Product review (5 stars): Most of these leak internally right out of the box, here is the fix.
To anyone who still owns one of these, I have recently found the fix for those of you who are dealing with dirty dishes even on the most aggressive settings.

LG uses a thin foam gasket to seal the bottom of the turbine housing. The foam is just a bad idea because it doesn't hold up to the water temperature, and it would appear they didn't make it thick enough to properly seal the turbine housing, so most of these dishwashers leaked right out of the box. LG should have known better and put an O ring in place of it.

If you like to do it yourself and are wondering what the fix is, this is most likely it.

1: Remove bottom rack
2: Remove all stainless steel philips screws holding filter assembly together on the bottom of the dishwasher.
3: Lift assembly out of the housing and gently twist it to free it from the top rack water line (do make sure that screw holding said water line was removed).
4: Turbine will now be exposed, this is a good time to clean out the gook.
5: Stainless screw holding turbine in place is left hand thread and may be very tight, I have a small impact driver that made short work of this. Remove turbine.
6: The turbine housing should now be free, lift it up and take a look at the foam gasket or what remains of it towards the back of the dishwasher.
7: Carefully observe where the turbine housing needs to seal and test fit a few rubber o rings to make sure the fitment is good by placing the turbine housing back with new o ring in place and pushing down on the housing a little bit while looking to see if the o ring compresses a bit. I purchased the o ring kit at my local auto parts store in their "Help" section for about 5 dollars.
8: If everything checks out good then you are ready to put everything back together again.

It is also worth noting that the top seal of my turbine housing was squished pretty good, this is a proper molded rubber gasket that can be purchased at many appliance repair websites, LG part number 4036DD3001A. Additionally, several other seals in my filter assembly were looking pretty cooked. I opted to replace mine with an o ring maker kit, but you may want to order the correct ones while you are shopping for the top turbine housing gasket.

Thanks for reading and I hope this helps.
