How to Fix / Troubleshooting
Safety first: Ensure the machine is connected to a stable power source.

- Recalibrate volume (if available): Some models allow manual programming of cup volume. Reprogram the desired volumes following the instructions.
- Use surge protection: Connect the machine through a surge-protected outlet to prevent future memory corruption.
- Service if persistent: If E15 returns after reset, the control board's memory (EEPROM) may be defective and require replacement.
