Possible Causes

Normal safety lockout while warming plate is hot, stuck or misreading temperature sensor on warming plate, control board not resetting temperature status

How to Fix / Troubleshooting

Safety first: The HOT indication is a safety feature. Do not attempt to bypass it by modifying wiring or sensors.

Normal operation:

  • Many Black+Decker models prevent immediate re-brewing to avoid overheating. Wait 5–10 minutes for the warming plate to cool slightly, then try again.

If HOT persists abnormally:

  • Unplug the unit and allow it to cool completely (30–45 minutes).
  • Plug back in and check if HOT still appears before any brewing. If so, the temperature sensor may be stuck or faulty.
  • Access the base and inspect the NTC sensor on the warming plate for secure mounting and good contact.
  • Test the sensor resistance at room temperature; compare to expected values from service documentation if available.

When to replace:

  • If the sensor reads out of range or is physically damaged, replace the warming plate temperature sensor.
  • If the sensor is good but HOT remains, replace the control PCB which interprets the sensor signal.
