Leaking on LXIH dishwasher that is level

No. The water level is controlled by two probes inside the back RH corner of the tank. Level the unit with the smallest tilt backwards.

I would closely look at the wash (and rinse arms if equipped). Make sure there is no missing plugs (depends on how old unit is if plugs are used), and that there is no debris inside the wash arm. Debris will cause the water to spray off-line and hit the door seam directly.

Also look at the lower washarm to see if it has a split in the seam. This can spray water directly at the door.
