wt7600hwa top load lg washer

[Ameyer]

hello hope someone can help me find my problem. lg top loader wt7600hwa washer is stuck at the 1 minute mark and then will finally shut done with an  OE code. checked and found no obstructions. then replaced the drain pump. washer still does the same thing. the clothes have spun all the extra water and are ready to dry when this happens. also change the clutch out a few weeks back because of the lg problem that they wear and get the grinding noise. it seems that the problem of not stopping started after the clutch change. i am not an appliance repair man but have been over the years able to fix most problems that come up but so far this one has got me stumped. i was in the electrical trade for over 40 years so have some background on troubleshooting.  is there a senser or pressure switch possibly gives the signal that will give the oe code. the pump is dispelling all water and the clothes are ready for the dryer, when i replaced the clutch is there something there i missed as in a wire harness at the stater that could be loose and causing this? any help or thoughts i would appreciate to get this repaired.  possiblly the main board? troubleshooting  hints to figure this out?

thx
