Although using an electric kettle to boil water seems simple, many people still make mistakes that shorten the lifespan of the appliance and pose health risks. Electric kettles are popular in many households due to their convenience — just add water, turn on the switch, and you’ll have boiling water in minutes. However, there are common mistakes that can damage the kettle or even endanger your health. Here are 5 typical errors — 9 out of 10 households make at least one of them:

1. Buying Any Type of Kettle Without Considering Material

Many assume that any kettle will do, as long as it boils water. Some opt for cheaper options without considering quality. In reality, you should choose a kettle made from 304 stainless steel, which is resistant to corrosion and high temperatures. Water boiled in such kettles is generally safer for consumption.

2. Overfilling the Kettle

Filling the kettle to the brim is a common mistake. When the water boils, it may overflow and leak into the base, causing short circuits or damage. Always follow the maximum fill line marked inside the kettle. Exceeding it not only risks malfunction but also compromises electrical safety at home.

3. Turning on the Power Before Adding Water

Some people switch on the kettle before adding water. This can lead to "dry boiling," where the kettle heats with no water inside, potentially burning the heating element or causing a short circuit.
Best practice: Add water first, place the kettle on its base, then plug it in and turn it on.
Also, make sure the base is dry before placing the kettle on it — any leftover moisture could lead to electrical hazards. Always unplug the kettle after use.

4. Pouring Out All the Water Immediately After Boiling

After boiling, it’s common to pour all the water into a thermos or container. However, don’t empty the kettle completely. Leaving a small amount of water inside prevents the thermal relay from drying out due to the residual heat of the base, which could reduce the kettle’s lifespan.
Later, discard the leftover water and rinse the kettle before the next use — this helps preserve the device.

5. Rarely Cleaning the Kettle

If the inside of the kettle isn't cleaned regularly, yellowish mineral deposits can build up over time. These not only affect water quality but also pose health risks.
To clean it, pour in white vinegar and half a bowl of water. Boil the mixture, then let it sit for about 10 minutes before pouring it out. You’ll notice a significant reduction in scale. Wipe clean with a cloth to fully remove residue.
Vinegar works because it’s acidic and neutralizes the alkaline scale buildup inside the kettle.
