Possible Causes

Burned-out warming plate element, Faulty warming plate thermostat, Failed control board relay, Broken wiring to plate

How to Fix / Troubleshooting

Safety first: Unplug and allow the unit to cool before removing the base.

Confirm symptom:

  • Immediately after brewing, carefully hover your hand above (not on) the warming plate to feel for heat.

Internal inspection (advanced):

  • Remove the bottom cover to access the warming plate element and wiring.
  • Check for loose connectors or burnt wires.

If the element is open or the thermostat is faulty (requires testing), the warming plate assembly should be replaced. If wiring and plate test good, the control board relay may be defective.
