How to Fix / Troubleshooting

Safety first: Unplug the unit and allow it to cool before touching the warming plate.

  • Verify function:
    • After brewing, carefully feel near (not directly on) the warming plate to see if any heat is present.
  • Check auto-off:
    • Some models turn off automatically after 2 hours; confirm the unit is still on.

If the plate never heats, the warming element or thermostat is likely open. Testing and replacing these components involves mains voltage and should be done by a technician.
