Had a power outage for ~1 minute today. Not sure if the generator cycled on to supply emergency power before the utility power restored.
When the utility power was restored, the dishwasher now has a steady tone and no lights on control panel.

Powered the breaker off (for over an hour). No change. Multiple attempts.

Ok, sounds like either the keypad or control module has failed, or a loose connection. I don't have the tech. data sheet or service manual for this model, but all dishwashers come with the tech data sheet, it should be located either behind the bottom access panel or inside the control panel assembly. It will tell you how to test to see which part you need.

Here's the control module for your model, if needed:

Here's the keypad for your model, if needed: Keypad WD34X11512

FIXED:
The Keypad harness (719 on GE Schematic) Part No WD34X11512 had become partially disconnected from the Control Module (905 on GE Schematic) Part No WD21X10365.
I reconnected it and gained lighted but still had tone. I disconnected the harness for the power to the control module (as I was doing it hot). When I reconnected it the tone was gone. Running a cycle as I type.

Ok, good find Dan.

Did it complete the entire cycle?

So your back in business?

The cycle that I started did complete.
Back in business.
Thanks.
[On a side note, I am so not thrilled with these Monogram appliances. They are "gourmet" but not really anything better than a standard appliance with some lipstick IMO. I've had multiple service issues with 4 out of 6. But the warming drawer and the hood are good!]

Yes, I agree!
