Ok Austin, Let's check voltage to the UI Board.

The UI operational voltage is output from the main control board on connector J722 pin 2 black/green to pin 5 yellow/blue. If 13.5 VDC is found here, then the UI Board is the problem.

Here's the user interface(UI) board for your model:

That J722 connector is on the other side of the control board, look here:

It's the one on the left above the ethernet port.:)

Let us know what you find.

Ok, so your machine control board STATUS LED is STEADY ON too?

If so, do what I mentioned above to Austin in post #2.

Your model uses the exact same UI Board I posted in post #2 as well.

Yes Mark, exact same procedure on yours too.

Only difference is your UI Board is a different part number.

Here's the UI Board for your model: WD21X23462 Kit Svc Ui Top Logic

Let us know what you find.
