How to Fix / Troubleshooting
Safety first: Turn OFF power before opening the EVSE.
- Check ambient and ventilation: Ensure the EVSE is not overheating due to blocked vents or high ambient temperature.
- Inspect PSU area: Look for bulging capacitors or discoloration near the low-voltage power supply components.
- Reseat connectors: Firmly reseat any plug-in low-voltage harnesses between PSU and control board.
- Verify line voltage: Have an electrician check for significant voltage dips under load.
Persistent rebooting usually indicates a failing PSU or control board that should be replaced.
