Hi everyone!
I've recently acquired a nice KitchenAid by Hobart KD-12 dishwasher and want to install it. My only question is I have new electrical coming into my current modern dishwasher but in the KitchenAid it only appears to be one wire to run the motor. Just wondering if anyone has any helpful hints or pointers for me before I try to tackle this project?

Thanks in advance!

Use the link below to access a downloadable KD-12 service manual for a nominal fee.  It should provide information on the wiring in question.

Single motor wire?

What you may be seeing from the motor is what looks like a single wire, but is like a black covered wire set containing a single white and single black wire enclosed by the black covering. Motors need a positive and neutral wire to operate. (There may also be a grounding wire for the motor in that casing as well.)
The black wire from the motor should go to the timer terminal marked "P" for pump and the neutral white wire should go to the terminal block located on the cross
member of the frame in front. The incoming power from the house gets connected to that terminal block with the hot side going to the terminal with the black wires and the neutral going to the terminal with the white wires. Also, the ground wire from the house should go to the grounding lug on the cross member or on the terminal block if a spot is provided for it there. It has been a VERY long time since I played with one of those machines. Mine was a KDP-12P Portable unit with pumped drain. The service manual should help you figure it out too.
