Possible Causes
Too much coffee or too fine a grind, Paper filter collapsed or folded, Clogged drip-stop valve, Brew basket not fully closed or seated
How to Fix / Troubleshooting
Safety first: Hot water and coffee can cause burns. Allow the unit to cool before cleaning up spills.
- Reduce coffee amount: Use the recommended amount of coffee grounds and avoid very fine espresso grinds that restrict flow.
- Check filter placement: Ensure the paper filter is properly seated and not folded over the edge of the basket.
- Clean drip-stop: Remove the basket and rinse the drip-stop valve thoroughly. Make sure it moves freely and is not blocked by grounds.
- Seat the basket and lid: Reinstall the basket fully and close the lid until it clicks or feels firmly shut.
- Test with water only: Run a cycle with just water to confirm that overflow does not occur. If it only happens with coffee, adjust grind and quantity.
