Why the washing machine does not heat water, troubleshooting

One of the most common problems with a washing machine is that it does not heat water. It is impossible to wash clothes well in cold water, and calling a master to fix it is too expensive. There are several reasons why your washing machine does not heat water, and some of them can be eliminated on your own.

Why the washing machine does not heat water, if it is working?

Previously, all clothes were washed by hand, which caused great difficulties and took a lot of time. Now this problem is fixed by washing machines: but no one is safe from breakdowns. And in cold water, even the most modern washing machine is not capable of qualitatively washing things. Not only a good washing gel affects the process, but also the temperature. Those who had to wash in cold water know this firsthand.

The minimum temperature of water, which is set for high-quality washing - 30 degrees

Unfortunately, dirty tap water is often damage to the washing machine. What to do if there is a malfunction in the washing machine and the water does not heat up:

1. Check if this is true. The laundry that is removed from the washing machine after washing is cold. And this is not an indicator that it was washed in cold water. New models of washing machines, as a rule, stop washing after 10-15 minutes and an error code is displayed. Older washing machines tend to go through a full cold wash cycle. To find out, you need to gently touch the glass of the hatch 20 minutes after starting the program. If it is cold, then the problem is obvious;
2. Check the selected mode. There are automatic washing machines that choose the temperature themselves. Perhaps the device has chosen a mode of 30 degrees for delicate fabrics. If a higher temperature is required, you only need to change the mode;
3. Check machine connection. If the machine is not connected correctly, then the water in it constantly circulates and quickly cools. Therefore, it is worth checking whether it is connected correctly.

If the above problems are resolved, but the washing machine still does not heat up, then it needs repair. There are three main reasons why the water in the washing machine remains cold.

Troubleshooting

The most popular models of washing machines: Samsung, Bosch, Ariston, Candy, Indesit. Most people use them, so the main problems are considered on their example:

The cause of the breakdown may be overheating of the heater.

If the washing machine does not heat the water, then the failure of the heating element is the most common reason. The heater is an electric heater, which is precisely responsible for heating the water. There can be many reasons: short circuit, voltage drops, age of the washing machine. TEN serves no more than five years, after which it must be changed.

Due to the fact that the heater is constantly in the water, scale forms on it. If no other faults are found, and the heater is completely covered with scale, it should be cleaned. To do this, add citric acid to water and boil. In order to avoid further scaling, you should regularly clean it with descaling agents or drive lemon water in the washing machine. In order to get clean water into the machine, you can install a filter.

If the scale is removed and the water is still cold, there may be a problem in open circuit. In order to check this, you need to remove the bottom wall of the machine and check the integrity of the wires. If the wires are broken, they can be replaced with new ones. The combustion of the heater itself may occur.

Self replacement of TEN

New TEN washing machine

It is necessary to remove the old heater, insert a new one into the landing hole in the washing machine. It is important to remember in what position the old electric heater stood and install the new one in exactly the same way. Next, a nut is installed on the stud and tightened with a wrench. After that, you can connect the wires and put the wall of the machine back.

You can call the wizard for this work, but the independent installation of the heater will take a minimum of time and effort. After installation, start the wash at a low temperature. After 15 minutes, check the hatch for temperature.

Temperature sensor failure

The location of the thermostat depends on the model of the machine. It is located either in the electric heater itself or on the surface of the tank. The thermostat monitors the temperature of the water and gives signals about heating if necessary.

The thermostat is equipped with a special sensor, which ensures timely heating of water and its cooling. If this sensor is defective, then the water cannot be heated. Check the sensor status as follows:

• Remove it from the washing machine and check the resistance with a multimeter;
• Put in hot water and repeat the procedure;
• If the results of measurements in the hot and cold state do not differ much from each other, then the thermostat must be replaced.

Sensor check with a multimeter

To replace the temperature sensor, it is better to contact the master, as this is not an easy procedure. But, with certain skills, you can do it yourself. It should be remembered that the sensors in the washing machine are of different types.

Replacement of different temperature sensors:

• • Gas-filled sensor. It is a metal empty washer with a diameter of 3 centimeters. Located at the bottom of the tank. The part responsible for measuring the temperature of the water is located in the tank itself. The external part is a thin tube that connects the internal to the temperature controller. There is gas in the washer which is responsible for regulating the temperature of the water. Compressing, it delivers the desired signal to the sensor.

• To fix the problem, you need to carefully remove the broken sensor without damaging the attached tube. The tube is disconnected from the wires and the regulator. The new sensor is inserted exactly the opposite. Attached to the tube, connected to the wires and fixed in the tank. To make the sensor stand denser, it is better to fix it with superglue;

• Bimetal sensor. Externally, this device is similar to the previous one, but the difference is as follows: it contains not gas, but a bimetallic plate. The plate is responsible for controlling the water: the contacts close at a certain temperature - heating stops, and vice versa.
  

  Bimetal sensor

• The sensor must be carefully removed from the tank and the wires disconnected. Lubricate the new sensor with superglue for greater strength;
• Thermistor Most often found in modern models of washing machines. It has a cylindrical shape and a length of about 3 centimeters. The mechanism of operation is simple: the electrical resistance decreases several times during heating, and the thermistor itself controls the temperature of the water.
  

  Thermistor

• To replace it, remove all water, loosen the fixed heater, disconnect the wires and remove the mechanism. To install a new thermistor, you need to connect the wires, fix the electric heater and insert a new mechanism. Additional fastening is not necessary.

Programmer failure

If the heater is in order, the temperature sensor is fixed and the washing machine is connected correctly, then the matter is most likely in the programmer itself.The programmer controls all programs and modes, is the "brain" of the washing machine.

The causes of failure can be different: as a rule, this is careless handling of the device. It happens enough that a small child during the washing process starts to press buttons and turn the knob. In this case, the machine can easily fail.

Children's pranks can lead to breakdown of the programmer

If the programmer broke after a recent purchase of a washing machine, then the cause may be a factory defect. Power surges and water getting into the programmer are not excluded.

In washing machines such as Samsung or Bosch, the programmer has a fairly simple mechanism and, if desired, you can fix it yourself.

Fix the Ariston washing machine programmer:

• Take the removed faulty programmer and carefully inspect it. Pry tabs on the side of the cover and remove it;
• Carefully get the board under the cover and put it aside;
• Carefully remove the gears and check for dust or dirt. It happens that cleaning gears is enough for the programmer to work properly;
• Inspect the board. If there is a burn, then carefully solder them again;
• Check the resistance on the contacts and fix the problems, if any;
• Finally disassemble the mechanism and inspect all the details for their integrity. In case of detection of defective parts - replace;
• Assemble the programmer in the reverse order.

The washing machine heats water for a long time

There are situations when water in a washing machine does not warm for a long time. In this case, often the owners do not pay attention to the problem. And very in vain. If the washing machine heats the water for a long time, this may result in damage to the electric heater or temperature sensor. If such a problem is detected, it is best to fix it immediately.

As a rule, a long heating of water occurs due to a thick layer of scale. Water from the water supply system is very dirty, and scale is a common occurrence.

The cause of the malfunction may be a large layer of scale on the heating element

In order to get rid of scale in the washing machine, it is necessary to pour 1-2 tablespoons of citric acid into the powder compartment and put the longest regimen with the maximum temperature. Rinse the powder compartment after washing.

These are the main reasons why the washing machine does not heat water. They can be eliminated independently, being careful. However, if the problem of failure is different, it is recommended to call the wizard. The master will evaluate the condition of the machine and qualitatively fix the problem, without any subsequent difficulties.
