How does a Bosch washing machine work?

Sometimes a washing machine needs to be repaired. In order to do this efficiently, it is useful to know how it works. Knowing the structure of a Bosch washing machine, you can disassemble and reassemble it, find out its strengths and weaknesses. As you gain experience, you can learn to repair your washing mashine yourself in almost all possible cases.

Main nodes

This device has many parts that belong to the following groups:

1. Those parts that relate to the control panel.

19. Mounting pins that fix the position of the hatch.
20. A handle that can be used to close the hatch through which laundry is loaded.
21. The mechanism that ensures the operation of the device that locks the hatch. If it malfunctions, it will be impossible to lock the hatch in the closed position.
22. Bushings that hold the hatch.
23. Front wall of the washing machine.
24. Fastening elements for holding the front panel.
25. A device designed to lock a hatch.
26. Upper spacer bar.
27. Bottom spacer bar.
28. Latches that are designed to secure the top panel of the Bosch washing machine.

Tank, drum and electrics

The main working parts of any such machine are the tank and the drum, as well as the electrics, which will ensure the operation of the washing machine in various modes. Bosch devices use the following parts:

1. A bolt that is designed to secure the drum pulley.
2. The large pulley for the drum is designed to transmit the rotation from the electric motor to the drum.
3. The back wall of the tank where laundry was loaded.
4. Bearings that allow the drum to rotate.
5. The drive belt connects the axle, which is rotated by the motor, and a pulley attached to the drum.
6. A stopper that stops the drum.
7. Metal drum together with a special cross with a bushing.
8. Large rubber seal for the tank.

10. The mechanism by which a counterweight is attached.
11. Bolts that provide reliable fastening of the electric motor of the washing machine.
12. Front engine mounts.
13. An electric motor that rotates the tank.
14. Electric motor brushes.
15. Rear engine mounts.
16. Stands for mounting the tank. They are designed for shock absorption, which dampens the rocking of the machine, which can occur due to the rapid rotation of the drum.
17. A mechanism designed to fix the heating element.
18. An element that heats water to the desired temperature.
19. Thermistor is a temperature sensor, based on the data of which water heating is controlled.
20. A clamp that is designed to secure the cuff.
21. Rubber cuff of the hatch.
22. Thin rubber gasket.
23. Front counterweight-stabilizer.
24. Front of the tank.
25. Springs that are designed to hang the tank.

Hydraulic system

This system is used to ensure that water enters the washing machine and waste water is drained. In addition, one of the tasks of hydraulics is to ensure the flow of washing powder and stir it. It also provides direct washing and rinsing of laundry.

The hydraulic system includes the following parts:

Design Features

One of the important features of Bosch machines is that its design is carefully thought out. During the design, the accumulated experience was taken into account and everything was done to ensure that the machines operated reliably and did not present difficulties during repair. One example of such models is Bosch max 5.

There are no overly complex parts in the design. With only a Phillips screwdriver and wrenches of the required sizes, you can almost completely disassemble the washing machine.

Another feature of devices of this brand is a durable hatch through which laundry is loaded. This chrome sunroof has double glass. It is almost impossible to accidentally damage it.

Conclusion

This brand is different not only quality and reliability, but also ease of disassembly. Knowing well the structure of the washing machine, you can confidently undertake repairs yourself.
