Tips and tricks for repairing and replacing the board of a Bosch washing machine

Bosch washing machines are appliances with a “German” character. They are distinguished by impeccable operation and rare breakdowns. However, over time, even the best household appliances break down.

A malfunction of the electronic module can be a real headache, since it is the one responsible for executing all programs.

Read the article about what to do if you need to repair the control board of your Bosch washing machine.

Signs of a control module failure

It is not difficult to guess that the electronic module in a Bosch washing machine has broken down. Signs of malfunction:

1. The machine doesn't work. It does not turn on at all, or does not respond to commands. This is the most dangerous sign, as it indicates 100% failure of the part.
2. The device turns on, one of the following codes appears on the screen: F00, E00 - firmware failure, F67 - control board failure.

   If individual tracks on the module burn out, any other code may appear. It will correspond to the element whose operation is controlled by the faulty part of the board.

3. The program starts, but it crashes, after which the cycle starts over. This can happen an infinite number of times.
4. The water does not heat up or gains temperature very quickly.
5. The water is drained and collected in the drum, but the wash does not start.
6. The drum rotates quickly or slowly.

These are the most common signs of a board malfunction, indicating its failure. However, you should not panic; first you need to eliminate the possibility of its one-time failure. The machine is restarted by holding down the “Start” button for 5 seconds.

After turning off the device, leave it alone for 15 minutes and then turn it on. If the error code appears again or the machine continues to operate abnormally, repair is required.

Bosch washing machine under warranty: what to do?

If a machine whose control board has broken is under warranty, then with a high degree of probability the cause of the malfunction is a manufacturing defect. The manufacturer Bosch provides a 1-year warranty on its household appliances.

If a breakdown is detected, you must contact a retail outlet or a Bosch service center. You must have proof of purchase with you in the form of a check or receipt. They are needed to confirm the date of purchase of household appliances.

The service center is required to repair or replace the faulty control board free of charge during the entire warranty period. In this case, the consumer must be provided with a certificate stating that the machine was sent for diagnostics and repair. It states the date and time of the request, and also indicates the client’s complaints.

The manufacturer may refuse service in the following cases:

• the machine was opened and an attempt was made to repair it outside the service center;
• it will be proven that the cause of the breakdown is a violation of the rules for transporting equipment;
• the manufacturer finds out that the malfunction occurred due to the user’s fault, due to improper handling of the device or for some other reason;
• the board has burned out or been damaged by rodents and insects;
• The malfunction occurred due to instability of the power grid parameters.

If the consumer does not agree with the refusal of warranty repairs, he needs to order an independent examination and go to court with its results.

How to repair an electronic unit?

If the warranty period has expired, you will have to repair the control board at your own expense. You can try to cope on your own, or seek help from a specialist.. The second option should be preferred if the breakdown is serious, and there is no knowledge of the features of electronics.

Disassembling a household appliance

The control board in a Bosch washing machine is located under the cover of the device. The manufacturer placed it in the upper part so that it is not flooded with water and is not subject to excessive vibration.

To gain access to the module you need to do the following:

1. Turn off the power by unplugging the plug from the outlet.
2. Turn off the water supply tap.
3. Unscrew the top cover, which is secured with 2 screws. To access them, you need to move the machine away from the wall.
4. Remove the washing powder container.
5. Remove the screws holding the control panel. After this you can access the board.

Removal and diagnostics

The board is connected to the main components of the washing machine by wires.In order not to confuse the location of the terminals during the reinstallation process, it is better to photograph their correct connection. Then you need to disconnect the chips with wires, unscrew the 4 bolts holding the module, and remove it.

To begin with, the board is carefully inspected, checking whether the integrity of the wires is broken. Visually you can identify oxidized areas, soot zones, and mechanical damage.

If there are any, they are cleared out. Then you can move on to complex diagnostics.

This includes checking such elements as:

• capacitors;
• first and second order resistors;
• relay;
• diodes.

To diagnose the working parts of the board you will need a multimeter. Less often, a swollen capacitor or a broken solder connection can be detected during a standard inspection.

Troubleshooting Features

When starting to repair the control board of a Bosch washing machine, it is good to have its diagram before your eyes. It differs depending on the model of the device.

Troubleshooting Features:

1. If some elements are unsoldered, their connection to the board is restored.
2. Swollen capacitors are replaced. They are responsible for stabilizing the voltage, so they often fail during significant power surges.
3. Test the resistors with a multimeter. If there are deviations from the norm, they are changed.
4. If the trigger fails, then its contacts are resoldered.
5. The voltage on the thyristor unit should not exceed 12 Volts. If the values ​​are higher, the element needs to be replaced.

Sometimes all components of the board are working properly, but the washing machine does not work correctly. In such cases, a software reboot is required. To gain access, you will need a programmer adapter, the average cost of which is 3,000 rubles.

How to replace a part?

Bosch washing machine control boards are sold in online markets and in highly specialized stores. The cost of parts varies widely. The price depends on the complexity of the device of a particular model. The minimum cost of a component is about 3,000 rubles. The maximum price is 10,500 rubles.

At this point, photographs taken at the stage of removing the terminals with wires may be useful. If you connect them incorrectly, you can disrupt the performance of not only the board, but also that adjacent part.

Functionality check

To check the correct operation of a new or repaired module, you need to connect the machine to all communications.

Then you should start the wash cycle without loading laundry into the appliance. Recommended parameters for checking:

• program - cotton;
• spin – 1000 rpm;
• water temperature – 40 or 60 degrees.

If the machine is working properly, you can operate it as before.

Call the master

It is not always possible to repair the board on your own. Sometimes difficulties arise even at the stage of disassembling household appliances. If you don’t have the necessary knowledge and equipment, you should call a specialist.

Specialists advertise their services on the Internet and in print media. Sometimes word of mouth comes to the rescue. The cost of repairing the board of a Bosch washing machine starts from 2,600 rubles. The module will have to be purchased separately.

Causes and prevention of failure

The following factors can cause module failure:

1. A manufacturing defect.
2. Water gets on the board.
3. Unstable voltage in the network.
4. Violation of the integrity of the wires.
5. Improper operation of household appliances, for example, constant overloading of the machine.

To prevent part damage, You must follow simple rules:

1. Maintain a normal level of humidity in the bathroom.
2. Do not allow moisture to accumulate inside the device, for which purpose the hatch should be left ajar after washing and the cuff should be wiped with a dry cloth.
3. Use voltage stabilizers.
4. Follow the rules for operating and transporting household appliances.

Modern models of Bosch washing machines can be controlled using a smartphone. To prevent software failures, you should only use official applications from the developer.

Conclusion

The electronics of Bosch washing machines are of high quality, so they rarely fail. To prevent this from happening, you must follow the rules specified in the User Guide. If the module does break down, it is better to entrust its repair to specialists.
