Possible Causes

Severely clogged exit needle, Collapsed K-Cup filter, Scale buildup at outlet, Weak pump unable to maintain flow

How to Fix / Troubleshooting

Safety first: Unplug and let the brewer cool before cleaning.

  • Deep clean exit needle: Remove the K-Cup holder and soak it in warm soapy water. Use a paper clip to clear the exit needle from both sides.
  • Descale: Run a full descale to remove scale at the outlet and internal passages.
  • Test with different pods: Try a different brand or batch of K-Cups to rule out defective pods.
  • Monitor pump sound: If the pump strains or stops under load, it may be failing and need replacement.
