LG Washing Machine Fault Codes

These are the most common fault or error codes used in LG washing machines and washer dryers and most of them use the same fault or error codes when they have a problem or a spare part fails.

These fault codes for LG washing machine and washer dryer models will displayed as a digital code, exactly as you will see below, in an LED or LCD panel or display on the front of the washing machine or washer dryer.

Before you start any investigation of the fault or even remove the lid of the washing machine or washer dryer please read and fully understand this article in full and pay particular attention to the safety and information notices at the bottom of this page as they contain extremely important information!

Please remember to support our site by buying LG spares from our spare part store and, if you decide that you really need an engineer please support the local repairers that help make this site possible, you can find an engineer using the engineer search facility.

LG Washing Machine Fault Codes

Like other fault codes these written for washing machine repairers and not for the general public by LG and UK Whitegoods and they assume a certain level of competence on the part of the user in diagnostic routines. We have added some notes to try to assist you in determining the nature of the fault you have but, you will still need to investigate each failure on its own merits. For more help and advice on fault finding on a washing machine please refer to our basic washing machine fault finding guide from this link before you begin.

Please check that any LG washing machine spares recommended are suitable for use on your particular model and production code or serial number. If you are unsure about the suitability of any spare part please ask to ensure that you get the correct spares for your washing machine. Please, don't guess or assume as spares can be altered on a production run with the same model number having several different alternative components used.


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.


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


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


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


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


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


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


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


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


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


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


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

To clear any error except "PE" pressing the start/pause button will normally make it disappear and the washing machine will enter into a paused state.

If the error code "PE" or "tE" are not resolved in about twenty seconds and, in the case of other errors, within about four minutes the power will be turned off to teh washing machine automatically and the error code only will be displayed. In the case of "FE" the power will not be turned off.

Other Common LG Washing Machine Faults

Other common faults that we see a lot on LG washing machines are:

Soap dispenser leaking: this is fairly common and usually you will get water running down the front of the washing machine because the dispenser case is faulty. The most common one used is this one.

Drive belts fail on the non-Direct Drive models and you can find those here.

LG washing machine bearings do fail on both Direct Drive and indirect drive models and many fail on or around the five year old mark. Replacement bearings and seals can be found here but this is a repair that we would advise it best to get one of our recommended engineers to do as it can be a bit daunting to do.

Also, door seals or gaskets seem to be an issue on LG washers, you can find door seals here.

Abnormal vibration on wooden floors is common on LG washing machines and LG released a set of foot cups that do dampen the vibration down a bit (you can buy them here) and they do work to a degree but may not solve the vibration in every instance. Also note that they are supplied as single items and you will probably need four of them.

On the whole the electronics seem okay in the LG machines but, when they do fail they can be expensive to replace. Not so nicely LG encase the actual PCB in resin within a holder for the module so no repairs to the actual module itself are possible, you can only replace it.

More LG Washing Machine Help, Advice & Guidance

Should you need more help and guidance please use the links from this article as most of them will help you to understand your LG washing machine or washer dryer a lot better and probably very much help you in diagnosing the fault you have. Of course there are many other articles on the site that will also help you do this.

In addition you can post in our help and advice forums after registering but please do pay heed to the information below before doing so and read the guides, they are there to help you. But if you are in any doubt at all or don't think you are up to diagnosing the fault yourself please click here to find a local washing machine engineer.

You must understand certain things before you begin or attempt any repairs on your own and we want to make these points very, very clear to anyone that decides to investigate one of these or any other washing machines:

  • We are not responsible for your safety, you are and by using this guide you accept that and accept that any damage that you may cause and work undertaken is entirely at your own risk.
  • We will advise the common causes of the fault codes but we cannot guarantee that any parts or work recommended will resolve the issue. It is entirely your responsibility to diagnose your particular problem and resolve it.
  • We are not responsible for you buying spares that do not resolve the problem, this is down to your own diagnosis not ours.
  • No warranty is inferred, implied or given.
You also have to understand that fault or error codes are not a "magic bullet", they will not tell you what the problem is, they will only offer you an indication of where the problem lies and they are no substitute for good old fashioned diagnostic skills. You can find out more about what fault codes actually tell you in this article. So please be well aware that, even with this new found knowledge you will still have to actually be capable of investigating and diagnosing the problem and this means adhering to basic appliance safety for working on them. As, if you don't and tell the engineers in the forums that you hooked up components to a live feed, worked on a live appliance and so on they will be a whole heap less willing to help you in our washing machine forums because they will assume that you are trying to commit suicide and are not safe working on your machine.

Please do note that manufacturers can and do change fault codes without notice and we cannot guarantee that these error codes will apply to your particular model as all codes apply to a wide range of appliances and not normally any one specific model. To determine if these fault codes do apply to your particular LG washing machine or washer dryer model please post a request to confirm this in the forums.
