Possible Causes

Overheating triggering thermal cutoff, Loose internal power connector, Failing control board, Faulty power switch contacts

How to Fix / Troubleshooting

Safety first: Unplug the coffee maker and allow it to cool fully before further use.

  • Improve ventilation: Move the unit away from walls or cabinets to allow better airflow. Avoid placing it under low-hanging cupboards where steam accumulates.
  • Check for moisture: Wipe away any condensation around the control panel and lid. Excess steam can affect electronics.
  • Test on a different outlet: Plug directly into another wall outlet to rule out loose receptacles or power strips.
  • Observe pattern: If the unit always shuts off at about the same time in the brew cycle, the thermal cutoff or control board may be overly sensitive or failing.
  • Professional inspection: Internal wiring, thermal cutouts, and the control board should be checked by a technician if the problem persists.
