Shuts off just after starting cycle

Dishwasher Repair
1

Brand:LG
Model Number: LDTH7972S
Main Symptom: Shuts off right after cycle start
What happens & when: at first i noticed it shutting off mid cycle about 20 minutes in. i leaned on the door and started a cycle and stayed leaning on it and it completed the 1 hour cycle. so i figured it was the latch. Got the latch today and replaced it. Now it shuts off right after starting the cycle weather i lean on the door or not has no effect change. its seeming like initially leaning on the door and having it complete the cycle was just a coincidence.

i changed the latch back to the old one and this current problem persists so im assuming both latches are good.

any tips or some sort of direction for testing would be appreciated.

Error Code (if any): i wish
Parts or tests already tried: new latch

I would suspect first some wiring issues inside the door. Take the door cover off and run it, wiggle some wires and see if you can locate possible a bad connection at the interface, latch area.
