I'm getting an error code of tE and the washer will not operate. I have removed the thermistor and it ohms out at 47k ohms. The heating element ohms out at approximately 42 ohms. the connections at the thermistor and heating element are good though I have not checked the connections at the control panel. What do you think is wrong with the washer?
Answer Hello Paul,
There are three things in this circuit. The thermistor, the wiring and the control. I have actually had arguements with the manufacturer because they would not admit that the control that reads the information the thermistor is sending has circuitry inside it that can fail and the readings were being mis-interpreted. If all connections are good and the thermistor is reading good through the wiring harness from the control end, the control 6871ER1062D has to be the issue.
We have this LG washer/dryer when you turn it on it gives us fault code EE minus the horizontal line on the top of the first E and beeps does not let you do anything.I looked it up on the fault codes .it tells me (water temperature trouble & unplug and get serviced)I thought it would be something with heating the water.I spoke to one repair guy he thinks it is the thermistor.What do you think.I have pulled the face of the machine off so i can see everything.
Answer Kon, You're getting close. Since you have the front off the machine, remove the wires from the heater terminals 5301FR1158D and check for a resistance reading of 10 to 30 ohms, this will tell you if the heater is intact. Then Remove the wire connector from the thermistor 6322FR2046C and check for a resistance of 2.5K and 180K ohms with a multi meter and make sure the thermistor hasn't backed out or loosened in the rubber heater housing. If all checks are OK, you'll need to check the wiring(especially at the terminals on the thermistor) and at the control board 6871EC2005A.
What should the resistance be of the thermister for the LG WM-16220-fd?
The resistance value when checking at the main control board should be between 2.5K and 180K ohms and if not then replace the thermistor.
