Frigidaire /Electrolux dishwasher touch panel stopped working - fixed!

[@byugrad1024]

I am an experienced electrical engineer who designs embedded electronics. I have this exact same failure condition where the start button does not register after some time. I can gently coax it into working again by repeatedly pressing combinations of buttons and opening and closing the door. A few times, I have had to run to the basement, flip the breaker and reboot the dishwasher. This seems to solve it every time. This leads me to believe the failure mode is not corrosion (I have never taken mine apart to have a look), because in every case I can get it to work again by a reboot. This seems to me to be more of an issue related to latchup within the microcontroller and the way it samples the button PCB. Astute users may also notice the LED's get faded, and sometimes the numeric display is difficult to read. This is further evidence of latchup where the logic 1's and 0's aren't getting written or read by the microcontroller properly. I hate that we are where we are today with junk products, but that is the current state of affairs and there appears to be no known fix for this issue besides removing power and thus removing parasitic charge that happens to be somewhere in the system.

This is the exact same problem that I have. I usually open and close the door several times to get the display to show and then press the start button repeatedly until it beeps and the close door prompt shows. Are you saying that replacing parts such as the control strips won’t fix this? I’ve been putting up with this for several years now. I’ve never tried just throwing the breaker.

I had an issue where all buttons worked except the start button. I saw from a previous video that the pins at the contact were dirty. I removed both ribbon connections and put them back on and now it's working great.

I’m having the exact problem now, will try that method. Thanks.

How did you get the cover off the user interface ? I”m having the same issue and I suspect the cause is the same as yours

[@Dj_Nizzo]

Can you link to the video that you saw that gave this info. I’ve searched, and can’t find it

May be this one: kzbin.info/www/bejne/mIW3aZ6CabJ4bMk

[@edwardtan8998]

thanks for posting this. Will give it a try

[@bluev3nom]

In that exact same spot, my top interface bubbled up and is hot to the touch. My screen won't turn on mine now. Taking it apart now to see why.

[@genegagne8117]

Video would be helpful if you actually showed what you did.

[@edwardtan8998]

btw, aside from the syptem you mentioned, mine sometimes display error code "PF" or "CL" Does this ever happen to you as well? thanks

[@lovethosebudgies66]

Closeup of part please. How to replace it. How to get to the innards. All I got from this is the name "circuit riding pin."

Is it a Frigidaire Gallery dishwasher Fghd2465nf1a

Thanks! Here’s (possibly) the video referenced: kzbin.info/www/bejne/mIW3aZ6CabJ4bMk

As others have said, what on Earth is helpful about this video? You don't show how you separated the UI assembly from the buttons, you don't show what you used to fix it, you can't remember the name or provide a link to the video you describe. You clearly wanted to help others with the problem - which is a nice intention - but you took no effort to do anything, talk about anything, or consider what it is people would need to know to be helpful. Not even sure why you bothered posting the video as such.

Not helpful. Demonstrate
