- Temperature Sensor Protection System: Monitors the internal temperature to prevent overheating.
- Water Level Temperature Sensor: Provides additional protection against operating without sufficient water.
- Over 110℃ Protection: The device will shut down if the temperature exceeds 110℃ to prevent damage.
Common Issues
- Device not turning on:
- Check if the power cord is securely plugged into a working outlet.
- Ensure the water level is above the 'MIN' mark.
- Temperature not reaching target:
- Verify the set temperature is within the operating range (25℃ to 95℃).
- Ensure the pot size is within the recommended 4L-20L range. Larger pots may take longer to heat.
- Check for any obstructions around the heating element or pump.
