What can I do when the treadmills appear E-5 error?
Try to pull the belt to see if it can be pulled.
a. If possible, please unplug the power supply, let the treadmill rest for 5-10 minutes, then plug it in again, pull the belt again, and see if it works properly;
b. If it doesn't work, observe whether the display shows the wrong E-X prompt.
2. What can I do when the treadmills appear E-1 error？
The E-1 error means that some lines have disconnected. There are 2 lines on the right handle: the top one and the bottom one. Please check they are connected or not.
