Why does the washing machine wash non-stop

When the machine has been washing without stopping for 2-3 hours, instead of the 60 minutes provided by the program, this is a clear sign of a malfunction. What to do in this case? How to stop the operation of the machine, where to start diagnosing, and what internal nodes can provoke a malfunction? Let's take a look at the nuances.

What happened to the machine?

An automatic washing machine is a complex device consisting of many mechanisms. Over time, components wear out, so the regular operation of the equipment is disrupted. Only sometimes, the time factor leads to breakage. In some cases, the rapid failure of equipment is due to improper connection of the washer or violation by the user of the operating rules.

If the washing machine takes longer than expected, the following problems may occur:

• Problems with the water supply to the tank (the filter mesh, the inlet hose, the dispenser nozzles become clogged, the pressure in the water pipe decreases, etc.),
• The drain hose is connected incorrectly,
• There is a blockage in the drain system,
• The water level sensor is out of order,
• The pump burned out,
• The heating element or temperature sensor does not function correctly,
• Failure of the main control module.

You can fix most problems on your own without the help of a wizard. The main task is to identify the cause of violations in the operation of the washer. Then, when you are done diagnosing, start fixing the problem.

Slow set of water.

The machine often erases longer than usual because water is poured into the tank too slowly. This can lengthen the cycle by several hours. In this situation, you will have to check what pressure is in the water supply system, whether the filter mesh, powder receiver, inlet hose and pipes are clogged, and whether the inlet valve is working.

You can check the water pressure by opening the faucet in the bathroom. If the jet is strong, inspect the shut-off valve. It is possibly not completely open, so the machine's tank fills slowly.

Clogged or incorrectly positioned drain hose.

The next group of reasons are problems in the drain system. If the drain hose is connected incorrectly, the water will leave the machine by gravity and then be drawn back into the tank - due to this. The cycle will lengthen. The groove should connect according to the rules. Then it can cope with the constant liquid circulation in the washer.

In this case, it is easy to repair yourself. All that is needed is to connect the drain hose according to the instructions. The hose must be located under a certain bend and organized at the point of inclusion in the sewer at 40-80 cm above the floor.

If the washing machine freezes while rinsing or spinning, water outflow from the system is likely difficult. In this situation, you must check the garbage filter, the pipe connecting the tank and the pump, the drain hose, and the pump snail for clogging. Probably, it was the common house riser that clogged up - then will require the help of a plumber.

Also, an automatic machine may freeze due to a failed drain pump. If the pump burns out, it must replace. Repairing this part could be more practical.

Level sensor or heating element

If the pressure switch fails, the washing machine will constantly draw and drain water. A faulty sensor does not notify the control module that the tank fills to the correct level. As a result, too much liquid collects, the protection trigger, and some water drains. Then creates a continuous water cycle.

The level sensor is located under the top panel of the washer. Checking the element is simple - unhook the pressure switch tube and blow into it. If there are clicks, the device is working properly. Otherwise, the part will need to replace.

Why the washing time increases when the heating element fails is understandable. The heating element brings the water to the desired degree for a long time. And if the program involves heating up to 90 ° C, you can wait until the cycle end at least all day.

Water heating may not be carried out because:

• The heating element burned out (in this case, the device will freeze at the beginning of the cycle without even starting to spin the drum).
• The surface of the element is covered with a thick layer of scale.

Scale is a separate trouble of washing machines. Tap water contains a lot of impurities - these particles settle on the internal parts of the washing machine. If you do not periodically clean the equipment with special means, the layer of limescale will grow. Because of this, the thermal conductivity of the heating element will be disturbed, and the device will not be able to bring the water in the tank to a predetermined degree.

A faulty temperature sensor can also lengthen the wash cycle. This is because it will need to send correct information about the degree of water heating to the electronic module. Therefore, it may delay the execution of the program for several hours until the self-diagnosis system detects an error.

The do-it-yourself repair will consist in replacing the heating element or thermistor. The parts are located behind the rear wall of the case, under the tank. Before proceeding with disassembly, be sure to turn off the power to the machine.

Electronic board

This problem is considered the most serious. It will take a lot of work to fix it yourself. In this case, it is better to invite a service center specialist to repair the home assistant. If the electronic control module breaks down, the machine can continue washing indefinitely. The device itself will switch programs, freeze and resume work again.

You can fix the problem by flashing the electronic module or replacing the semiconductors on the board. Diagnostics of the microprocessor are performed using special devices and tools. With the necessary knowledge and experience, it's worth getting into the brain of the washer. But, unfortunately, you can only aggravate the situation.

Self-diagnosis system

Today, the process of diagnosing washing machines is greatly simplified. Most modern automatic machines are able to independently detect errors that have occurred in the system. The user will only have to decipher the fault code displayed on display and take measures to eliminate the problem.

For example, in case of a malfunction in the drain system, Indesit models will display the code F-05. Error F-04 will notify you of the failure of the pressure switch. LG machines with the designation PE will inform you that the rate of filling the tank with water differs from the norm - either the required volume of liquid was filled in too quickly or, conversely, slowly.

Marking errors for each model of the automatic machine will be different. A complete list of fault codes is provided in the user manual. The instructions will help narrow the possible problems and identify the problem faster.

Is it worth it to call the mechanic?

What to do when you find a machine that will not complete the program? First, it is necessary to pause the cycle and drain the water from the tank by selecting the appropriate mode with the programmer. After that, you can remove things from the drum and start troubleshooting.

Most problems can be dealt with on your own. For example, clean blockages in the drain system, replace the heating element or thermistor and install a new level sensor or inlet solenoid valve. Work is carried out at home. The main thing is to follow the safety rules.

Another thing is if the control module is out of order. In this situation, diagnosis and repair should be entrusted to specialists. Without experience with electronics, you can damage the washer even more, and then you will have to change the entire unit, which is very expensive.
