How to Fix / Troubleshooting
Note: Software faults can often be resolved without hardware replacement.
- Hard reboot: Turn off the upstream breaker for at least 60 seconds, then restore power and observe if the charger boots normally.
- Check update history: If E015 appeared after a firmware update, use the ABB app or service tool to verify update status and reapply the update if necessary.
- Factory reset: Perform a factory reset from the user interface or app, then reconfigure essential parameters.
- Offline update (technician): A technician may use an ABB service dongle or USB/serial interface to reload firmware directly to the control board.
- Replace control board: If the microcontroller or flash memory is damaged and cannot hold firmware reliably, replace the main control board.
