Check wiring from thermister to control board.

I do not have a solution, but have the same exact problem and would like to know if you ever found out where the thermistor is and if you were able to fix it.
Thank you,

SOURCE: Getting error code on lg front loader washer
Hello aj546,
Kinda figured there was a miscue there with your error code however... the error code FE refers to the fact that water is overflowing ( normally means the inlet water valve is stuck open and continues to let in water beyond the expected and/or sensed level.. so the water pump turns on to drain it and keep the level down. This kind of problem would probably warrant a aservice call from a tech since the majority of troubleshooting would require diagnosing the failed component itself and is not something that I recommend you try. There are too many pieces of hardware that have a direct impact on how this works and I highly doubt you want to play the shotgun approach..try this to see if it fixes the problem and if not..try that...
Before calling for service.. try this..
remove or disconect ac power from the washer..let it sit unplugged for at least an hour..then try washing 1 towel at the lowest cold water setting to see if that works ..if it does..repeat the process using only hot water.. if that works... then try the same test using warm water.. ( this test may help determine if the water inlet valve .,.either hot or cold is leaking through it)... If you still get the FE test..call for service.. That's the best I can offer via this chanel... BTW..if only one of the two tests fails.. ( Hot water only generates an FE error.. then chances are the hot water inlet solenoid valve assembly is either sticking open or the controls to that are commanding it to remain open... Hope that helped you..'
Regards,
Rick

A "tE" error code is more than likely the "thermistor". Supposedly can't be serviced by untrained individuals (thus the directions to call for service) but the thermistor can be found easily by tilting the machine on its back. It is mounted to the back of the drum housing. I removed mine after getting a "tE" error...cleaned and replaced...no problems since! No screws needed to be removed. My thermistor is a small, round, black rubber grommet with the metal sensor pushed through the center. I removed the entire grommet. It easily pops back into place.

LG Tromm Washing machine te error. The manual says to call for service. Not much help there. The reason for the error is the thermistor circuit (resistive element that becomes less resistive as it increases in temperature). The thermistor acts as a heat sensor. In many cases, the error occurs because the wireing harness is too tight at the bottom of the drum and one of the wires in this circuit becomes disconnected with all of the movement of the drum (unbalanced load, normal cylcing etc).
1. Unplug the washing machine from the wall. The thermistor circuit is at line voltage (110 in the U.S.) and it will bite! So do this first before proceeding.
2. Move the washer out so you can get access to the back of it.
3. Remove the stainless panel (the one that is not painted, it is large (aprox. 16x18 inches). It is held in place by 4 phillips screws.
4. Locate the thermistor connection block near the bottom of the machine, at the center of the wash drum. It is the small white connector that has two wires running to it. One wire is dark blue, the other is light blue. Insure that neither wire has pulled out of the connector. If either of them have, repair the connector and provide enough extra wire ( aprox. 2") to provide cable relief.
5. If the cable connector and wires are ok, there are other solutions here that recommend either cleaning or replacing the thermistor.
Good luck to you.

Yes - repeated tE error solved by simply making sure the connections to the thermistor are tight. I had repeated tE error codes - my wife called service, and when the service man I told him I thought that the tE was a thermistor error...he said "this machine (WM2455HW) doesn't have a thermistor - it is all solid state". It sounded suspicious to me ... and then he "placed his hands on the machine" (claiming that it wouldn't reset by the button combination) and pronounced that we'd need a $290 control board (you can get them for $155 at Sears) and $170 labor + tax.
All of this just didn't make sense to me since 1) a thermistor IS a solid state device, 2) an intermittent problem is RARELY a problem with the solid state electronics (though occasionally, components can overheat and fail intermittently), 3) everything I'd read suggested the tE indicated a thermistor error...and 4) intermittent errors are OFTEN caused just by poor connections on electronic devices.
Well, I dug into the machine, found a thermistor (clearly labeled on the wiring diagram inside the machine), tipped the machine on its back to get access to the thermistor, unplugged the connector to the thermistor and pulled it out of the rubber grommet that anchors it to the wash drum. Then I squeezed the connectors on the female plug end to make a tighter connection and reconnected everything. I then opened the main control board and unplugged all plugs and reconnected them in case there was a bad connection to the main control board.
Guess what - everything works fine now - NO PARTS - and yes, there was a thermistor in the washer (the service man wasn't correct in saying there was no thermistor).
I am concerned that this may be a real scam. Certainly it could be that the service man comes out, says it is a control board, charges for a control board and in fact replaces the board even though it is still good. Taking the old (and new-appearing) control board to the next house where the same claim is made. They can pocket the $290 and the service call.
I probably would not be so cynical about this except for the fact that the service man specifically contradicted what I said about suspecting a thermistor problem and told me specifically that there was no thermistor in this washer (my wife witnessed this).
How can you trust the service folks anyway?
