LG washers come equipped with automatic error-monitoring systems that display error codes to help you troubleshoot problems, and sometimes fix them without the help of a service technician. They can also indicate a more serious problem that does require professional help.

Front-Loading Machines

A DE error code refers to an issue with the door. They could indicate a glitch during the middle or end of a cycle for no specific reason, an item stuck between the door and the gasket, or a damaged gasket. If this occurs, simply unplug the washer from the power outlet, wait 5 minutes and then plug the cord back into the outlet. Press the Power button -- the one to the left of the load selector dial -- and listen for the door lock to release. If it fails to release, unplug the unit and wait 30 minutes to reset it. If it fails to reset, contact a service tech.

An LE error indicates a general load error. This is an issue with the detergent -- too many suds -- or overloading the machine with too many items, especially for the Delicates, Hand-Wash, Perm-Press, Gentle or Wool-Silk cycles. Look through the door window. If you see suds, chances are this caused the LE error. High-efficiency (HE) machines use less water and a special detergent that doesn't create the suds typical of top-loading machines.

To fix this problem, unplug the machine from its power source. Set a timer for 30 minutes to give the suds enough time to dissipate. After the timer sounds, plug in the machine, push the Spin-Speed button, and then select the No Spin option. After that press the Start-Pause button so the machine begins draining. Once the drain cycle is complete, remove the clothing from the washer. Finally, turn on the machine, press Rinse & Spin, then press Start-Pause; repeat this step as needed until there are no suds in the washer's drum.

When your machine displays an OE code, it is an indication of some kind of pump, drain or water issue with the machine. When the washer isn't level, water that was supposed to drain can flow back into the machine. Fix the problem by adjusting the washer's feet with a wrench, checking your progress with a level placed atop the machine. Check and clean the pump filter, following your owners manual. Verify the drain hose is not crimped and the drain flows freely.

Unbalanced loads generate a UE error. Select the SpinSense option to allow the machine to sense and fix unbalanced errors sooner. This sensor can sense a load that might cause this error and uses an algorithm to make minor adjustments or corrections in spin speed to avoid excessive vibrations. Use this option when washing loads of jeans or bulky bedding items.

Top-Loading Machines

While top-loading machines have door error and unbalanced load codes, most of the other codes indicate a problem that a service technician must resolve.

An IE code indicates a water-inlet flow problem. Confirm that the water supply faucets are fully open. Check for fill hose kinks, low pressure or dirty screens in the inlet holes. The water inlet mechanism can also be malfunctioning.

A DE code indicates a door issue. The lid may be up, or, if the lid is down, the lid lock switch may be faulty or have a loose connection. Unplug the machine, and confirm that the wiring harness on the switch is properly connected; if so, replace the lid lock switch.

When the DL code alights, the lock mechanism cannot engage; it might contain lint or debris, or it might be faulty or have a bad connection. Clean the mechanism if dirty, and check the switch's wiring harness. Replace the switch if broken.

An FE code indicates a failure with the water-valve assembly, resulting in your washer failing to turn off the water at the pre-determined level. Contact a service technician after shutting off the machine and turning the water valves to the machine off, as it will continue filling if you do not. A PE error code means the water sensor has failed and generally requires replacement.

The UE code for the top loader means the same issue as the front-loader machine – an unbalanced load.

TE and LE error codes generally require a service call, as these indicate electronic or motor issues. A TE error is likely due to a failed temperature sensor. An LE error indicates a restriction in the drive motor or a loose wiring connection in the drive system or possibly a bad control board.
