I have removed to drain pump, solenoid, water heater.
The drain pump white part spins with no obstruction at all.
With a multimeter:
My solenoid is about to get 984 OHMs resistance.
I’m not sure how to check my drain pump. I don’t see any connector end. Closest thing are these 6 metal spike thing pointed out on the motherboard.
I don’t see any visible blockage.
I’m not sure if I need to check the voltage as well. And do I need the dishwasher running for that. Problem is still stuff is located at the bottom of the dishwasher.

I bet it’s the back flow valve. Mine would try draining for a few seconds then error. Repeated rinse cycles would drain a little at a time. It’s past the pump in the out hose
Like the end with the white hose here?
984 Ohms seem kinda high for a solenoid, might be OK though, 700 to 820 ohms would seem more resonable. In the first picture there is a rolled up paper tucked under the inlet, carefully take that out and unroll it. That will be the schematic and field tech notes, it might have the solenoid nominal resistance values and probably has a trouble shooting procedure.
I’m not quiet sure how I would go about testing like that. And I never heard of working on a hot circuit.
I understand I could time the dishwasher and use that to help find what cycle it stops at.
These are the steps. It maybe stops somewhere between step 5.02 - 5.09
So thoses are “S” not 5 as in step 1, step 2, step 3, etc if you hook it back up and start the “Customer Service Program” per the instructions at the top of the page the display will read out the step its on, it will do that step for the time indicated in thee 3rd column and it will be doing the action indicated in the last column, then it will move on to the next step. This allowes you to watch and listen to each step to make sure its doing what it should. Find one that is not and you probably IDed the issue.
To steps it says to use special function menu mentions button I do not have.
I tried asking AI, and it mentioned holding left arrow plus right arrow, then turning to changing on, and clean should flash multiple LEDs.
Delicate wash flashes and express wash stays lit when doing this. Then pressing start lights both those LEDs. Then press start again, I can hear something clicking twice, then the active and clean LEDs flash including delicate and express wash.
And if I try doing a normal wash. Some thing but the sanitise light flashes. And no water this time
The buttons aren’t labeled on the front of your machine as A B or C. But A is the button furthest to the left, B is the middle button, and C is the button on the right. Post a pic of the front of the machine with the controls or post the make and model.
Hmmm, looks like the tech sheet you have is for a dishwasher that has a 3 digit 7 segment display. Odd that it would have the wrong sheet. This looks like thee correct version for your model, follow the steps that say for shx (the first part of your model number).
Oh thank you. I understand better now.
The active and clean light are flashing which the others person shared from their diagram that it could be to drain pump.

This might be the LED to service modes that can apply to yours.

I THINK this is for your model
Those two flashing complains about the drain pump. Another comment I saw showed the drain pump cover not being pressed down all the way until it clicks in can cause it.
I can’t find the actual repair manual for that model though to decode the menu options for the service mode. Another similar display less model probably has the same meanings for the flashing LED lights. Their UI is atrocious.
Water inlet valve here shows 990-995 Ohms
As I suspected this has your resistance measurements for each of the motors, so measure where indicated (power disconected) and you can see if the windings in the motor is faulty. Your selonoid value looks good.
