You’ve started a wash cycle, and when you come to pick up the laundry, you find that the Bosch doesn’t wring it out. There may be an error on the display.
Possible malfunctions requiring repair
If none of the above situations are similar to yours, your Bosch has probably failed. Lack of spin in the machines of this brand is most often associated with malfunctions of the following nodes.
1. Fraying of motor brushes
Brushes are responsible for transferring voltage from the stator to the rotor. If they are shortened, the power of the motor decreases, and Bosch cannot reach high revolutions. As a consequence, there is no spin.
If you continue to use the machine, as the brushes continue to wear, the drum will stop spinning at all.
2. drive belt is broken, stretched, or collapsed
The belt normally transmits the rotation of the motor shaft to the drum. If the belt is stretched and slipping, the Bosch washing machine cannot gain spin speed and will not spin. If the belt is loose or torn, then the drum does not rotate at all, although the washing program is running.
3. Bearing destruction.
The bearings are responsible for the smooth rotation of the drum. Unfortunately, under the influence of vibration, the packing loses its tightness, and through it the moisture enters the bearings. As a result, they are destroyed by corrosion.
If the bearings are even crumbling, the drum may jam.
4. Faulty control module, which is responsible for the operation of the entire washing machine
Probably on the control board failed individual radio components or burned out tracks in the circuit of the motor.
5. Failure of the tachometer, the node that is responsible for determining the speed of the machine’s engine
Due to the breakage of the tachometer, the control board can not determine the speed of rotation of the drum and interrupts the washing cycle.
6. Wear the shock absorbers
Normally, most of the vibrations of the washing machine are dampened by shock absorbers. When they wear out, the vibrations increase, so because of the imbalance the machine can not reach high speed.
7. Faulty pressostat – a sensor that determines the level of water in the tank
It is stuck in the “full tank” position. This happened because of a clogged pressure chamber, pressostat hose, or a malfunction of the sensor itself.
8. Foreign object in the tank
It is not uncommon for small pieces of hardware (“bones” from a bra, “tongues” from zippers, rivets, etc.) to get into the tank and prevent normal rotation of the drum.
9. Engine failure
The motor of the washing machine is its main driving force. If there was a short circuit or breakage of windings, the motor does not work, and the machine does not rotate the drum.
10. Damaged wiring or contacts in motor or tachogenerator circuit.
The vibrations have frayed the wiring or the contacts have oxidized/burned through due to moisture.
Mice and rats often chew through the wiring in dachas.
