My dishwasher fills then never actually runs. Then drains after not running for a while. I get the error code f6 e4 when I run the diagnostic mode. Based on what I read I tried replacing the overfill switch under the dishwasher and the control board inside the door. The problem has persisted. There is a small clicking when it's not running. Any ideas?

Thank you so much in advance for any help.

Yes, 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 do this same thing in Sept. 2018 in Parker, Arizona, 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 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 is the wash motor assembly for your model:
W11032770 Motor-Pump


Here's the video:

Or, you can order the complete assembly which comes with the wash motor already installed for you along with a new diverter motor too that's less expensive:
PUMP&MOTOR WPW10605057


Let us know what you find.
