Ok… like you I read reviews before purchasing the LG All in One washer dryer. I did not heed the warnings.
After 3 weeks of use (just my husband and my laundry- light loads), the dryer timer stopped functioning correctly and never turned off.
While I wait on resolution, (because there is no LG repairman in my area) I can still use my machine, however, I must put on wash only, then manually set the dryer. The dryer is no longer drying efficiently.
Liquid soap dispenser doesn’t always dispense.
Cleaning this monster is quite a process. I cannot access one of the filters the directions say to clean because there are NO screws to remove that said filter/coils!!! 
I’m believing the dryer isn’t as efficient because I cannot access that area at all!
What a shame!
Purchased in late May. Still waiting for LG to resolve this. I just want a refund.
