Originally tried replacing the main control board (steady green LED) on my PDT825SSJ2SS and didn't solve. Main symptom was dishwasher kept turning on and off on it's own every few minutes until the DW finally died and became unresponsive. Built back in 2017 -- replaced UI top logic after pulling the door off along with door harness and all is well again.
One caveat for separating the two pieces of the door on the PDT825SSJ2SS model, there are 6 of 8 screws that you need to remove. Instead of pulling outwards as seen videos online, you need to push/slide the inside panel forward (away from you) first and then pull up as there are clips that hook into the outside door frame. If you pull outwards (or up) without sliding first, you will break the clips that attach the inside panel to the outside door frame.
