Possible Causes

Overheating of heating element, Failing thermal fuse or thermostat, Loose internal power connection, Control board fault

How to Fix / Troubleshooting

Safety first: Unplug the unit and allow it to cool for at least 30 minutes.

User actions:

  • Ensure the coffee maker has adequate ventilation and is not pushed against a wall or under low cabinets trapping heat.
  • Perform a full descale cycle to improve heat transfer and reduce overheating.

If the unit consistently shuts off mid-brew even after descaling and ensuring ventilation, an internal thermal device or control board may be failing and should be serviced.
