For many weeks, our dishwasher has been making a fairly loud higher-pitched whistle/whine for the first few minutes of the wash cycle. The tone is steady in pitch and intensity though sometimes a second tone (close in pitch to the first) appears as well. After a few minutes, all tones fade out and the dishwasher functions normally without any further glitches.
Yesterday, the dishwasher would not start AT ALL. A couple of function indicator LEDs on the touch panel were illuminated. Pressing the START button had no effect aside from changing the pattern of LEDs (I believe a couple flashed on and off about 5 times, that was it.)
I cut power to the dishwasher overnight via the wall switch wired to unit.
This morning, I re-applied power. I closed the dishwasher door. The LED above the CANCEL button was illuminated (steady). I pushed CANCEL and a few moments later, the usual front (touch) panel indicator LEDs illuminated. By usual, I mean the lights that indicate which cycle and options have been selected. In my case, it's 'anti-bacteria' (water heating), 'normal', 'energy saver dry', etc.
I pushed the START button and the dishwasher sprang to life, and began washing "normally"; - high-pitched squeal and all.
However, about 25-30 minutes into the cycle, the thing quit and all the touch panel indicator LEDs went out. Bizarre!
My quick research suggested that replacing the motor assembly would 'cure' the noise problem but now I'm wondering if there is a second problem.
The control panel has been replaced once before - I know they do sometimes fail but I am just not sure that is the problem.
What repair strategy would you suggest? I am not averse to spending $200-$350 in parts as this was one of KitchenAid's higher-end machines. Besides the control panel and the motor/wash arm assembly, what else would really go wrong with the machine?

A high pitched noise sounds like a bearing in motor or transmission. Doubt there's a belt, which could also make some noise when slipping.
And yes, belt can start and stop slipping. Not much to loose, if you "run it into the ground".
The second problem seems independent. Now that you know how to reset it, again wait for it to fail. Replacing both, would be costly,
if you pay someone to do it. Have no idea what the parts are.
Both I consider DIY on a dishwasher. Take some patience, but can be done if you take pictures along the way, how things go back together.

A couple of things that you might try, Rich, before investing any money into the unit.
A whistle/whine/squeal often means a bearing is going out or you have something trapped in the pump putting pressure on the impeller.
First, I would get some penetrating oil, and spray in onto both of the motor bearings , if they are not factory sealed bearings, and usually they are not.
When the bearings are tightening up, it is difficult for the motor to turn and it may overheat, causing the thermal overload to pull the motor from the circuit. When it cools the overload breaker will reset. Hence that is most likely the reason your dishwasher started again the next morning.
If the bearings are getting dry, and you do not lubricate them they will soon seize and the motor will not turn at all. The bearings may also be corroding from a small water leak or drip.
If the above doesn't help, remove the wash arm, sump cover and pump cover. Check for foreign objects pressing against the impeller, or even more likely the hard food waste disposer blade, which is mounted at the very end of the motor shaft.
KitchenAid is made by Whirlpool, and they have a metal blade the grinds food wastes up, and it is located under a little metal grating plate. A foreign object may be pressing against this. I have also had the blade to bend and press against the grating plate, with the rubbing making a loud squeal. If it is rubbing very hard it may be putting a drag on the motor and causing it to overheat.
Most likely the first scenario is true as the Whirlpool made units often develop small leaks that drip onto the motor, drying out and corroding the bearings. Look for dampness on the motor. If there is a water leak, this will have to be addressed before re-lubricating your bearings.

Yes, that is correct Rich there is not belt in this machine nor is there a transmission. the motor drives the pump and disposer blade directly.
Have some fun and try the DIY method!
