How to Fix / Troubleshooting
Safety first: Do not repeatedly clear faults without identifying the underlying cause.
- Step 1 – Review error history: If available via LCD or Wi-Fi, check the error log to see which fault triggered the service message (e.g., repeated GFCI FAULT, OVER TEMP).
- Step 2 – Correct root cause: Address the underlying issue (ground fault, overtemperature, etc.) following the relevant troubleshooting steps before attempting to clear the service flag.
- Step 3 – Power cycle: Turn off the breaker for 1–2 minutes, then restore power and see if the SERVICE REQUIRED message clears.
- Step 4 – Firmware reset: Use the configuration menu or web interface to perform a soft reset or clear fault history if the hardware is confirmed good.
- Step 5 – Contact support: If the message persists with no identifiable hardware fault, contact OpenEVSE support or replace the main control board.
