Maytage Neptune E3 code - Model MAH8700AWW - machine won't finish cycle

“E3” code – Machine control is attempting to drive the motor but is not seeing any tach response. Visual Check shows motor is not moving. (Locked or Hall Sensor fault.)
Possible causes of ‘E3’ codes: 1. Spin drum stuck – Verify that the spinner moves freely to eliminate this cause. 2. Hall Sensor fails or is loose – When the Hall Sensor fails or becomes dislodged, the control doesn't recognize that the motor is spinning and shuts down. The result will likely be an “E3” code in the worst case, or “SUdS” if it is only getting a partial rpm reading. Check wire harness connector(s) to motor.
Hall Sensor – PCB that is located on the back of the motor that senses motor rpm. It is not a separate part, but rather an integral part of the motor.
