Great video, I have an E06 issue too. A upon just a visual checking I found that most capacitor's were showing signs of damage and leaks I went ahead to swap them out with new ones. Treadmill worked for a while about 4 days then same Error 06 returned. What could be the issue? I got the treadmill to work again by removing the 3pin inclined connector from the board so no incline function but treadmill is working.
