Why does the LG washing machine not heat the water? How can I find the problem and fix it?
To carry out high-quality washing, in most cases, you need not only good detergents and mechanical action, but also good water heating.
If the device malfunctions, when heating does not occur, effective washing in most modes will not be performed.
To restore the normal functionality of the LG washing machine, it is necessary to carry out diagnostics and repairs. We will discuss below what are the reasons why the LG washing machine does not heat the water when washing.

Reasons why the water does not heat up when washing
Cause a malfunction of the LG washing machine, in which the water does not heat up, there could be a number of reasons:
- wear and tear of equipment during long-term operation;
- poor quality water;
- unsuitable detergent;
- power surges;
- water getting inside the washing machine body, including the control unit.
Diagnosis and solution of the problem
Faced with the problem of lack of water heating during the washing process, it is necessary to analyze the condition of the device and the performance of the components that are involved in the process.
How to make sure there is no heating?
When it seems that the water was not heated when washing your LG, you should make sure that this is really the case. The fact that the things that are taken out of the washing machine drum after processing are cold does not mean anything, since after washing the laundry is rinsed in cold water.
If you are in doubt about the degree of water heating necessary:
Make sure that the water heating mode is selected. Some programs run either without heating at all or heat the water slightly, for example, when processing in the “wool” mode.- During the washing process, the machine begins to heat the water gradually. On average, 10-15 minutes after startup, you can check whether heating has started. This can be done by carefully touching the glass of the hatch.
Modern models of LG washing machines, if the heating specified by the program does not occur, in most cases stops washing and displays an error code indicating a failure.
Draining and adding water
Washing machines can go wrong in any way. If you have any doubts about the quality of the wash and the water heating process, this point should be monitored. When operating correctly, the machine draws water and begins washing, gradually heating the water.
But when a failure occurs, then a situation with spontaneous discharge of water and its constant topping up is possible. In this case, the process simply does not reach the start of heating, so the heating element does not even turn on.
In such a situation, you should stop the program, drain the water and take a closer look at why the water is being dumped. This could be a leak, a malfunction in the installation of the drain filter when installing the washing machine, etc.
Heating element failure
Failure of the heating element is not such a rare case. The reason for the breakdown of the LG machine can be:
- poor quality tap water;
- using unsuitable detergents;
- foreign objects getting into the drum, and from it into the tank;
- development of service life.
In order to determine the condition of the heating element, it is necessary to gain access to it. This is done from the back wall of the washing machine.
The heating element should be removed carefully so as not to damage the tank and “socket”, in which the heating element is placed.
How to replace the heating element in an LG washing machine can be seen in the video:
Failure of the pressure switch
If the temperature sensor breaks down, the washing machine is unable to determine that the indicator does not reach the required value and there is no heating. If the pressure switch is broken, it is replaced with a new part. The sensor is not repaired.
Control module malfunction
Damage to the control module may be due to voltage surges, moisture or mechanical damage. In the case when the block that is responsible for issuing the command to the heating element to produce heating breaks down, the program crashes.
Possible problems
In the process of independently repairing an LG washing machine, you can encounter some difficulties and difficult situations:
| Problem | Solution |
| The heating element cannot be removed from the washing machine | You should check whether the screw that holds the part in place is unscrewed. There is no need to panic - the part comes out quite tightly, and this is normal |
| There are doubts about the performance of the heating element | You can check the functionality of the unit using a multimeter |
| The new heating element does not fit | Perhaps the part does not match the washing machine model, this point should be checked |
| You should check whether debris from the tank is interfering with the installation. | |
| After replacing the heating element, the machine began to leak | The new part may not have been installed correctly. |
| The heating element is not suitable for a specific SMA model | |
| After replacing the heating element, water heating was not restored | A worn heating element may not be the only problem. It may be worth turning to professionals for help in diagnosing the condition of the machine. |
| You should check that all contacts are connected correctly |
