What is the meaning of error E2 on a Bosch washing machine, how to detect the problem and fix it?

Modern washing equipment is equipped with a self-diagnosis function. If faulty situations occur, information about the occurrence of an abnormal situation is displayed on the display in the form of a specific code.

In Bosch washing machines, one of the error messages is E2. To restore the operation of the device, you will need to diagnose the condition of the equipment and repair it.

Decoding the code that the Bosch washing machine produces

Error E2 (or E02) in Bosch washing machines means there is a problem with the engine. The issuance of this encoding is accompanied by a stop in operation if the washing cycle has already begun, or a complete failure to start the motor.

In Bosh machines without a display, a malfunction is indicated by the lighting of three indicators that are associated with the spin cycle: the top one (maximum spin), the middle one, and “no spin.” In very old models of washing machines with a display, an error related to the motor may be indicated by code F21.

Causes and solutions to the problem

If the problem with E2 arose for the first time, there is a chance that it was caused by a random combination of circumstances.

To resolve the issue, you can first reboot:

1. Turn off the washing machine (pull out the plug from the socket).
2. Wait 20-30 minutes.
3. Restart.

If the situation with the E2 code being displayed on the display repeats immediately or after a while, the problem should not be started. The fault must be diagnosed and corrected immediately. Before this, you should not use a Bosch automatic washing machine.

Engine brush wear

In the electric motor of a Bosh washing machine there are two carbon brushes. They are used to transmit current to the rotating armature of the motor. Graphite is a good conductor and has lubricating properties, which ensures high-quality sliding.

With prolonged use of the washing machine, the brushes wear out and lose their functionality. As a result, the washing machine motor stops.

The following signs may indicate wear:

• an uncharacteristic noise is heard when the engine is running and sparks are even visible from under the washing machine body;
• The drum does not spin, but water is drawn in and drained without problems.

According to statistics, brush wear is the most common cause of E2.

To repair, the engine must be removed:

1. First, carefully remove the drive belt.
2. Disconnect the supply wires.
3. Unscrew the screws holding the engine.
4. The engine itself is removed.
5. Squeeze out the brush contacts.
6. Remove the brushes.
7. Install new ones.
8. Reassemble in reverse order.

Brushes are replaced two at a time, regardless of whether they are equally worn.

Bearing failure

A problem with bearings is accompanied by noise and knocking when spinning clothes.. Additionally, leakage may occur due to water entering the rotor bearing. Replacing the bearing can solve the problem. The final decision is made after inspecting the parts and determining their condition.

The procedure for replacing bearings can be found in the video:

Rotor axis deformation

Deformation of the rotor axis is not a rare problem. Such a violation may be accompanied by a strong noise, uncharacteristic of the normal operation of the Bosh washing machine, when the motor is running. Replacing the rotor will help solve the problem.

The tachometer is broken

The tachometer is an element of a Bosch washing machine that controls drum rotation speed. If the sensor breaks down, the drum may spin at first excessively quickly, and then stop, displaying E02 on the display. To perform diagnostics, the Bosh washing machine is de-energized and partially disassembled.

Engine failure

To analyze the performance, the engine is dismantled. After this, using a multimeter, test. If the engine burns out, it is replaced with a new one.

Control unit malfunction

In rare cases, code E2 may indicate a breakdown in the Bosh control module. To analyze the condition, the unit is removed from the washing machine, having first disconnected all the wires.

Most often the problem is solved by repair, but if the unit is severely burnt out, even a complete replacement may be necessary.

If you have no experience working with electronics, it is advisable to entrust the repair of the control unit to a specialist.

Wiring violations

A rare but possible situation where E2 may appear is a wiring fault.This error can be caused by either damaged wires or loose terminals. As a result, contact becomes intermittent and the washing machine may become unstable or stop working completely.

To find the damaged area, it is necessary to sequentially inspect the condition of the wires. If possible, do a twist. In case of serious damage, replace it with a whole cable.

Call the master

It is not always possible to deal with breakdowns of a Bosh washing machine on your own. Very often the problem is so serious that it is better to entrust its solution to a specialized specialist. In this case, you need to call a technician from a company that repairs washing equipment in the city.

You can find such a company on the Internet. Companies that provide their services with high quality have positive reviews and value their reputation. The cost of work when calling a specialist depends on the complexity of the breakdown and the company’s price list.

The average prices in Moscow are as follows:

• replacement of motor brushes – from RUB 1,800;
• repair of the control module – from 2,000 rubles;
• replacement of bearings – from 4,000 rubles;
• motor replacement – ​​from RUB 2,500.

Prevention methods

Repairing or replacing a Bosh motor is a serious breakdown that is very expensive to fix. To avoid such a problem, Preventive measures can be used:

1. The cause of combustion of the motor, block and other elements is often a voltage drop in the electrical network.

   To protect your washing machine, it is advisable to install a voltage stabilizer and connect the washing machine only through it.

2. One of the factors that shortens the service life of equipment is its constant presence in unsuitable conditions, for example, in a room with high humidity. If the washing machine is installed in the bathroom, it is necessary to ensure good ventilation in this room.
3. Increased vibration also accelerates wear of components. When the washing machine is installed correctly, the vibration amplitude is within acceptable limits. But if the floor is uneven, the machine is not level, and the drum is often overloaded, wear will occur faster.

Recommendations

When the Bosch code E02 appears on the display The following tips may be useful:

1. To analyze the condition of the motor, in any case, you must first remove it from the washing machine.
2. The selection of spare parts should be made taking into account the model of the washing machine.
3. To disassemble the washing machine, diagnose and repair, you will need a set of keys and screwdrivers, pliers, and a multimeter.
4. When removing the motor brushes, you need to remember (take a photo) in what position they were originally.

Conclusion

Error E2 on Bosch washing machines does not always indicate a serious breakdown. But if a simple reboot does not help to get out of the situation, diagnostics and repairs will be required by opening the case. Dealing with a Bosh motor without experience can be quite difficult, so in such cases it is better to call a specialist.
