How to Fix / Troubleshooting

Safety first: This is primarily a control issue; standard electrical safety still applies when opening the unit.

  • Power cycle: Turn off the breaker for at least 2 minutes, then restore power and observe LED behavior.
  • Check EO app status: See if the app reports a pending or failed firmware update. If so, follow EO's instructions to retry the update.
  • Factory reset (if available): Use the documented procedure to perform a factory reset, then reconfigure the charger via the app.
  • Stable power during updates: Ensure the charger is not switched off during any firmware update process.
  • PCB replacement: If the charger remains in an undefined LED state and cannot be recovered via software, the main PCB may need replacement.
