I had the h20 error, cleaned the pressure valve and now it runs.. but doesn't run full cycle.

You mean the pressure switch as I mentioned here:

Can you tell which motor it is? You have a drain motor and wash(circulation) motor. Notice when it does that, if the dishwasher is in the wash cycle or drain cycle.

It wasn't the switch, it was the one that connects to the drain from the bottom I took out and cleaned it, I got 2 full cycles after that. While I'm hoping it is fixed, I'm guessing it's lucky.

YOU DID ALL THIS BELOW?

Yes, Disconnect power to the dishwasher, then pull the pressure sensor out and clean it and see if the fixes it.

Look at my post #3 here:

FIXED - GDT665SMN0ES Starts, drains, and times out/stops 56 Error Code

Our GE GDT665SMN0ES (~2 years old) will startup and drain (I replaced the drain pump, and I can hear it drain). Then it sounds like something is running, drain or water, and then it just shuts off. It does this for all cycles. When I go in to the diagnostics I see Error Code 56. Then when I...

Its usually the pressure sensor that is the problem, so cleaning it should fix it, if it works and starts happening again, order a new pressure sensor.

 

[jander76]

Yeah this is what I did exactly! I have mixed results on cycles so I'll start with replacing it regardless. After that would you suggest the inlet valve potentially?

Yes.
