Technique always breaks down at the wrong time. If you have a question on how to disassemble a Bosch washing machine in order to check and repair it, use our tips. You will be able to independently inspect all parts and diagnose breakdowns, as well as replace defective elements. In the article you will find step-by-step instructions with photos and videos.
Before disassembling a Bosch washing machine, you need to properly prepare for this. You must present the CM diagram and the elements that will have to be removed.
The disassembly scheme is identical for different models of cars: Bosch Max 4 (Bosch Maxx 4), Bosch Max 5 (Bosch Maxx 5), Bosch Max 6 (Bosch Maxx 6).
What stages of disassembly you have to go through:
Remove covers: top, back and front.
Pull out the detergent drawer.
Remove the control panel.
Dismantle the motor, intake valve, pressure sensor.
Disconnect connectors and wiring.
Disconnect connections and hoses.
Unscrew the weights and supports.
Remove the cuff clamp, take out the UBL.
Take out and disassemble the tank.
What tools do you need:
Screwdrivers: slotted, Phillips, hex.
Hammer, chisel.
Torx keys.
Nippers.
Pliers.
You need enough space to disassemble your Bosch washing machine.
Disconnect the washing machine from the mains, turn off the water supply. Then prepare the container, unscrew the inlet hose from the CMA body and drain the remaining water into it. Go around the car, open the hatch on the bottom of the front panel. Unscrew the filter and drain the water.
The preparatory stage is over, it remains only to move the washing machine so that it is convenient to move around.
So, you have prepared everything you need, get to work.
Take a Phillips or Hex screwdriver and remove the two screws from the back of the machine. Now slide the cover forward and lift it up. Be careful, the edges of the panel may be sharp. Set her aside.
Moving to the front, pull out the powder dispensing tray. Pressing the latch in the center, pull it towards you and remove it from the case.
Next, unscrew the bolts located behind the tray, as well as the bolts on the other side of the panel. Gently release the plastic clips (you can pry it off with a flat screwdriver), detach the panel. To completely remove it, you will need to disconnect the wire connectors - it is better to photograph them in advance. But it's easier to hang the panel from the side, on the service hook.
Remove the bottom cover. It is located at the bottom of the front panel. To do this, it is enough to open the latches. Set it aside.
First of all, open the hatch door. Before disassembling the door of the Bosch washing machine, remove it from its hinges by unscrewing the fastening screws. This must be done so as not to damage the glass of the sunroof.
Bend the hatch cuff and, prying the clamp with a screwdriver, pull it out of place. Insert the sealing rubber into the drum.
Remove the bolts securing the door lock. Place your hand behind the body and take out the UBL. Disconnect all wires from it and set the lock aside.
Having unscrewed the self-tapping screws around the perimeter of the front panel, carefully remove it and set it aside.
Using a screwdriver, unscrew the bolts around the perimeter of the cover, remove it. Behind the panel, you will immediately see the internal components of the Bosch washing machine.
Unscrew the self-tapping screws of the upper bar that connects the two parts of the case. Using a 14mm wrench, unscrew the bolts and remove the upper counterweight. Do the same with the counterweights that are located around the hatch.
How to disassemble a Bosch washing machine further? To get out the tank, you need to free up space as much as possible, and also disconnect all the parts attached to it.
To remove the cuvette of the dispensing tray, disconnect the pipe leading to it. If it has a clamp, use pliers to unclench it. Also remove the inlet valve tube.
Now disconnect the pressure switch and the noise filter. To do this, disconnect the wiring from the parts, unscrew the mounting bolts. Remove the tube from the pressure switch. Pull the parts out of the housing.
From above, the tank no longer holds anything.
Now you need to disconnect all fasteners and elements.
Remove the drive belt by pulling slightly towards you.
Disconnect the wires leading to the motor.
Remove the bolts that hold the motor to the suspensions.
Slightly swinging the motor from side to side, remove it from the case. Caution, the part is heavy!
It is necessary to lay the washing machine on its left side, remove the bottom (if any) by unscrewing the screws.
We disassemble the Bosch washing machine:
Use a pair of pliers to loosen the drain pipe clamp.
Disconnect it. Be careful, there may be water in it.
Unclip the wires leading to the pump.
Unscrew the bolts that secure the drain pump and remove it.
Little is left before dismantling the tank. Disconnect the wires from the heating element. The heating element in Bosch cars is located in the front, under the tank.
You do not need to pull out the heating element, otherwise you will tear the sealing rubber, which cannot be restored.
Sometimes wiring is attached to the walls of the tank, fastened with bundles. Bite the harnesses with wire cutters, move the wires to the side. Now you need to remove the shock absorbers.
Slide a knob over the back of the damper rod to push in the latch.
Pull the stem towards you with pliers and pull it out of the hole.
Do the same with the second shock absorber. It remains to remove the tank from the springs. Lift it up from the edges of the hatch and pull it out through the front compartment.
There is not much. Now we will tell you how to disassemble the drum of a Bosch washing machine with your own hands. Fortunately, the tank in typewriters of this brand is collapsible.
Disconnect the pulley. Install a prop to block the rotation of the pulley. Remove the center bolt. If it doesn't immediately respond, use the WD40 tool.
Remove the bolts around the perimeter of the tank that hold the two parts together.
Remove the top half.
Turn the bottom of the tank over.
Using a hammer on the stem, remove the drum.
The bearings are now accessible. If you need to get them out, remove the oil seal by prying it off with a screwdriver.
Place the chisel on the outer bearing race and hammer out in a circle.
During the disassembly process, you can carefully inspect all the details of the washing machine. In the event of a malfunction, they must be replaced.
Scale often forms on the walls of the tank and on the heater, which is now clearly visible. Before reinstalling, clean all elements well, thereby prolonging the life of your AGR. Otherwise, soon you will have to do disassembly again to replace the faulty element.
As you can see, you can do this kind of repair yourself. Therefore, if you are confident in your abilities, get to work.

Today, washing machines are a common feature in apartments and private houses. Bosch washing machines are very popular, since they are made from high-quality materials using modern technologies. But even such cars can fail over time. This article will show you how to repair your Bosch washing machine with your own hands.
Modern Bosch washing machines contain a special program that allows you to identify faults without asking for help from a master.
The operating instructions for your Bosch washing machine should contain information on how to perform this diagnosis. If the drum has stopped rotating, then you must perform the following sequence of actions:
Close the door;
Set the program selection knob to the "Off" position;
Wait a couple of seconds;
The spin handle should be set to the “Spin” position;
Then wait until the "Start" button starts blinking;
Hold the "Spin RPM" button pressed;
Wait until the "Start" button flashes again;
Set the handle to the "Drain" mode;
Release the button "Spin revolutions";
Determine the last breakdown by the error code for the Bosch washing machine.
The program clears the last error from memory and runs diagnostics. To check the electric motor, set the mode selector knob to position 3.
To check the drain pump, set the knob to position 4. You can check the heating element by setting position 5. Diagnostics of the hot or cold water inlet valves is carried out by selecting positions 6 and 7. When position 8 is selected, the water inlet valve is tested during the main wash, and 9 - preliminary washing.
According to the technicians of Bosch service centers, the following breakdowns are most common:
Water does not heat up during washing;
Water does not drain;
The drum does not rotate;
The drum of the washing machine makes a noise;
Water is not collected;
The electric motor will not start.
When analyzing the malfunctions, one can come to the conclusion that in washing machines Bosch most often comes out of the heating element while standing. If the heating element is broken and the electronic system is working properly, then the repair will not take much time.
However, if the electronic system is also out of order, then the repair will be quite expensive. After all, you will have to replace the electronic modules and call the master.
There are a number of reasons why a Bosch washing machine can fail. Let's consider them in turn.
She may not drain the water at the end of the wash cycle for one of the following reasons:
Clogged pump or drain filter;
Poor contact between power supply and pump;
Drain pump defective;
The water level sensor has broken.
The drum stoppage can occur for the following reasons:
The drive belt is worn out;
Malfunction of the control board or electronics;
Failure of the electric motor (rare case).
The drum may make noise during operation. This may be due to the following reasons:
Bearings came out of standing;
Small items are stuck in the drum;
The shock absorber has broken;
Counterweight problems.
It is possible that no water is drawn into the tank. In this case, the following reasons are distinguished:
Clogged Aquastop system or pump;
Lack of water in the plumbing;
Hall of the drain hose.
If the electric motor does not start, then, most likely, the door of the drum hatch is not closed or the electronics are out of order. After finding the cause of the malfunction, you can proceed with the repair.
The drain filter is located at the bottom of the machine, under a cover or panel. To clean the filter - open the cover. To do this, turn it counterclockwise. Filter - rinse and reinstall.
To clean or replace the drain pump, you must remove the front cover of your Bosch washing machine. This work is laborious, but not difficult.
Quite often, there is a malfunction in which water is not drawn into the Bosch washing machine. In this case, it is necessary to check the water supply and the water supply valve. They can be closed. Next, check if there are any kinks on the drain hose. If everything is in order, check the condition of Aquastop. If this element of the Bosch washing machine is out of order, it should be replaced with a new one.
If the water level sensor breaks down, it must be replaced. To do this, first dismantle the top cover by unscrewing the two self-tapping screws located at the back. This sensor should be located in the right corner under the cover. To pull out the water level sensor, you need to push down on the latch. Next, remove the hose and disconnect the contacts. Instead of the old sensor, a new one is mounted.
You can replace the heating element of your Bosch washing machine yourself. To do this, you need to remove the back cover of the Bosch washing machine. The heating element is located below, under the tank. To replace the heating element, proceed as follows:
Unscrew the bolt that secures the heating element to the tank.
Disconnect the wires;
Dismantle the heating element;
Install a new heating element and carry out all the steps in reverse order.
Replacing bearings on Bosch washing equipment is a rather difficult task, since for this you will need to disassemble almost the entire washing machine. Watch a video on how to replace bearings:
Stopping the motor can cause wear on the drive belt. You can replace this element yourself. To do this, you need to perform the following sequence of actions:
Open the back cover of the Bosch washing machine;
Remember how the belt is attached to the grooves of the pulley. Better to photograph this element.
Take the belt just below the pulley and gently pull it towards you.
With your free hand, turn the pulley counterclockwise.
Pull the old belt out of the washer body.
Put a new belt on the motor of the Bosch washing machine.
Tighten the belt with one hand and try to slide the drive belt onto the pulley with the other.
Turn the pulley counterclockwise without loosening the belt. In this case, you must try to put on the belt completely.
Install the housing cover of the Bosch washing machine.
