When to Call a Professional

Also seek professional help if you're uncomfortable working with electrical components or if the motor control board shows signs of damage.Frequently Asked Questions
What causes NordicTrack error code E6?
Error code E6 is caused by the drive motor drawing too much current, usually due to an overtightened belt, insufficient lubrication, belt misalignment, or mechanical obstruction in the motor or drive system.
Can I still use my NordicTrack treadmill with E6 error?
No, you should not use the treadmill when E6 error appears as it indicates motor stress that could lead to permanent damage. Stop use immediately and perform troubleshooting steps.
How often should I lubricate my NordicTrack treadmill belt?
Lubricate your treadmill belt every 3-6 months or after every 150 hours of use, whichever comes first. Regular lubrication prevents belt friction that can trigger E6 errors.
Is NordicTrack E6 error covered under warranty?
E6 errors caused by mechanical failures may be covered under warranty, but issues from lack of maintenance (improper belt tension, insufficient lubrication) typically aren't covered. Check your specific warranty terms.
How do I know if my treadmill belt is too tight?
A properly tensioned belt should lift 3-4 inches from the deck center with moderate effort. If it's difficult to lift or won't lift 3 inches, it's too tight and can cause E6 errors.
