Child lock engaged

Release child lock function to resume normal operation of the washing machine

To disengage child lock hold down temperature and eco/rapid together for a few seconds to set and unset the child lock function.

OE

Washing machine has failed to drain the water

This fault code can mean that the pump is faulty as well as blocked, first of all check for a blockage and, if none is found then the likelihood is that the drain pump is faulty. Should you need it, the most common drain pump used on LG washers and washer dryers is this one.

On non-display panel models this fault code is denoted by the lights for 800, 500 and No Spin being lit or flashing.

Check pump filter is clear and there are no obstructions
Check the drain hose for obstruction
Check the drain hose is not kinked
Check the drain pump filter and clean if required
Check the air chamber and pressure sensor hose
Check drain pump, normal resistance is 152-175Ω
Check drain pump rotor
Check connections to water drain pump

IE

Water fill time out

The washing machine has failed to fill with water in a reasonable time.

Essentially this error code is telling you that, for some reason, there is no water being detected filling into the washing machine. The most likely cause of that would be a water valve failure, commonly used water valves for LG can be found here.

On non-display panel models this fault code is denoted by the lights for Pre & Main being lit or flashing.

Check water supply is on, clear and not frozen
Check the air chamber and pressure sensor hose for blockages
Check water inlet valve
Check wiring to water inlet valve
Check connections to water inlet valve
Check the water valve resistances, normal is 3.5-4.5KΩ
Check the main control PCB

dE

Washing machine door detected as being open

Door open error code can also be displayed as "dOE"

Very simple error, the fault code indicates that either the door is indeed open or that the door lock or door interlock mechanism cannot inform the electronics that the door is properly closed. LG door locks are known to and do commonly fail, the common one used in most LG washing machines and washer dryers can be found here with a link to a lower cost alternative part. However the door handle (can be found here) is also a common source of trouble and, if the catch doesn't engage into the lock properly you will get this fault code being displayed.

On non-display panel models this fault code is denoted by the light for the door lock being lit or flashing.

Check door is closed correctly and latched
Check door handle for damage or wear
Check door safety lock if inoperative replace door lock
Check door lock wiring
If there is a clicking sound once or twice when the Start/Pause button is pressed the main control board may be faulty

UE

Washing machine has detected an imbalanced load

This error code is more for information purposes than actually a fault as such. What the machine is telling you is that it has been unable to sort the laundry load and correctly spin without a risk of damage due to an unbalanced load. This error will clear when you restart the machine but do sort the laundry reduce or increase the load as required and for more information on load imbalances please see this article.

On non-display panel models this fault code is denoted by the lights for 1, 2, 3, 4, 5 and 6 being lit or flashing.

Reload the washing machine and attempt to spin again
Check the installation of the washing machine for level and balance
Check for small loads as small loads will cause an imbalance error

SE

Motor fault detected

Can also be caused by be main PCB

This is not a good fault code to see as it will generally be correct and either the washing machine drive motor or the main electronic control PCB is faulty.

Check motor
Check motor tacho
Check all connections and blocks to the motor
Check connections on the main control module
Check main control module

CE

Current error to the washing machine

Can be a short circuit to motor or PCB

This can be caused by a fault on your home electrics and, if that is the case then you will need an electrician to check your house wiring for any abnormality.

Check mains supply
Check main control module
Check main drive motor or stator

LE

Washing mchine motor locked error

See fault code "DE" above as the some information applies to this error code with the addition (thanks BigCol) of the last on the list below, where trapped objects can cause this error code.

Also can be caused by large loads on gentle cycles liek Perm Press, Delicates, Hand Wash and Wool or Silk programs. The gentle cycles can register a problem with the motor if large loads are used on these programs.

Check door is closed correctly and latched
Check door handle for damage or wear
Check door safety lock if inoperative replace door lock
Check door lock wiring
Check the rotor assembly for cracks or breaks in the magnet
Check the hall sensor resistance, usually 5-15Ω
Check the resistance between V-U/UW/W-v on the stator, normally 8-11Ω
Check for any objects trapped that are stopping the drum from rotating

FE

Washing machine has detected an overfill situation

This error code can be caused by overfoaming which is a result of overloading (see this article) or by overdosing or, incorrect detergent as the pressure sensor will falsely read that there is too much water in the washing machine.

Also check the pressure sensor and that the machine has not actually overfilled with water.

On non-display panel models this fault code is denoted by the lights for synthetic, wool, blanket or pre and main being lit or flashing.

Check for overfoaming or over soaping
Check the air chamber and the pressure switch hose
Check water level sensor
Check wiring to water pressure sensor
Check connections to water level sensor
Check main electronic controller

tE

Water heating error detected

For this error code you need to check both the water heater or element and thermistor, basically the washing machine is reporting a fault on the heating circuit with this fault code but it is not capable of identifying exactly where the fault actually lies.

On non-display panel models this fault code is denoted by the lights for 95, 60, 40 and cold being lit or flashing.

Check water heating element
Check heater for contunuity, usually about 24.5-28.5Ω for washing
Check steam heater for continuity usually about 42.5-49.5Ω
Check thermistor or temperature sensor
Check the thermistor resistance, usually about 53KΩ at 25˚C
Check wiring to water heating element
Check connections to water heating element and temperature sensor

PE

Water level sensor fault

This fault code is fairly self-explanatory and tells you that the washing machine has detected an error with the pressure sensor or pressure switch. It is rare to see this error code on LG washers.

On non-display panel models this fault code can be shown by the lights for fuzzy, heating and speedy or super, normal and hold being lit or flashing.

Check water level sensor
Check wiring to water pressure sensor
Check connections to water level sensor
Check main electronic controller

PF

Power failure

The washing machine has experienced a power failure or power input error. Note that the washing machine must be connected directly to a power socket and not a multi connector according to LG.

Check power supply cord is connected correctly and secure
Check that the washing machine is not connected to a multi-way connecting strip
Check wiring and connections between mains radio interference filter and control module
Check the power LED is on, if not replace main control PCB
Check the connectors to the display card to the main control card
