This is general guidance based on the ChargeX MREC standard. Actual charger behavior varies by manufacturer and firmware version. Always follow on-screen instructions and contact the charging network if you are unsure.

Critical

The charger has detected an internal fault that it cannot recover from automatically. This is a charger-side problem, not something you caused.

What to do

  1. Try a different connector on the same charger
  2. Move to a different charger if available
  3. Report the unit to the charging network with the error message if visible on the screen

Who's responsible?

  • This is likely a charger hardware issue
