Whirlpool ADG 6500 Dishwasher Error: LED Blinks 6 Times - Cycle, Potential Causes & Fixes

Hello
The dishwasher starts for a few minutes and crashes an error. The cycle is as follows:
- pumps out residual water
- pour a new portion of water
- the washing pump starts and you can hear the sprinklers working for several seconds
- the sprinkler pump stops
- draining residual water
- the dishwasher squeaks and displays an error (6 blinks of the LED)

I checked the reed switch - it works
The pumps are working
Filters clean, water pressure after unplugging the hose is approx.
The dishwasher looks very simple and I do not see that it has a membrane sensor or OWI. I also did not locate the water jet divider (which surprises me because it has a half load program).
I wonder how the dishwasher knows that something is wrong (from which sensor it gets information about the error with the water supply)
Please give me some suggestions what I can check.
I attach photos of the inside of the dishwasher

Wash pump to be replaced. The rotor sleeves are worn, the pump current has increased during operation and the electronics stops the operation of the device. These dishwashers are mean in that regard. You can still substitute the pump's starting capacitor in a gesture of despair, but it will certainly do nothing.

Ok, I'll check it out today.
I understand that the pump impeller is to have 0 radial play, while the axial play is acceptable.
