Description and principle of operation of the heating element
TEN is an electric heater responsible for heating cold water coming from the central water system to the washing machine.
Structurally consists of a tubular part W-shaped or V-like shape, inside of which there is a conductor element with a high level of resistance, able to withstand heating to record high operating temperatures.
A special insulator-dielectric with a high thermal conductivity surrounds the heating coil. It correctly absorbs the heat emanating from the heating element, and transfers it to the steel outer shell.
The working spiral itself is soldered by the outgoing ends to the contacts to which the supply voltage is supplied during operation. Nearby is a thermal unit that measures the level of water heating in the washing tub.
When activated through the control unit of any of the processing modes, a command signal is supplied to the heater.
The element begins to heat up intensively and, giving up the generated heat, brings the temperature of the water in the washing drum to the required temperature set by the user.
As soon as the water reaches the desired temperature, the sensor captures and transfers the data to the control unit. The system responds to the information received and automatically turns off the device, stopping the heating of water.
What to look for when buying a new Tena?
Before you go to buy a new TEN in the nearest store, you should familiarize yourself with its design features.
Heater Design Features
All heating elements of washing machines have the same internal structure, but are slightly different from each other in external design. Today it is considered generally accepted straight and curved the form.
Direct are most widely distributed and are used in the bulk of the models of various popular brands.
Curved heating elements look exactly like straight lines, but at a distance of 50 millimeters from the outer bracket, they have a bend of 30 degrees.
The principle of operation of curved elements is no different from analogs of a straight form, and the basic resistance is in the range of 20-70 Ohms.
Curved parts are produced under the structural requirements of certain types of washing machines from companies such as Ardosome models Ariston, Indesit and others.
By the way, the fault codes of the Ariston and Indesit washing machines were analyzed in detail in the following articles:

Types of external coating
Basically TENs have a metal surface with a protective anodized layer. It has high thermal endurance, demonstrates good water resistance and protects the heating part from corrosive manifestations.
However, some brands, for example, Samsungadditionally apply a ceramic layer to their products.
It is believed that it is more durable and significantly reduces the possibility of scale formation as a result of using hard water.
All error codes for Samsung washing machines and troubleshooting methods we reviewed here.
Working power and resistance
The main distinguishing feature of electric heating elements is working power. In different models, it can reach up to 2.2 kW. The higher the baseline, the faster the water in the drum of the washing machine heats up to the required temperature.
Normal resistance instrument ranges from 20 to 40 ohms. However, the part practically does not feel any short-term voltage drops occurring in the network.This is due to the presence of inertia and a rather high resistance of the heating element.
Other important parameters
Choosing the heater for the machine you need to show maximum attention. This will help to acquire an element of the necessary parameters and quickly reanimate the washer for further full and productive work.
A used device is not worth buying. There is no guarantee that it will serve a high quality for a long time. It is better to stay on a new product and purchase it not at the bazaar, but at a company store or service center.
First of all, pay close attention to the length of the heater. Measure it from the edge of the metal flange to the very end point of the heating element.
It is permissible that the new part be slightly larger or slightly smaller than the damaged “native” one. However, the difference in size should not exceed 1.5 millimeters.
The power indicator should also be taken into account. Usually it is indicated on the flange part of the heater. The difference between a damaged part and a new one should not be higher than 150 watts.
If this indicator is significantly exceeded, the operating load on the entire machine will increase, if it is significantly underestimated, the water will heat up too long and electricity consumption will increase.
The presence of a temperature sensor is another fundamental parameter. Separate models of heating elements are not equipped with this part, but have only a hole for it.
This is because very often when the old TENA is burned, the sensor remains in a normal, efficient state and can be fully used further.
Heaters with only a hole for the sensor are cheaper, so the owners can save a little by using a new heating element with an existing temperature sensor.
The shape of the new heater should be exactly the same as the old. If a bent heating element fails, its replacement with a similar one is allowed. These rules are also relevant for direct heating elements.
It is advisable to try to find a new "native" model. If there are problems with the search, it is permissible to buy a universal option suitable for the parameters of existing household appliances.
Absolute coincidence is necessary for the material of which the washing tank is made. Parts mounted under the plastic tank are equipped with a durable rubber gasket.
According to the base width, it can be long or short, depending on the format of the heater itself.
On gaskets for heating elements, a special flange is provided in the area of the flange for a metal tank. It provides clearer fastening of the part in the compartment.
The terminals and fasteners of the new product must be the same as those of the blown one. If they are located a little differently, there will be difficulties with connecting to the wires and additional sealing of the installation site will be required.
Only then the machine will work correctly again and will correctly perform the tasks programmed by the user.
The material of the heating element can be any, as well as the outer coating. There are no strict requirements for these parameters and any deviations from the basic indicators are permissible, since the operation of the washing machines does not affect it in any way.
What you need to know before repair?
In order for repair work to replace the heating element to be as simple as possible, and in the process there should not be unforeseen situations, it is advisable to learn more about its location and the reasons for the failure.
For many washing machines of different brands and manufacturers, the heater is located below. To carry out repairs or replace a part with a new one, you will have to remove the body cover of the machine.
The design of each individual washing machine determines where it is more convenient to get to the heating part - from the front or from the back. The home master decides this question on his own based on personal amenities and preferences.
In some models, the heating element is located on the side and to check or troubleshoot, you need to dismantle the side wall.
Reasons for the failure of the heater
The main reasons why a part malfunctions and loses its functionality are reduced to two positions.
The first is factory defect. It is not common, however, it is impossible to insure yourself against the troubles of such a plan.
Even acquiring the latest generation of luxury equipment, you can stumble upon a defective model. If the machine is under warranty, the issue is solved very simply - the manufacturer for free changes the non-working TEN to a similar, but completely serviceable one.
The second among the main reasons is scale. It is she who settles on the metal casing, negatively affects the heating element and, as a result, deprives it of operability.
The low thermal conductivity of the scale prevents the appliance from transmitting the generated heat to water, while it itself begins to overheat and experiences an increased load. In the end, it just burns, unable to withstand such a volume of thermal energy.
In addition to these negative phenomena, scale creates conditions for the formation of corrosion on the surface of the module. Over time, this leads to a violation of the integrity of its metal shell.
A device that has lost its tightness becomes vulnerable to external influences and the risk of a short circuit, fire, and other fire hazard situations increases significantly.
The use of improper detergents, for example, powders for hand washing, or the constant excess of the powder volume by one procedure, can disable the heating element.
As a result of unreasonable user actions, a dense impermeable film of soap concentrate is formed on the surface of the part. It creates a barrier to normal heat transfer, provokes overheating of the heating element and leads to its subsequent burning.
To avoid this, you have to properly care for the machine, using anti-limescale for washers.
If you do not want to use expensive purchased detergents for cleaning the washer, we recommend that you familiarize yourself with best cleaning methods using improvised means.
How to diagnose a malfunction?
To detect a malfunction, it is not necessary to disassemble the washing machine and test the heating element with a multimeter.
The following failures that appear in the work will tell about the problems:
- during washing, the water does not heat up to the programmed temperature;
- the machine draws water, but quickly stops washing or turns off completely after 5-6 minutes;
- almost immediately after activating the unit in the house or apartment knocks electrical plugs;
- feels an unpleasant, burning smell in the room during work;
- washing quality deteriorates noticeably;
- the case is touched by electric shock.
If at least one of the listed problems is identified, it is necessary to change or repair the heating elements as quickly as possible.
You can remove a broken TEN and replace it with a new one without involving a master from a service organization. To do this, you need a minimal set of tools, a new heating element and a couple of hours of free time.
The lack of experience in such work should not be scary; in this matter, accuracy and sequence of all stages are important.
Stage # 1 - preparation for repairs
When planning to replace the heater in the washing machine, you need to be well prepared and comply with the basic safety rules relevant to working with household appliances.
Among them are:
- Disconnect the unit from the power supply by unplugging the plug.
- Disconnect the machine from the water supply, remove the drain pipe. This item is relevant for models where the heater is located in the rear.
- Use a high-quality working tool with handles having a protective rubberized coating.
- Prepare a plastic container, such as a bucket or basin. It will be convenient there drain the waterremaining in the tank or in internal communications.
After all of the above actions, you can proceed directly to disassembling the machine, and then to extract the damaged heater.
Stage # 2 - selection of necessary tools
To replace the heating element, no specific and expensive equipment will be needed. All that is needed is in the arsenal of every home master who does not even have much experience in carrying out repair work of such a plan.
The list of such things includes screwdrivers of various configurations. Instead, you can use a screwdriver with a basic set of bits, including hexagons and sprockets needed to unscrew the "tricky" screws.
In addition, a wrench for ten or simple pliers will come in handy. These tools will correctly remove the fasteners from the heating element.
To ring TEN and understand its condition, you need a multimeter to ring.
Before starting work, it is better to put these items next to each other so that they are at hand and the master does not need to drop everything and lose time looking for the right tool.
Stage # 3 - gaining access to the heater
Replacing the heating element through the front panel is a laborious and painstaking process. First remove the top outer cover.
To do this, you have to unscrew the screws located at the back of the washer, gently pull the lid first towards you, and then up.
It is necessary to act very delicately so as not to pull out and damage the clips from the plastic, without which it will be physically impossible to return the cover to its original place.
Then slowly pull out the powder container a little forward, press on the lock button inside and carefully pull out the container completely.
For models that do not have a lock button, the container needs to be lifted and pulled over. When the fastening screws become clearly visible, use a screwdriver and unscrew them, and then remove the container.
Then unscrew the screws holding the control panel, remove it and, without resorting to disconnecting the wires, put it on top of the washing machine.
Open the door of the loading door located in the front of the unit. Using a screwdriver, pry off a clamp-type spring holding the sealing collar and carefully remove it, slowly pulling it in a circle. After that, simply remove the rubber from the body and set it aside.
Find the lock screws on the hatch and unscrew them with a suitable screwdriver. Push the lock released from the mount inwards.
Then unscrew the external screws securing the front panel from the bottom and top. Sometimes they are located under the decorative strip below or on the sides or nearby with a drainage filter.
At the end, carefully remove the panel and fold it side by side. Having opened access to the heating element, calmly proceed with the replacement.
Stage # 4 - installation of a new heating element
Regardless of where the TEN is located, front or rear, it can only be replaced in one way.
First, from the contacts of an old, failed device, all wires are disconnected. Usually, they are planted very tightly and to remove you will need to help yourself with a screwdriver.
All actions must be performed slowly and carefully so as not to damage the fragile area of the connection terminals.
The next step is to remove latch - Unscrew the screw holding the heater in place, and then slowly remove the heater.
Before installation of a new heating element it is necessary to clean the locations of the products of exploitation settled there and insert a new fully working element.
It remains to verify the performance of the equipment. Why do you have to first assemble the machine in the reverse order, perform water and sewage connection and test her. If washing takes place in standard mode, then everything is done correctly.
