6. Troubleshooting
If you encounter issues with your GODIAG EV Charger, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not powering on / LCD screen is blank. | No power from the outlet; loose connection. | Ensure the power plug is fully inserted into a working outlet. Check the circuit breaker. |
| Vehicle not charging. | J1772 connector not fully inserted; vehicle charging settings; charger fault. | Ensure the J1772 connector is securely latched into the vehicle's port. Check your vehicle's charging settings. Observe the charger's LCD for any fault indicators. |
| "Fault" indicator on LCD. | Overvoltage, overcurrent, short circuit, or other protection activated. | Unplug the charger from both the vehicle and the power outlet. Wait a few minutes, then reconnect. If the fault persists, contact customer support. |
| Slow charging speed. | Using Level 1 instead of Level 2; current setting is too low. | Ensure you are using a NEMA 6-20 (240V) outlet for faster charging. Adjust the current setting on the charger's LCD to a higher amperage (up to 16A). |
If these steps do not resolve the issue, please refer to the "Warranty & Support" section for further assistance.
