LG wm1814cw UE error won't finish cycle?

LG wm1814cw UE error won't finish cycle. Have tried with full load, empty, short cycle, regular cycle, cleaned front drain filter. Motor seems to be working fine until it gets to about 7 minutes remaining...just about when the quick spin should begin. That's when it stops and shows the UE error. Since it is an unbalanced error we shifted items around, removed items, added items...nothing.

Any help appreciated...Thanks.
