6. Troubleshooting
If you encounter any issues with your desk, please refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Desk does not move / No power | Power cable disconnected, power outlet issue, control box malfunction. | Check power connections. Ensure the outlet is working. Try a different outlet. If still no power, contact support. |
| Desk moves unevenly or stops | Overload, obstruction, uneven weight distribution, synchronization issue. | Reduce weight on the desk. Check for obstructions. Ensure weight is evenly distributed. Perform a reset (see below). |
| Error code displayed (e.g., E01, E02) | Motor fault, sensor issue, overheating. | Refer to your physical manual for specific error code meanings. Often, a reset or power cycle can resolve temporary errors. If persistent, contact support. |

| Unusual noise or smell | Internal component issue, motor strain. | Immediately unplug the desk. Do not use. Contact FLEXISPOT customer support. |
6.1 Reset Procedure
A reset can often resolve minor operational issues. The exact procedure may vary slightly, but a common method is:
- Press and hold the Down (v) button until the desk reaches its lowest position and then slightly rises and lowers again.
