Possible Causes

Failing internal power supply capacitors, Loose low-voltage connector on control board, Overheating of power supply section, Line voltage dips causing PSU reset

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.
