Looked up the replacement part on YouTube, watched a video and followed the instructions. Part ordered was the correct part and the video showed how to access for replacing. Watched a different video for hooking up the disconnected springs that allow the door to lower and close smoothly. Whole process for repairs was less than 30 minutes.

A quick twist of the locking nut

Replaced latch

Pulled dishwasher out switch is on very bottom of pump housing, turned dishwasher on its back, took out 1/4" bolt holding on bottom of switch frame, took two very small screwdrivers and small picks to hold open switch clips, while switch was removed checked float for frew movement, put in new switch, removed screw drivers and picks checked to see all locked on new switch in position, replaced bottom plate and bolt, checked burner reset all good now dishwasher heats and drys!

Pretty easy repair, since I installed the DW, so knew how it went in,
turn off breaker, shut off & disconnect water, disconnect drain line into disposal, siphoned water out of bottom collection basin below sump filter.
Slid DW out from under counter & laid on it's side.

Glad I watched a YouTube video so I knew to pry open 1 of 2 crimp style hose clamps on the old drain pump, then made sense why this was a drain pump "kit" that included 4 or 5 standard band hose clamps.

took off 2 sheet metal on the bottom, lowered the dish washer, pulled it out enought to unscrew 2 screws, unplugged the old part plugged in the new, put it back together.
Works like a champ.

After hours looking for problem. I tried cleaning door gasket. Did not stop leak. Looked at lower water spray arm and it was split. It is literally a 2 minute repair to remove and install. Knock on wood, no leaks in the last 10 washes.

Removed the top two screws that hold the dishwasher to the cabinet , remove the two screws on the bottom panel and remove the panel. Screw the levelers all of the way up and pull out the dishwasher about 6 to 8 inch. Hook the new cabe on the spring and pull around pulley and attach it to the door bracket. I replaced both cables. Reverse to complete.

Followed video instructions step by step.
I was fortunate i had enough slack in water, electric and discharge lines to avoid disconnecting.

Two wrinkles
1. wire clips on my door had to be pulled/pried loose from door and there were two not one

2. could not slide dishwasher out after lowering adjusters and figured out it was the mounting tabs bumpimng the granite countertop, thus the use of putty knives to slide the dishwasher out.

Super easy repair, just removed the old latch and replaced it with the new one.

The Mid Spray Arm Assembly was not spinning due to a dish that was in placed the dishwasher that was too high and hitting the arm. When it spun until it broke the center shaft. Replacement was easy. After removing power I pulled the upper tray out and removed the Conduit Mid Tiered Assembly by unsnapping it from the tray. I twisted off the broken spindle of the damaged arm assembly from the Conduit Mid Tiered Assembly and inserted the new arm and gently pushed it until it snapped into the Mid Tiered Assembly. Reinstalled the assembled parts by snapping into the tray making sure it was centered.

The old gasket pulled right out with no tools needed,
The new gasket went in the same way.

Results:
It did help on one side, but the bottom gasket also needs to be replaced it has a couple of tears one on each end.

Next Steps:
When the bottom gasket gets here I will replace that and it should be as good as new.

The base of the spray arm literally just spins a little bit into place like a luer lock. Takes two seconds to replace.

Took off the door and separated the two door pieces. Unscrewed the old dispenser and replaced it with the new one.
