Whirlpool ADG 8967 IX Dishwasher - Ineffective Washing and F8 Error Occurrence

Hello all.
I have a Whirlpool dishwasher ADG 8967 IX, type NGPH
Numbers: Service: 8542 967 10780, SER: 33 0511 017089

The problem is that when I turn on the dishwasher it gets water (I have the impression that less than before, but unfortunately I'm not sure), then nothing happens (the dishwasher is not washed effectively), and after some time the dishwasher releases water and ends the program . Today I pulled her out, I gave her to the chairs and watched more closely. I started the 40 '30 minute program and the dishwasher looked as follows:
- the dishwasher has picked up water
- later the water automatically "merged" (the dishwasher was on chairs, so it probably resulted from gravity)
- nothing happened and after a few minutes the remaining water was drained away
- water has been poured again
- washing did not start again
- the water was drained again
- the cycle has been repeated again with the difference that finally the F8 error occurred

I was looking for a forum and from various descriptions it would appear that the problem is with the washing pump.

Do my symptoms really indicate a problem with this pump? If so, how to remove it (photo of the dishwasher "from below" below)? After dismounting, can it be checked if it is actually broken?
What do you advise in my case?
Thanks in advance for all the help.

Thanks for the help
I will do as you suggest and let me know if it helped

Hello,

Today I watched the dishwasher a little more accurately and my additional observations:
- the heater works because the water during the cycle was warm
- something tries to work during the cycle, because the water in the dishwasher moves (arrow indicated in which place you can see it) and you hear sounds like some kind of pump. Any suggestions?

Hello everyone again,
Do you have any suggestions what could cause problems with my dishwasher? Is this still pointing to a broken pump? Thanks in advance for all suggestions and advice.

Check for delamination of the wash arms.

>>17328056 K týmto motorom čerpadiel sú pripojené kondenzátory 2 až 4uF . Už som sa stretol s viacerými , že tieto kondenzátory boli suché -nemali kapacitu . Po výmene kondenzátora , všetko funguje normálne.

>>17328056 V odborných servisoch často menia celé čerpadlo . A stačí len vymeniť kondenzátor za 2€.
