If the E1 error appears on your treadmill, it may be possible to fix it home by making a few simple checks; or, you may be able to tell whether the repair needs to be performed by someone competent with replacing the motor. This article will guide your through the necessary checks to see whether you can remedy the error source.

Steps

  1. Note that the E1 treadmill error code may appear under three different situations:
    • The “Start” button is pushed and the E1 error code is displayed immediately.
    • The “Start” button is pushed, the display counts for 3 seconds, the DC Motor begins to run and then stop after 6 seconds, when the E1 error code is displayed.
    • The “Start” button is pushed, the display count for 6 seconds, and then the E1 error code appears. The belt does not move in this situation
  2. Deal with potential wiring problems. If the E1 error code shows immediately, it is likely a wiring connection problem. Check the connector at the back of the display, in the handlebars and at the bottom of the right side support post. Make sure that the connectors are turned the right way, that none of the pins are bent and that they are firmly pressed together.
    • If this does not solve the problem, you may have a problem with a wiring harness. Check to see if the harness was damaged during assembly by visibly inspecting the harness where the handlebars and the support post are connected during assembly and where the support post is inserted into the base. If there are signs of damage, you can isolate the mid-section of wiring harness and test to see if this is the problem through removing the display from the handlebars and attaching it directly to the end of the wiring harness coming out of the right side of the base. If the display now works properly, replace the damaged wiring harness.
    • If this does not resolve the problem, remove the bottom hood cover and replace the wiring harness from the controller board to the base.
  3. Deal with motor speed issues. If the E1 error occurs after the belt starts to move for several seconds, the error code means that the system is not picking up the speed of the motor. This pickup comes usually from a magnet mounted on the front roller pulley and a speed sensor, or a problem with the magnet. To resolve this problem, follow these steps:
    • Check the connection between the speed sensor and the controller board. This connection will be sealed with hot glue to keep it from loosening. Make sure that the connection is secure without removing the hot glue.
    • Make sure that the magnet is properly installed on the front pulley. If you cannot locate the magnet on the pulley, order a new magnet.
    • Replace the magnet and/or sensor.
  4. Replace a defective motor if needed. If the previous steps do not solve the problem, this is likely because the error is caused by a defective motor (too much current need from the motor causes the board to enter protection mode and stop the treadmill belt).
    • If the E1 error shows after the display, count the workout time for 6 seconds. If the belt never begins, the error code means that the DC motor controller is likely defective and needs to be replaced. The problem could also be associated with a defective motor.

Tips

  • Damage on boards occur in 20 percent of cases due to a defective motor.[citation needed]
  • A defective motor is associated in 10 percent of cases to wear and tear of a running belt.[citation needed]

Warnings

  • To prevent electrical shock, be certain the treadmill is turned off and unplugged before cleaning and maintenance.
