How to determine what needs to be changed?
Despite the high reliability of Bosch washing machines, problems may arise during operation due to a loose or worn belt. Washing machines do not have an exact sign that would clearly indicate this problem.
But there are also situations in which the washing machine does not detect problems, especially when they are just emerging.
About the problem with the Bosch belt The following signs may indicate:
after starting work, the motor does not emit the usual hum, but if the drum is pumped by hand, it will move freely;- when the wash has started and the motor is humming, the drum does not spin, and the washing machine does not respond to pressing the buttons;
- the motor starts to work, but after a while it quiets down;
- The washing machine has filled with water, you can hear the sound of the motor running, but the drum does not start rotating.
If the user notices any of the listed “symptoms,” you must turn off the Bosch washing machine. If the belt falls off or breaks, the engine idles, without the planned load. This is highly undesirable, as it can lead to overheating of the motor and serious damage.
One of the reasons why the belt may break is if the washing machine is left idle for a long time without use.
Preparation
To check the condition of the belt, you need to see it. To do this, the Bosch washing machine must be partially disassembled. But first you need to turn off the power to the washing machine (not just turn it off, but pull the plug out of the socket) and turn off the water supply. If there are things left in the drum, they need to be taken out.
After this, the Bosch washing machine is pulled out so as to gain access to its rear wall. This panel must be removed using tools.
In normal condition, the belt covers the motor pulley and the large pulley that is located on the tank. It should be in a taut state.
If a part has come off and is just lying there, it can be put back in place. But this technique can only be used when the jump occurred for the first time, and it does not have obvious defects. Otherwise, the part will require replacement.
Even a damaged (broken) belt should not be thrown away immediately. There is a marking on it that will help you make a choice when purchasing a new replacement product.
How to remove and replace?
If the belt comes off on its own, it is simply pulled out of the washer. But if it's still on the pulley, it must be removed by turning the wheel by hand. If the part has weak tension on the pulley, it becomes ineffective, in which case it may spin. As a result, the drum does not receive proper movement, and the washing process does not complete.
Putting a new belt on a pulley can be quite difficult. The best option is to ask someone to help. One person can make sure that the belt does not come off the motor, while another person will pull it onto the large pulley.
How to put on a belt:
- The new part is first put on the Bosch motor pulley.
- Slowly, turning the pulley wheel on the drum, pull the rubber belt onto it. At the same time, you should check that it does not jump off the motor.
- Check for correct placement.
- Rotate the drum pulley several times.
If after installation, at the stage of turning the pulley, you feel the belt tension, then the work was done correctly.
Next you need:
- Install the back panel.
- Secure the back panel with screws.
- Return the washing machine to its original place.
- Connect all communications.

Repeated jumping: searching for the cause
If this is not the first time that the belt has jumped off a Bosch washing machine, and both new and old parts have done this, you should more carefully inspect all the components of the washing machine involved in the operation.
The reason could be one of the following situations:
| Problem | Ways to solve the problem |
| Incorrect belt installation | The belt has a relief that provides better transmission of driving force from the motor to the drum. If installed incorrectly, the ring does not fit into the grooves and may spontaneously jump off during operation. |
| Loosening of bearings during long-term operation | Worn parts can disrupt the belt drive and cause the belt to slip off. Bearings need to be replaced |
| Damage to the cross | This is a rare but possible problem. Most often this is a manufacturing defect or strong vibration during spinning. Part replacement required |
| Pulley or shaft deformation | It is almost impossible to straighten a deformed part. Exit - installing a new part |
| A breakdown of the motor that causes it to work harder, spinning more than it should. | Engine repair/replacement |
| Frequent drum overload | If the drum is frequently overloaded, the belt may fly off the pulley due to excessive vibration |
| Weak fixation of the motor in the socket | During prolonged use, the fasteners may become loose. The solution is to check the fasteners and secure the engine well |
| Drum play | If the drum moves unevenly, the belt may fall off. Repair involves tightening the pulley mounting bolt. But sometimes it may be necessary to replace a deformed wheel |
