Thomas K Colorado Springs , CO July 12, 2020 Appliance: LG Washer WM4270HWA/00 Lg Washer Wm4270hwa/00: Le error code happened on each cycle type. How to replace Washer Rotor Position Sensor Assembly. Did all the easy troubleshooting steps, and then checked the motor. It spun freely so I knew it was probably the Hall Sensor and/or the wiring harness. Removed the rear cover, disassembled the motor cover, stator, and wiring harness. Then I replaced the Hall Sensor. Then reassembled everything and voila, it was fixed. No error codes.
