T3 Series Treadmill Shows E11 Error Code – How to Fix

Issue:
Customer reports an E11 error on the T3 treadmill, possibly caused by insufficient power supply.

Root Cause:

• Multiple devices connected to the same power outlet can lead to insufficient power supply.

• Using extension cords or power strips may limit current supply.

• The treadmill’s normal running power is approximately 2000W, which may trigger E11 errors if the supply is unstable.

Troubleshooting Steps:

Step 1 – Isolate the Treadmill Power

• Disconnect all other devices from the same power outlet.

• Plug the treadmill directly into a fixed wall outlet (avoid extension cords or power strips).

Step 2 – Power Cycle the Treadmill

• Turn off the treadmill.

• Wait 10–15 seconds.

• Turn it back on and observe if the E11 error persists.

Step 3 – Record Video Evidence (if error persists)

• Record a short video showing:

  • The treadmill plugged into the outlet

  • The E11 error occurring

  • Any other devices connected to the same outlet

• Send the video to customer support for further analysis.

Solution / Recommendation:

• In most cases, restarting the treadmill after unplugging it from the power outlet resolves the E11 error.
