Fixing an Error 02/08 or Communication error

E10 Series, E10i Console, E8ix Console, Troubleshooting

This page explains what an Error 2 or communication error means and how to fix it.

What does Error 02/08 mean?

Reason 1: Communication cable fault.
The communication cable is how data is sent from the motor to the treadmill screen. The cable is located inside the right upright post of the treadmill base. It can sometimes become trapped or twisted causing the error to show up.

Reason 2: Out-of-date software.
If the software which communicates with the MCB (motor control board) is not up-to-date, it can cause a communication error.

Reason 3: Misaligned system parameters.
If the system or communication parameters are incorrect, it can lead to communication issues.

Reason 4: Fault in the Motor Control Board (MCB).
The MCB has a fault and cannot communicate with the screen.

It is essential to ensure the software is always up to date. The system will try and automatically update however you can check the software versions and start an update manually by following this guide:

Fix 3: Software settings check

As the software settings get optimised from time to time during software updates, it is worth checking that the settings are indeed correct. The setting can be checked by following this guide:

Fix 4: MCB Check

If the previous steps where unsuccesful you can reset the MCB firmware. This could help if the firmware was corrupted from an irregular activity.

If the MCB is faulty a new MCB will need to be provided. The NoblePro team will provide this to you either free of charge (if within warranty time period) or at cost (if outside warranty time period).

Please create a support ticket and someone from our team will be able to help.

Once your new MCB arrives, it is easy to self-fit thus providing the quickest resolution.
