How to Fix / Troubleshooting

Safety: Allow hot coffee to cool before handling the brew basket to avoid burns.

  • Manual test: Remove the brew basket and operate the drip-stop lever or button by hand. It should move freely and open the outlet.
  • Cleaning:
    • Soak the brew basket in hot soapy water for 15–20 minutes.
    • Use a small brush to clean around the drip-stop mechanism and outlet hole.
  • Inspect spring and seal: Check that the spring returns the valve to the closed position and that the seal is not deformed. Replace the brew basket if parts are damaged.
