Filling the kettle to the top may seem harmless, but it can be risky. When water boils, it may spill over and seep into the base, increasing the chance of electrical damage or short circuits.
Every kettle has a marked maximum fill line inside. Staying below this limit helps ensure safe operation and extends the life of the appliance.
3. Switching It On Before Adding Water
Some people turn the kettle on before pouring in water, especially when filling it separately. This can be very damaging.
Without water, the kettle enters a dry-boil state. Even short dry-boil incidents, if repeated, can burn the heating element, damage internal parts, and raise the risk of electrical failure. Always add water first, then place the kettle on the base and turn it on. Also, make sure the base is completely dry before use, and unplug the kettle afterward for extra safety.
4. Pouring Out Every Drop After Boiling
It’s common to empty all the water into a thermos or container right after boiling. However, leaving a small amount of water inside the kettle is actually better.
