1 What does the error E02 mean: options for eliminatingmechanism is possible. To do this, do the following: - Check whether there is sufficient mains voltage to operate the CM Bosch. If not, you may need the help of an electrician.
- Disconnect the machine from the network for 15-20 minutes. If, after a reboot, the error E02 is cleared, then the reason was a failure of the electronic controller.
If the recommendations did not help to remove the error, then proceed to search for damage and repair parts.
Causes of breakage and repair
Motor is an important detail in the washing machine. Thanks to his work, the drum rotates during washing. Therefore, if you do not solve the problem, you will not be able to use the CM in the future.
However, the cause of failure may not lie in the engine itself.
Brush wear
80% of the breakdowns when issuing an E02 error is due to the carbon brushes of the electric motor.
Over time, they wear out, as a result, the motor stops. What signs may indicate wear of the brushes:
- The washing machine, as always, collects and drains water, but the drum does not spin.
- You hear the noise and notice the sparks under the Bosch washing machine.
How to troubleshoot if the error E02 is lit:
- Disconnect the washer from the network.
- Disassemble the Bosch washing machine.
- The engine is located below, under the drum.
- Remove the drive belt and disconnect the engine wires.
- Remove the screws that secure the motor.
- Remove the engine, wring out the contacts of the carbon brushes.
- Remove the brushes. Check: if they are almost or completely worn out, they need to be replaced.
Defective rotor bearing
If you hear noise when spinning clothes or notice a leak in the tank, this is caused by water that has entered the rotor bearing.
What to do to solve the problem and reset the error:
- Install a new electric motor in the Bosch washing machine.
- Remove the engine, remove the rotor. Remove the protective cover from the bearings. After cleaning and processing, lubricate the bearing.
- Completely replace the bearing.
A fairly common failure is the deformation of the rotor axis. In this case, the user can hear the rumbling sounds as the motor rotates.
A new rotor must be installed.
The failure of the tachometer
The tachometer - Hall sensor - controls the speed of rotation of the drum.
What signs indicate a tachogenerator malfunction: the drum turns abnormally fast, then stops, gives an error Е02.
If you notice this "behavior" at the Bosch washing machine, then you need to check the tachometer with a multimeter. Normal is the resistance in the range of 70 ohms - the device is working properly. If the device is broken, it must be replaced.
The last thing to check is the engine itself. This will help you tester multimeter, whose performance should normally be from 1 to 7 ohms.
If you need to replace the motor, you will be helped by the video:
Very rarely a fault code is displayed due to a break in the control module. However, if you have eliminated all other faults, check the module.
. Replacement of the unit or repair of the board may be required. Before removing the problem, consider whether you can cope with the repair yourself. If so, follow our recommendations.
