Possible Causes

Too much coffee in filter, Coffee ground too fine, Clogged brew basket drain, Drip stop partially closed

How to Fix / Troubleshooting

Safety first: Allow the unit to cool before opening the brew basket.

Clear the basket:

  • Open the brew basket and remove the filter and grounds.
  • Rinse the basket thoroughly, ensuring the bottom drain hole is clear.
  • Clean the underside of the brew head/showerhead to remove coffee buildup.

Adjust brewing:

  • Use a medium grind coffee and do not exceed the recommended scoop count for your brew size.
  • Ensure the drip stop lever is fully open before brewing.

Run a water-only test brew to confirm that water flows cleanly through the basket without overflowing.
