Possible Causes

How to Fix / Troubleshooting

Safety: Unplug and allow the machine to cool completely before reuse.

Steps:

  • Ensure the outlet (brew head or carafe spout) is not blocked by coffee grounds or scale.
  • Run a full descale cycle to remove scale from the thermoblock or boiler.
  • Verify that the machine has adequate ventilation and is not enclosed in a tight cabinet.

Advanced:

  • Test the brew thermostat or thermal fuse for proper operation.
  • Inspect the NTC sensor wiring and replace the sensor if readings are erratic.

Resolution: Replace the thermostat or thermal fuse if it trips prematurely. If overheating persists, the control board or sensor calibration may be faulty and require professional service.
