Today, washing machines are a common feature in apartments and private houses. Bosch washing machines are very popular, since they are made from high-quality materials using modern technologies. But even such cars can fail over time. This article will show you how to repair your Bosch washing machine with your own hands.

Modern Bosch washing machines contain a special program that allows you to identify faults without asking for help from a master.

The operating instructions for your Bosch washing machine should contain information on how to perform this diagnosis. If the drum has stopped rotating, then you must perform the following sequence of actions:

1. Close the door;
2. Set the program selection knob to the "Off" position;
3. Wait a couple of seconds;
4. The spin handle should be set to the “Spin” position;
5. Then wait until the "Start" button starts blinking;
6. Hold the "Spin RPM" button pressed;
7. Wait until the "Start" button flashes again;
8. Set the handle to the "Drain" mode;
9. Release the button "Spin revolutions";
10. Determine the last breakdown by the error code for the Bosch washing machine.

The program clears the last error from memory and runs diagnostics. To check the electric motor, set the mode selector knob to position 3.

To check the drain pump, set the knob to position 4. You can check the heating element by setting position 5. Diagnostics of the hot or cold water inlet valves is carried out by selecting positions 6 and 7. When position 8 is selected, the water inlet valve is tested during the main wash, and 9 - preliminary washing.

According to the technicians of Bosch service centers, the following breakdowns are most common:

• Water does not heat up during washing;
• Water does not drain;
• The drum does not rotate;
• The drum of the washing machine makes a noise;
• Water is not collected;
• The electric motor will not start.

When analyzing the malfunctions, one can come to the conclusion that in washing machines Bosch most often comes out of the standing heating element. If the heating element is broken and the electronic system is working properly, then the repair will not take much time.

However, if the electronic system is also out of order, then the repair will be quite expensive. After all, you will have to replace the electronic modules and call the master.

There are a number of reasons why a Bosch washing machine can fail. Let's consider them in turn.

She may not drain the water at the end of the wash cycle for one of the following reasons:

• Clogged pump or drain filter;
• Poor contact between power supply and pump;
• Drain pump defective;
• The water level sensor is broken.

The drum stoppage can occur for the following reasons:

• The drive belt is worn out;
• Malfunction of the control board or electronics;
• Failure of the electric motor (rare case).

The drum may make noise during operation. This may be due to the following reasons:

• Bearings came out of standing;
• Small items are stuck in the drum;
• The shock absorber has broken;
• Counterweight problems.

It is possible that no water is drawn into the tank. In this case, the following reasons are distinguished:

• Clogged Aquastop system or pump;
• Lack of water in the plumbing;
• Hall of the drain hose.

If the electric motor does not start, then, most likely, the door of the drum hatch is not closed or the electronics are out of order. After finding the cause of the malfunction, you can proceed with the repair.

The drain filter is located at the bottom of the machine, under a cover or panel. To clean the filter - open the cover. To do this, turn it counterclockwise. Filter - rinse and reinstall.

To clean or replace the drain pump, you must remove the front cover of your Bosch washing machine. This work is laborious, but not difficult.

Quite often, there is a malfunction in which water is not drawn into the Bosch washing machine. In this case, it is necessary to check the water supply and the water supply valve. They can be closed. Next, check if there are any kinks on the drain hose. If everything is in order, check the condition of Aquastop. If this element of the Bosch washing machine is out of order, it should be replaced with a new one.

If the water level sensor breaks down, it must be replaced. To do this, first dismantle the top cover by unscrewing the two self-tapping screws located at the back. This sensor should be located in the right corner under the cover. To pull out the water level sensor, you need to push down on the latch. Next, remove the hose and disconnect the contacts. Instead of the old sensor, a new one is mounted.

You can replace the heating element of your Bosch washing machine yourself. To do this, you need to remove the back cover of the Bosch washing machine. The heating element is located below, under the tank. To replace the heating element, proceed as follows:

• Unscrew the bolt that secures the heating element to the tank.
• Disconnect the wires;
• Dismantle the heating element;
• Install a new heating element and carry out all the steps in reverse order.

Replacing bearings on Bosch washing equipment is a rather difficult task, since for this you will need to disassemble almost the entire washing machine. Watch a video on how to replace bearings:

Stopping the motor can cause wear on the drive belt. You can replace this element yourself. To do this, you need to perform the following sequence of actions:

1. Open the back cover of the Bosch washing machine;
2. Remember how the belt is attached to the grooves of the pulley. Better to photograph this element.
3. Take the belt just below the pulley and gently pull it towards you.
4. With your free hand, turn the pulley counterclockwise.
5. Pull the old belt out of the washer body.
6. Put a new belt on the motor of the Bosch washing machine.
7. Tighten the belt with one hand and try to slide the drive belt onto the pulley with the other.
8. Turn the pulley counterclockwise without loosening the belt. In this case, you must try to put on the belt completely.
9. Install the housing cover of the Bosch washing machine.

Drum noise can be caused by worn shock absorbers, bearings, and torn off counterweight.

Before replacing the shock absorbers, you need to carefully examine the drum of the Bosch washing machine using a flashlight. There is probably a small object stuck in it, which makes a noise when the drum rotates. You can learn how to replace shock absorbers in a washing machine from the following video:

Loose counterweights, which are located at the bottom of the Bosch washing machine and under the top cover, can also cause noise. To eliminate this malfunction, you need to tighten the counterweight fasteners.

If it is not possible to fix the counterweight, then it is recommended to replace it with a similar one. This failure is quite rare.

There are two ways to fix this problem. The essence of the first method is that the electric motor of the Bosch washing machine must be removed and given to the craftsmen for repair. They may be able to fix the problem. If the engine cannot be repaired, then it will need to be replaced. Such a replacement will be quite expensive.

In order to get to the motor of the Bosch washing machine, you need to remove the back wall of the washing machine. The engine is located under the tank. First you need to disconnect the wires and the sensor from the motor. Secure the motor with three fasteners. They must be unscrewed. Experts advise to check the condition of the sensor condensate before removing the motor. For these purposes, you will need a multimeter. It is necessary to connect the probes of the device to the contacts and look at its indicators. The multimeter should read 20-50 ohms.

If you suspect that the wiring is faulty, you must check all terminals, contacts and plugs.

If the control unit fails, you need to call the wizard or dismantle the part and take it to the Bosch service center. You should not try to repair the electronics of German technology. After all, to do such work, you need to know many subtleties.

One of the most popular series of Bosch washing machines in recent years has become the MAKS-4 series, which includes front-loading machines with a cabinet depth of 40 cm. Unlike its full-size "sisters" - washing machines of the MAXX series with a cabinet depth of 60 cm and a load of 6 kg of linen, - machines of the MAKS-4 series are designed for a load of 4 kg of dry linen.

The machines of this series have an electronic control system Fuzzy Logic, with the help of which the imbalance of the laundry and the price formation in the drum are monitored, as well as the control of the water consumption and rinsing time in accordance with the load of the laundry.

The control panel of the MAKS-4 series washing machines is equipped with rotary knobs for selecting the washing program (preliminary, intensive, delicate, hand wash of wool, etc.), buttons for selecting additional functions "Easy to iron", "More water", "Quick wash "And LEDs indicating the progress of the program (from top to bottom:" readiness "," work "and" end of work "). In fig. 1 shows the control panel of the Bosch WFC 2060 BY washing machine (according to the company's new designation system - model B1WTV3002).

On the control panel of this model there is also a knob for selecting the speed of rotation of the drum during spinning (from 600 to 1000 rpm).

Using the program selector knob, the mode is set according to the type of laundry and the degree of soiling. So, for cotton and strongly dyed colored fabrics, you can set the wash mode at 90 ° C without prewash or with a prewash at 60 ° C. For lightly soiled laundry or for fragile colored fabrics, you can select a wash cycle at a temperature between 30 and 60 ° C (the so-called EASY CARE mode or Pflegeleicht mode).

When you select the additional function "Easy to iron", the spinning of the laundry occurs at intervals, the duration of which is determined in accordance with the set washing program.

Thanks to this spin mode, the number of creases on the laundry is reduced, which makes it easier to iron.

Another model of this family - the Bosch WFC 1600 BY washing machine (according to the new designation system of the company - model B1WTV3800A) - does not have a knob for adjusting the drum rotation speed during spinning, instead there is an additional button for selecting the rotation speed - 800 or 600 rpm. Instead of the “Easy to iron” function, there is a “Forced spin off” function, also activated using a button.

This model of washing machine has energy efficiency class A, washing efficiency class A, spin efficiency class D. When washing colored laundry at a temperature of 60 ° C, water consumption is 49 liters, electricity consumption is 0.8 kWh, washing time is 90 minutes. ... The machines are equipped with the Aqua-Spar system, thanks to which the laundry is quickly and efficiently moistened.

In fig. 2 - 5 show the structural elements of the WFC 1600 BY washing machine (control panel, housing elements, tank, drum and main electrical components, hydraulic system), and in table. 1-4 lists the corresponding components.

Household appliances from Bosch have earned the love of customers for their quality. German-assembled washing machines evoke admiration, ranging from the quality of the materials used for the production of machines and ending with their ergonomics. However, even among this technique, there are copies of machines that fail. That is why, we decided to write an article on how to repair Bosch washing machines on our own, and whether it is possible to do it.

Modern models of machines from Bosch are equipped with a special program that allows you to identify equipment malfunctions without contacting the master. The instruction manual will probably tell you how to make such a diagnosis correctly. If not, then we offer a detailed algorithm for testing machines, in the case when the drum has stopped rotating:

1. Close the drum door of the machine.
2. We put the program selection knob to the "Off" position.
3. We are waiting for 2-3 seconds.
4. Now turn the knob to spin mode.
5. We are waiting until the "Start" button on the machine's control panel flashes.
6. Hold down the "Spin speed" button.
7. We are waiting until the "Start" button flashes again.
8. We turn the knob to the "Drain" mode.
   Important! You need to rotate the handle clockwise.
9. We release the button "Spin revolutions".
10. By the error code of the Bosch machine, we determine the last malfunction.

For your information! If the washing machine diagnostics did not start at all, then there is a malfunction in the system board.

In addition, the program provides for deleting the last error from memory and starting diagnostics of faulty elements. To start the engine check, you need to set the mode selector knob to position 3. When the knob is set to position 4, the drain pump will be checked, and in position 5 - by the heating element. Positions 6 and 7 are intended for diagnostics of hot or cold water inlet valves, in position 8, testing of the water inlet valve will start during the main wash, 9 - preliminary.

The masters of Bosch service centers found that of all possible breakdowns of washing machines, the following malfunctions are most often encountered in Bosch machines:

1. The water does not heat up during washing.
2. Water does not drain.
3. The drum does not rotate.
4. Noise inside the drum.
5. No water is drawn.
6. The engine will not start.

Based on this list, we can conclude that in washing machines of this company, the heating element most often burns out. If Teng burned out, and the electronic system remained intact, then the repair will be carried out quickly and safely.Otherwise, you will have to change expensive electronic modules, giving the technician to the master.

What malfunctions can occur in the washing machine, everything is clear. And what can cause a breakdown, you need to find out. Let's deal with everything in order.

If the machine does not drain the water after the wash cycle, this may be due to:

• breakdown of the drain pump (pump);
• clogged drain filter or pump;
• contacts between the pump and the power supply are faulty;
• the water level sensor is out of order.

In the case of stopping the drum, the most important reasons are:

• wear of the drive belt;
• malfunction of the electronics or control board;
• it is very rare that the engine breaks down in such machines.

Drum noise can be caused by:

• faulty bearings;
• a small object stuck in the drum;
• breakage of shock absorbers;
• torn off counterweight.

When water is not collected in the washing machine tank, the following reasons are distinguished:

• lack of running water;
• blockage of the pump or Aqua stop system;
• occurred by the kink of the drain hose.

The engine of the Bosch washing machine may not start due to a breakdown in the electronics or an open drum door... Having found out the cause of the breakdown and its severity, you can start repairing yourself.

If the breakdown is still not determined, we turn to the master.

Now we will describe in detail what malfunctions can be eliminated with our own hands, how to repair a car. Let's start with the simplest thing - a clogged drain filter. It is located at the bottom, under a panel or cover. To rinse it from accumulated debris, you need to open the lid by gently turning it counterclockwise. Be sure to use a large rag to prevent any leftover water from spilling onto the floor. Rinse the filter under running water and reinstall.

Cleaning or replacing the drain pump will not be complete without removing the front cover of the machine. This process is simple, but time consuming. This work is described in detail in the article on how to repair a pump in a washing machine.

With your own hands, you can eliminate the malfunction associated with the fact that water is not collected. First, we check if the water supply is turned off and if the water supply valve is open. Then the drain hose is inspected for kinks, and only then can the Aqua stop filter be checked. If it is not working properly, then it is necessary to replace it with a similar one.

If the water level sensor is broken, it must be replaced. The sensor is located under the top cover in the right corner. To remove the cover, it is enough to unscrew the two self-tapping screws from the back. The sensor itself is pulled out by pressing the latch. Then the hose is removed and the contacts are disconnected. A new one is installed in place of the faulty water level sensor.

How to replace a heating element in case of a breakdown? A similar malfunction can also be eliminated by hand. Opening the back cover of the washing machine, below, under the tub, you can see Teng. To replace it you need:

1. Unscrew the bolt holding the heating element to the tank.
2. Disconnect all wires.
3. We take out the ten.
4. We take a working ten.
5. Putting it all in reverse order.

More difficult is the job of replacing bearings in a Bosch washing machine. After all, you will have to almost completely disassemble the washing machine to get to them. In addition, tools and dexterity are required. A detailed video was filmed about this. All works in it are made by real masters.
