    Late in the cycle it stops with LE error code. I replaced the Hall effect sensor to no effect. I also cleaned some gunk and lint from the water outlet above the door.
    Washer has long smelled mildewy if left closed. We will do a clean cycle with Tide WM Cleaner today. Not confident that will fix the LE error.

Fault code LE indicates that the main control board detected the drum not moving. It's either the Hall sensor is not working, the rotor is locked/restricted, the hall sensor wire harness is broken, or the main control board is faulty. The Hall sensor is replaced so this leaves the other three need to be checked.

The first thing to check is the motor. Remove the rear cover to access the motor then run the machine. Once the code appears, try to turn the rotor to verify whether it is stuck/locked or not. If yes, then the problem is the motor. Otherwise, check the continuity of the wire harness connecting the main control board and the Hall sensor. Replace the wire harness if it's broken or shorted. The problem lies in the main control board if the wire harness, hall sensor, and the motor are all good.

    When I put it in QC mode none of the functions associated with turning the drum work. All others do. I bought a new Hall sensor, which didn't fix it. Continuity on the Hall sensor harness checks OK from the main board to the Hall sensor. When I remove the motor connector from the main board and check the resistance between all terminals on the unplugged connector I get a consistent 8 ohms or so between all 3. So I think both the stator and stator harness are good. I'm thinking that definitively makes the main board the culprit, right? What's the part number? I ordered the Hall sensor from Edwards Electronics in Santa Clara (I'm in Oregon).

    You should try turning the rotor manually when the fault code appears and the machine stops. Time to replace the main if the rotor turns freely. The main board is part number 6871ER1023Q.

This is a compiled notepad document of mine:

You MUST use "HE" (High Efficiency-Low Suds) type detergent--but to use the correct amount.
Nearly all brands of "HE" detergent have incorrect instructions.

The correct amount is as follows:

HE: (2) Tablespoons Per Washload

HE 2X (double concentrated) : (1) Tablespoon

HE 3X (triple concentrated): (1) Teaspoon

This reduces/prevents:

1) Musty Odor

2) "LE" Error/Interrupted Cycle

3) L-O-N-G Cycle Times (longer than time displayed)

4) Insufficient Cleaning Results

5) Small Water Leaks from the air vent behind the washer or at the
front door gasket

6) Damaged Hall Effect Sensor (on 2007 or older LG washers)

7) Reduced Spin Speeds (laundry not spin-dried effectively)

Most consumers were doing what is *normally* the right thing to do, which is to follow directions on the detergent label. In this rare case--those directions should be entirely disregarded.

Additionally--in many LG washers--the liquid dispenser cup (blue cup) has a "MAX" line on the white siphon cap.
This was a very big *faux pas* on LGs part--this "MAX" line has NOTHING to do with measuring detergent and should never be used as a guide for determining correct detergent amount.
The "MAX" line indicates how much liquid must be in the blue dispenser cup before it DISPENSES from the bottom of the cup.
This is a very,very frustrating mistake that gives owners much grief.

After three months of incorrect type of detergent or incorrect amount of the correct detergent used--musty odor begins to occur.
After more than two years--a significant amount of soap scum/curd has accumulated in the washer. Odor-causing bacteria flourishes on this build-up.
It is imperative to remove this slimy residue. Tide sells a product called "TIDE WASHING MACHINE CLEANER" which is very effective.

Once a tub has become heavily contaminated--normal methods of performing a TUB CLEAN cycle won't "cut it".

Add the entire packet of "TIDE WASHING MACHINE CLEANER" directly into the tub (no laundry) and close the door.

Press and hold: SPIN SPEED & SOIL LEVEL buttons--then press POWER button.
Wait for door to lock.

Press the START button (6) times--this will fill the tub with hot water to the maximum setting when it stops filling.

Press the START button two more times--this will enable the tub to tumble.
After 3 hours--turn "off" the washer.
Turn the washer back "on".
Select the shortest wash cycle (usually "quick wash") and press "START". This will rinse out the tub.
This method of "TUB CLEAN" is *not* from a service manual but has been the best method for cleaning out LG washers more than a year into incorrect detergent useage.

After this--use the correct amount of "HE" detergent & perform a "TUB CLEAN" cycle every (4) months using the *tub clean* option on the control panel.

Most digital-controlled front load washers have a software feature that consumers are unaware of.
If excess suds is detected by the MAIN BOARD (which monitors motor electrical load during rinse & final spin) the "suds kill mode" will be enabled.
This causes the washer DISPLAY CLOCK to stall.
The washer makes an attempt to reduce/remove suds--usually a futile attempt--and ends the cycle much longer than was originally shown on the DISPLAY.

************************
Problem:
An occasional LE error but always a slow or no spin: Solution:
The Red wire going to the Hall sensor was intermittent. You can test this from the main board connector down to the connector on the hall sensor by checking continuity. There is an intermediate connector down by the motor/hall sensor so you can isolate the problem even more. My problem was in the short wire harness that connects directly to the motor and hall sensor. I could not find the open point of the wire so I added a new red wire and integrated it into the harness. All is Good!!!
**********************
Problem:
The seal design on the washer traps water causing mildew to grow.
Solution:
If the door gasket has a small hole at the six o'clock position--it is clogged with soap scum. Use compressed air to blow this hole clear.
This allows water to drain back into the tub
If there's no hole--this is an older model LG which did not have this upgrade
Wiping the door gasket with a rag after the LAST cycle of the day helps prevent debris from accumulating. Some consumers add (1) teaspoon of bleach to a spray bottle with water--and spray the older type gaskets after the final laundry load finished--to keep the gasket clean.
*********************
Problem:
The detergent and softner dispenser is gravity feed and builds up with "gunk". It has to be cleaned regularly and while the tray is removable, the inlets are not; so you have to fish out the sludge with a paper towel.
Solution:
This common on almost all front load washers.
Remove the dispenser tray. Remove the blue liquid detergent cup. Add all to the top rack of the dishwasher---run a cycle. This makes much less a chore of cleaning the dispenser tray assy.
********************
Problem:
The washer broke down about 6 months ago (roughly 2-2-1/2 years old). The waste pump went bad. No service reps in the area and the place that sold them to us quit selling LG after numerous complaints. I went to a local appliance parts wharehouse that sells just about every part known to the appliance world and when I mentioned LG, the guy at the counter smiled and shook his head. "You have to order it online.
***********************
Solution:
You are correct---parts & service is still lacking in some areas, regrettably.
**********************
Problem:
The dryer has an auto dry feature which never fully dries the clothes so we wind up manually setting the dry time to an hour
**********************
Solution:
LG gas dryers are VERY temperamental in long vent set-ups. If fabric softener sheets are used in the dryer--clean the two stainless steel strips of metal on the lint filter housing with a SCOTCHBRITE PAD--scrub back & forth several times to remove the waxy residue from the fabric softener sheets. Most,if not all manufacturers do *not* recommend using sheets in dryers that have a moisture sensor (electrodes).
However--using a SCOTCHBRITE pad keeps the wax off those sensors which can be seen if looking *into* the dryer drum and at the lint filter housing.
If only *liquid* fabric softener is used in the washer--clean the dryer sensors once a month. Liquid softener also contains wax which can slowly accumulate on the dryer sensors from the laundry washed in the washer.
**********************
Problem:
With no error code showing up and the glitchy flickering of the display, I'm eyeballing the main board.

**********************

Solution:
Unfortunately--that appears to be the fault (main board) if the lights for the cycles that circle the control panel knob flicker or do not fully "light up".

Main Board Part # 6871EC1121D

**********************

Problem:
Getting a CE error code

Solution:
This is a *rare* error.

It's highly unlikely the motor is at fault.

Detergent overuse triggers an "LE" error rather than "CE".

UNPLUG THE WASHER...

First--inspect all wiring connections at the MAIN BOARD (see below instructions). If good...

Inspect the wiring at the motor--remove the rear service access panel.

Remove the 17mm bolt at the center of the rotor--this can be tight as threadlocker is used (I use an 18 volt Dewalt Impact drill).

Pull off the round shaped rotor. Use some care--this rotor has magnets lining the inside of it--it's not super fragile but can crack if hit sharply.

Inspect the two plug connections to the motor for loose or frayed wiring. Also inspect the wiring which runs from the base (bottom) of the washer-to-the-motor. Once or twice--I have found wiring frayed from the gyrating tub assembly (repair as needed).


If no obstruction such as a nail or similar object can be seen in the drum (small holes in tub)...if the drum turns freely by hand--the most likely fault will be the MAIN BOARD has failed.

This job is very simple:

Remove (3) screws at the top of the control panel.

Pull the control panel towards you & upward.

Remove the screws that attach the MAIN BOARD to the Display Board. Install new MAIN BOARD.

How do I fix a loose or locked up drum that generates LE errors?


you sure it is not and upside down 'F' instead of an L? that would be a hall sensor(motor position sensor) error. easy fix. check out appliancepartspros.com or repairclinic.com for both parts and videos that show how to repair. very easy with common tools. about 20-30 minutes. basically take back cover off, remove motor cover, remove stator, replace part.

My lg wm0742hga front load washer machine over fill of water.


Hello Felipe;

My name is Peter. I am a retired field service appliance technician.

The LE error code stands for "Locked Motor Error." This is one of the more common error codes on LG washing machines. Ii is a fault condition. Read your manual where it explicitly tells you to use only High Efficiency (HE) detergent. Although, regular detergent is less expensive, using other than HE, you are going to continue to have problems. Such as premature drum bearing failure.This is an expensive repair.
In the LG washer, the LE error code is usually caused by the burned out hall effect sensor, Part Number: 6501KW2002A.

25306720-ivjmlkku3sgjajtrwwedo0fi-4-0.jpg


1.) Unplug your unit and remove the back cover.

25306720-ivjmlkku3sgjajtrwwedo0fi-4-3.jpg


25306720-ivjmlkku3sgjajtrwwedo0fi-4-8.jpg

Be absolutely certain that the HALL EFFECT SENSOR is installed correctly. Three white plastic tabs on the STATOR (motor) securely hold the sensor in the correct position. If any of the *three plastic tabs* were damaged during an attempt to remove the old sensor-this will require replacing the STATOR ASSY
Also, Check for any black marks on the wires or burns or broken wires.

LE error (checked stator and replaced HAll sensor already)


If the control board does not receive the input it will not operate does the door lock? However:
The attachment shows how to diagnose and repair a failed hall sensor, the usual cause of
an LE error code.

DO NOT replace the stator until the hall sensor has been tested. 98% of LE error codes are
caused by failed hall sensors.

[DD motor SVC check process ]

Pre Check
1) Gentle wash cycles, such as Perm Press, Delicates, Hand Wash, and Wool/Silk should only be used for
smaller loads. Because these cycles are more gentle in tumbling and spinning, putting too much in the
drum can register an issue with the motor. Remove items, reset unit and test with a Rinse/Spin cycle.
2) Don't replace the PCB when the hall sensor is replaced.
Check the hall sensor as shown in the new process.
O have a file I can send but can not upload here if you want it, contact me melissamaemartin@yahoo.com please put hall sensor in subject line. Thanks

Error code LE indicates that either the motor is not turning or has locked up for some reason. It can also be due to Hall sensor which monitors direction and speed of the motor. If the sensor is faulty then also this error appears. Motor lock can be caused by several things from a loose connector, to a bad motor. To make sure it's not a locked motor, try turning the drum with your hand. And, if there is any resistance while turning the drum or the drum doesn't move freely then the motor is locked and you'll need to get it replaced. If the motor seems to be fine then you would need to replace the Hall Sensor. To replace the hall sensor, take the back cover off. Take the big nut off and remove the motor rotor. Remove the bolts holding the motor windings. Remove the electric plug on the sensor and unclip it from the motor winding. --------------- Unplug the unit from main outlet.Then drain the water from the machine.By disconnecting the drain pump ,There will be too much water so be care full.If you disconnect the drain pump from drain hose to drain the water it will flow on you,so keep towels ready to soak the water. Also clean the water filter. ----------------- In most of the case LE error is solved by just disconnecting the washing machine from main power outlet for 30 minutes.But if the problem is still the same then try cleaning the filter and draining the water from drain pump.This error occurs when motor stops functioning and water does not drain. --------------Also another cause of LE error is Regarding the LE ERROR CODE. This code is also caused by having a residue on the sensors in your unit. You have to use a HE liquid detergent.If you use fabric softener use half of the recommended amount and dilute if it is concentrated. Once a month (for a family of four) put 3 cups of white distilled vine-ager directly into the drum and select sanitary cycle or the hottest cycle you can. This prevents residue from forming in your unit and causing the LE ERROR CODE. ---------------- This should help.Thanks.Helpmech,.

Spinning Motor is overloading


Hi


Thanks for using FixYa. LE error is a communication error between the control board and the motor. In you LG washer the Hall Effect sensor board monitors the direction and speed of the motor and sends this information to the control board. Usually the issue is with this Hall Effect sensor going bad and should be replaced. However, to make sure it’s not a locked motor, try turning the drum with your hand. And, if you feel some resistance while turning the drum or the drum doesn’t move freely then the motor is locked and you’ll need to get it replaced. If it is fine then it is the Sensor. Please do rate the solution if the issue is resolved or post a comment for further assistance.

What does an ''LE'' code mean on a LG Model WM2075CW


Hi


Thanks for using FixYa. Make sure the error is not IE, which means water has not reached to the pre-set level within 4 min. since ERROR inlet valve operated or water has not reached to the normal level within 25 min.

The 'LE' error message indicates the control board has detected that the motor is either not turning, or has locked up for some reason. Monitoring the motor is the job of the Hall Effect sensor board which constantly determines the direction and speed of the motor and feeds that information back to the control board. If there is a problem between what the motor should be doing and what the hall effect sensor says the motor is doing, the 'LE' will be displayed and the cycle will be stopped.

Motor lock can be caused by several things from a loose connector, to a bad motor, or even the hall effect sensor failing or dislodging from it's mount. Any one or more of these components could have caused this error, but it is possible to separate the working from the non-working, just by following a process.

To make sure its not a locked motor, try turning the drum with your hand. And, if you feel some resistance while turning the drum or the drum doesn’t move freely then the motor is locked and you’ll need to get it replaced.

The hall sensor is rather easy to replace, and is covered by a seven year part warranty (in US). Take the back cover off. Take the big nut off and remove the motor rotor. Remove the bolts holding the motor windings. Remove the electric plug on the sensor and unclip it from the motor winding. Snap new sensor on and reassemble. Usually takes under a half hour.

Also check for ---



  • Check for the Connector (3 pin, male, white) in the Wire Harness, check if it is connected to the Connector (3 pin, female, white) of MOTOR. Reconnect or repair the connector.
  • The electric contact between the connectors¡a3 pin, male, white in the Wire Harness and 6 pin, female, white in the PWB ASSY(Main) is bad or unstable.Reconnect or repair the contact in the connector.
  • The Wire Harness between the MOTOR and PWB ASSY(Main) is cut(open circuited).Repair the damaged (open-circuited) WIRE HARNESS
  • The hall sensor is out of order/defective.Replace the PWB ASSY(Main).

Please do rate the solution and revert for further assistance.

LE error on LG wm1814CW


My wife and I had the same LE error on our LG washer intermittently in the past. We have already been down the road to replacing the Hall Sensor only to find the washer not spinning and displaying the LE error again. Here is what we have found to be the remedy: Being that the Hall Sensor is a "Position" Sensor, we made a conscientious effort after unloading the washer to place the drum in the same position as when it finished its spin cycle. It has now been about 3-4 months with NO "LE" ERROR on the washer!!! One other thing - if you currently have the error displaying, you will have to unplug the washer for at least 2 hours to erase the memory of the drum position. This way you start fresh with a good position. Just leave it unplugged overnight. Hope this helps out!
