Now this was not a real good plan the water needs to drain if you just purchased the home or had it built I would contact the seller or builder and have this repaired.
The vent can be fixed in above or below the Machine level.But it has to be in direct opening with out a U trap.Under the ground level is not good if there is block of air flow.
