      Benjamin StoneAug 15, 2025
      If your LG Dishwasher displays the "OE" code, it means the water is not being pumped away. This could be due to a kinked drain hose or a clogged filter. Try straightening the hose or cleaning the filter to resolve the issue. If the problem persists, it may indicate motor trouble, and you should call for service.

      If your LG Dishwasher displays the "IE" code, it means that water is not being supplied. Ensure that the water tap is open and supplying water to the dishwasher. If the issue continues, it may be due to a water sensor problem, and you should call for service.

      If no lights come on when you turn on your LG Dishwasher, the plug may not be properly inserted into the socket. Check the plug to ensure it is correctly inserted. Also, check your home's fuses or circuit breaker, as blown fuses or a tripped breaker can cause this issue. In case of a power outage, call for service.

      If the LG Dishwasher displays a DRAIN ERROR because it hasn't fully drained after 5 minutes, start by cleaning the filter. Next, check the drain hose for any kinks or blockages and remove them. If the issue persists, the drain pump/motor or its circuit may be faulty, requiring replacement or repair.

      If you notice white deposits on your dishes after washing in your LG Dishwasher, it could be due to an incorrect amount of detergent or rinse-aid. Check the levels and adjust accordingly. It could also be caused by an empty salt container or a salt container cap that is not securely screwed on, so check these as well.

      If your LG Dishwasher displays the "EI" code, and the drain pump is automatically operating, it indicates a water leak from the hose connections or damage to the unit caused by a water leak. Close the water tap and unplug the power plug. Call for service.

    What to do if my LG Dishwasher displays a LEAKAGE ERROR?
    • T
      Toni AndersenSep 12, 2025
      If your LG Dishwasher displays a LEAKAGE ERROR because the water level in the tub goes down during operation, check the hose connections for water leakage and replace them if necessary. Inspect for any damages causing water leakage and repair or replace the affected parts. If the impeller of the washing pump is worn away, replace the washing pump. Also, check the applied voltage if the thermal protector of the washing motor is activated.
