LG washer tE error code

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.

The source of a "tE" error code is more than likely the "thermistor". The other possibility is the heating element, or its power source on the control board, or both. Or some bad wiring from any of these two components to the control board. I chose to check the easier-to-troubleshoot and the more common source of the problem first, the thermistor.

First I disconnected the AC power.

The thermistor is easily accessed by first tilting the washer backward about 30-45 degrees leaning against the wall. I propped it up with a block so I can crawl under the washer safely to access the thermistor. I reseated the connectors by removing and reinserting the connectors several times to clear any possible corrosion on the contact points. I didn't remove the rubber grommet of the thermistor. Instead, I slid the thermistor's metal body out of the rubber boot, cleaned it and slid it back in the boot.

I ran an empty load and set it for high temperature setting. While it's running I pressed the temperature button and the display showed the actual temperature reading in Celsius. Somewhere on other forum they indicated that the expected temperature at high temperature setting should be around 70 degree C. Assuming the built-in heater is functioning, the washer should be able to raise and maintain the water temperature at whatever level it's programmer for. Well, in my case the reading was creeping up ever so slowly and at the end it still read lower even though the washer still ran through the test completely without error. I wasn't completely happy with the result as with the wide margin of the temperature feedback, the machine may act up again and the same tE error may resurface.

As an EE, I just happened to have a tube of heat sink compound grease at my disposal. You can get this from Radio Shack for just a few bucks. I crawled back down and took the thermistor metal body out of the rubber boot again and put some of the heat sink compound on it, enough to liberally cover the whole surface, then slid it back in the rubber boot. The temperature reading is now much closer to the expected value. The machine is working great again.

My te code turned out to be a broken wire at a junction with the thermistor wiring. I separated the joiner, pared the side off the plastic joiner to expose the metal of the connector, since the wire had broken off inside it. I stripped about 3/16 inch off the end of the broken wire and soldered it back to the clip. Now the two wires to the junction are unequal lengths, so I ratchet tied them firmly so they were even for a couple of inches back to ease any load on the soldered joint. After I plugged the junction back together I covered the exposed section by wrapping the junction a couple of time with electrical tape. BUT i couldn't flip the machine over to get to the thermistor as it has the dryer on top, so I had to take the front off it. But it is necessary to REMOVE THE RUBBER SEAL at the circular door, to allow removal of the front panel everyone said a special tool was needed, BUT THE SPECIAL TOOL IS NOT NECESSARY...YOU DO NOT HAVE TO PAY $ AND WAIT FOR DAYS!!..... and LG's illustration of its special tool, in the service manual, is confusing at best. The SPRING has to be EXTENDED to release the light wire retainer that secures the door seal. I MADE MY SPECIAL TOOL FROM AN OLD PAIR OF CHEAP SCISSORS. I simply filed "V" notches on the OUTSIDE of each blade of the scissors close to the ends. The NOTCHES PREVENTED SLIPPING off the ends of the spring when PRESSURE WAS APPLIED IN THE REVERSE DIRECTION... forcing the scissor BLADES APART and thus opening the spring and releasing the retaining wire. The wire only has to clear part of the rubber and can then be rolled clear of the rest. Once the wire is out, the rubber seal is easy to clear away so that the front panel can be removed. When reassembling, the retaining wire can be stretched back in place with your hands only...and the scissors are still useable! Safety..as usual with springs, wire and scissors, protect your eyes.

I was easy, after locating thermistor, checked connector, it was fully seted, pushed it on all the way, problem solved. thanks

According to my manual,tE says it's a CONTROL ERROR and the solution is to unplug machine and call for service. Hope that helps.
