LG Dishwasher UE Error Code Explained: Meaning, Causes & Fixes

 
Reset the Dishwasher
 

• Disconnect the dishwasher from power for at least one minute to allow the control board to reboot.
• Restore power and run an empty cycle to see if the error clears.

 
Check and Adjust Leveling
 

• Use a spirit level to verify that the dishwasher is perfectly horizontal.
• If the unit tilts toward one side, adjust the leveling feet accordingly by turning them until the dishwasher sits evenly on the floor.
• Recheck the level after adjustment, as an unlevel appliance can trigger the error during operation.

 
Inspect Door Latch and Seal Engagement
 

• Ensure that the door is closing firmly and that the latch is engaging properly.
• Check for any debris or damage around the door and the latch area which might prevent a secure closure.
• If the door does not align or latch correctly, inspect and replace the faulty components if necessary.

 
Examine the Rack Suspension and Internal Mountings
 

• Open the dishwasher and inspect the rack support system to ensure that all clips, rollers, and suspension parts are intact and properly seated.
• Look for any parts that might be loose or have shifted out of position, then secure or replace them as needed.
• A misaligned or damaged rack system can lead to imbalance during the cycle, triggering the error.

 
Perform a Deep Cleaning of Internal Components
 

• Remove and clean the filters, spray arms, and any debris from the interior.
• Ensure that ports and channels are unobstructed so that water can circulate normally during the wash cycle.
• A thorough cleaning can help restore proper operation if buildup has affected moving parts or sensors.

 
Reset and Test After Adjustments
 

• After performing the adjustments and cleaning, run a test cycle without dishes to monitor for recurrence of the error.
• If the error persists, repeat the checks or try another power cycle reset.
• Observe specific portions of the cycle to help narrow down if any particular operation still presents issues.

 
Seek Professional Service if Necessary
 

• If all the above steps have been conducted and the error remains, it might indicate a more complex issue with the control board or sensors.
• Contact a certified service technician to diagnose and repair any internal electronic or mechanical faults safely.
