6. Troubleshooting
If you encounter issues with your Bokman EV Charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not powering on. | No power from outlet; loose connection. | Ensure the power plug is fully inserted into the wall outlet. Check the circuit breaker for the outlet. |
| Charging does not start when connected to EV. | Vehicle not ready to charge; charger not fully connected to EV; current setting too low. | Ensure your EV is ready to accept a charge. Verify the SAE-J1772 connector is fully seated in the vehicle's port. Check the current setting on the control box (adjust before connecting to car). |
| Cannot change current setting. | Charger is connected to the vehicle. | Disconnect the charger from the vehicle first. Then, use the "Current" button to adjust the amperage. Reconnect to the vehicle to begin charging with the new setting. |
| Cannot stop charging from control box. | Buttons are disabled when connected to the vehicle. | To stop charging, first press and hold the "A" button on the control box for several seconds until a prompt appears (if available), then confirm. Alternatively, unplug the charger from the vehicle, or use your vehicle's internal controls to stop charging. |
| LED indicator shows an error. | Internal fault; protection activated (e.g., over-temperature, over-voltage). | Unplug the charger from both the wall and the vehicle. Wait a few minutes, then reconnect. If the error persists, contact customer support. |
