Display shows “Error 5”; machine may not move the brew group or may stop mid-cycle.

Safety first: Unplug the machine before working near the brew mechanism.

Step 1 – Reseat the brew group:

• Remove the drip tray and grounds container.
• Remove the brew group (if user-removable), then reinstall it carefully, ensuring it locks fully into place.
• Check that the service door closes completely.

Step 2 – Clear debris:

• Inspect the brew group tracks and surrounding area for coffee buildup.
• Clean with a brush and vacuum to ensure the group can move freely.

Step 3 – Reset the machine:

• Plug the machine back in and power on; allow it to attempt its initialization.

Step 4 – Advanced sensor checks:

• With the housing removed (unplug first), locate the brew group position microswitch or optical sensor.
• Check that the actuator on the brew group actually reaches and triggers the sensor.
• Test the microswitch with a multimeter for proper open/close operation.

Step 5 – Replace faulty parts:

• Replace a defective microswitch or optical sensor.
• If the brew group frame is warped and no longer aligns with the sensor, replace the brew group assembly.
• If the sensor signal does not reach the board, the wiring harness or main control board may need replacement.
