### Common Mistakes with Electric Kettles

1. **Choosing Any Kettle**: Opt for a stainless steel kettle, preferably made from 304 stainless steel, to ensure safety and durability.
2. **Overfilling**: Don’t exceed the maximum water level to avoid overflow and potential short circuits.
3. **Turning on the Kettle Before Adding Water**: Always fill the kettle first, then switch it on to prevent damage from dry boiling.
4. **Pouring All Water After Boiling**: Leave some water in the kettle to protect the thermal relay and prolong the kettle’s life.
5. **Neglecting Cleaning**: Clean the kettle regularly to prevent scale build-up. Use vinegar and water to remove residue, ensuring safe and healthy boiling.
