How to Fix / Troubleshooting

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

Steps:

  • Confirm that the keep-warm function is enabled and that the auto-off timer has not expired.
  • After a fresh brew, carefully feel (without burning yourself) if the plate warms at all.

If the plate remains cold, the warming plate assembly or thermostat is likely faulty and requires replacement, which involves opening the unit.
