Try pressing spin speed and soild level at the same time. Is the temperature about 10 degrees C over the the selected temperature? If no, then try replacing the main board.
Also make sure the thermister isn't loose. That could cause your problem.
If the main board doesn't fix it, then you have to replace the heater assembly.
Im actually looking the the service manual your unit as we speak.

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.

To be more specific, unplug unit. Behind the machine are two plastic kick plates, remove to slide off the top. Once off, two top self tap metal screws and one screw behind panel wall, remove. Remove two detergent screws. Lift electrical panel and set on top of machine. Remove four top screws. Bottom drain has one screw in front, take out plastic cover and one screw in back. Take off rubber by opening door. With a screw driver, prey and lift up the brass spring ring and remove. Then the front panel should slide up and out. Be careful because electric wire is still connected, move to the side of unit. You will then be able to find the thermostat. Unplug and replace, you will need to use the same rubber bushing. Took me an hour, I’m not an appliance repair guy.

SOURCE: Thermistor for LG WM2688H
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?
