Charger randomly reboots or restarts during charging sessions.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

Possible Causes

Unstable internal power supply, Loose low-voltage connectors, Firmware crash, Overheating of control board

Safety first: Turn off power before opening the charger.

Check temperature: Ensure the charger is not overheating; improve ventilation if necessary.
Inspect low-voltage wiring: Reseat connectors between the power supply, main board, and display.
Firmware update: Install the latest firmware to address potential stability issues.

If reboots continue, the internal power supply or main control board may need replacement.
