I'm probably yapping here to procrastinate taking the dishwasher out and apart again..
My dish washer's control board (aka User Interface board) went kaput again. The first one died within the first year. I replaced it September 2020, and the replacement just died too. This board fits inside the dish washer door top, with a 3-digit 8-segment LED display, buttons to select cycle, and a beeper to tell you washing is done.
Horrible place for a PCB. The steam from the washing come inside the door via a circular vent on the interior side of the door, travels inside to door to exit outside via a slit-vent on the front side of the door. The venting path is an open path (no ducting) mere inches away from the PCB.
I found a replacement board on Amazon. This seller description (see attached screen photo) says this washer UI board is: Computer and laptop connectivity, USB interface , compatible with Windows, Mac OS, and Linux, with a fresh rate of 192KHz. I broke out laughing reading it -- None of these description is correct. This board merely connects to the inside machine control/power board, and dumb as a nail. The replacement merely has 4 jumpers to select the right model.
I am not sure if it was AI assisted description entry, or the seller has no understanding what they sell... Good employees are hard to find, I suppose.
