Why does my Andrew James AJ001337 filter overflow when making 12 cups of coffee?
- DdanielrayAug 20, 2025
The filter may overflow due to the grind being too fine, causing water to flow slowly and back up. This issue is exacerbated by the maximum volume of coffee beans and water used for 12 cups. To resolve this, select a coarser grind or reduce the number of cups to decrease the coffee and water volume.
