No water, no nothing...just the humming noise.

Something to do with the starter sequence? Door latch? Timer motor?
WTF?

I'm a software guy, not an appliance repairman, but
I think the water has to fill enough to raise the internal
float switch before the rest of the cycle can run.

I would suspect the electrically controlled valve
that turns the water on and off.

If there's voltage to the water valve but no water,
replace the valve. No voltage to the valve, work
backwards from there.

Thanks for the replies, I found this:

GE - Hotpoint, McClary, Moffat style dishwasher just hums (some
Kenmore, Jenn-Air ): If this style of a dishwasher sits unused for a
period of time the seals in the motor and pump can get frozen together.
Sometimes high minerals in the water also can stick the seals together
and the motor cannot turn on, often the dishwasher will fill with water
and just sit there "humming". Usually this is fairly easy to repair and
get going again. Remove power and access panels....reach in with your
hand and turn the cooling fan blade a turn to break it free, reinstall
power and try the unit. If this "sticking" keeps reoccurring, the motor
and pump assembly will probably need to be replaced.

So I am going to check out the motor...while I am down there I will
check for things that might be sticking as well.

I don't mind buying another dw if I have too, but I will feel better if
I can fix it.
