The machine will fill and stop. The timer will cycle through to the end, but there is no function, no motor noise, etc.
There is just a tick tock clicking noise in the door panel every couple minutes.
At the end the CLEAN and Keypad 2 lights will blink steadily.
The wiring harness in the door was recently replaced by Maytag under a recall.
When I try the DRAIN/Off button the display shows cycle time and I can hear a relay clicking on the circuitboard in the door controls, but the pump motor does not come on.
I suspect maybe a failed relay on the circuit board or failed motor. There is some (heat) discoloration near two resistors on the cicuit board.
The motor armature spins easily (not jammed).
Any ideas?

Remove the bottom panel and check if the power is coming to the motor. If there is power then replace the pump & motor assembly. If there is no power then the control board has to be replaced. - The part number for the control board AP3158621 To find the right part number for the pump & motor assembly I need you to post the serial number of the dishwasher. - Here are the break down diagrams for the Maytag dishwasher Model MDB7100AWWGene.

Thanks for your prompt reply, Gene.
If I unplug the lead to the motor and check there?
If I read the diagram correctly....
At the start of the cycle, after fill, I should expect power across BU and GY leads?(WASH)
S/N is 15899926yu

You can do the motor continuity test. From BU to all others suppose to be some resistance. If any of the motor winding is open - the motor is bad. The power should come to the main winding as well as to the wash (BU & GY and BU & Y). - The part number for the pump & motor assembly AP403850 Gene.

Thank you, Gene.
You were absolutely correct!
No power at the motor plug-at either winding.
So, I went to the board. Figured I had nothing to lose, so I removed the cover of the power relay.
The points supports had warped enough that the contacts couldn't close.
I just bent the support a little, and voila!
No more dishpan hands!
Thanks again! I will keep you in mind when it really croaks.
