Do-it-yourself Bosch washing machine repair fuse replacement

In detail: do-it-yourself Bosch washing machine repair replacing the fuse from a real master for the site my.housecope.com.

Few people think that a washing machine, like other serious electrical appliances, may also have a fuse. If a malfunction occurs with an electrician, some masters, having checked the network wire, immediately begin to dig into the control module. This is wrong, you must first find out if the washing machine has such a part as a fuse, if so, then you need to check it and make sure it works, and we will discuss how to do this within the framework of this article.

Before proceeding with the repair, you need to ask yourself whether the washing machine has a fuse at all, since it is quite possible that your model of the machine does not have one. In this case, it is not even the model of the car that matters, but the place where it was made, but first things first. The fact is that all washing machines manufactured in Europe for the EU market have fuses. Electrical appliances without fuses cannot be sold there.

On the contrary, in the CIS countries, and of course in Russia, there are no such requirements, which means that we can sell cars without a fuse. According to our masters, only some models of Indesit and Samsung automatic washing machines of Chinese and Russian production can be found with fuses, but this is rather an exception to the rule.

In the overwhelming majority of cases, if your car is made in China, there are no fuses in Russia or Ukraine. It's another matter if you own a semi-automatic washing machine manufactured before the 2000s or at the very beginning of the 2000s. It most likely has a fuse on it. And it will not be difficult to find it.

For your information! Some novice masters confuse the mains filter of the washing machine with a fuse. In no case should this be done.

Let's start with the fact that there are a great variety of washing machine models. One and the same manufacturer in different models of washing machines can "cram" the fuse in different places, therefore, in order not to guess, look at the electrical diagram of your unit. If problems arise with the search for the electrical circuit from your washing machine, it does not matter, we will try to act "by the scientific poke method."

The washing machine fuse should look similar to the picture above. You can remove the top cover of the machine and visually inspect the insides to look for something similar.

Pay attention to the places where such a fuse is most likely to be installed:

at the base of the power cord inside the body of the washing machine;
directly next to the control board;
inside the power supply;
at the end of the power cord inside the plug.

If you carefully examined the "bowels" of the washing machine, and did not find the cherished fuse, it may not be there. But just in case, it is better to activate and find the electrical circuit of your car, then everything will surely fall into place. It is very possible that the malfunction of the washing machine is caused by a breakdown of the control module. In this case, a publication called Should you repair electronic modules is useful to you?

If you can find a fuse, carefully remove it from the protective cover or special groove on the control board. Next, take a multimeter and check the resistance of the fuse. The defective part must be replaced as everyone knows that fuses cannot be repaired. Purchase a similar fuse at a retail outlet in your locality or order from an online store, put it in the place of the burned-out part and the machine will start working again.

Important! If you don't have a multimeter at hand, you can test the fuse in the old fashioned way (if it's not flat). Bring the part to a light source and examine it under a magnifying glass. There is a thin wire inside the cone; if it is torn, the fuse end.

To summarize, we note if your washing machine has problems with the electrics, then the fuse may have broken. It is necessary to find out whether she has a fuse at all, and at the same time check all possible causes of a malfunction of the corresponding symptomatology. To get a guaranteed result, it is better to contact a specialist, good luck!

Think your washing machine is not working due to a fuse problem? You don't need to take drastic steps until everyone has figured it out.

The fact is that many users confuse this part with a surge protector. Indeed, the noise suppression filter acts as a kind of protective element that eliminates interference that can destabilize the operation of other devices and equipment.

In this article, we'll show you where the fuse is located in your washing machine.

The fuse is located on the control board.

Many foreign AGRs, assembled in Europe, are necessarily equipped with fuses; without them, washing machines cannot be sold. But in models of Russian and Chinese production, the installation of such parts is calculated in isolated cases.

Therefore, your washing machine model may not have this part. We will tell you about where to find the fuse below.

In different models of washing machines, it can not only look different, but also be located in different places. If you do not want to dig into the washing machine for a long time, find an electrical diagram that matches this brand. The location of the item will be clearly indicated there. If you cannot find the circuit, you will have to inspect the places where the fuse can presumably be located. Check:

Inside the plug from the mains wire.
At the end of the mains connection wire, which is located inside the housing.
On or near the electronic board.

Remove the top cover of the CM for a thorough inspection. Unscrew the two self-tapping screws located at the back, push the cover in the opposite direction and remove. What the fuse looks like is shown in the photo below.

If you can't find a part, it might not be in your model.

If the washing machine stops working or is completely turned off, while the power is not supplied, the reason may be a faulty fuse. It could burn out as a result of a sudden power surge. Its principle of operation is to protect the control board during network outages. And since this is not uncommon in our electrical networks, equipment suffers first of all.

Before making repairs, you need to think about how to check the fuse. You can check with a tester with a multimeter. These parts may be different in appearance, but they are checked in the same way.

Do the work in the following sequence:

Set your tester to resistance measurement mode.
Disconnect the fuse from the element on which it is located.
Press the tester probes against the cell pins.
Look at the reading on the screen.
A healthy item will show 0 PS. If the tester did not show anything, then there was a malfunction.

A malfunction may indicate a short circuit in the electronic circuit of the washing machine: for example, a heating element has shorted. You need to check everything properly. Should you replace the fuse yourself? It cannot be repaired, and manipulations with the electronic board can lead to an undesirable effect.Therefore, in this case, it is better to contact the master. A related video will help you self-check:

Needless to say, a washing machine is a hazardous electrical appliance.

She also needs additional security measures.

Therefore, in order to protect the internal electronics from voltage drops in the mains, a fuse is installed in the washing machine.

This part protects not only the control unit, but also the washing machine motor.

When contacting specialists for help in repairing a washing machine, the fuse is not taken into account. He is usually forgotten. This is the wrong approach.

The network cable should not be confused with this part, as is often the case.

There are situations when electricity is often turned off or is supplied with fluctuations, and at this time a washing machine is running, for example.

The presence of a fuse prevents a short circuit in the network, which can burn equipment. If the current increases, it opens the electrical circuit, while its conductive core melts.

Most often, a washing machine's fuse looks like a tube with a glass bulb.

The reasons can be different:

crash of the program;
voltage surge;
failure of machine parts;
mechanical loads;
end of life of the part.

The first step is to find out where the washing machine was made.

If she was born in a European country, then with almost a hundred percent guarantee, you can be sure that there is a fuse in the equipment.
Because in these countries, the sale of such devices without this part is prohibited.
In the countries of the former union, the rules are not so strict, so there is no certainty about the presence of such a component, unless, of course, it is equipment manufactured before the 2000s.

To find the fuse, you need:

Find instructions and study the electrical circuit of the machine.
If there is no diagram, you will have to look into the base of the power cable from the inside of the unit body.
Get out the control board. For example, a fuse in an Indesit washing machine is usually placed at its inlet.
The power supply can also hide this part in itself.
The last place is the inside of the fork.

After the fuse has been found and removed from the car, you will need a multimeter.

This device will show you exactly if the part is broken. If so, you will need a new one. How much it costs depends on the model. But usually the price is not high.

If there is a new component, it is installed in place of the old fuse and brings the machine into working condition.

A fuse is an element designed for a certain current strength, if exceeded, it opens an electrical circuit. In washing machines, as in any other electrical appliance, a fuse serves to protect the internal electronics of the device from power surges in the mains. The electronic control unit and the windings of the electric motor are protected by this device.

If the maximum permissible current in the network is exceeded, the conductive core of the fuse melts, thereby “cutting off” the device from the power source and preventing the electronics inside from burning out. There are automatic fuses, but washing machines are installed, as a rule, fusible. The fuse is a plastic tube up to 10 cm in size, inside which there is a glass bulb with a soft metal conductor, designed for a certain load. From both ends of the element there are outputs that are connected to the phase conductor of the network.

The location of the fuse depends on the specific model, in some cases it may simply be missing. Devices made in Europe, as a rule, are all equipped with this element. In various versions, the fuse can be located inside the power supply unit or at the electronic control module board, also at the end of the power cable or at the beginning of the power plug.

The reason may be a voltage surge in the general network in a room not equipped with a stabilizer, in addition, there may be an internal short circuit in the electronics of the device, work under heavy load, burning of the motor windings. When the fuse blows out, the washing machine immediately stops working; when it is plugged into the network, it does not react in any way - and this is the only indicator of failure.

Experts do not advise doing repairs with their own hands; if you do not know the electronics and the internal device, you can disrupt the operation or disable the control unit. In such cases, it is necessary to contact professionals. The repair is as follows: the master opens the back panel or front console to get to the control module or power supply. If the element is located on the mains wire, then replacement is carried out at the location of the fuse. The specialist has a special device with which he will quickly detect an open circuit and, accordingly, the location of the fuse. How much a replacement costs depends on the model, but mostly inexpensive, since for a specialist it is a simple operation. You need to contact the service center, name the model of the car and find out the exact cost.

In the production of washing machines, as well as other technical devices, a fuse is provided. This is a necessary component of the technology that protects the electrical part of the machine from a voltage failure in the mains.

The fuse in the washing machine is installed if the equipment is manufactured in foreign countries. In the states of the former USSR, this device was not always installed, since there are no clear regulations for the performance of this work. If the production of washing equipment was carried out before the beginning of this century, then it was not equipped with this safety device.

When troubleshooting a machine, you can confuse a surge protector and a fuse, so it is important to know what it looks like.

Manufacturers in the design of the machine can provide for the presence of fuses of different models and install them in any place. It is possible that such a search will take a lot of time, so the best option would be to find an electrical diagram of a technical device. The drawing will indicate the installation location. If this circuit is absent, then it is necessary, based on logical thinking, to determine where the fuse is located.

List of tips on where the part is located:

The part is located in the plug from the main wire required to connect to the power supply.
In the wire located in the equipment case, you should pay special attention to the base of this branch, in most cases they are installed there.
Installation is carried out in the power supply unit of the technical device.
Locations on or near the board.
Study the electrical circuit of the washing machine. So in the production of washing units, the manufacturer ensures the safety of this expensive element.

Still, you should initially look for the element inside the outlet or in the wire.

To make a careful inspection, it is necessary to remove the top cover, that is, using a screwdriver, unscrew a pair of self-tapping screws and push out the cover structure. Further, it is only worth considering whether there is a fuse in technology. In practice, there are cases when the fuses are simply not located, then they are most likely not in the technical device.

In practice, it often happens that during the operation of the washing machine, there was a voltage drop or the electricity supply was stopped. In the absence of a fuse, the electrical part of the device may burn out completely.

In the presence of this element, the short circuit created in the circuit does not affect the equipment, that is, if the indicator of the current strength rises, then this ensures the opening of the electrical circuit and the conductive vein of the wire melts.

Externally, the fuse in the washing machine is identical to a glass tube with a bulb placed inside.

The reasons for the burnout of this element can be different.

Resetting the program while the washing machine is running.
An increase in the voltage indicator.
Additional mechanical overloads.
The fuse has reached the end of its life.
The part is out of order.
Malfunction of one of the parts.

The process for determining the further suitability of a part is as follows:

You need to take a multimeter and set up the device to measure current and voltage.
If the part is damaged, then another one is needed for replacement. According to their price characteristics, these things are usually inexpensive. Currently, it is not difficult to purchase this item, both in the store and order it online. The only caveat is that it is necessary to clarify the name of the model.
Replacement is carried out in the reverse order to removal.

In most cases, when the washing unit stops working, the greatest probability is given to a fuse breakage.

Business advice: in the absence of a multimeter in everyday life, you can use another method, namely, to present a transparent cone to the light and consider the presence of a thin wire in it, if it is intact, then the fuse is operational, and if it is torn, it means that the element has become unusable ...

If the washing machine was recently purchased from technical equipment, the warranty period has not expired, then you do not need to perform independent repair actions, the best solution would be to contact the outlet where the machine was sold from.
In the absence of the skills to repair the electrical part, it is not worth experimenting, let the masters take care of this issue.
When deciding to independently carry out repair work, it is worth carefully studying the manufacturer's instructions.
Children should not be allowed to repair, they do not have knowledge of elementary electrical engineering.

If in any doubt, you should contact a repair shop or call a specialist at home. In service shops, all spare parts are usually available, including the fuses in the range. A guarantee is provided for the work performed.

Before replacing or disassembling the electrical part of the washing machine, do not forget about your own safety. An indicator of current strength of 0.1 amperes or more is fatal to humans.

Therefore, the following measures should be taken:

De-energize the technical device.
Work in rubber gloves and preferably on a dielectric mat. This is necessary if residual voltage remains in the electrical circuit.
Do not come into contact with water during operation. Everyone knows that water is an excellent conductor.
Check all tools for cracks, chips and metal rivets so as not to get injured.

As with any other work, the disassembly of the electrical circuit and the replacement of the fuse should be carried out together.

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).

Rice. one Control panel of the Bosch WFC 2060 washing machine

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.

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 “Spinning 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 begin 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.

The breakage of the buttons leads to the impossibility of setting the desired mode, thus the wash becomes defective. If the on / off buttons or "start" buttons of the machine are broken, it becomes impossible to start the wash. To eliminate a malfunction, it is often necessary to disassemble the control panel of the washing machine, which requires certain skills and abilities. It is advisable to ask for help from professionals in their field - to our service center "RemonTechnik".

During long-term operation with the buttons, the following may happen:

Sticking - the button is constantly pressed and what the luminous indicator light may indicate;
The button may fall out of the socket;
Doesn't execute the command when pressed;
Falls into the nest.

Broken buttons are rare and rare.

If in the first days of operation one of the listed breakdowns occurred, you should contact the service center of the manufacturer, since there is a production defect.

Among the possible causes of breakdowns, the following should be noted:

Mechanical impact. Do not hit or press hard on the buttons;
Contamination. Over time, dust and dirt accumulates under the rim of the button, which prevent contact with the control board, as a result of which the machine may not respond to pressing;
Worn control levers. Such damage occurs only on typewriters whose service life reaches 5 years or more;
Damage to the system board.

You can prolong the service of the buttons with careful treatment and constant cleaning. It should be noted that the most frequently broken buttons are those that are pressed most often, and these are the start, pause and program selection buttons. Other levers rarely break.

If the buttons of the washing machine break down, its further use becomes problematic. If the "start" button breaks down, the machine will not turn on at all, and if the washing mode selection buttons are faulty, the washing quality may deteriorate. You can use the washing machine if an insignificant button breaks. But still, it is worth establishing the cause of the breakdown, so that it does not spread to other elements of the washing machine. Since the cause of the breakdown may lie not in the button itself, but in the control module. If the control unit fails, then the cost of repairs increases significantly.

In modern washing machines, touch control panels are replacing mechanical buttons, the breakdown of which is not associated with the above reasons.

Do not repair your washing machine yourself if you are not sure that you will do everything right. The process of cleaning and replacing buttons includes the following steps:

Remove the top cover, which is held by two self-tapping screws located on the back wall. Make sure. That the machine is disconnected from the network and the water supply tap is turned off;
Disconnect terminals and supply wires. Usually all terminals are foolproof - all of different sizes. But in any case, we recommend capturing all the steps taken in the photo.

Unscrew the control unit and gently pull it towards the rear wall of the machine, thus opening up free access to the buttons;
At the final stage, the keys are cleaned or replaced.

We also recommend paying attention to the state of the motherboard. Are there any darkening, blown fuses, swollen capacitor heads. The assembly process of the washing machine is carried out in the reverse order.
