An electric kettle has become an indispensable appliance in any kitchen. It quickly heats water and consumes little electricity. However, like any other device, sooner or later it may fail. The reasons for this situation are many, but most often they boil down to the fact that the device does not work due to damage to the heater. Therefore, many are interested in the question of how to ring the heater in a teapot and, if necessary, change it?
Types of Electric Kettles
Principle of operation
To understand what can cause a malfunction, you need to understand the principle of operation of this device. Regardless of the model and its cost, electric kettles work according to one principle: at the bottom there is a main heating element - a heating element, which is connected to a thermostat. When you turn on the device in the network, the heater heats up, gives its heat to the water and brings it to a boil. When the water temperature approaches 100 ° C, steam is formed. It passes through the channel and reaches the thermostat, after which the kettle turns off.
The principle of operation of the electric kettle
Despite the fact that the principle of operation of the device is quite simple, its repair will be easy only for an experienced master. But those who are faced with a similar problem for the first time do not know how to change the heater in a teapot. Only a few prefer to fix the problem on their own, while others go to the store in search of a new device for boiling water.
Private breakdowns
There are a number of typical problems that are directly related to deviations in the operation of the heating element. Among them, it is necessary to highlight:
- Slow heating of water. This malfunction is associated with a heating element, since there is a significant layer of scale on it. Deposits are formed due to insufficient maintenance of the equipment. Limescale is a petrified mineral and salt found in tap water. During the use of the device, they harden and precipitate on the walls, including the spiral. If you do not descale during time, the heater may burn out. For the same reason, the contact rods of the heating element are damaged. Not everyone knows how to ring an electric kettle and establish the cause of the malfunction at home. Therefore, repairs should be entrusted to experienced craftsmen.
- The kettle shuts off prematurely. The reason is quite simple - the scum formed on the heater. The heating element has a fuse that trips during its overheating. For repair it is necessary to clean the device from plaque.
- The kettle does not turn on for a reason break of a thread of a spiral. The breakdown occurred due to scale on the heating element or switching on the device without liquid. A spiral can also burn out due to poor-quality parts that were used in the manufacture of a heating device.
How to find out the performance of a heating element
To understand what could be the reason for the breakdown of the kettle, you need to ring the heater. However, other causes of malfunctions should be excluded first.
- wire burnout;
- breakdown of the power button.
You can call the heater using the measuring instruments at hand.
Multimeter check
Most people who repair equipment have such devices. To do this, turn on the multimeter (tester) in the resistance measurement mode, and then touch the contact rod with one end of the measuring device.If the thread inside the heating tube is broken, an incorrect value will appear on the screen of the tester. The working resistance for a kettle with a power of 2000 W will be 25 Ohms. If no deviations are found inside the tube, then one of the taps needs to touch the contact rod, and the other to the metal tube. If there is no short circuit, then the screen will have an infinite resistance value. And if it is, then it will be fixed and such a heater is not subject to repair.
Checking the heater
Power Supply Test
Checking with the help of the heating element power supply is called as follows: a battery (-) must be connected to one of the heating element rods, and an LED bulb is connected to the pole (+), the second output of which is connected to the other rod of the heating element. If the bulb lights up - the whole spiral.
Check with indicator
Checking the operation of the heating element
This method of verification is dangerous, because it must be done when the device is connected to the network. You need to act very carefully. In the outlet, you need to determine where the phase is. After this, the contact rod must be connected with a piece of wire with a phase. If you touch the opposite shaft with the tip of a special screwdriver, the lamp will light up. And if you lean the indicator against the handset, it will not light. This means that the integrity of the spiral is broken.
How to replace a heater in an electric kettle
To replace the heater in an electric kettle, you need to completely disassemble it:
- remove the cover. To do this, you will need a Phillips screwdriver. Lift the cover and unscrew all the screws;
- remove the handle - at the bottom of the kettle you need to unscrew the screws, then click the handle. Depending on the model, the mechanism may be located at the bottom of the device or directly on the handle itself;
- To dismantle the heater, you need to remove the on / off button of the device, then unscrew the screws that were hidden under the handle;
- after that, the heating element is freely removable. Then install a new heater and assemble all parts back.
Replacing the heater in the kettle
After the repair is complete, be sure to perform a functional check on the device. Replacing a heating element is a quick and uncomplicated process that everyone can handle. When repairing an electric kettle, safety precautions must be observed, especially when checking the appliance.
