Details: washing machine bosch wff 1200 DIY repair from a real master for the site my.housecope.com.

Is it possible to repair a Bosch washing machine with your own hands? Experts answer in the affirmative: in many cases, the owner of the unit himself, without special skills, can restore his working capacity.

An increasing number of users have recently been interested in information on how exactly to do this.

After all, the strategy of reducing the cost of production by transferring production to China and using cheaper materials could not but affect its quality. This article describes how to fix typical breakdowns, as well as measures to prevent their occurrence.

Before proceeding with the repair, you should accurately identify the malfunction. Thanks to the self-diagnosis function, this task is solved today quite simply, because the washing machine itself can tell about the reason for the failure. In order for the unit to "speak", you need to perform a simple magic ritual:

After closing the door to load the laundry, turn the program selector to the “Off” position.
After a pause of 2 - 3 seconds, move the same switch to the "Spin" position.
As soon as the "Start" button LED starts blinking, press and hold the "Spin speed" button. In this case, you need to continue to monitor the LED - it should blink again.
At the signal of the "Start" button LED, the program switch is moved to the "Drain" position (the regulator is turned only clockwise).

We release the button "Spin revolutions" and using the program selector we tell the machine what exactly it should check:

to test the engine, the switch is moved to position "3";
drain pump: position "4";
Heating element: position "5";
hot water filling valve: position "6";
the same for cold water: position "7";
valve check during the main and prewash: positions "8" and "9", respectively.

In some models of Bosch washing machines, the assignment of positions may be different, for example, position "4" is sometimes used to check the engine.

At the end of the test, an alphanumeric code will be displayed on the machine display, which can be used to determine the nature of the malfunction.

In some cases, the owner can guess about a particular malfunction without the self-diagnosis function. Here are the most common symptoms and their causes:

So, let's see what types of repairs are available to the average user.

The most susceptible to clogging is the drain filter. It is located at the bottom, approximately where the drain hose exits from the machine.

In most models, this element is closed with a lid, which must be turned counterclockwise to open.

It is necessary to clean not only the filter itself, but also the place of its installation - a lot of dirt also collects here.

The inlet filter is easy to find where the filling hose is connected.

Before removing the drain filter, you need to spread a few rags on the floor under the filter: usually, during this operation, some water is poured out of the machine.

This unit will become accessible after removing the front panel. Here's what to do:

take out the powder distribution hopper;
unscrew the screw located in the lower right corner;
remove the bottom panel by first unscrewing the screw near the drain filter, and then located at the bottom of it;
remove the hatch seal, after removing the metal ring fixing it (for this, you will need to bend a small spring with a screwdriver);
you can now remove the front panel by pulling on the bottom edge.

To get to the drain pump located at the bottom of the machine, it is necessary to disconnect the wires from the hatch lock. Next, the pump must be removed, disassembled and checked if a foreign object has fallen inside it. The impeller should rotate freely in both directions.

If it was not blocked, you need to check the resistance of the pump winding with a multimeter. It should be 200 ohms. Depending on the breakdown, the pump is repaired or replaced with a new one.

The Italian Candy washing machine has found its fans in our country because of the optimal ratio of price and quality for products. Small breakdowns sometimes occur during operation and it is not always necessary to pay the masters to repair the unit. Washing machine Kandy - DIY repair of basic faults, read on.

What nuances you should know when installing a washing machine in the kitchen, read in this thread: https://my.housecope.com/wp-content/uploads/ext/740/cancliz/mnogokvartirnyie-doma/santehnika/kak-podklyuchit-stiralnuyu -mashinku-na-kuhne.html. Connection from the point of view of a designer and an engineer.

To access the heater in Bosch washing machines, you need to remove the back panel of the cabinet. Below on the tank you can see two contacts with wires connected to them - this is the heating element shank.

First of all, you need to check the performance of this element by measuring its resistance with a multimeter. It should be approximately 30 ohms. If the device shows "infinity", the heating element needs to be changed.

To remove it, it is enough to unscrew the nut between the contacts, having previously disconnected the wires. If the part is stuck, you can gently hit it several times with a rubber hammer. You can soften scale deposits with WD-40 liquid.

After removing the heating element, the edges of the hole inside the tank must be descaled. The next step is to install a new heater.

It is important to install a heating element designed specifically for use in your model. An inappropriate heater can burn out immediately, together with the electronic controller.

The inoperative pressure switch needs to be replaced, but you shouldn't rush into it.

Perhaps the sensor is working properly, just a plug of dirt has formed in the tube attached to it. In this case, it is sufficient to simply unclog the tube.

The level sensor is located in the right corner under the top cover (held by two screws on the back).

Measure the resistance of the sensor at room temperature, and then - in a heated state (you can dip it in hot water for a while). In a working sensor, the resistance should change.

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.

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

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

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

One of the most common causes of engine stalling is drive belt wear. You can replace it yourself with patience and dexterity. This is done as follows:

open the back cover;

we take a photo of the drive belt and its correct attachment to the grooves of the pulley to make it easier to put on a new belt;

we grab the belt with our right hand slightly below the pulley and pull it towards ourselves;

with the left hand, slowly turn the pulley counterclockwise; with this movement, the belt will be easily removed from the pulley;

we get it out of the car body;

now we take a new belt and first put it on the engine;

we pull it with our left hand, and with our right we try to put the belt on the pulley;

while continuing to tighten the belt, turn the pulley counterclockwise, while trying to put on the belt to the end;

close the housing cover.

As we have noted, worn bearings, shock absorbers and a torn counterweight can cause drum noise and hum. We figured out the replacement of bearings, we will consider how to eliminate other malfunctions.

Before changing the shock absorbers, carefully inspect the drum of the machine, shining a flashlight inward, perhaps a foreign object is stuck in it, which can be pulled out without disassembling the body of the machine and the tank. Perhaps this particular object rattles during the rotation of the drum.

As for the shock absorbers, they, like in many other washing machines, change according to the same algorithm. There is a detailed article on this topic on how to change springs, shock absorbers and dampers.
If the noise is caused by a loose counterweight on the mount, then tighten these mounts. The counterweights are located under the upper housing cover and at the bottom.

If you cannot fix the counterweight, then you need to replace it with a similar one. This failure is quite rare.

German electric motors for washing machines are a model of quality that rarely breaks down, nevertheless, it happens.

There are two ways to solve the problem. The first involves dismantling the engine and handing it over to specialists for bulkhead and repair. There is a chance that they will be able to fix this expensive unit. If repair is not possible, then you will have to make a replacement, and in some cases this is almost 1/3 of the cost of a washing machine.

Getting to the engine is easy. You just need to dismantle the back wall of the machine, then look under the tank, there is an engine with a drive mechanism. To remove it, you need to disconnect the supply wires and the sensor from it, and also unscrew the three fasteners that hold the engine. Before removing the engine, experts recommend checking the sensor capacitor for operability. To do this, arm yourself with a multimeter and connect its probes to the contacts. The value on the instrument panel should be from 20 to 50 ohms.

You will also need a multimeter to check the electrics of the washing machine. If you suspect a wiring malfunction, methodically check all contacts, terminals, plugs. With prolonged use of the machine, the wire could, for example, fray and create a problem - check everything, do not be lazy and you will be rewarded.

If you suspect a malfunction of the washing machine control unit, the only thing you can do is either call a specialist who will come and solve the problem, or dismantle the control unit and hand it over to a service center. Experts strongly advise against getting into the electronics of German technology: changing programs, reflashing, connecting to a computer and testing. To do this, you need to know many nuances - entrust this work to professionals.

What happened, why Bosch washing machines that have proven themselves on the market began to break down more often, because this is one of the most reliable companies? And all because some of the enterprises from Germany were transferred to Turkey and Russia, where they began to use cheaper parts.

For example, the metal tank was replaced with a plastic one, and some of the parts were purchased in China. Cheaper products and led to a decrease in quality.

The German quality standard remains only in those washing machines that are assembled in Germany.

Therefore, when purchasing such a machine, you need to pay attention to where it was going. And if a breakdown occurs, then specialists will be able to repair the Bosch machine without any problems. Although partially, it is still Bosch.

So, do-it-yourself repair of a Bosch automatic machine can be overwhelming, in some cases you cannot do without the help of a specialist. However, serious breakdowns in this technique are quite rare; after all, Bosch washing machines are of high quality. And in each individual case of malfunction, you need to approach the repair creatively.

In this article we will tell you how to independently repair Bosch washing machines (Bosch). Find out how to fix light and moderate breakdowns without resorting to the services of a master.Bosch washing machines attract attention and deserve the respect of customers due to their high quality and an abundance of innovative technologies. The German assembly fully justifies the price of such washing machines - high-quality materials are used in the manufacture, and the developers prefer ergonomic forms. But even among the highest quality equipment, breakdowns are not excluded.Bosch washing machine diagnostics is a built-in function in all modern washing machines. Thanks to her, 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 diagnose yourself, we will describe in detail how to do this:

Close the loading door.

Set the program selector dial to OFF.

Wait a couple of seconds.

Set the selector to the "SPIN" mode.

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.
Clogged pump or Aqua-Stop system.
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 causes of 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 the bottom by laying 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.
By 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, we 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 needs to 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 a Bosch machine and changes the bearing. See if this is useful to you:
