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.

984 Ohms seem way high for a solenoid, 8 to 20 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 prkcedure.

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 and you can see if the windings in the motor is faulty. Your selonoid value looks good.

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.

AFAIK you would need a VFD or a custom built driver circuit to generate the frequency you need to operate it at which is the hard part.
Honestly though if it’s an permanent magnet synchronous AC motor (highly likely) you should be able to test it provided you had a Variac to lower mains voltage (or transformer with taps works too) although you would need to bring the input voltage waaay down.
Permanent magnet synchronous motors have a ratio of V/Hz you need to maintain, in this case we have 0.256 V/Hz.
To test at 60Hz the max I would start at would be 15.34V AC at 60Hz. Otherwise you draw too much current and risk cooking it.

These are the steps. It maybe stops somewhere between step 5.02 - 5.09 Image

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 Cycle” perf thee 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 2nd 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.
