Possible Causes

Failed lock actuator motor in Volvo wallbox, Jammed mechanical latch in Type 2 holster or connector, Broken lock position sensor, Obstruction (dirt, ice) in locking mechanism

How to Fix / Troubleshooting

Safety first: Turn OFF the breaker before working on the lock mechanism to avoid unexpected movement.

  • Inspect for obstructions: Check the connector holster and locking slot for dirt, stones, or ice. Clean gently and thaw any ice with warm (not boiling) water, then dry thoroughly.
  • Manual release: Many Volvo chargers have a manual release tab or screw accessible under a cover. Use it to release a stuck connector following the manual.
  • Check actuator wiring (power OFF): Remove the cover and locate the lock actuator motor and its harness. Ensure the connector is fully seated and wires are not pinched.
  • Test after reset: Restore power and command lock/unlock via the app or front button. Listen for motor operation. If silent or grinding, the actuator is likely faulty.

Replace the lock actuator assembly if it fails to move or position feedback is incorrect. If the actuator is good but E10 persists, the control board’s lock driver or sensor input may be defective.
