Possible Causes

Faulty temperature sensor reading too low, Stuck warming plate thermostat, Excessive warming plate temperature setting, Coffee left on plate for too long

How to Fix / Troubleshooting

Safety: Unplug and cool the unit before internal checks.

  • 1. Adjust usage:
    • Avoid leaving coffee on the warming plate for extended periods; transfer to a thermal carafe if possible.
  • 2. Check warming plate thermostat:
    • Access the underside of the warming plate and locate the thermostat.
    • Test its opening temperature if possible (requires controlled heating) or replace if suspected stuck closed.
  • 3. Inspect temperature sensor:
    • Test the NTC thermistor for correct resistance; a sensor reading too low will cause overheating.
    • Replace the sensor if out of specification.
  • 4. Control board calibration:
    • If all hardware checks out but coffee is still excessively hot, the control board may be misregulating temperature; replace the main control PCB.
