Why does the LG washing machine not heat when washing?

It is impossible to list all the possible breakdowns that occur during the operation of washing machines. However, some of them are so obvious and so hinder the full operation of the unit, that many housewives dream of learning how to fix them on their own. So, for example, the question is urgent: what to do if the LG washing machine does not heat water.

Is there a breakdown?

Yes, it happens that the alarm turns out to be false. It seems that everything is obvious: the washer does not heat water, although it should. First, check if you set the temperature that matches the selected washing process. If the unit detects a mismatch, it will not be able to give a command to the module, and heating will not start. If you doubt the correctness of the degrees set, look in the user manual.

Water heating is not carried out the same way with gentle washing modes. Delicate fabrics do not tolerate high temperatures. To find out which program with which temperature erases, look in the instructions. It is possible to find out for sure whether a malfunction exists in the following way:

• select and run a program that provides for washing in hot water (40-60 degrees, as a rule);
• after about half an hour from the start of washing, touch the glass of the hatch door with your hand, if it remains cold, it means that the heater did not warm up during washing.

Important! The problem with heating does not necessarily arise due to the heater; therefore, before taking any action, it is necessary to accurately localize the problem.

What part could break?

Cars with a built-in self-diagnosis system at the slightest problem refuse to work until all the problems have been fixed. Less perfect models continue to wash, as if nothing had happened, even in the absence of heating. But you need to resolve the situation anyway. Whether you will do it yourself or call the master, you decide, but you need to do it. Failures in the operation of the unit can be caused by the breakdown of a number of elements.

• Water level sensor. It gives the water heater in the machine a signal to heat the water after it has accumulated enough volume. Since the element is defective, the signal is not given, and the heater is not activated.
• Contacts connecting the heater with other parts.
• Directly the heater itself, not performing its functions due to a malfunction.
• The sensor that controls the degree mode. Since the machine does not understand at what temperature it is necessary to heat the water, it prefers to leave it cold in order to avoid more serious dysfunctions.
• The corresponding chip in the management board. The unit becomes completely disoriented with regard to heating water.

These problems require immediate intervention, since washing in cold water will not work for a long time, some fabrics simply do not wash at low temperatures. In addition, all the elements of the washing machine are interconnected, so one malfunction may soon lead to others.

Why did the machine fail?

In turn, the above breakdowns also have their own reasons. Some of them are understandable and logical.

1. The water level sensor tube is clogged. After washing in the machine inevitably there are specks, hair, villi, which create congestion.
2. The wires are frayed. Not all models have a perfect electronic device. For some machines, the wires are laid along the walls of the housing, and due to vibrations during the washing or spinning processes, the wires are frayed.
3. TEN stuck with scale and limescale. In the worst case, the heater in such a bag overheated and burned out, at best - the heat simply does not pass through the layer covering the part.
4. A manufacturing defect that caused the control module to fail for no reason.
5. Power surges in the network, due to which one of the elements could burn out.

In the case of manufacturing defects with an unexpired warranty period, the user can count on free repair or replacement of the washing machine in the technical center. But this is if the warranty card was issued properly. If there is no heating in the machine, you can’t leave everything as is, it is necessary to solve the problem as quickly as possible.
