Used a lot of previous posts to get this far, appreciate all the guidance.

No lights, beeps, numbers on the user control panel.

Checked 120v, all good.

Main control board LED flashing approximately 1x / 2-3 seconds, is this indicating the UI board needs to be replaced?

Thank you

Yes, the machine control board(underneath the dishwasher) is flashing normal. So that usually indicates a bad UI Board.

If you want to verify that, You will need a multimeter to check for 13.5 Volts DC 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 Volts DC is found here, then the UI Board is the problem.

Here's the UI(user interface) Board for your model: WD21X31902

"NOTE--->When replacing UI control boards, the new UI Board MUST be configured as per the instructions included with the replacement. If the personality is not set by using the 4 jumpers, the buttons, LED’s or cycles will not function properly".

Connector J722 is located on the metal casing side of the main control board.

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

Let us know how it goes.

This video gives you the general idea of how to replace it:

Thanks @Jake

Got a reading of 14 so I will get that UI board ordered and hope that squares things away!

Ok good, yes 14 volts DC is fine, the new UI Board should fix it.

Let us know.
