FIXED GDT655SMJ5ES GE dishwasher rapid flashing green light

I have a GE GDT655SMJ5ES dishwasher with power to the main board and rapid flashing green light. I have no lights on the controls on top of the door. I have the square main control board. I do not have low voltage from pins 2&5. Do I have a main board or UI board issue? Thank you
Ok, then the problem is the UI Board. Another person had this same issue and the new UI Board fixed it:

Here's the UI(user interface) Board for your model you can order(Video Included in part link): WD21X31902

Here's the manual instructions to replace the UI Board below. Disconnect power to the dishwasher before you begin.

You will need to remove the whole door, then separate the door, then remove the front control console, to replace the UI Board.

Here's the service manual for your model: https://drive.google.com/open?id=1M-G9W3HiaYnihdB5Cy-jfSPoVf8DZ7j7

Page 30 Separate Door
Page 31 Front Control Console Removal
Page 32 UI Removal

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.

Let us know how it goes.
I replaced main board and still nothing except rapid flashing green light. What am I missing. Thanks
For what it’s worth, thinking if I have power into a board and no power out replace the board. Took the (new) main board back and exchanged for another and installed. Everything working properly at this time.

Thanks for the reply. I was convinced since I had no low voltage coming out of new board it must have been bad also. Exchanged new board with another and installed. Everything working properly at this time. Thanks for replying
I understand completely, no worries.:)

Glad to here the exchanged new machine control board fixed it.(y)

Here it is for your model, in case others need it too: WD21X32163

Thanks for the update!
I have all the same problems on my 5 year old GDT695SSJ5SS. This week I’ve replaced both the main control board & UI..I’m still getting the rapidly flashing LED on the control board & UI panel is still dead. Any suggestions?
