Possible Causes

Incorrect current limit setting in Siemens configuration app or DIP switches, Mismatched phase configuration (single vs three-phase), Corrupted configuration memory on control board, Unauthorized firmware or parameter set

How to Fix / Troubleshooting

Safety first: Do not exceed the rated current of the supply circuit when changing settings.

  • Review installation manual: Check the Siemens documentation for correct DIP switch or rotary switch positions for your supply type and breaker rating.
  • Use configuration tool/app: If your model supports app or web configuration, connect and verify that maximum charging current, phase mode, and country/grid settings are correct.
  • Factory reset: Perform a factory reset according to the Siemens manual (often via a button sequence or configuration interface). Re-enter required settings.
  • Firmware consistency: Ensure that any firmware updates were applied using official Siemens tools and that the process completed without interruption.

If E008 persists after a verified factory reset and correct configuration, the non-volatile memory on the control board may be damaged and the board may need replacement.
