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:

Video (click to play).

Close the door;
Set the program selection knob to the "Off" position;
Wait a couple of seconds;
The spin handle should be set to the “Spin” position;
Then wait until the "Start" button starts blinking;
Hold the "Spin RPM" button pressed;
Wait until the "Start" button flashes again;
Set the handle to the "Drain" mode;
Release the button "Spin revolutions";
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 heating element while standing. 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 has 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:

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

Customers have long loved Bosch home appliances for their quality. Washing machines assembled in Germany are admirable: they have excellent ergonomics, and the materials used for assembly are of the highest quality. But this technique can also break. Therefore, users should know how to repair a Bosch Max 5 washing machine with their own hands. We will talk about this in this article.

In modern models of Bosch equipment there is a special program, thanks to which it is possible to identify equipment malfunctions without resorting to the services of a master. Typically, the terms of use contain information on how to use the program. And we will consider the algorithm for testing the machine if the drum stops rotating:

We close the door of the loading hatch.
We translate the program selection knob to the “Off” position.
We expect 2-3 seconds.
We transfer the handle to the “Spin” position.
We are waiting for the start of the blinking of the “Start” button located on the control panel.
Press and hold the "Spin RPM" button.
We are waiting for the second blinking of the “Start” button.
We transfer the handle to the “Drain” mode.
We release the button "Spin revolutions".
The display shows a code identifying the malfunction.

Important! If the diagnostics on the washing machine cannot be started, then the system board is faulty.

To start the engine test, the mode selector knob is set to position “3”. After it is installed in position "4", the drain pump will be checked, and in position "5" - the heating element. Positions “6” and “7” start diagnostics of the hot or cold water inlet valves, positions “8” and “9” - testing the water inlet valve during the main and preliminary washings.

The foremen determined that the following malfunctions can be most often encountered:

Lack of water heating during washing;
Lack of drainage of water;
The drum does not rotate;
The presence of noise inside the drum;
Lack of water intake;
The engine does not start.

Important! Based on this list, we can conclude that the most common problems relate to the heating element. When the heating element burns out, but the electronic system remains intact, it will not take much time and effort to repair the Bosch Max 4 or 5 washing machine with your own hands.

Also find out from a separate publication where Bosch washing machines are assembled.

Each malfunction has its own reasons. Let's take a closer look at them.

If there is no water drain after washing, the reason may be:

Breakdown of the drain pump;
Contact faults between the power supply and the pump;
Clogged drain pump or filter;
Breakage of the water level sensor.

If the drum stops, breakdown may occur due to:

Drive belt wear;
Engine breakdowns;
Malfunctioning electronics or control board.

The lack of a set of water in the tank is due to the fact that:

There is no water in the plumbing;
The pump or Aquastop system is clogged;
The drain hose is kinked.

Noise inside the drum may occur due to:

Defective bearings;
Small object stuck in the drum;
Breakage of shock absorbers;
Torn off counterweight.

Important! The engine may not work due to broken electronics or not closed the hatch door. After finding out the cause of the problems, you can start to eliminate them. In the event that the breakdown could not be determined, it is worth contacting a specialist.

If you decide to repair the Bosch Max 5 washing machine with your own hands, prepare the necessary tools. Let's consider the repair of the simplest faults.

It can be found at the bottom of the machine, under a cover or panel. The lid opens gently in a clockwise direction, the filter is pulled out and washed under running water.

Important! Before repairing the filter, be sure to put a few rags under the machine to absorb water.

You can find this part in the right corner under the top cover. To remove the cover from the back, two screws are unscrewed. To remove the sensor, you need to press the latch. After that, you need to remove the hose and disconnect the contacts. Then you can install a new sensor.

Such a repair of the Bosch Max 4 or 5 washing machine with your own hands is also quite possible to do. The heating element is located below, under the tank. You can see it by getting rid of the back cover. To replace, we perform the following steps:

We unscrew the bolt with which the heating element is attached to the tank.
We disconnect the wires.
We take out the heating element.
We insert a new heating element.
Putting it up in the reverse order.

If you did everything correctly, the "START" light will blink.

Press the "SPIN ROTATION" button and do not remove your finger until the "START" indicator flashes again.

Turn the wheel again, this time stopping it in the "DRAIN" program.

Attention! Rotate the selector to the right only.

After releasing the SPIN ROTATION button, select the object to be tested by turning the wheel. Or determine the breakdown by the error code displayed on the scoreboard.

Important! If the diagnostics do not start, then the problem is in the control board (electronic controller), and in this case you cannot do without calling the wizard.

If you decide to manually check individual parts, turn the selector wheel to select the desired item. Proceed in this way:

Checking the engine: position 3.
4 - for testing the pump.
5 - check the heating element.
6 - hot water intake valve.
7 - cold water intake valve.
8 - water intake valve for the main wash.
9 - valve for intake of preliminary wash water.
10 - sound signals.
11 - FCW autotest.
14-15 - "fast" autotest.

Then press "START" again (in addition to this indicator, "DRAIN" and "SPIN" are also on) to start the program test.

To exit the program test mode, press START and turn the wheel.

To exit Diagnostic Mode, turn the wheel to the OFF or OFF position.

Of the entire huge list of malfunctions of the Bosch washing machine, the most typical for this brand are the following failures:

Water is not heated during washing.
No drain.
The tank is not spinning.
The drum is noisy.
No water intake.
The engine does not work.

Based on the specified list, we come to the conclusion that the most vulnerable point of this brand of washing machines is the heating element. If the thermoelectric heater burns out, but the controller is intact, then repairing a Bosch washing machine does not take much work and effort. Otherwise, the controller needs to be replaced, and it is best to entrust this work to a specialist.

Users learn about certain malfunctions by fault codes (or flashing lights). In CM Bosch, the following error codes usually appear: F01, F16, F29, F31, F34, F36, F40, F61, F63, as well as E02 and E67 and others.

The device of the Bosch washing machine determines both the nature of the breakdowns and the reasons for their occurrence. Let's take a look at what usually causes the crashes.

After washing, there is waste water in the tub. This happens for the following reasons:

Failure of the drain pump (pump).
Clogged filter or pump.
Burned out or oxidized pump contacts.
The pressure switch has broken.

If the drum is dead, it may be due to the following reasons:

The drive belt is damaged.
Electronics malfunction.
Less commonly, the engine crashes.

Broken bearings (you will need to replace the bearing in the Bosch washing machine).
Debris and foreign objects in the tank.
Loose or broken shock absorbers.
Torn off counterweight.

Water does not flow into the drum because:

There is no water in the water supply system, low pressure.
Pump or Aqua-Stop system clogged.
Kink in the drain hose.

Engine breakdown coincides with the following "symptoms":

Having determined what caused the malfunction, and assessing its complexity, you can start self-repairing Bosch washing machines.

If you have not identified a breakdown, and do not know how to repair the washing machine, contact a specialist.

The listed reasons for breakdowns are most typical for the Bosch Classic 5, Bosch Mahh 5, Bosch Max 4, Bosch Maxx 6 models, but other models can fail for the same reasons.

Below we will look at the faults and how to fix them, focusing on the most common faults and the best ways to solve them.

Having determined that the drain pump (pump), drain filter or water level sensor (pressure switch) needs repair, we carry out the repair ourselves - this does not require special knowledge and effort.

To eliminate filter clogging, we act according to the following scheme:

Let's find a drain filter: it is located at the bottom of the washer body, under the front panel (can be reached from below by putting the machine on its side) or behind the door of a small technical hatch.
You need to spread a rag or substitute a container - the remaining waste water will pour out of the hole.
Turning the filter cover to the left, remove it.
We clean the filter and rinse it under the tap.
We put in place. Remember that you MUST NOT run the CM without a filter.

To clean or replace the drain pump (pump), you need to properly remove the front panel; for this you may need instructions for your Bosch washing machine. In principle, nothing complicated, but you need to make an effort.

Remove the detergent drawer.
Unscrew the bolt in the lower right corner.
Remove the bottom panel by unscrewing the bolt near the filter and the bolts at the bottom of the panel.
Remove the rubber cuff of the hatch (for this you need to remove the retaining ring by bending the small spring with a slotted (minus) screwdriver).
Remove the panel.

To get to the pump itself, remove the UBL wires. Remove and disassemble the pump - it may contain foreign objects and debris. The impeller in a serviceable pump turns easily in all directions.

Check the resistance of the pump winding. If it is 200 ohms - order. If the values are different, there is a breakdown, and you need to change the pump.

If water is not collected, you need:

Check if the machine is connected to the water supply (if not, open the valve).
Inspect the drain hose (it may be kinked or kinked).
Check the "AQUA-STOP" filter. If there are problems with it, you need to replace it with a new one.

If the water level sensor breaks down, we change it according to the following scenario:

We find the sensor by removing the top cover of the car - you will see it in the right corner when you look at the car from the front. To remove the cover, twist 2 bolts.
Pressing the latch, remove the sensor. We remove the wires and disconnect the branch pipe by opening the clamp.
We install the new unit in place of the old one, proceeding in the same way, but in the reverse order.

If the heating element has worked out its resource or is overgrown with scale, overheated and burned out, you need to change it. This work can be done on your own. But first you need to check.

If you are not sure whether the heating element is working or broken, you can check it yourself, armed with a tester. The check is carried out as follows:

Without removing the heating element, disconnect the wiring.
Set the tester to measure resistance (in ohms).
Set the adjuster wheel to "200".
Attach the test leads to the electrical heater terminals.
Normal resistance usually ranges from 20 to 40 ohms.
If the tester display is "1", then there was a break, and the heating element needs to be changed.
If the value is about "0", there is a short circuit in the heating element, the heater must be changed.

Finding the heating element is simple: remove the back panel of the CMA and below under the drum you will see the heating element, or rather its shank, with a screw driven in the center. We make a replacement:

Unscrew the bolt.
Remove all wires carefully.
Remove the heater by slowly swinging it from side to side and pulling it towards you.
Take a working heating element and install it.

To carry out this complex operation, an almost complete disassembly of the CM is required. If you decide to do this, do not completely remove all the wires from the electronic module - it is not a fact that you will be able to connect everything in place. After dismantling the module, lay it on the frame or hang it on a special hook.

To make a technological hook with your own hands, take a 30-centimeter piece of non-heated steel wire with a diameter of 3 mm or more. On the wire, you need to string a cambric (heat shrinkage), which should be longer than the wire - at least 1 cm on each side. Make bends, stepping back 6-7 cm from each end of the wire - you will get a kind of hook. Hang the dashboard on this hook.

We remove the tank with the drum by unscrewing the springs.
When disassembling the tank into 2 parts, the specially provided latches must be broken.
Taking a hammer and a wooden backing, carefully knock out the bearing axle shafts with light blows.

When choosing new bearings, pay attention to the fact that the parts correspond to your brand of washing machine. For example, you need bearings for a Bosch Max 5 washing machine - say so in the store so as not to buy the wrong parts.

The video shows how the master disassembles the Bosch machine and changes the bearing. See if this is useful to you:

As you can see, repairing Bosch washing machines with your own hands is a completely doable task.Just remember to periodically clean your washer and maintain it to keep your washer from breaking down.

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:

Close the drum door of the machine.
We put the program selection knob to the "Off" position.
We are waiting for 2-3 seconds.
Now we turn the knob to spin mode.
We are waiting until the "Start" button on the machine's control panel flashes.
Hold down the "Spin speed" button.
We are waiting until the "Start" button flashes again.
We turn the knob to the "Drain" mode.
Important! You need to rotate the handle clockwise.
We release the button "Spin revolutions".
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 provided for diagnostics of hot or cold water inlet valves, in position 8, testing of the water inlet valve will begin 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:

The water does not heat up during washing.
Water does not drain.
The drum does not rotate.
Noise inside the drum.
No water is drawn.
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.
