Bosch SPV50E0 dishwasher - standing water, cleaning lamp flashes

Hello forum members.

Unfortunately, my dishwasher refused to cooperate. The brush icon flashes to suggest that the filter space and the access to the pump vanes need to be cleaned. It is there without any reservations, the shoulder blades are loose. The dishwasher is humming when it is turned on, the water is pouring but unfortunately it does not run off.

And now either the pump does not work - how to check it?
Or it's stuck somewhere behind the pump.

Has anyone had a similar condition with this model? Any videos / instructions on how to disassemble the dishwasher?
Possible comments where and what to clean? How to choose the pump? What else can be dismantled apart from the drain hose?

greetings

It looks like the drain pump has failed. How to check it? Is there any way to run it dry or out of the dishwasher?

Below are some useful links for this dishwasher:

After dismantling the pump, you can connect to 230V or check the passage with a meter.
It often happens that as a result of blocking the pump, the thermal protection in the pump coil circuit is damaged, then there is no transition. The protection protects against temperature rise and against ignition.

You cannot test this pump with 230V, it is a three-phase pump. There are no thermal protections.
