Possible Causes

Clogged filter basket outlet, Too fine espresso grind used, Paper filter folded or double-layered, Drip-stop valve stuck closed

How to Fix / Troubleshooting

Safety first: Unplug the unit and allow it to cool before cleaning. Hot coffee can scald.

Steps to try:

  • Use correct grind: For Bodum drip machines, use a medium grind, not espresso-fine. Overly fine grounds slow drainage and cause overflow.
  • Check filter setup: Ensure only one paper filter is used and that it is properly seated in the basket. Avoid folding the bottom excessively.
  • Clean basket outlet: Remove the filter basket and rinse thoroughly. Use a toothpick or small brush to clear the drain hole and any built-in drip-stop valve.
  • Inspect drip-stop: If your model has a spring-loaded drip-stop at the bottom of the basket, press it repeatedly under running water to free any stuck coffee oils.

After cleaning, run a brew cycle with water only to confirm proper drainage before brewing coffee again.
