TO CLEAR THE MESSAGE – RESTART THE UNIT, HOLD THE INCLINE UP&DOWN + 0 KEY FOR 3 SECONDS
SERVICE REQUIRED: SHUTTING DOWN: AMP-DRAW/OVERHEATING ERROR – CHECK ALL AMPDRAW-RELATED COMPONENTS, ALLOW MOTOR TO COOL DOWN OR APPLY JUMPER WIRE/REPLACE
MOTOR
1. Error Code E1 or Err1
Possible Cause: This error code often indicates a problem with the safety key or safety sensor. The treadmill may not start or stop abruptly when this error occurs.
Troubleshooting: Make sure the safety key is correctly inserted into the designated slot. Check the safety sensor and its connections for any damage or loose wires. If necessary, replace the safety key or sensor.
2. Error Code E2 or Err2
Possible Cause: The E2 error code is typically related to speed sensor issues. The treadmill may show this error if it fails to detect belt movement.
Troubleshooting: Inspect the speed sensor and its connections. Clean the speed sensor and ensure there are no obstructions around the motor or belt. If the problem persists, consider replacing the speed sensor.
3. Error Code E3 or Err3
Possible Cause: The E3 error code commonly indicates an incline motor problem. The treadmill may fail to adjust the incline level properly.
Troubleshooting: Check the incline motor and its connections. Ensure there are no physical obstructions preventing the incline motor from functioning correctly. If the issue continues, contact customer support or a professional technician for assistance.
4. Error Code E4 or Err4
Possible Cause: This error code suggests an issue with the motor or motor control board. The treadmill may not start or may shut down unexpectedly.
Troubleshooting: Turn off the treadmill and unplug it from the power source. Wait for a few minutes and then plug it back in. If the error persists, there might be a problem with the motor or motor control board, requiring professional repair.
5. Error Code E5 or Err5
Possible Cause: The E5 error code is related to the treadmill’s power supply or power board.
Troubleshooting: Check the power supply and ensure it is securely connected to the treadmill. Verify that the power outlet is functioning correctly. If the issue persists, consider contacting customer support or a technician for further assessment.
6. Error Code E6 or Err6
Possible Cause: The E6 error code is associated with an issue in the console or display panel.
Troubleshooting: Turn off the treadmill and restart it after a few minutes. If the error persists, check the connections between the console and the control board. If necessary, replace the console or seek professional assistance.
7. Error Code E7 or Err7
Possible Cause: The E7 error code indicates a problem with the heart rate sensor.
Troubleshooting: Ensure that your hands are correctly placed on the heart rate sensors on the treadmill’s handles. Clean the sensors to remove any dirt or sweat buildup that might interfere with accurate readings.
