For what reasons the washing machine stopped heating the water and how to fix the breakdown

Modern washing machines do not need hot water. As a rule, the devices independently heat the liquid to a certain temperature, which is provided by the mode. However, from time to time, problems arise that lead to failures during the work cycle. If the washing machine does not heat the water during washing, then the problem may be either a malfunction of individual elements, or an incorrectly selected mode.

Main reasons

There may be several reasons for the appearance of such a violation. Diagnosis of possible violations consists of visual inspection or assessment of the situation using special devices (tester, multimeter). However, in most cases, only a specialist can fix the problem.

Wrong mode or connection

As there are washing peculiarities during some programs, heating problems may occur when manually selecting the temperature mode. For example, washing delicate materials (natural silk, wool, lace, tulle) is accompanied by cold water.

If you choose this mode, the temperature will not exceed 30 degrees.

You should also check the connection of the drain and water supply hoses. If a mistake was made during installation, the liquid simply does not have time to warm up. In this case, you must use the instructions and connect the pipes, according to the manual.

The heating element does not work

If the option with the wrong mode or the wrong connection is excluded, it means that the water does not heat up due to a malfunction of the heating element. During operation, some parts of this electric heater may be damaged.

The washing machine element is not immune to a common problem - scale formation. As a result, the heat transfer is disturbed, which leads to the fact that the washing unit refuses to heat the water. But sometimes also the problem comes from the broken wires that are connected to this part.

The heating element is not energized

The heating element may not heat the water even though it is fully operational. In this case, the problem is that no current is supplied to the electrical element. The wiring is subject to various mechanical damage, as a result of which it frays. During its inspection, it is repaired or the wires are replaced with new ones.

Damaged control module

If the machine washes with cold water, one of the likely reasons is a malfunction of the electronic control module. The programmer is the main "brain" of the home appliance. The fact that some violations have occurred is indicated by signals from lamps on the control panel, cold glass during washing, difficulties in setting the program, as well as overheating of the walls of the machine.

Often the breakdown of the module occurs due to oxidation, burnout of contacts, the appearance of cracks on the tracks or their breakage. In this case, you will have to repair the board or completely replace the module control.

Pressure switch malfunction

This element performs the function of determining the water level in the washing machine. As soon as a sufficient amount of liquid is collected in the device, the circuits are closed and heated. If the pressure information is not received, the required command and the water heater do not appear. The cause of the malfunction is clogging of the tube with fibers, paper particles and other debris.

Broken temperature sensor

The temperature sensor is responsible for the operation of the heating element. Quite often, an excessive buildup of rust and scale becomes the cause of sensor failure. As a rule, this element fails as a result of prolonged use of the washing machine - in most cases the breakdown is noticed in the tenth year of service of the unit. The presence of such a problem is indicated by the supply of slightly warm or too hot water.

Inspection reveals a malfunction of this element. A multimeter is used to check its condition. To do this, the liquid is heated, a thermostat is immersed in it, the resistance is measured and the indicator is correlated to the first measurement. The difference in reading should be significant. Otherwise, the part will need to be replaced.

For example, the resistance of a Samsung car is 12 kOhm. If this indicator remains the same when cold, the sensor will need to be replaced.

TEN recovery

Diagnosis of the problem and restoration of the element is carried out with preliminary disconnection of the device from the electrical network.TEN failure occurs due to excessive load, scale formation, mechanical damage or fluctuations in electrical voltage.

It is not recommended to restore the heating element on your own - this must be done by a specialist. To do this, you need to contact the service center.

Ladder

Due to increased water hardness, poor-quality detergents or non-compliance with the rules for using the washing device, over time the heating element becomes covered with scale, which prevents its normal operation. The presence of such a problem is indicated by an unpleasant odor and cloudy water during washing.

To remove plaque, you will need to put 100 grams of citric acid in the detergent compartment, empty the clothes washing drum and activate the 60 degree washing mode. In an hour and a half, the acid will remove the rust and scale. You can also use another method. To do this, you need to remove the part from the washing unit and immerse it in a solution of citric acid. After three hours, you need to remove the element and wipe it from scale with a soft cloth.

Malfunction

To determine the health of the heating element, you will need to use a special device - a multimeter. In operation, the normal resistance ranges from 24 to 40. The check is carried out as follows:

• the device must be disconnected from the power supply;
• remove the rear cover of the washing machine;
• find the heating element (located at the bottom of the tank, under the drum);
• after removing the wires, measure the resistance with the probes of the multimeter.

If the sensor displays the number 0, this will indicate a short circuit of the heating element. In this case, the blown part will have to be replaced with a new one.For this, the fasteners are removed, the heating element is removed with a screwdriver, and a working material is installed in its place.

broken wire

If the multimeter displays the number 1 or the infinity symbol, this indicates that there is a break in the wiring. Such a violation occurs as a result of mechanical damage or regular vibrations when spinning laundry. Frayed cable wires will need to be soldered and then carefully insulated. However, it is recommended to replace broken wires with new ones, as soldered contacts break again during the spinning or drying process.

If the ECU does not work in the washing machine

All modern washing machines are equipped with an electronic control unit, which is represented by a microcircuit. In some cases, a crash occurs in volatile memory. This problem is solved exclusively by specialists engaged in programming and flashing microcircuits. But breakdowns in the ECU system also occur due to a violation of the integrity of the contacts. To identify and eliminate the cause of the breakdown, you will need the help of a qualified technician.

Replacement of the temperature sensor

If the temperature sensor or thermostat fails, the washing machine either begins to boil water or refuses to heat it completely. The performance of this element is also determined by a multimeter. In the washing device, the temperature sensor is located near the heating element.

The replacement of the thermistor is done as follows:

• open the rear panel of the washing machine;
• disconnect the temperature sensor wiring connector;
• carefully remove the sensor from the seat;
• put a new thermistor in its place and connect the connector to it with wires.

You can replace the part yourself, however, in order to exclude possible malfunctions, it is recommended to seek the services of specialists.

How to repair a pressure switch

If the thermostat is working properly, the possible cause of the breakdown is clogging of the pressure switch. The repair of this item is carried out as follows:

• disconnect the washing machine from the power supply;
• remove the rear wall or the front part with the control panel;
• visually assess the situation and inspect the pressure switch relay;
• remove the clamp and disconnect the tube;
• blow thoroughly and clean it.

It is also recommended to check the tightness of the pressure switch. If cleaning does not correct the situation, part replacement will be required. In order to correctly select a new part from the store, you will need to disassemble the defective element and take it with you. The consultant will help you choose an analogue.

Rules for using a typewriter

Before using the washing machine, it is recommended to carefully study the instructions for its operation. First of all, you need to install the washing equipment correctly so that it does not wobble - this way you can avoid mechanical damage to contacts and wiring. In order not to face the problem of scale formation in the future, it will be necessary to add special agents when washing, which are aimed at softening the water. Also, to avoid plaque on the element, you need to drive an empty typewriter with citric acid from time to time.

In order to protect the washing unit from power surges and avoid system burnout, it is recommended to disconnect it from the power supply immediately after washing.

It is not recommended to wash unwashed wardrobe items in a typewriter. Since threads and fibers will surely fall into the pressure switch tube, which will further cause breakage or clogging.

Blockages will lead to a violation of water heating and poor quality cleaning. It is recommended to install special filters that trap this debris. The rules for operating a washing machine are the same for all units, whether it is an LG or Samsung device. Preventive measures, which are aimed at descaling with the help of special means, extend the life of the parts responsible for heating the liquid in the washing machine.
