Possible Causes

Faulty portafilter microswitch, Misaligned group head switch actuator, Worn portafilter lugs not engaging switch

How to Fix / Troubleshooting

Safety: Unplug the machine before accessing internal switches.

  • Check portafilter fit:
    • Ensure you are using the correct Sage portafilter for your model.
    • Lock it firmly into the group head until it reaches the usual tight position.
  • Inspect lugs: Check the portafilter ears/lugs for wear; if they are rounded off, they may not actuate the internal switch.
  • Internal switch (advanced):
    • Access the underside of the group head to locate the portafilter microswitch.
    • Manually press the switch and see if the message changes.
  • Repair: Replace the portafilter if the lugs are worn. Replace or adjust the portafilter microswitch if it is faulty or misaligned.
