Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug and allow the plate to cool completely before inspection.
Steps:
- Check settings: Ensure the keep-warm function is enabled and that the auto-off timer has not expired.
- Visual inspection: Turn the machine over (unplugged) and remove the base cover. Inspect wiring to the hot plate for burns or disconnections.
- Resistance test (advanced): Measure resistance across the warming plate element. An open circuit indicates a failed element.
- Replace faulty parts: Replace the warming plate assembly or thermostat as needed. Reassemble and test.
