock or hinge.
• If the door lock itself is the problem, you may need to call a qualified appliance repair technician to replace it.
• Regularly wipe down the door seal and hinge to prevent buildup and ensure proper closure.
