Possible Causes

Corrupted firmware or configuration on main control board, Faulty pilot PWM generator, Incorrect maximum current setting in Blink configuration, Damaged pilot output stage

How to Fix / Troubleshooting

Safety first: Do not attempt to modify firmware unless instructed by Blink. Turn off power before opening the unit.

Steps to troubleshoot:

  • Reboot and reset: Power cycle the charger at the breaker. If available, perform a soft reset or factory reset via the Blink user interface (refer to model-specific manual).
  • Verify current settings: Using the Blink display or web/app interface (for networked models), confirm that the maximum current setting matches the circuit breaker rating and installation.
  • Firmware update: If supported, check via Blink network/app for pending firmware updates and apply them following Blink’s instructions.
  • Internal inspection: With power OFF, inspect the pilot output components on the main control board for obvious damage (burn marks, cracked components).

If E11 persists after configuration verification and firmware update, the main control board’s pilot generator circuit is likely defective and the board should be replaced by an EVSE technician.
