It is not uncommon to see breakdowns on a kettle. It is a very useful utensil to heat water quickly. It has a heating resistor to reach a high temperature.

Care must be taken to maintain this machine to enable it to have a longer life and to prevent the parts in contact with water from being damaged.

If you can turn on the kettle, descaling the appliance can solve many heating problems. If the kettle does not heat up, it will be necessary to check:

  • the power outlet
  • the electrical panel
  • the power cord
  • pedestal
  • the connector
  • resistance
  • the electronic card

A kettle that’s not heating can be a significant inconvenience, especially when you’re in dire need of a hot drink. In this article, we’ll explore some common reasons why a kettle might stop heating and offer potential solutions to get it back up and running.

Why Is My Kettle Not Heating?

Reason 1: No Power

The most straightforward reason for a kettle not heating is a lack of power. This could be due to a number of issues, from a faulty plug or outlet to a tripped circuit breaker.

Solution: Firstly, ensure that the kettle is correctly plugged in and the power outlet is functioning. You can test the outlet by plugging in another device. If the outlet works but the kettle still isn’t heating, the issue could be with the kettle’s cord or plug. It’s advisable to have these checked by a professional to avoid any risk of electric shock.

Reason 2: Faulty Heating Element

The heating element is a crucial component of a kettle, responsible for heating the water. If the element is faulty or has burned out, the kettle won’t heat up.

Solution: A faulty heating element is often a complex issue that requires professional attention. If you suspect the heating element is the issue, contact the manufacturer or a professional repair service. In many cases, it may be more cost-effective to replace the kettle.

Reason 3: Limescale Build-Up

If you live in a hard water area, limescale can build up inside the kettle over time. Significant limescale accumulation can interfere with the kettle’s ability to heat water.

Solution: Regular descaling can prevent and solve this issue. Most manufacturers will provide instructions for descaling, and some may recommend specific descaling products. Alternatively, a simple solution of equal parts white vinegar and water can be used. Fill the kettle with the solution, let it sit for an hour, then boil the kettle and rinse thoroughly.

Reason 4: Faulty Thermostat

The thermostat is responsible for regulating the kettle’s temperature. If it’s faulty, the kettle may either not heat at all or not heat to the correct temperature.

Solution: If the kettle’s thermostat is faulty, it generally needs to be replaced. This task should be left to a professional to prevent any risk of electrical issues.

Reason 5: Automatic Shut-Off Feature Activated

Some kettles come with an automatic shut-off feature that turns off the kettle if it’s empty or if there’s not enough water. This feature is designed to prevent damage to the heating element.

Solution: If your kettle shuts off immediately after being turned on, make sure it’s not empty or nearly empty. If the kettle still doesn’t heat, it might have a faulty sensor triggering the automatic shut-off feature, and you should contact a professional for repair.


Some kettles have an electronic card located inside the base. If this electronic card is defective, the kettle will not be able to work.

  • Set the multimeter to continuous mode or to the minimum value of ohmmeter mode.
  • Place the black tip of the multimeter on the solder on the white wire of the electronic card, which is just below its contact, then the red tip on the metal part connected to the white wire connected to the connector.
  • If your multimeter reads 1 or OL, then the wire is bad and you need to replace the electronic card.


A kettle not heating can be frustrating, but understanding the possible causes can help you solve the problem more effectively. Some issues, like a lack of power or limescale build-up, can be resolved with simple solutions. However, for more complex issues like a faulty heating element or thermostat, professional help is recommended. Regular maintenance, such as descaling, can also prevent many issues and extend the lifespan of your kettle.
