A kettle made from low-quality metals can leach chemicals when heated. The result is water that may affect long-term health. This risk is invisible, which makes it easy for people to ignore.
Mistake 2. Filling the kettle all the way up
A kettle filled beyond the maximum line becomes a hidden danger. Once the water reaches boiling point, it expands. Some can spill over and seep into the base. Contact between water and electrical components creates a serious hazard. Short circuits and permanent damage are common consequences.
Every kettle includes a maximum fill line for a reason. It exists to protect the appliance and the user. Respecting this line is one of the simplest ways to extend the life of the kettle.
Mistake 3. Switching on the kettle before adding water
Some people place the kettle on its base, flip the switch and then fetch water. This sequence seems harmless, yet it triggers a dry-boil. Within seconds, the heating plate becomes extremely hot with no liquid to regulate temperature. One incident might not show immediate damage. Repeated dry-boils weaken internal components until failure occurs.
