Dishwasher Circ. Pump Not Working - Kenmore 665.16039403 - Tech Sheet Needed

[randy88k5]

I am trying to fix my Kenmore dishwasher.  The circulation pump is not turning on.  The rest of the functions of the dishwasher work fine.

I removed the circulation pump and bench tested it.  It ran fine with no noise.

I checked continuity of the wires going from the control board to the circ. pump and all were continuous.

Does someone have a tech sheet for this (or something similar)?  I need the wiring diagram to continue diagnosing.  There is no sheet behind the kick plate or door skin.

Thank you.

Pretty simple to diagnose.  Whirlpool is known for failed wash pumps, and this is a whirlpool. It can fail intermittently.  Reassemble the machine if you haven't already, pull the connector off the wash motor,  stick a meter on it preferably set to LoZ if the meter has it, run a test cycle, after it fills you should get ~120vac at the harness.  If you do, replace the motor, if you don't,  replace the board

Robin,

Thank you for the tips.  I reassembled and ran a test cycle.  I saw the 120v coming from the board.  I paused, and hooked it back to the wash pump.  The pump then came on as normal.  I'll be replacing the motor.  Thanks again.

No problem
