      If you see the DOOR OPEN ERROR on your LG Washer, and you're using the reservation function, or another function, start by closing the door. This should resolve the error. If that doesn't work, it could indicate that the door switch is malfunctioning.

    • S
      Sara BrooksAug 31, 2025
      If your LG Washer displays a DRY HEATOR ERROR, the Dry Heater might be out of order and needs replacement. It could also mean that the connector of the Dry Heater isn't properly connected to the connector in the Main PWB ASSEMBLY; try reconnecting or repairing the connector. Another possibility is that the Dry fan motor is faulty and needs replacement.
