A BOSCH washing machine may stop working even without any preliminary “bells”. This can happen to both old and new equipment. In the second case, you can have time to replace it. The situation is more complicated when a long-used machine fails. This is usually preceded by malfunctions, which many users do not pay attention to. But the cause of failure may be natural wear and tear of parts and factors independent of operating conditions.

First of all, you need to make sure that there is light in the house and there are no plugs. It is also checked whether the BOSCH washing machine itself is connected to the power supply. These are basic recommendations familiar to all owners of household appliances. Then you need to inspect the outlet, power cord and plug. If external damage is noticeable or a burning smell is felt, then the cause is probably in the wiring elements. You can connect the machine via an extension cord to another outlet and check if that is the problem.

Why doesn't my Bosch washing machine turn on?

Bosch washing machine won't start ?
Pressing the power button does not start the washing mode, while the indicators are on? The hatch door is probably not closed tightly. Try opening and closing the door and check whether a foreign object has entered the space between the hatch and the door. If the machine has not locked the door, the software module will not signal to start washing.

Also, some models of Bosch washing machines may react to the tank being overloaded; check if you have accidentally loaded a large number of things.

A failure in the software control module may result in the signal to start the washing mode not being sent in time. Unplug the machine, wait a few minutes and turn it on again. The machine may lock the hatch door again and start the wash cycle.

If even after these manipulations the washing machine does not start, then more serious reasons are unlikely to be eliminated on your own; here you need the help of a qualified specialist:

• malfunction of the UBL (hatch locking device);
• “sinking” of the power button on the control panel;
• failure or malfunction of the software control module;
• problem with the internal electrical wiring of the washing machine;
• interference filter malfunctions.

Call a repairman if your Bosch washing machine does not start - he will carry out high-quality diagnostics and eliminate all faults in a timely manner.

Replacing bearings yourself

To carry out this complex operation, almost complete disassembly of the SM 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, place it on the frame or hang it on a special hook.

Making a technological hook

To make a technological hook with your own hands, take a 30-centimeter piece of unheated steel wire with a diameter of 3 mm or more. You need to thread a cambric (heat shrink) onto the wire, 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 something like a hook. Hang the dashboard on this hook.

Our service center services any Bosch washing machines. All spare parts are new and original.

Despite careful operation, someday the washing machine may not turn on, and there can be a variety of reasons for this:

1. The reason is electrical. All Bosch washing machines are equipped with a rather weak surge protector, which should smooth out power surges; on Bosch Max 4 machines, in 25% of repair cases a blown fuse is observed. In the new Bosch Max 5 model, this problem is less common. Whether the mains filter is the reason why the Bosch washing machine does not turn on during repair is checked with a multimeter, which shows the voltage level before and after the filter. If the device shows a difference between the input and output, then the problem is different, but if it’s the other way around, then the machine needs to be repaired. If the machine is many years old, then problems may arise with the plug or power cord; these can also be detected using a multimeter. Failures in the electrical system can also be detected through routine inspection. It may also be that the wires have jumped out of the nodes, and because of this the machine may not turn on. Debugging a wiring system is a painstaking job, often requiring the participation of a professional.
2. The reason is that the door is blocked. Each front-loading washing machine is equipped with a door locking system that ensures the drum is sealed and protects against leaks. In Bosch washing machines it works as follows: the locking device, after locking the door well, sends a signal to the control board, after which it starts the engine and the washing begins. If no signal is received from the blocker, the engine will not start. If there really is a problem with the door lock, then this device can be easily changed at home.
3. The reason is the control board. In Bosch Max 4, the voltage from the start button is transmitted to the control board, and in Bosch Max 5 - to the command device. The “Start” button is checked with a multimeter, and the wires that lead to the power button are inspected. If the problem is in the board, then there is no point in trying to fix it yourself; it is best to contact a specialist, because even if you change this part completely, problems may arise. For example, such boards are often sold unprogrammed, and only a professional can write the necessary commands onto them. In fact, all faults that concern the “brain center” of the machine are best repaired by a repair service.

Why do brushes fail?

The main reasons for part failure are as follows:

• constant operation at high speeds, which has a detrimental effect on the brushes;
• systematic overload of the drum, it is better to wash more often, but with a smaller load;
• wear and tear – banal resource depletion;
• surge or constant surges in voltage.

Here are the main reasons leading to brush failure. There are also software defects and mechanical damage, but they can be immediately identified during the initial diagnosis.

Possible causes of malfunction

Turning on a Bosch washing machine may be accompanied by various symptoms:

1. the washing machine may not respond at all to being plugged in and pressing the on/off button;
2. after turning on the machine, one indicator lights up, and then no mode starts;
3. After pressing the power button, all the indicators begin to flash, the washing machine does not work, and not a single washing mode is turned on.

These symptoms may be caused by the following problems:

• lack of normal voltage in the electrical network or faulty socket;
• one of the electrical wires inside the machine is broken;
• the noise filter is burnt out;
• The door lock does not work;
• The control device or electronic board is damaged.

Important! The Bosch washing machine does not turn on - this may be the result of a power surge, so be sure to unplug the machine after washing.

Getting to grips with electrical issues

First of all, if the washing machine does not turn on, we check whether there is electricity in the apartment, maybe the Energy Network employees cut off the power to the house for a while. Then we check the serviceability of the outlet by plugging in a working device, for example, a table lamp. If there is a malfunction, replace the outlet after turning off the power, or call an electrician.
The “weak point” of any machine, and Bosch is no exception, is the surge protector, which is located at the end of the power cord, inside the machine body. It smooths out voltage noise. Since the voltage parameters in the network are not always respected and can increase sharply, which will inevitably lead to the filter burning out, so the machine does not turn on. This part usually cannot be repaired; it is replaced with a similar one.

Note! The performance of the interference filter is checked using a multimeter; it is first tested for breakdown, and then the voltage at the input and output is measured. If everything matches, then the FPS is working; otherwise, it’s not.

During long-term use of the equipment, the power cord or plug may become damaged, which is why the washing machine does not turn on. This happens extremely rarely. But let's not discount him. They also check the wire with a multimeter. In the event of a malfunction, only replacement is possible.

Article on the topic: How to properly wash white clothes in a washing machine

As for the electrical wiring system inside the washing machine, even a careful inspection, without using a tester, can help identify the problem why the equipment does not turn on. Wires between machine components can simply jump out of the connectors, creating a problem when turned on. If nothing is visually detected, then you will have to call all the wires one by one to rule out the cause; the work is not difficult, but painstaking.

Checking the door locking device

All Bosch front-loading washing machines are designed in such a way that the engine starts only after the door hatch is completely locked.
If the hatch is not closed tightly or the locking device does not send a signal to the control board, then the washing machine will not turn on. Changing the hatch locking device is quite simple; the process is similar on all washing machines and is described in detail in the article How to replace the door lock?

Command device and control board

Depending on the model of the Bosch washing machine, voltage is supplied to the Start button, to the command device or to the electronic board. If there is a button, then by applying the multimeter probes to its contacts, we find out whether it works or not, and be sure to call the wires that go to the button.

Important! The voltage on the button must be checked both on and off, and the washing machine itself must be disconnected from the network at this moment.

As for the command apparatus, it fails extremely rarely, and then only after several years of operation. In Bosch washing machines, to dismantle the control unit, you need to remove the top cover of the case and unscrew the front panel. Repairing the programmer is in most cases impractical. It needs to be changed, and it is best to entrust the work to a master.
You can find out what this device looks like and where it is located by watching the video below. Article on the topic: Which dishwasher is better Bosch or Indesit

Likewise, you shouldn’t take on repairing the control board if you don’t know anything about electronics. Even when replacing this part there are some nuances. Some control boards are sold unprogrammed, so you will have to program them before installation, which can only be done by a professional. Therefore, it is better to entrust everything that concerns the “stuff” of operating the machine to a master. Everything else can be completely resolved on your own. Happy renovation!

The indicator is on, the engine does not start

This problem is possible and manifests itself as follows: - water is not poured into the unit; — washing does not start; — it is impossible to select a program.

How to fix the problem?

1. First of all, pay attention to whether the program is selected in principle.
2. If the problem is not in the program, there may be a problem with the door lock. This problem can also lead to the inability to open and remove laundry. There is only one way out - buy a new lock.
3. The machine may make an unusual noise. Then it’s worth checking the taps, the presence and access of water to the unit.

The Bosch machine stopped during the washing process

This problem is manifested by the water drum stopping, therefore, the running program cannot finish working, and the washing unit does not turn off. The reason is as follows: - the hose or pipes are clogged. Needs cleaning. — breakdown in the drain pump (pump). The pump must be repaired or replaced.

Washing is repeated cyclically

When the washing machine restarts after finishing the selected program, this indicates a breakdown in the control module. The program in the module fails, the machine does not “understand” that the process is finished, and gives the command to restart the mode. Reasons: — the tubular electric heater has failed; — The heating element is working, but will soon fail.

The washing machine is leaking

As soon as water is noticed on the appliance or on the floor, immediately unplug the machine and turn off the water supply to the tap. Next, you need to determine where the water is leaking. Possible locations: — At the connection point of the drain hose. The hose needs to be inspected for damage. The hose may have a bend that has cracked over time. - It's leaking from the machine. Then the side panel is removed, the filter and drainage system are checked, but for this you need a special key.

Can't find the leak? In this case, you need to run testing mode and find the problem. The display will show an error code.

Just yesterday everything was functioning normally, but today the Bosch washing machine is not working. It doesn’t matter whether the device stops starting at all or whether it turns on, but not a single program works. This problem must be resolved as soon as possible, otherwise it will lead to the failure of the most important parts of the Bosch machine. The causes of this problem can be a number of malfunctions, which are best left to the professionals of specialized service centers to fix.

1. Replacing wires.
   Perhaps one of the main wires inside the bosh machine was damaged (broken, oxidized, etc.), which caused the problem that the washing machine cannot work.
2. Replacing the interference filter.
3. Replacement/repair of hatch locking device.
   If the UBL fails, the hatch cover cannot be automatically closed and locked. If the hatch is open, the machine will not work.
4. Repair of the command device/electronic board.
   Failure of the control system of a Bosh machine cannot but affect the operating condition of the device. The electronic device is responsible for the correct operation of the commands. Failures in the system lead to the fact that it is not able to switch programs and start the washing process.
5. Replacement of drain hose and pump.
   In this case, the Bosch machine starts, but the programs work in random order, and the water temperature does not warm up to the required level.
6. Replacing the Start button.
   If the button contacts become oxidized, the Bosch machine also cannot start the washing program. The solution is to clean the contacts.

In some cases, problems with turning on a Bosch washing machine do not depend on the equipment itself. This may be a sharp surge in voltage, as a result of which the network filter burns out. Or, on the contrary, the voltage has dropped so much that it is not possible to start the device. It turns on, the washing program is started, but after working for only a few seconds, the machine stops filled with water and the program freezes.

We do Bosch car repairs ourselves

Below we will look at malfunctions and ways to fix them, paying attention to the most common failures and the best ways to solve them.

We repair the drain pump and filter, pressure switch of a Bosch machine

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

To unclog the filter, we proceed according to the following scheme:

1. Let's find the drain filter: it is located at the bottom of the washer body, under the front panel (you can get to it from below by laying the machine on its side) or behind the door of a small technical hatch.
2. You need to lay a rag or place a container - the remaining waste water will flow out of the hole.
3. Turn the filter cover to the left to remove it.
4. Clean the filter and rinse it under the tap.
5. We install it in place. Remember that you CANNOT run SM without a filter.

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

• Remove the detergent dispenser.
• 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 (to do this, you need to remove the fixing ring by bending the small spring with a slotted (minus) screwdriver).
• Remove the panel.

Article on the topic: Why is the LG washing machine leaking?

To get to the pump itself, remove the UBL wires. Remove and disassemble the pump - there may be foreign objects and debris in it. The impeller in a working pump rotates easily in all directions.

Check the pump winding resistance. If it is 200 Ohms, that’s ok. If the values ​​are different, there is a breakdown and the pump needs to be replaced.

If water does not fill up, you need to:

1. Check whether the machine is connected to the water supply (if not, open the valve).
2. Inspect the drain hose (there may be kinks and kinks on it).
3. 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 replace it according to this scenario:

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

Replacing the heating element with your own hands

If the heating element has exhausted its service life or is overgrown with scale, overheated and burned out, it needs to be replaced. This work can be done independently. But first you need a 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:

1. Without removing the heating element, disconnect the wiring.
2. Set the tester to resistance measurement mode (in Ohms).
3. Set the adjuster wheel to “200”.
4. Attach the probes to the electric heater terminals.
5. Normal resistance usually ranges from 20 to 40 ohms.
6. If the tester display shows “1”, then a break has occurred and the heating element needs to be changed.
7. If the value is about “0”, there is a short circuit in the heating element, the heater needs to be changed.

Finding the heating element is simple: remove the back panel of the SMA and below 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.
• Carefully remove all wires.
• Remove the heater by slowly loosening it from side to side and pulling it towards you.
• Take a working heating element and install it.

Elimination of major machine malfunctions

After a thorough diagnosis, malfunctions of Bosch washing machines are strongly recommended to be eliminated as soon as possible. This will help extend the life of your household appliances.

Let's look at the Bosch Maxx 4 as an example. If the Bosch Maxx washing machine does not turn on, then you should first figure out whether this is due to faults in the wiring and its individual components, or whether the reason is in the device itself. First of all, the voltage in the network is checked. If it is, then the next step will be to check the power cables, sockets and circuit breakers.

The reason may be a faulty power button. If it sinks or does not move, it must be replaced. Less common reasons are failure of the main chip and control module of the equipment, breakdown of the electric motor or drum.

If attempts to troubleshoot a Bosch washing machine do not lead to stabilization of the operating process and startup, you must contact qualified specialists for further diagnostics.

  Bosch Maxx 4 door malfunctions If depressurization occurs or the integrity of the rubber braid is damaged, you should replace it with a new one yourself or in a specialized service. The error code during normal operation may be cleared when the washing machine is restarted.
• Problems with draining or supplying
  Bosch Maxx 4 water to the system. It is necessary to check the position of the supply and drain valves and open them. If the error continues to appear, the filters need to be cleaned and replaced. If the pressure in the system is too low, check and clean the pipes and replace the water level sensor.
• Long-term drainage
  of Bosch Maxx 4 can be solved by replacing the water level sensor and cleaning the main pump.
• Incorrect water heating
  , prolonged heating requires checking the thermostat, replacing the heating element, and temperature sensor.
• Damage to the drum
  can be eliminated by loading the correct amount of laundry - frequent overloading leads to abrasion of the belts and complete failure of the unit.

Errors associated with partial collection of detergents in Bosch Maxx 4 or Bosch Maxx 6 can be eliminated by cleaning the container. To prevent such malfunctions of the Bosch washing machine, do not load too much powder and leave it inside the machine for a long time (especially important if the device is built in a damp room).

Presence of noise

When operating a Bosch Max device, it is necessary to diagnose more carefully. If the noise is periodic and appears at the beginning or end of the operating cycle, then the cause is the presence of foreign objects in the corrugated pipes. It is necessary to remove them as quickly as possible to avoid penetration into the system and the occurrence of short circuits and depressurization of individual elements.

If the noise resembles a metal grinding sound, then this indicates a bearing failure. Quickly replacing them with working ones can prevent complete failure of the electric generator.

Disabling a difavtomat or RCD

at startup, it indicates that there is a leakage current in the system (breakdowns to the housing, etc.). It is necessary to check the integrity of the wiring in the house up to the outlet, inspect the household appliance for the presence of exposed wires and moisture getting inside the housing. Self-repair without proper knowledge of electrical engineering is not recommended, since incorrect repair of this breakdown can lead to dangerous situations.

The examples of simple faults listed above using the Bosch Maxx 4 as an example can be diagnosed and fixed at home. If the faults are more complex, you should immediately seek the help of specialists. In such cases, independent intervention in the repair of household equipment such as Bosch Maxx can lead to irreversible failure of the part or the entire system, thereby the cost of repair work can reach the price of purchasing new equipment.

Causes, methods of checking and elimination

Hatch locking device

The machine can be turned on, but the wash does not start. The problem is checked by trying to open the device's hatch. If it opens freely, the UBL is faulty. On some models, when the washing machine does not turn on, the lock on the display lights up.

Replacing the hatch locking device (UBL). You can do it yourself

No response to switching on, no indicator lights

The power button is broken. The network light is on or flashing.

Any washing machine, no matter how high-quality and modern it is, cannot work forever; any mechanism is subject to wear. If you want to use the machine for many years, then in addition to careful operation, you should always pay attention to problems and fix them in a timely manner, extending the life of the washing machine.

The main thing is that you always have the opportunity to diagnose the machine and correct the problems yourself, or contact a service center, where such Bosch washing machines will always receive high-quality repairs, thanks to the prevalence and popularity of this brand. Some DIY repairs are a completely solvable task for every person.

Simply, it is necessary to clean the filters and maintain the washing machine on time. In this case, situations where the machine will not turn on will be minimized.

Independent actions and minimal repairs of a non-working Bosch washing machine

It’s one thing when a Bosch washing machine does not perform one mode or program, and quite another when it doesn’t work at all:

1. No programs are activated and the indicators are lit and/or flashing.
2. Programs do not start and only one LED is on.
3. The “Power on” button is not active.
4. There is no response from the equipment when connected to an electrical outlet.

Article on the topic: Can a men's suit be washed in a washing machine?

What should the owner of a washing unit do,
is not familiar with its structure and, in principle, has no technical knowledge? Try to eliminate the simplest and most easily removable causes of trouble - check:

1. Is there electricity in the house?
2. Is the outlet to which the machine is connected working? If visually everything is in order with the outlet, you should connect another device, known to be working, to it to check whether it turns on.
3. Is the loading door of the washing machine closed properly?

In the first case, all you have to do is wait until the light comes on. In the second , invite an electrician to your home to replace the socket, temporarily connecting the Bosch machine to another, suitable socket.

In the third , open and close the hatch door tightly again, since not a single “smart” Bosch washing machine works if the door is open or not closed tightly.

Note! The door does not fit tightly even if its rubber seal (cuff) is worn out, as well as if the hatch locking device (UBL) fails.

Typical breakdowns of Bosch machines

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

Based on this list, we come to the conclusion that the most vulnerable point of washing machines of this brand 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 this work is best left to a specialist.

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

Drive belt failure

The belt that transmits rotation from the motor to the drum stretches, breaks or falls off. If the belt comes off or breaks, the Bosch washing machine works as usual (drains, fills, heats water), but the drum does not rotate. If the belt slips, then the machine goes through the washing and rinsing cycles normally, but during the spin cycle it does not gain speed.

Article on the topic: How to clean the mesh filter in a washing machine

Note! If the new belt also flies off the pulley, this is a signal that the bearing is faulty.

*The price is only for the work of the master, the cost of a new belt is not included in the price.

Diagnostics of Bosch breakdowns

Diagnostics of a Bosch washing machine is a built-in function in all modern machines. Thanks to it, you can determine the essence of the breakdown without calling the workshop. If you did not find in the instructions a step-by-step description of how to carry out the diagnosis yourself, we will describe in detail how to do this:

Attention! Rotate the selector only to the right.

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 a technician.

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

Next, press “START” again (in addition to this indicator, “DRAIN” and “SPIN” are also lit) to start the program test.

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

To exit the diagnostic mode, turn the wheel to o or “OFF”.

Failures that cause the washing machine to click

Sometimes the machine still starts the wash, but sharp clicks are clearly audible during operation. Let's consider what malfunctions can cause them.

Foreign objects in the housing

Foreign small objects often get caught between the tank and the drum, causing loud knocks and clicks. Usually they first get into the drum along with the clothes, and then penetrate through the holes into the body of the washer. Before washing, be sure to check your clothes for the presence of small foreign objects in your pockets.

Shock absorbers

Shock absorbers dampen possible vibrations that occur during operation of the washing machine and ensure silent operation. Over time, they fail and begin to knock or make clicking noises. If only one shock absorber is worn out, the machine knocks more only on one side. This is a common malfunction that happens with automatic machines.

Network filter

It is needed to smooth out the voltage in the network during surges. The surge protector is most often attached to the rear wall of the machine at the top of the case. If it is loose or loose, it will start hitting the body and tank, making loud knocking noises. To correct the problem, the surge protector must be securely fastened in place.

The same problem can happen with a pulley. This is a system of two rings with a rim, mounted on the back wall of the drum. Thanks to the pulley, torque is transmitted from the electric motor to the drum. If the fastenings are loosened, clicks begin to be heard during the washing process or the machine may not start at all. This is a rare problem, but it does happen sometimes with older models.

Bearings

When the bearings wear out, the drum most often knocks and clicks during spin cycles or when the engine picks up speed. This unit is responsible for the smooth rotation of the drum. If worn-out bearings are not replaced in time, they can eventually puncture the tank or grind off the crosspiece, which will make the repair more serious.

Counterweight

This is a balancing heavy block attached to balance the drum and dampen vibrations. If its fastenings become loose or it begins to fall apart, the counterweight begins to strongly rock the machine, causing it to bounce, knock and click. The mounting bolts need to be adjusted or the counterweight needs to be replaced.

Tank suspension springs

The tank is held in the correct position thanks to springs. There may be a different number of them, two or four, depending on the model. Sometimes one or more springs fly off the fasteners, so the tank hits the body during washing. It is easy to determine the malfunction yourself. You need to press the drum with your hand. If it moves down easily, the reason is a weakened or broken spring.

Checking for damage

First you need to find out whether there is electricity in the house. After all, sometimes there is an unplanned power outage, power surges and short circuits appear, as a result of which traffic jams are knocked out. If after checking the safety circuit breaker the situation has not changed, then it is worth looking for other reasons for the breakdown.

Power failures during the operation of the machine can be characterized by a protective shutdown device, which is triggered if the housing is energized, as well as if you are shocked by an electric shock when touching the surface.

A thorough inspection of the power cord of a Bosch washing unit will allow you to determine whether there are various breaks or abrasions on it, which are formed due to numerous bends or mechanical loads. To check the integrity of the cable, you can use an electrical tester. If such defects are found on the cord, it will require further replacement.

The cause may also be a faulty socket, the suitability of which can be easily checked by simply connecting any other device.

A large number of Bosch washing machines have a power button located on the front panel. Its condition is tested using a multimeter that works as a sound emitter. After disconnecting the machine from the electrical network, select the “on” position. If the device makes a sound, it means that the current flows without interference; if the key is faulty, the tester will not emit a sound signal.

Bosch brand devices have a special network interference filter (IPF), the task of which is to neutralize electromagnetic radiation emanating from the washing machine and which can affect the correct operation of other household appliances. Often, the FPS breaks due to a long service life or a short circuit. In this case, the electrical circuit is interrupted and the flow of current practically stops, which completely destroys the entire device. To analyze the operation of this equipment in practice, a tester is used. First you should ring the entrance, and then the exit. When voltage is present at the input but not at the output, the filter must be replaced.

The washing machine turned on, but the wash does not start

The washing program does not start, although the indicator lights work as normal

Make sure the hatch is tightly closed after loading laundry. Otherwise, a special protective mechanism will not allow the drum to be filled with water. Then make sure that the hatch is blocked after the program starts. If the door just latches, check to see if it has power. The current is supplied, but the hatch is not blocked? Then the locking device will have to be replaced.

Watch the drum fill with water. The presence of unusual sounds or complete silence indicate that water is difficult to get inside, and the machine simply has nothing to wash with.

Did not help? Make sure that you have selected the correct washing program (you have not pressed several buttons at the same time or accidentally poked it past). If in doubt, turn off the machine for 30-40 seconds and then turn it on again. The failure that occurred will be corrected.

The lights flash randomly or light up at the same time

In this case, look for the cause of the failure in faulty wiring. In most models LG, Indesit, Samsung, Hotpoint Ariston, Bosch. Ardo, Electrolux wires often come into contact with internal parts, which causes damage over time. Check the condition of the cables with a tester and replace the problem area.

The problem may also lie in burnt-out capacitors that should be replaced.

These simple tips will allow you to quickly and competently resolve common problems that arise in the operation of your washing machine.

Service test Bosch Maxx 4

During the operation of German Bosch machines, malfunctions occur less frequently than with competitors; however, the manufacturer has equipped each Bosch Maxx model with a special service test, the so-called self-diagnosis mode, which can determine the performance of all system functions. This function is very useful if several system components are broken.

Launching the diagnostic mode is performed differently depending on the line: Bosch Maxx 4, Bosch Maxx 5, Bosch classixx 5, etc.

Let's look at the test using the Bosch Maxx 4 series as an example.

To start self-diagnosis of Bosch Maxx 4, turn off the machine. Simultaneously press the additional function buttons and turn the mode knob 30° clap. After a successful launch, you can begin selecting a test.

Bosch Maxx 4 programs comply with the following tests:

1. cotton 60° - check the electric motor;
2. cotton 60° economy - drain pump;
3. cotton 90° - heater;
4. spin - main valve;
5. drain - pre-valve.

To start the program on Bosch Maxx 4, press the “start” button. Faults are indicated by combinations of LEDs. In older Bosch Max models, error codes are displayed.

Error codes usually appear when one of the system elements fails. A DIYer can save time and money by quickly identifying the error using these codes.

Machines of the Bosch Maxx 4, Bosch Classixx 5, Bosch Maxx 6 series or the Bosch Classixx washing machine indicate incorrect operation with the following symbols:

• F16 - when starting programs, the laundry loading hole is open.
• F17 - exceeding the specified time for water entering the system. The reasons are clogged valves and filters, a closed water supply valve to the system.
• F18 - water drain time has expired. The drain valve may be clogged or the water level sensor may be faulty.
• F19 - the standard water heating time for the washing machine has expired. Typical reasons are low voltage in the network, failure of the heating element or thermostat.
• F20 - no water heating. The thermostat or heating element may fail.
• F21 - drum failure. The breakdown occurs due to a broken relay or tachogenerator reverse.
• F22 - malfunction of the NTC sensor. Associated with a short circuit and breaks in the electrical wiring circuit.
• F23 - activation of the Aquastop system. There is liquid in the pan and there is a break in the electrical circuit.
• F25 - turbidity sensor error.
• F26 - malfunction of the analog sensor.
• F27 - flow switch malfunction.
• F28 - failure of the fluid pressure sensor.
• F29 - incorrect operation of the motor.
• F30 - no engine rotation.
• F40 - violation of synchronization of electrical equipment. The reason is the discrepancy between the local electrical network and the required technical characteristics of the machines.
• F50 - low or high flow rate.
• F51 - door error.
• F53 - functional protection failure.
• F54 - malfunction of the control module.
• F63 - control module error.

Extraneous knocking noises are heard during operation

As a rule, extraneous noise appears during spinning, when the engine is running at maximum speed. There are two main reasons for the appearance of strong vibration and extraneous noise:

1. Bearing wear;
2. Wear of shock absorbers.

On average, bearing operation is designed for 7-10 years. In order to determine problems in the bearings, you need to take the drum with your hand and slightly rotate it back and forth and from side to side. In this case, no extraneous sounds should be heard, and the play between the edge of the drum and the cuff should be minimal. If at least one of the signs is present, the bearings must be replaced. This is a rather labor-intensive and complex repair of a washing machine malfunction, and not everyone is able to do it with their own hands.

The process includes complete disassembly and removal of the tank and drum, pressing out the bearings and seal, installing new bearings, and then reassembling them.

Spinning up the tank

We remove the drum enclosed in a sealed tank from the machine. Unscrew the tank, then remove the drum

We take out the drum

As a rule, there is a significant limescale deposit on the drum. Clean it with WD-40 rust remover.

Pressing out the bearings

Carefully remove the old bearings. This process is called pressing out. This must be done extremely carefully so as not to damage the shaft tip. It is better to use a rubber hammer.

Installing new bearings

We install new bearings on the seat, having previously lubricated the niche with lithol. Be sure to install a retaining ring on top. When reassembling the tank, be sure to use silicone sealant.

The second common cause of knocking and severe vibration is wear of the shock absorbers. Shock absorbers cannot be restored or repaired, and if they break, only replacement will be required.

Replacing shock absorbers

Required tools and spare parts

Experienced craftsmen have long had a certain set of tools. This composition includes not only officially sold tools, but also independently made devices. For home work with Bosch washing machines, you must have a couple of screwdrivers, pliers and wrenches of various sections. It is also worth preparing tweezers-nippers, pliers, a medium-sized hammer, and a metal service hook. It is not advisable to buy expensive branded sets; it is much better to choose equipment for yourself personally. It is also advisable to stock up on a drill, a drift and a metal saw.

If you already have experience in handling electronics, you can also change more serious components - main boards and control units. But it’s better to entrust the work with them to professionals.

In some cases, a tank cross is used. This part is responsible for maintaining the stability of the device. If the crosspiece is broken, a lot of noise and grinding will inevitably occur. Ignoring the defect is dangerous, since the heating element, the drum, and even the tank body may be damaged. In any case, the replacement part must meet strict Bosch requirements. Like other components, it is better to purchase it in the company’s company store.

But special attention should be paid to the motor of the washing machine. The German manufacturer always tries to place it at the bottom

This significantly reduces the risk of moisture damage. But it cannot be completely excluded. The most likely defects are the following:

• mechanical wear of bearings, rotor, stator, coils, windings;
• ingress of liquid, including condensation;
• interruption of power supply circuits.

In some cases, the drive belt slips off the electric motor. It can also become severely worn or weakened by long-term use. They usually try to replace the belts, unless it is possible to simply return them to their place.

The door lock on Bosch washing machines is, of course, very reliable. But this device can also break. The following elements are used to repair it:

• plates;
• pins;
• contacts responsible for transmitting the signal to the control board;
• bimetallic plate.

Sometimes, however, the hatch cover or the glass that is inserted into it is damaged. These parts can also be replaced with skillful approach. But from time to time you also have to service the washing machine pipe. The normal circulation of water inside the housing depends on the three main pipes. And which of these blocks will fail cannot be predicted in advance. We only know that the drain pipe most often breaks. It is he who encounters all kinds of blockages and foreign objects.

Another unit in which problems often occur is the pressure switch of the washing machine. If it fails, the automation cannot determine exactly how much water to pour into the tank, or whether it is necessary at all. In less complex cases, water is still poured or drained, but less than necessary.

Help from specialists

These are the main causes of malfunctions that will help you prepare for the arrival of a service representative. In any case, only a master can tell why the TV turns itself off and on. Do-it-yourself repairs may make the problem worse. offers high-quality home repairs, we work in 80 cities of Russia.
