Hi,
Anytime you replace a part on these newer dishwashers you always have to run the SERVICE DIAGNOSTICS CYCLE, and let it run all the way through to reset it back to default.
Entry sequence: Press any 3 keys in the sequence 1-2-3, 1-2-3, 1-2-3 with no more than 1 second between key presses. NOTE: Some models have replaced the “Clean” LED with “Completed.”
The Service Diagnostics Cycle will start when the door is closed.
--->Invoking Service Diagnostics clears all status and last run information from memory and restores defaults. It also forces the next cycle to be a sensor calibration cycle.
LET IT RUN ALL THE WAY THROUGH: Service diagnostic cycle will take about 23 minutes.
Do that, and report back if its working good again.
If not, and its not washing in the wash cycle, It's most likely a bad wash motor, this has become a common problem as of late, many members here have reported the same. In fact I had 2 this past Sept. 2018 in Parker, Arizona that did the exact same thing, and the new wash motor fixed them both.
Look at post #7 here:
FIXED 665.13472N411 What to check on why it only washes about 5% of the cycle.
I'd first check to see if your getting 120 volts to the wash motor when it should be in the wash cycle. His Kenmore 665 made by Whirlpool, and Whirlpool owns KitchenAid, and uses the exact same wash motor yours does.
Take the wire connector off the wash motor and use your multimeter to see if yours is getting 120 volts when it should be washing, if so and it's not running order the wash motor below.
Here's the wash motor assembly for you model:
