I have a GE Adora - model DDT595SSJ4SS - that isn’t working. The main control board has a green blinking light that saw on another post for a different model suggests that this board is functioning properly. The UI panel has no lights and there is no response when pushing the buttons. Any help would be most appreciated.

The main control board has a green blinking light that saw on another post for a different model suggests that this board is functioning properly.

You have the old style machine control board, where it should flash a pattern, like 1x per 1 second or 1x per 3 seconds or 2x per 3 seconds. What is that pattern its flashing?

--->Here's the machine control board for your model: WD21X24901 Machine Control

It’s flashing 2x per second.

 

[Jake]

I don't a error code for 2x per 1 second just this--->2x per 3 seconds--->Dishwasher is in Delay Start and waiting to start a cycle. The cycle will begin once the delay expires.

You will need a multimeter to check for 13.5 Volts DC.

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: WD21X31910

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 what you find.

Thanks for the tips. I checked and the reading was ~2.4 volts. When I plugged the connector back in the light on the board started flashing again, but this time at about 1 x per 3 seconds AND the UI lit up. I was able to then start the wash cycle normally.

Excellent, glad to hear that, hopefully this problem will not re-occur, if it does come back and let us know, because 2.4 volts is way too low.

 

[Zachary]

I’m back. The UI has ceased working with no lights or indicators. I went back and checked the voltage coming from Connector J722 and that registers 14.03. I unplugged and replugged the connection a couple times since that worked to reset the UI last time but to no avail. The green light on the control board is solid green. Any inout you may have would be most helpful. Thank you!

Ok, 14.03 volts DC is good. So the problem is the UI Board.

Here's the UI(user interface) Board for your model you can order: WD21X31910

There is a video in that part link.

Let us know how it goes.

 

[Zachary]

Thank you. Part is in order!

 

[Jake]

Sounds good Zachary, let us know how it goes.

 

[Zachary]

It worked! Thank you for the help!

Excellent Zachary, glad to hear the new UI(user interface) Board fixed it.

Thanks for the update!
