Diagnose Codes and Replace Repair Bad PCB Control Board in GE Dishwasher

I have a GE dishwasher that had a bad PCB printed circuit board (motherboard/control board) and I ran tests, ordered and replaced the board. This video does not cover disassembly because you can find that elsewhere for your make/model. But I do show how to navigate consumer error mode, service mode, and the service LED on the main control board to get clues on which board could be failing / bad and you need to replace.

This is the most useful video regarding how to fix a malfunctioning dishwasher. This is the first step that one needs to undertake, before dismantling anything...

Thanks for sharing this video. Very helpful. I have a different GE model GDF620HSJ6SS and have a similar sheet of error codes and things to check. In my case, all of the control panel lights suddenly went off and no combination of pushing buttons simultaneously has any effect on the dishwasher, it’s like it’s dead :( so I called for service. The technician checked the washer and concluded that either the main control board or User Interface (UI) board is bad and advised me to just get a new dishwasher because the replacement boards work for a few weeks and quit ! Now after watching this video, I’m motivated to check the main control board and see if there’s any sign of life, I don’t believe in simply discarding a 3 year old $700 appliance without a bit of a fight!

My dishwasher has a problem where the top panel lights and controls stopped working. The main board has 120 volts power going in and it has a steady green light. It also has the 13.5 volts DC current going out to the top control board . I am still trying to get an answer on the correct part needed but I think it might be the top board.

Did you get your GE dishwasher going? We have same problem! UHG

This gave me the information I needed. Thank you! Portable GE dishwasher

Great camera work, very informative video. Thank you!!!

[@geraldwe]

Great video! Thanks! My service light on the lower board won't come on at all, so I'm going to replace the lower board. My upper panel seems to work fine.

[@Mejia93635]

Did it work?

[@geraldwe]

@@Mejia93635 Yes, it worked! I replaced the lower circuit board, and the dishwasher works fine now.

[@Mejia93635]

Thank you for the information 👍

[@Airdaddy55]

90% chance your both boards are bad. GE makes junk. You'll be money ahead throwing that piece of shit away.

[@schattenmygirl]

The "Monkey See Monkey Do" parts of your video really was helpful Thanks

[@Zlife-kz1go]

Great video. Very helpful. I have all my lights on except start and when i push start it just beeps but doesn't start cycle.?

[@dickmoser3472]

I have same issue and don't know what to do.

[@dickmoser3472]

Thank you for sharing! Very helpful. For some reason when I am ready to wash and push the start button after a few seconds I get a beep and the light on the front blinks and no start. I don't know what the blinking light on front door means. Do you? Thanks!

[@6sensory]

Very Helpful. Thanks

[@GUSTAVO-uy6ps]

what if my light is flashing fast many times.

[@djleonardove]

Thank you for your help. Thumbs up

How can I get a replacement sheet like that?

[@amyhayes1647]

could someone possibly send a link or a screen shot of the service diagnostic sheet ? I have the manual but the diagnostic sheet in nowhere to be found.

[@morgandodsoncoaching]

I found this one but it wasn’t my exact model but it was close enough, it might work www.applianceaid.com/pdf/31_9253.pdf

[@dontadlock2028]

At 4:35 in the video you are pointing to the BOOST light and stated if the lite is lite you would be having an error with ??? Sorry I was unable to hear your comment. Please type answer here

[@tammygirlm]

My dishwasher is afloat if not exact to yours.... But my lights do not come on at all, nor my dishwasher run at all... It has power to it, even to the door, but control panel I guess is out, you think?

[@defomatt2684]

What if you get no lights up on top at all, I did confirm I am getting 115v up to the top of the door.

[@danaraemiller349]

I have the GE GDT680 model. My heating element is not working. I replaced the element, but that was not it. The user interface board they sent me has a "personality jumper" that has to be configured. I ran the test you showed by holding down the cycle and start. They all blinked and the only ones left on were the "autosense" and "lock controls". What does that mean? Also, do you know how to set the jumper on the new board? It's Christmas eve and I could sure use the dishwasher... ;)

[@HimsinBoston]

My bottom circuit board solid green, bottom of machine controller board. But my buttons don’t ON. No power to up buttons, which board is dead? Top one buttons or controller?

[@dougarnold2121]

I have the exact same dishwasher. How many times did the light flash for the board you replaced?

[@brianorlando6423]

So if the LED on the main control board is dead or not flashing or lit up then I need to replace the lower main control board? I can't find much information on this. Thank you in advance

[@chevyguy2536]

On mine the door controls are dead ,nothing. the main control board led is flashing so fast the light just dims a little, any help please

[@RIZZO037]

How do i find Service Diagnostic Sheet. nothing that i can find under machine. Please help?

[@judylepthien9891]

I see several people have the same problem I have and that is getting the service diagnostic sheet. Where did you get those. I called GE, emailed them etc and they say they don't have them, so I am wondering how you got them? Please reply.

[@PH-md8xp]

Hey Judy, I found my service diagnostic sheet tucked into the left foot of the dishwasher, it was visible after removing the kick plate. Apparently the manufacturer places it there.

[@rfworld60]

When you had all lights flashing if you closed the door switch would they stop flashing. or if you held the door switch in closed with a screw driver would the lights all flash in the test mode?

[@propayne426]

I would also like to know this.

[@porterfamily789]

I thought my code was Fed but it might be Ftd (failure to drain)

[@carlosjackson4474]

I have the exact same dishwasher, but i did not get the service diagnostic sheet, where can i get one from?

[@nobodycares2354]

Mine was underneath the dishwasher

[@sl5311]

Where did you get this sheet?

[@earthn1447]

It is under the front behind the panel (kick panel) under the door- take out the two little screws, then look on the left side - folded into a 2” square tucked on the side by the foot

[@sl5311]

@@earthn1447 Thanks, I think mine was taken.

[@hotrolls3473]

The service LED light on my GE model GDT695SGJBB is solid green wether the door is open or closed so I bought and replaced the UI board (WD21X23463). It did not fix the issue. The issue being, no lights or functionality of the UI touchpad. Dishwasher is not working at all. Can you help?

[@nobodycares2354]

So if that didn't work, guessing it was the bottom one that needed replaced. Did you ever figure it out?

[@hotrolls3473]

@@nobodycares2354 it turns out that it was the top interface board. It needed to be programmed. I ended up having to call a technician to program the board I had installed.

[@spookville6632]

@@hotrolls3473 Yes I believe there are a few jumpers in a row that need to be placed in the right position (jumpered or not jumpered) although according to what you wrote it sounded as though the bottom control was defective> depending on the model the green led lite should be a steady flash or a double time flash (where the control PCB is square shaped)

[@hotrolls3473]

@@spookville6632 The board manufacturer did not install the jumpers during manufacturing. In addition, my board needed a software update so I had to call a technician who plugged into my board and installed the update.
