Possible Causes
Incorrect installation settings (breaker size, max current), Corrupted configuration memory, Firmware update incomplete, Installer misconfiguration via app or DIP switches
How to Fix / Troubleshooting
Safety first: Configuration changes should match the installed circuit capacity. Do not set current above breaker/wire rating.
- Verify installation settings: Using the FLO app or installer interface, confirm the charger’s maximum current is set according to the breaker and wire size.
- Restore defaults: If available, perform a factory reset per FLO’s instructions, then re-enter configuration values.
- Re-run commissioning: For models requiring commissioning, repeat the setup process to ensure all parameters are stored correctly.
- Firmware update: Check for and apply any recommended firmware updates.
- If E17 persists after proper configuration: The configuration memory or microcontroller on the main control board may be faulty and require board replacement.
