Amperfied User Interface / Control Lockup

Charger display or LEDs are on, but the unit is unresponsive to button presses, RFID cards, or app commands.

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

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Firmware hang, Faulty touch/button panel, Damaged RFID reader, Overloaded CPU due to communication errors

Safety: This is typically a low‑risk control issue.

Hard reboot: Turn off the charger at the breaker for at least 2–3 minutes, then restore power.
Test local controls only: Try starting a session with RFID or local button, with the app closed, to rule out app communication issues.
Check for firmware updates: Use the Amperfied app or service interface to update firmware if a newer stable version is available.
If still unresponsive: A technician may need to replace the front user interface panel or main control board after diagnostics.
