I picked up a non-working Samsung DW80M9960US dishwasher off Craigslist in September for $20 to learn how modern dishwashers work. My last dishwasher was a Bosch Evolution 800 series which is still working fine at over 20 years of age.

The Samsung had been given to the person selling it on Craigslist who gave up working on it. I was told that the waterwall motor was no good. Unfortunately, to get to the motor the prior owner broke one of the waterwall spray arms, lost all the screws holding the waterwall arms and the distributor/waterwall motor assembly, lost the microswitch and screw to the distributor motor.

I have the hardware, broken parts, and microswitch on order.

The Samsung turns on. It tries to move the waterwall vane. The vane moves to the rearmost position then stops. It then seems to try to move the vane to rear several more times even though the vane is already at the rear. Then it just goes quiet with no further sounds. The "power" button light, cycle LED, time display, and the LED that is under the door handle stays on.

I do have both the service and operating manuals but waiting for parts

This photo is of most of the parts for the waterwall spray assembly.

This is a close up showing that a leaking seal allowed water to fall on and enter the motor that drives the waterwall vane. The inside of the motor had been badly corroded.

This is what happens if you grab the nozzle assemblies to try to separate the two parts held together by a tab in the back. The top half with the distributor, the bottom half with the distributor motor and vane motor.

This photo shows the tab in the back. It can be very stubborn so releasing it takes some care since it is plastic.

Not sure how important preserving that tab is because the two parts are held together with four screws at the points shown by the red circles.

This photo shows the locking tab that is in the service manual to release the distributor motor/microswitch assembly.

What is not mentioned in the manual is that there is a second locking tab at the bottom of white plastic part that holds the distributor motor and microswitch that also has to be released.

The above link started by Robert Hiebert describes in words how a cam driven by the gear motor and the distributor valve need to be aligned.

"The valve has to be indexed to the cam correctly in order for the controller to correctly determine the position of the valve."

The photos below shows the parts being described above.

Here is an interesting video. Except for the door latch problem he is having all the problems I am having.

The leak occurs on the right side as shown below.

To examine why the leak occurs on the right side an experiment was done.

As the front of the waterwall was raised, the left side touches bottom first.

This lifts the right side up with the drive rail as the fulcrum.
