Works loudly, hum smv68ix00e ⇐ Bosch

[Rew1s]

Good afternoon, I have encountered a problem. When the dishwasher is operating, a fairly loud hum of operation is heard, low-frequency, similar to the operation of a drill in the next apartment (not very loud, but unpleasant)
The sound comes from the bottom right of the dishwasher.
I did all the basic things that could be done before disassembling the dishwasher. I made sure that nothing was knocking inside, checked the filter, everything was clean. I ran the machine with somat cleaning agent.

It washes perfectly. There are no errors.

Since I bought it secondhand, I don’t know how it worked before. But I’m sure it should be quieter. The machine is 4 years old.

Where is the problem most likely to be? Could this be, for example, due to wear on the pump? and What is the probability that it is the motor itself?

Thank you!

This happens when a mechanism malfunctions. If the noise stops after closing the water tap, then the problem lies in a faulty inlet valve.

For some reason I have a suspicion that this may be a problem with the bushings of the circulation pump, the only question is that this sound occurs throughout the entire washing cycle. Does the circulation pump work throughout the entire wash?
In any case, today or tomorrow they will disassemble the machine and see what’s there
