How to Fix / Troubleshooting
Safety note: This is typically a low‑voltage signaling issue, but always avoid opening the unit while energized.
- Test with another EV: Determine if the issue is specific to one vehicle model.
- Inspect connector and cable: Check for damage to the pilot pin and cable as in E01.
- Update firmware: Use the GoCable app or service portal to update the charger's firmware to the latest version, which may improve compatibility.
- Reduce electrical noise: Ensure the EVSE circuit is not sharing conduit with high‑frequency drives or large motors that can inject noise.
- If E13 persists across vehicles: The pilot modulation circuit on the main control board may be defective and require board replacement.
