Possible Causes

Filter basket overfilled with coffee, Clogged filter or drip-stop, Damaged brew head gasket, Misaligned filter basket or lid

How to Fix / Troubleshooting

Safety first: Unplug the unit and allow it to cool before cleaning.

User checks:

  • Reduce coffee quantity: Ensure you are not exceeding the recommended amount of ground coffee for the basket size.
  • Grind size: Avoid very fine espresso grind in drip models; use a medium grind to prevent clogging.
  • Clean drip-stop: Remove and clean the drip-stop valve and surrounding area to ensure it opens freely.

Seal inspection:

  • Inspect the brew head gasket or rubber seal around the shower head for cracks or deformation.
  • Replace the gasket if it is worn or flattened.
  • Ensure the filter basket and lid are correctly aligned and fully closed before brewing.
