Unplug machine. Remove back panel and ground screw, remove the drum, remove the coil and electrical connections. Cut zip tie at the bottom, remove the plastic wrapper and electrical connections, remove clips holding harness in place, remove and replace harness and rotor position sensor, put back together. I used 12v impact with 17mm for the center nut. 12v ratchet small extension 10mm for coil, small flathead to help remove connections and sensor, 12v impact with Phillips bit for the back panel, and snips for the zip tie. Have a zip tie with you to replace it
