How to Fix / Troubleshooting
Safety warning: Do not pry off buttons or open the front panel; this can compromise sealing and expose live parts.
- Dry the panel: If the charger was recently exposed to rain or washing, allow the front panel to dry completely.
- Press each button: Gently press each button multiple times to see if any are stuck or feel different.
- Use default settings: If charging still works at default current, you may temporarily use the charger without changing settings while arranging service.
- Service: Non‑responsive buttons usually require replacement of the display/UI board.
