Charger’s front LEDs blink in an undocumented pattern and the unit behaves erratically, but no code is shown in the app.

Safety first: Normal LED troubleshooting does not require internal access; if you open the unit, turn OFF power first.

• Power‑cycle: Turn OFF the breaker for 60 seconds and then back ON to reset the controller.
• Firmware update: Check the Volvo app for available firmware updates and apply them.
• Factory reset: If behavior persists, perform a factory reset of the charger configuration (per manual) and re‑set basic settings.

If LEDs remain erratic but charging works normally, the issue may be limited to the LED board or driver. If charging is also unstable, seek professional diagnosis.
