I have the same issue with my 542e. I found that if I do the calibration method using the down incline button and keep do that, it eventually goes down. But, everytiime that I power on the 542e, the incline goes thru a partial up and own cycle and stops at an incline higher than it started. So, after time of use, it eventually ends up at full incline and I need to do the calibration thing again I have the same issue with my 542e.

I just bought a new 505 CST, and from the gate the incline has not worked properly. I can go all the way up to 10, but not with anyone on the treadmill. It will calibrate, but that does fix it. Not happy. I just bought a new 505 CST, and from the gate the incline has not worked properly. I can go all the way up to 10, but not with anyone on the treadmill.
