I was using my DK City treadmill and suddenly it stopped and flashed E7 and now as soon as you press the start button it starts flashing E7 and won't start up. What is wrong with my treadmill and how do I fix it?

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.Jun 30, 2021

(from the User's manual)

Hello,

With the motor cover off and the power on, make sure there is a red light/led lit on the controler, if yes then press the start button then press #3 on the speed side. If not lit, you dont have power to the controller. If you had a red light, and pressed the speed button, the light should start flashing just before the walk belt starts to move. If the speed button is pushed and the light on the controller does not flash, you have a problem in the console. This is only fixed by replaceing the controler.

Sorry.

Hope this was at least helpfull, Matt
