Possible Causes

Scale buildup in boiler or group head, Clogged portafilter basket, Weak or failing pump, Overly fine grind or tamped too hard

How to Fix / Troubleshooting

Safety first: Turn off, unplug, and allow the machine to cool and depressurize before removing the portafilter.

  • Adjust grind and tamp: Use a slightly coarser grind and tamp with moderate pressure. Test with an empty portafilter to see if flow improves.
  • Clean portafilter and basket: Soak in hot water with a little detergent, then scrub all holes to remove coffee oils.
  • Descale brew circuit: Run descaler through the brew head according to the manual, then flush thoroughly.

If pressure remains low even with an empty portafilter, the pump or internal passages may be failing and require professional service.
