What to do if the washing machine does not heat water

The appearance of washing machines has greatly simplified the life of any hostess. But, like any other household appliances, these miracle devices tend to break. Appeal to professional craftsmen is not always affordable, and then the problem arises: what to do if the washing machine does not heat the water when washing.

Identify the problem

Before you panic and try to solve a problem, you need to know if there is a problem at all. First of all, you need to pay attention on the selected mode washing. Some brands of cars, for example, Indesit or Samsung do not heat the water during delicate modes, washing silk or sports shoes.

If the mode involves heating, then you need to pay attention, and whether it is set correctly.

Certain models of cars, for example LG, have two regulators to set the mode and temperature. The data of these regulators must strictly comply with the program specified in the instructions. If the specified temperature does not correspond to the regime, then the machine simply does not heat the water. All data is listed in the instructions, so you need to read it very carefully.

If the selected temperature and mode match each other, and the unit has to heat the water, then you should check whether it really does not. Some people think that cool laundry at the end of the wash is a signal of the device's failure to heat the water, but this is not so. The fact is that the rinsing, which is performed by the machine after the washing itself, occurs only in cold water, therefore the laundry can be cold.

Whether or not a washing machine doesn’t properly heat water can be found out as follows:

1. Run the wash at a temperature of about 60 degrees (this is enough, although you can choose any other mode with warm water).
2. After 20-30 minutes, touch the drum glass with your hand.
3. If the glass is still cold, then the water in the washing machine really does not heat up.

It should be noted that the glass must be touched very carefully, you can get burned with heated glass.

If the problem of lack of water heating during washing exists, then the next step is to search for the location of the fault.

Possible places of problem localization

Some cars, especially models with automatic self-diagnosis, if they do not heat the water, they immediately refuse to work. Whereas their more responsible brothers continue to fulfill their main function - washing clothes, but in cold water.

If the machine that does not heat the water still continues to be washed, this does not at all mean that the problem should not be solved.

The fact is that such her wrong work can lead to more serious damage. Incorrect operation of the device may be the result of damage to some parts:

1. Sensor failuresthat monitors the water level (then the machine believes that there is still not enough water and it is too early to heat it).
2. Damaged wiresleading to the heating element (the circuit is not closed, the heating element does not work).
3. Breakdown of himself heating element (The heating element cannot heat water due to its own malfunction).
4. Sensor failurethat monitors the temperature (the device simply does not understand when and to what temperature it needs to heat the contents).
5. Breakdown in the control module node (part of the "brain" of the device does not know what to do).

Each of these faults explains why the washing machine cannot heat water, and the laundry is not washed.

Causes of failure

The reasons for the breakage of these parts and the results of why the washing machine does not heat the contents can be as follows:

1. Tube clogging water level sensor (this can easily occur due to hairs falling into the machine, debris and pieces of thread from clothes).

2. Rubbing wires due to vibrations during operation of the washing machine (in some models, the internal wires rub against the wall of the washing machine and when it rattles during operation, they are ground).
3. Scum may interfere with the normal operation of the heating element or temperature sensor (sometimes plaque may simply interfere with heat transfer).
4. Power surges in the electrical circuit (they can lead to burnout of the elements).
5. Manufacturing defect (most often is the cause of failure of the control module).

Problem diagnosis

If the washing machine can not heat the water, then you need to diagnose those parts, the failure of which prevents the heating of water. The diagnosis includes a visual inspection or the following actions aimed at identifying the problem:

1. Inspection tube water level sensor.
2. Visual inspection of internal wiring.
3. Visual inspection of heating elements for the presence of scale.
4. Testing the efficiency of the heating element with a multimeter (measure the resistance of the device, heat the heating element and measure the resistance again, compare the values, and if they do not differ much, then the element has blown).
5. Check the temperature sensor (check the operation of the machine with forced heating, if such a function is available).

Debugg

After identifying a malfunction, as a result of which the washing machine does not heat the water, it is necessary to eliminate it. You can do this as follows:

1. Clean or replace the water level sensor tube.
2. Replace or solder and isolate damaged wires.
3. Remove scale from the heating element by boiling it in water with citric acid.
4. Replace the heater with a new one.
5. Replace the thermal sensor.
6. Replace or repair the control module.

It is better to entrust the replacement of the control module to professionals, and in some cases simply to purchase a new device, since the replacement procedure may cost more.

If the washing machine does not heat the water, you need to find the cause of the malfunction of the equipment and try to eliminate it. In case of difficulties, it is better to contact the repairman. And if the washing machine is under warranty, then contacting the service center is obligatory without trying to fix the problem yourself.
