This error shows up if motor controller detects a failed part. This isn’t a reset-able error. Treadmill will not allow workouts until serviced.
Solution
Main motor wires/leads could be disconnected at the start of a workout. If the motor is properly connected and in working condition then the drive transistor could have failed. Check Motor Controller.
