How to Fix / Troubleshooting
Safety: Determine and correct the underlying cause (overcurrent, ground fault, overheating) before attempting to clear the lockout.
- Review fault history: In the Emporia app, check recent events to identify which fault occurred repeatedly.
- Correct root cause: Address any wiring, load, or environmental issues indicated by prior errors (e.g., E03, E05, E09).
- Power cycle: Turn off the breaker for 5 minutes, then restore power to clear temporary lockouts.
- Factory reset: If allowed by Emporia documentation, perform a factory reset to clear persistent software lockouts.
- If E17 remains after all corrections: The control board may have a permanent safety latch or hardware fault and should be replaced.
