Kenmore Front Loader LG built 796.40272900 weird problem

[Wedgeman55]

Hi guys, wonder if any of you Big blue techs have run across this.    On this machine,  it will run through a cycle.    After sitting,  and they go to start another load,   no response from user interface.    Power button,  everything dead.     But,  if you unplug it for 10 seconds, plug it back in,  it is fine.    Keeps doing this.    It's in a rental and she doesn't want them to have to unplug and re-plug it back in every time.    Now - I think the only thing it can be is the control,  but I figure I would ask some of the experts here if they have ever seen this before.   No error codes or anything show up.   Thanks

It's the control board. The main one at the rear left side. There was a service bulletin released on that very issue, and a change was made to the board to correct it.

If replacing the control board doesn't resolve the issue, replace the harness between the main board and the display board.  #6850ER2002W.

I had a problem exactly like this and replaced the display board, main board and power filter but nothing worked till we started changing the wire harness.  Then everything went back to normal.
