If LG starts washing your clothes in cold water, then there is a problem with the heater. If such a breakdown occurs, the water heater must be replaced.
To save several thousand rubles, you can replace the heating element without the help of a specialist. We will help you do this by describing in detail and showing how such a replacement occurs in an LG washing machine.
Important! We will tell you how to change the heating element in LG front-loading washing machines.
How the malfunction manifests itself
If you notice that the water does not heat up during washing, you should not immediately disassemble the machine. You need to make sure that the spiral is not working, and then determine the reasons for this phenomenon.
First, you should understand that after rinsing is completed, the laundry should not be warm. To save electrical energy, cold water is used, so it is impossible to determine from the temperature of wet laundry whether the heating element is working or not.
The check is performed in a different way: 20 minutes after the start of washing, the palm is placed on the glass of the loading hatch. If it is warm, the heating element is working. A cold surface indicates that the water is not heating up. In this case, you will have to change the heating element.
Many owners of household appliances are interested in what causes the heater to fail. Failure occurs in the following cases:
- Failure of the heating element due to scale. The reason for its formation is hard water, which contains high concentrations of magnesium and potassium salts. When the heating element is turned on, the water heats up and substances settle on the surface of the spiral. After some time, the coating becomes harder, turns to stone, and the entire surface of the part becomes covered with a crust. This leads to a disruption in heat exchange, and the heating element burns out.
- The coil may burn out due to a voltage drop.
When the heater fails, it is replaced, but you need to start with preparatory measures.
How to change the heating element in an LG washing machine
Failure of the heating element - heating element - is a fairly common malfunction in washing machines. Tap water often contains a large amount of mineral salts; as a result, when the water is constantly heated, the element becomes covered with scale, which significantly reduces its service life. As a result, the machine stops heating the water.
If the heating element of your LG washing machine is out of order, we advise you to contact the LG Brand Service by leaving a request by phone 8-499-677-76-76 (for calls from Moscow and the Moscow region) or by phone 8-800-200-76- 76 (for calls within Russia). LG Branded Service specialists will quickly and efficiently carry out repairs of any complexity. But if you feel like a jack of all trades and want to take on the troubleshooting yourself, we have prepared for you step-by-step instructions on how to replace the heating element in an LG washing machine.
Replacing heating elements in an LG washing machine: step-by-step instructions
You can replace a faulty heating element in an LG washing machine without resorting to the services of a technician. The vast majority of LG models are direct drive, which means there is no drive belt that could get in the way when replacing the heating element.
How to remove the heating element in an LG washing machine
- Before you start replacing the heating element, make sure that your washing machine is unplugged. Turn off the water and disconnect the inlet and drain hoses.
- In LG washing machines, the heating element is located under the tank, which makes it easy to change the heating element.
- Remove the back panel of the washing machine (usually it is attached with bolts or screws).
- You will see the outer part of the heating element with external contacts at the bottom of the tank wall.
- Remove the wires from the heating element. Before doing this, you can take a photo of their location on your smartphone so that when installing the element in place, you won’t make a mistake.
- Loosen the nut located in the center of the heating element so that it rests on the end of the thread. Press it in along with the pin.
- Now you can get the heating element. This will be easier to do if you carefully pry the part off with a screwdriver or knife. Remember that the surface of the element, contacts and seat are very vulnerable to mechanical damage, so you need to act slowly and carefully.
How to install a heating element in an LG washing machine
- Before you start replacing the element, prepare the seat by clearing it of scale and dirt.
- Lubricate the seat, seal and the element itself with any lubricant for technical parts.
- Carefully place the new heating element into place.
- Screw on the nut and tighten it with a wrench.
- Connect the terminals and wires.
- Assemble the body of the machine, then run the machine without laundry on high temperature mode. You can check whether the new heating element in your LG washing machine is working by touching the glass of the loading hatch after 15 minutes of washing: it should be warm.
In order for a new heating element to last a long time, you need to choose the right part. Carefully study the SMA data sheet and determine the power of the element. For LG washing machines, the figure is usually 1900-1950 Watt, but for some models the power can be 2 kW.
If for some reason you cannot look at the data in the data sheet, then you can find out the information on the heating element itself: markings may be applied to it. It is these values that will help you not make a mistake when purchasing and choose the part that will suit your LG washing machine.
You can buy heating elements at an LG service center, in a specialized spare parts store or in an online store. Experts recommend not purchasing parts second-hand, especially second-hand ones.
Where is the heating element located?
Before you begin work on replacing the heating element, the water is drained from the machine. It is de-energized and only then disconnected from the water supply and sewerage system.
The equipment is deployed so that access to the rear of the machine is ensured, after which the panel is carefully removed.
First you need to determine the location of the TEN. There is no drive belt in LG household appliances, so it will not interfere with the removal of the spiral, but it is better to clarify what structure the machine has before starting work. This information is given in the instructions.
When the back wall is removed, a view of the internal parts will open. The spiral is easy to find; its contacts will be clearly visible. It is located near the barrel. There are many wires connected to it, everything is carefully disconnected.
It is necessary to remember the location of the wires; it is better to draw a diagram.
This stage is important. If the wires are mixed up when connecting, the heater will fail, and the machine may also break down.
We remove the old one
To change the heating element, the old one must be removed. This is done as follows:
- The machine body must be disassembled;
- The drive belt (if any) should be removed so that it does not interfere with operation;
- The wires going to the heater terminals must be disconnected (remembering their location);
- Disconnect the positive wire from the temperature sensor terminal;
- Loosen the central nut fastening the heating element (without unscrewing it completely);
- Push the pin on which the nut sits inside the housing (but carefully so that the heating element does not fall into the tank;
- Using several flathead screwdrivers, remove the heating element, being careful not to damage the washing tub.
Before carrying out the above steps, you should determine where the heater is located. After this, the back or front walls of the machine covering it are removed. In different models, the covers can be attached in different ways, namely, with a different number of bolts.
If the car has a drive belt, then it can be removed using a screwdriver, which should be used to carefully pry it up and then it can be easily pulled out. The main thing is not to scratch the belt, otherwise it will definitely break later.
As for the heating element terminals, there are usually four of them. This is grounding, a wire from the positive terminal of the temperature sensor and two power cables. The first two may not exist, depending on the car model.
Important: be sure to disconnect the washing machine from the electrical power supply for the period of repair work!
When removing the heating element, a situation may arise where it will not be easy to get it out. This can happen due to deformation of the rubber o-ring, which hardens over time and sticks to the edges of the heater. In this case, you should carefully pry it off with a flat screwdriver and, helping with your hand, remove the heating element. If the seal is unsuitable, then it should be changed.
Where to look for the heating element?
LG's home assistant hides the heating element in a standard place for automatic washing machines - right at the bottom of the tank. Finding an electric heater is easy: you just need to turn off the machine from the power supply, turn off the water supply, turn the body 180 degrees and remove the back panel. Pay attention to the bottom of the drum - it is under it that there is a metal part connected to many different wires. You will never confuse it with the engine or other components, because the heating element is always located in the tank, surrounded by wiring.
But while searching for, dismantling and installing a new water heater is not difficult, diagnosing and understanding the causes of the breakdown can be much more difficult. The heater can become unusable due to a number of problems, which is why it is so important to accurately determine the cause of the problem in order to eliminate it and prevent the breakdown of the new heating element. Most often, a part fails for fairly mundane reasons.
- Sudden power surges.
- Incorrect operation of the heater temperature sensor.
- Overheating of the part due to a large layer of scale.
Scale caused by too hard or dirty water can be avoided by using water softeners such as Calgon.
- Banal carelessness of the user during operation.
- Moisture on the contacts of the part.
- Manufacturing defects.
Most often, replacing a damaged part can eliminate the malfunction and return the device to normal operation. But it is much worse if the reason is hidden in the control board, the replacement of which costs users much more. If the electronic control module is damaged, for example, the contacts have come loose and the tracks are damaged, then it will have to be repaired or replaced. And it is not recommended to carry out this procedure yourself, since it is too complicated for people without professional technical education. In this case, it is better to call a service center technician to your home.

What will be needed for replacement?
So, having purchased the necessary part for repairing washing equipment, prepare the tools for its installation. You will need:
- Two screwdrivers - flat and Phillips;
- Spray lubricant to loosen boiled joints (eg WD-40);
- Multimeter;
- Keys and socket heads of the required sizes to remove the back cover (in most cases, a “figure eight” will do).
Prevention
Do not forget about preventive measures regarding the Indesit washing machine. Having replaced the old heating element with a new one, maintenance of the tank will be required in order to remove the dangerous deposits accumulated there. The tank may contain solid impurities in the form of scale. Sometimes undigested fats from things are deposited there (in the form of mucus). This fat gives off an unpleasant odor.
Preventive measures should be carried out periodically, depending on how often you run the wash and at what temperature conditions. So, to prevent the formation of deposits in Indesit machines, it is recommended to do the following.
- A special salt filter will need to be installed in the operating water supply gap. This must be a high-quality softener, which will always need to be replaced in a timely manner.
- For washing, it is recommended to use only high-quality powders and gel compositions - with their use, heating elements and other components of washing machines last much longer.
- Do not forget to carry out periodic preventative maintenance on your appliances against scale by using specialized products sold in many retail outlets. People often use folk remedies, such as vinegar or citric acid, which easily remove excess fat deposits and scale. But we must take into account that no one can say for sure how these chemical compositions can affect the condition of the rubber elements and seals of the machine.
- Do not overdo it with too frequent wash cycles using high temperature water. Detergents produced by modern manufacturers can effectively combat most contaminants at low temperatures. Thus, washing clothes is more gentle and gentle.
- You should always keep the condition of your household appliances under control. Of course, many users do not delve into possible problems and think about them only when they encounter them. It is advisable to check from time to time whether all components of the unit are working properly and whether there are any malfunctions.
See below for a master class on replacing the heating element.
Voltage drops
A sharp surge in voltage during the washing process can lead to the heater simply burning out, then in any case the owner will have a question about how to change the lg heater in the washing machine, and most importantly, can you do it yourself? The answer is obvious, without special skills and appropriate education, it is impossible, and besides, you will need a certain tool. Again we come to the conclusion that we cannot do without the help of qualified LG service specialists.
This outcome can be avoided; to do this, it is advisable to install a separate outlet for the machine, which will be powered from an individual differential machine.
