How to Fix / Troubleshooting
Safety first: Unplug the machine and allow it to cool before removing the bottom cover.
Basic checks:
- Confirm that the warming function is enabled and that the timer has not expired.
Internal inspection (advanced):
- Remove the bottom cover to access the warming plate connections.
- Test the warming plate element for continuity with a multimeter.
- Check the thermostat or thermal fuse attached to the plate.
- Inspect the control board for a burnt heater relay.
Replace the warming plate assembly or thermostat if defective. If the relay is burned, the main PCB will need replacement.
