How to Fix / Troubleshooting

Safety: Normal handling precautions.

  • Use correct filters: Ensure you are using the recommended filter size and type for your Moccamaster model (typically #4 cone filters for many models).
  • Rinse filter: Pre-wet the paper filter with hot water to help it adhere to the basket walls.
  • Adjust grind and dose: Use a medium grind and avoid overfilling the filter with coffee.
