Samsung WF457ARGSGR touchscreen unresponsive

Hi all. I come here humbly and in absolute desperation.

I have this fancy schmanzy washer That, of course, is out of warranty. It is a 'smart' washer which equips it with an 8 inch lcd touchscreen. However, our screen is unresponsive to the touch. It responds to power and alters adjusts when the internal light goes on. Fortunately it is stuck on a cycle setting so we can still start and complete a load but under very basic circumstances.

I have so far replaced the touchscreen interface, the main control board/brain and the on/off button interface. All to no avail. It boggles me that it is still stuck on this setting after the entire brain has been replaced.

Last port of call is replacing the wires and entire harness. I've ordered the part but am hoping I can find a solution with you folks.

Any thoughts or insights? When I go into the diagnostic screen it shows a "code '02' - lcd: 0e86. Option 0014." - none of these codes are yielding any result in my searches.

I'm grateful in advance for any help or consideration that comes my way.

Thanks.
