How to Repair an electric kettle at home when it won’t turn on?

Electric kettles are one of the most frequently used household appliances. They are convenient and easy to use. Just add some water and within a few minutes, you get hot boiling water for your tea, instant food, recipes as well as cleaning. 

Electric kettles are more convenient than the microwaves for heating water as it has a pouring spout. 

But as with any other electric appliance, users come across some troubleshooting. 

Some people purchase a new unit as soon as they come across any failure of operation in an electric kettle. That’s not a good idea because sometimes it requires just minor repairs to start working again. 

Here, I have explained how you can fix a troubleshooting electric kettle at home. 

Tools you are going to need 

  1. Neon tester
  2. Screwdriver
  3. Some wiring cables
  4. Wire Stripper
  5. Plier
  6. Multi-meter
  7. Test bulb / lamp
  8. Gloves
  9. Rubber Shoes

Finding causes of troubleshooting in electric kettle and fixing it 

Repairing an electric kettle is not rocket science. There are only a few components in it. Before repairing the kettle you should know who to locate the troubleshooting component. You can find it by checking each component one by one. The most common defects found in an electric kettle are either they do not heat up or do not turn on. There are many problems that an electric kettle can encounter. 

Let’s know how you can inspect all the parts by yourself at home. 

There are different types of kettles available in the market but they all function in a similar manner. 

Firstly let’s understand, How does an electric kettle work?

Circuit Diagram of Kettle

In the above diagram, you can see when the supply switch in on the supply from the switch flows to the heating element of the kettle. The supply to the heating element is cut off when the pre-set temperature level is reached. 

Different parts of the kettle that need be check when kettle in not working 

Parts to be checked When kettle in not working
  1. Input supply points
    1. Power on switch

Onder to check the power switch just turn the kettle. Keep in mind to always pour water into the kettle before you turn off the kettle. 

Switch on the supply and then also turn on the power on the switch. If the led lights glow, it means the power on the switch is working properly. If not, it’s the troubleshooting part and you have to change it.

  1. Plug and plug cord

First, check for any insulation guard damages on the plug. Then look for any sort of visual damages in the cord and plug. If the cord is broken or has open insulation then replace it.

If the cord is fine then after doing so, check for loose connections or open insulation in the cord unit. With the help of a screwdriver, open the screws and remove the cord unit cover.

Then disconnect the cord terminals from the kettle. After that check, the cord with the help of a test lamp connected in series. 

In order to check the cord plug, you have to check both the phase and neutral wire individually. 

Test lamp connected in series

Firstly, check the phase terminal of the cord, place the cut wire connected in series on the phase terminal of the cord, and the phase terminal of the test lamp on the phase terminal of the plug. If the bulb/lamp glows then the phase terminals are fine. 

Next, check the neutral terminals of the cord, place the cut wire connected in series on the neutral terminal of the cord and place the phase terminal of the test bulb/lamp on the neutral terminal of the plug. In case the test bulb glows, neutral terminals are fine. 

In a similar manner, check the earthing of the cord, place the cut wire connected in series on the earthing of the cord, place the phase terminal of the test bulb/lamp on the earthing of the plug. If the test lamp glows, earthing is also fine. 

If in every test the bulb glows then that means the cord is in working condition. On the other hand, if it does not glow then the cord plug is faulty and you have to replace it. 

Then again check the kettle with water a little above the minimum level. If the kettle led indicator glows but the kettle does not heat water then it means there is no fault in the supply point at the kettle end. The fault lies in the heating element of the kettle.

  1. Auto cut-off switch: 

In order to inspect the auto-cut off switch of the kettle remove the kettle from the base unit. With the help of a screwdriver, open the screws and carefully detach the base cover of the kettle. 

Then locate the auto-cut off switch and check for any visual damages. In case it’s damaged, replace it.

In case the auto-cut-off switch is fine, then check the heating element of the kettle. 

  1. Heating Element: Firstly, locate the heating element and its connections in the kettle. After that with the help of a multimeter check for continuity. 
  • Set the multimeter dial to resistance. 
  • Place the red probe of the multimeter on the phase terminal of the heating element.
  • Place the black negative probe of the multimeter on the neutral terminal of the heating element. 
  • Check the reading in the multimeter
  • In case the multimeter shows 0 ohm reading, that means the heating element of the kettle is faulty. 
  • In case the multimeter shows a reading greater than 1 ohm, that means the heating element of the kettle is faulty. 
  • You can also check the heating element with the help of a test bulb connected in series.
    • Place the phase terminal of the test bulb on the phase terminal of the heating element and the  cute wire connected in series on the neutral terminal of the heating element. 
    • If the test bulb does not glow, that confirms that the heating element is faulty.
  • In that case you have to change the heating element of the kettle. But, in some of the kettles it’s not possible to change the heating element therefore you have to change the kettle.
