Details: bosch classixx 4 do-it-yourself repair from a real master for the site my.housecope.com.
We continue the series of articles on the repair of Bosch washing machines.
How to start the service mode, troubleshoot basic faults in Bosch Maxx4.
Here are examples of washing machines of this model range: wfc 2060, wfc 2063, wfc 1663, wfc 2062, wfc 1600, wfc 1662, wfc 2065. Their difference is in the control panels, the filling is about the same, so the repair and operating instructions are similar.
For diagnostics, you can run a service check of the nodes:
1.program control knob to “OFF” (0)
2. simultaneously press two buttons of additional functions
3.The program selector to the position of cotton 30 degrees, the LEDs work and the end of the program light up
4.Select the tested item with the selector clockwise:
- cotton wash 60 degrees (electric motor test) - cotton wash 60 degrees economical (drain pump) - cotton 90 degrees (water intake, maximum heating with a heating element) - rinsing (valve check pre and main wash) - spinning (main wash valve) - drain (preliminary valve)
5. to start, press the "start" button
If a malfunction is detected, an error code is displayed.
Let's look at the combination of indicators:
1.Mistake of the hatch door lock
6.Water heating does not correspond to the program
7.Fault temperature sensor
To eliminate and replace faulty devices, look at the pictures.
Remove the top cover, take out the detergent drawer, and unscrew the fixing screws securing the control panel.
To remove the front panel, dismantle the lower decorative strip and unscrew the screws.
A common complaint from owners of Bosch washing machines is the assertion that the laundry is poorly rinsed out. What can I say here? A feature of many models of this brand is effective washing with low water consumption. Washing, not rinsing. It's just that, unlike other machines, the laundry does not "float" in large amounts of water. Water may not even be visible in the drum during the wash cycle. This is often a psychological factor. If the water in the tap is too soft and the laundry is not rinsed out, there are two ways - to reduce the amount of detergent or to turn on the additional rinse function before starting the washing machine. You can turn on the second spin rinse after the end of the main cycle.

Weak spin. The Bosch brand has a lot of modifications equipped with a system for suppressing imbalances during spinning. Its feature is a decrease in speed or a complete shutdown of the spin when a problem occurs. This is not a breakdown, but protection. You just need to manually distribute the laundry in the drum and the problem disappears.
Malfunctions of Bosch washing machines, which are available for self-repair.
Most modern Bosch machines are capable of eliminating guesswork - what's wrong? On the screen of their display, the type of malfunction is diagnosed using a specific code.
If everything is the same, check the pump. All Bosch machines are equipped with float trays to prevent leaks. Therefore, it will not be possible to get through the bottom to the drain pump. But these washing machines provide for the removal of the front wall. Not the most difficult procedure. Before you start working with the case mountings, it is important to know that at Bosch all screws have a sprocket configuration of a certain size. We'll have to prepare and stock up on the right tool. Now let's get started. What to do?
Remove the powder drawer and fabric softener. Inside it there is a special key for this. Then unscrew 3 screws and remove the control panel.
We do not touch the wires. Next, remove the hatch cuff. Pull back and remove the spring clamp and remove the cuff from the body.We squeeze the latches of the hatch locking device. If there are screws, unscrew them and push the lock inward. We find the rest of the attachment points of the front wall. Depending on the modification, they can be under the lower decorative panel or at the bottom of the case. We unscrew the fastening screws and remove the front wall. Access to the inside of the Bosch washing machine is open.
Now we can remove the drain pump for replacement or repair. It is possible to remove the pump with filter and pipe. The filter is usually secured with an external self-tapping screw, and the branch pipe is held on by clamps. The pump is mounted on three screws, which will need to be unscrewed and disconnected from the wires. We check the entire system for blockages. If the pump has become unusable, we replace it with a new one and install the entire drainage system in its original place. After that, the body of the Bosch washing machine is assembled back. The performance of the machine is checked.
The first thing to do is to check for the presence of water in the water supply. Then the condition of the inlet hose - are there any kinks or kinks. Some Bosch machines (which have the 4th digit in model 4) are equipped with the AquaStop system. If this protection is triggered, a corresponding message will appear on the display screen. We check the condition of the filter mesh at the water inlet. We carry out cleaning if necessary.
If the previous methods did not help, most likely you will need to replace the water level sensor (or another name for the pressure switch).
Replacing the pressure switch on your own will not be difficult. To carry out this operation, you will need to remove the top cover of the machine. Unscrew the two screws and pull back. In the opened space on the right of the case is the same round sensor. It rests on a latch that must be squeezed out. The hose is disconnected from below and the wires are disconnected. You need to remember or write down how they are installed. We take a new one and put it in the reverse order.
To remove the non-working heater, you will need to remove the back cover of your Bosch washing machine. The tank of the car will be visible inside. Below on the tank you can easily find the outer part of the heating element, to which the wires are connected. To remove the heater, you need to unscrew the bolt on which it is attached and disconnect the contacts. The wires are marked accordingly. It is necessary to remember their location on the heater. The heating element is removed, and a new one is installed in its place. Everything returns to its place. The problem has been resolved.
These symptoms can be caused by wear on the drum bearings or a foreign object getting between the tub and the drum of the washing machine. The problem is already much more serious, but not at all insoluble. You will have to practically completely disassemble the washing machine. The laboriousness of the process of replacing the bearings of a Bosch washing machine is more than compensated by the fact that you do not have to pay a lot of money that service specialists will ask for the same process.
You can try to remove a foreign object from the tank with something like a hook, but if it does not work out, all the same actions are used as for changing the bearing.
Before disassembling the machine to the ground, it is worth checking if the noise is caused by a problem with the shock absorbers or a loose balance weight mount. There are actually two cargoes. One under the top cover and easily accessible. The second is under the front panel of the washing machine. You have to take it off. We have already discussed how this is done earlier. If necessary, tighten the fasteners. The condition of the shock absorbers is also easy to check with the body panel removed.
The process for replacing bearings for Bosch washing machines is not very different from the same procedure for machines from other manufacturers. The disassembly process may differ in that the tank is removed using the removed front panel. Dismantling the tank itself compares favorably (in terms of convenience) from Aristons and Indesites in that they are collapsible and do not need to be cut. The re-assembly is about the same though.Original bearings are unlikely to be realistically purchased, but it is quite easy to pick up using old ones as a sample.
Household appliances from Bosch have earned the love of customers for their quality. German-assembled washing machines evoke admiration, ranging from the quality of the materials used for the production of machines and ending with their ergonomics. However, even among this technique, there are copies of machines that fail. That is why, we decided to write an article on how to repair Bosch washing machines on our own, and whether it is possible to do it.
Modern models of machines from Bosch are equipped with a special program that allows you to identify equipment malfunctions without contacting the master. The instruction manual will probably tell you how to make such a diagnosis correctly. If not, then we offer a detailed algorithm for testing machines, in the case when the drum has stopped rotating:
Close the drum door of the machine.
We put the program selection knob on the "Off" position.
We are waiting for 2-3 seconds.
Now turn the knob to spin mode.
We are waiting until the "Start" button on the machine's control panel flashes.
Hold down the "Spin speed" button.
We are waiting until the "Start" button flashes again.
We turn the knob to the "Drain" mode. Important! You need to rotate the handle clockwise.
We release the button "Spin revolutions".
By the error code of the Bosch machine, we determine the last malfunction.
For your information! If the washing machine diagnostics did not start at all, then there is a malfunction in the system board.
In addition, the program provides for deleting the last error from memory and starting diagnostics of faulty elements. To start the engine check, you need to set the mode selector knob to position 3. When the knob is set to position 4, the drain pump will be checked, and in position 5 - by the heating element. Positions 6 and 7 are provided for diagnostics of hot or cold water inlet valves, in position 8, testing of the water inlet valve will begin during the main wash, 9 - preliminary.
The masters of Bosch service centers found that of all possible breakdowns of washing machines, the following malfunctions are most often encountered in Bosch machines:
The water does not heat up during washing.
Water does not drain.
The drum does not rotate.
Noise inside the drum.
No water is drawn.
The engine will not start.
Based on this list, we can conclude that in washing machines of this company, the heating element most often burns out. If Teng burned out, and the electronic system remained intact, then the repair will be carried out quickly and safely. Otherwise, you will have to change expensive electronic modules, giving the technician to the master.
What malfunctions can occur in the washing machine, everything is clear. And what can cause a breakdown, you need to find out. Let's deal with everything in order.
If the machine does not drain the water after the wash cycle, this may be due to:
breakdown of the drain pump (pump);
clogged drain filter or pump;
contacts between the pump and the power supply are faulty;
the water level sensor is out of order.
In the case of stopping the drum, the most important reasons are:
wear of the drive belt;
malfunction of the electronics or control board;
it is very rare that the engine breaks down in such machines.
Drum noise can be caused by:
faulty bearings;
a small object stuck in the drum;
breakage of shock absorbers;
torn off counterweight.
When water is not collected in the washing machine tank, the following reasons are distinguished:
lack of running water;
blockage of the pump or Aqua stop system;
occurred by the kink of the drain hose.
The engine of the Bosch washing machine may not start due to a breakdown in the electronics or an open drum door... Having found out the cause of the breakdown and its severity, you can start repairing yourself.
If the breakdown is still not determined, we turn to the master.
Now we will describe in detail what malfunctions can be eliminated with our own hands, how to repair a car. Let's start with the simplest thing - a clogged drain filter. It is located at the bottom, under a panel or cover. To rinse it from accumulated debris, you need to open the lid by gently turning it counterclockwise. Be sure to use a large rag to prevent any leftover water from spilling onto the floor. Rinse the filter under running water and reinstall.
Cleaning or replacing the drain pump will not be complete without removing the front cover of the machine. This process is simple, but time consuming. This work is described in detail in the article on how to repair a pump in a washing machine.
With your own hands, you can eliminate the malfunction associated with the fact that water is not collected. First, we check if the water supply is turned off and if the water supply valve is open. Then the drain hose is inspected for kinks, and only then can the Aqua stop filter be checked. If it is not working properly, then it is necessary to replace it with a similar one.
If the water level sensor is broken, it must be replaced. The sensor is located under the top cover in the right corner. To remove the cover, it is enough to unscrew the two self-tapping screws from the back. The sensor itself is pulled out by pressing the latch. Then the hose is removed and the contacts are disconnected. A new one is installed in place of the faulty water level sensor.
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.
