Whirlpool Dishwasher won't run

[Ron77]

Hi, we have a whirlpool model DU8500xx dishwasher. It stopped the other day midcycle. Just nothing, no sound. Here is what I've checked so far, any other ideas?

Power is coming in to the unit.
I disassembled the door to get at the door switch and timer motor, etc. The door switch is working perfect, there is voltage on the timer selector. If I test the leads going out of the timer, to the selector switches, I can see the voltages changes as I rotate the rotary dial.
There is voltage to the motor relay, but I'm not sure if it's working or not

Now I'm lost, thanks for any advice :)

anyone?

More info. I did some more testing. I 'think' the motor relay is working. I test all 3 posts of it based on frame ground. With the door open, there was no juice, but with the door closed, all three terminals jumped to 110 volts. I then checked the voltage to the main motor and there was about 40v doing to it.

Ideas?

Can you advance the timer to the next cycle and see if the washer kicks in?

I found this great detailed site for checking all of your dishwasher parts.
