Quoting from the link shown:

" An E6 or E7 error code is an incline error code. The E7 code means the potentiometer value the console is reading from the lift motor is out of range. This can happen when there is a bad wire harness connection or a damaged wire harness. It could also just mean the incline motor needs to be adjusted back into range. If all wire connections look good, the incline motor will need to be adjusted.

1. Turn the power OFF, wait 5-seconds and turn back ON.
2. Get into test mode and enter through the I/O testing step. This screen will display the potentiometer value of the incline motor. Different models will have different values. Check to see if the running deck is raised to high incline level or if it is at the low level. If the running deck is at a low position press the incline up button. This will cause the incline motor to raise the running deck up. When the deck gets to a mid-level position, press the incline up button a second time to stop the deck. If the running deck is in a high incline position, use the incline down button to adjust the deck to a mid-level position.
3. Once the unit is in the mid-level position, power the treadmill off for 5-seconds and then power it back ON.
4. Start the treadmill.
5. Once the treadmill starts the running deck will move to the level 0 position. If this does not resolve the issue or it will not adjust please contact customer service.
