      Craig MatthewsAug 17, 2025
      If your LG Dishwasher shows the 'OE' error, it means there's a drainage problem. You should check the water drain hose for clogs, kinks, or freezing. Also, inspect the air gap or garbage disposal for any blockages and clean them if necessary. Finally, make sure to clean the filters, as clogged filters can also cause this error.
