HI !!! New Guy Here. Diagnosing a Whirlpool DU915PWSQ0. Detergent not dispensing. Thought it was the Wax Motor. Replaced and still nothing. Prior to Replacement of Wax Motor all mechanics working properly. Lid closes and opens smoothly. Springs Open Smoothly. The assembly that the Wax Motor Pushes or Pulls the Door Latch functions properly when I move it manually. Guess i'm just hoping its the Control Board. Any help would be greatly appreciated.

Here are your parts
Parts for Whirlpool DU915PWSQ0 Dishwasher - AppliancePartsPros.com

See the attachment for the tech sheet.

Check the new assembly wax motors with a meter.
It would not be the first time that a replacement part was bad straight out of the box from the manufacturer.
Check the wiring to/fro the dispenser with a meter.

If all the above is OK then I agree with you that it is probably the control board.

The Wax Motor has 3 wires but don't know which ones to test, what to setting to test it on or what they should read (Resistance,Ohms ?) What kind of readings should I get coming out of the Harness ?

OR-BK (orange and black) - detergent motor - 600 to 1800 ohms
