How to Fix / Troubleshooting

Safety: Clean up any spilled hot coffee carefully to avoid burns.

  • Verify settings: Check the selected cup size and ensure it matches the carafe capacity.
  • Cancel extra cycles: Make sure the brew button is not stuck or being pressed twice.
  • Reset programming: Restore factory settings (refer to Braun manual) to clear any incorrect custom programs.

If the machine continues to overfill despite correct settings, the flow meter or control board may be miscalculating volume and needs service.
