Flow Mismatch at High Volume
Brew basket overflows only when making full pot, not with smaller volumes

Possible Causes
Drip-stop not fully opening with full carafe, Grind too fine for full-pot flow, Brew basket outlet partially restricted, Incorrect filter folding at high volume
How to Fix / Troubleshooting
Safety: Avoid burns from overflowing hot coffee.
- Check carafe position: Ensure the carafe is fully seated so the lid fully opens the drip-stop during full-pot brewing.
- Clean and test drip-stop: Verify that the drip-stop opens fully when pressed by the carafe lid.
- Adjust grind: Use a slightly coarser grind for full-pot brews.
- Do not exceed max fill: Fill the reservoir only to the maximum indicated level.
