An odor when boiling water in an electric kettle can be due to a number of reasons. The following are some of the possible causes of odor and their solutions:

1. New kettle odor

Cause: Newly purchased kettles may contain chemicals or lubricants left over from the manufacturing process.

Solution: Wash the kettle several times, boil a kettle or two and discard the water before using it for the first time. You can also add a small amount of white vinegar or baking soda to clean it.

2. Mineral deposits

Reason: If the water quality in your area is hard, the water contains more calcium, magnesium and other minerals, long-term use will form scale inside the kettle.

Solution: Use white vinegar or citric acid to clean. Mix white vinegar or citric acid with water in a certain proportion and pour it into the kettle, heat it to boiling, then leave it for a period of time and finally rinse it off.

3. Plastic parts

Cause: Some kettles contain plastic parts such as lids, handles or internal filters, which may release odors at high temperatures.

Solution: Make sure all parts that come into contact with water are food-grade and try to avoid direct contact with water. If the odor persists, consider replacing the kettle with one that does not contain plastic parts.

4. Unused for a long time

Cause: When the kettle is left unused for a long time, dust or other impurities may accumulate inside.

Solution: Clean the kettle thoroughly before using it again.

5. Heating element problem

Cause: Heating elements that are covered with limescale, or problems with the heating elements themselves, may also cause a bad odor.

Solution: Clean the heating element and if the problem persists, the kettle may need to be repaired or replaced.

6. Incorrect cleaning method

Cause: Incorrect cleaning methods may result in chemicals remaining in the kettle.

Solution: Use mild detergents and warm water to clean the kettle, avoid using strong corrosive chemicals.

7. Deteriorated seals

Cause: Deteriorated seals may cause odor.

Solution: Replace the seal with a new one.

Solution Procedure:

BEFORE FIRST USE: Wash and boil a few pots of water to remove any odors that may be present.

Clean regularly: at least once every few months to prevent limescale build-up.

USE WHITE VINEGAR OR CITRUS ACID: Deep clean regularly with white vinegar or citric acid to remove scale and odors.

Keep it dry: Pour out any remaining water after use and keep the kettle dry to avoid bacterial growth.

If none of the above measures solve the problem, or if the odor is very bad, it is advisable to consider replacing the kettle with a high-quality one, especially if you choose those that are plastic-free or use food-grade materials.
