Possible Causes

Keep-warm timer set too low, Failed warming plate element, Faulty hot plate thermostat, Control board shutting off early

How to Fix / Troubleshooting

Safety first: Avoid touching the warming plate directly; it can still be hot.

  • Check settings: Adjust the keep-warm time and temperature (if available) to a higher setting.
  • Test plate temperature: After brewing, carefully feel near the plate (without direct contact) to see if heat is present. If completely cold, the element may be open.
  • Power reset: Unplug for 5 minutes, then plug back in and test again.
  • If plate never heats or shuts off within minutes: The warming plate element, thermostat, or control board may be defective and require replacement.
