Trevor for Model Number WM2277HW I have managed to keep my 15 year old LG Tromm washer going with new seals and a new spider over the years. What is the likely cause of the rotor/drum locking in seemingly an electromagnetic way when power is applied to the stator and then unlocking as soon as the power stops? A hum accompanies the motor trying to spin. The problem first presented itself as the washer filling up and then trying to agitate but only stuttering and then eventually an LE error code would show up. I checked continuity through the harness and wires all the way to the control board. I ohmed the stator and the reading were consistent across the wires. And my voltmeter showed what appeared to be 150V, 240V, and 250V (confusing since it is a 120V appliance) using a neighbor's old analog voltmeter as my digital one presented strange readings with multiple decimal places. Visually, the stator and rotor don't look any different than a couple years ago when I last had them apart. Thanks for your help as my laundry is piling up and the natives are getting restless!
Answer Trevor, you are going to want to check the wiring harness ensuring that there are no loose connections or damaged wiring. To ensure that no wires are damaged, you will want to do a continuity test on the wiring. From there, you will want to test the resistance of the motor winding. All three connections should read between 5 and 15 ohms when tested from contact 1-2, 2-3, 1-3. All three should ohm the same. If not, then you have a bad winding. If they do ohm out properly, and the wiring harness checks good, then you have a bad hall sensor [6501KW2002A] which is a part of the stator assembly. Read More...
