I have a leak in the door of this unit and I have already replaced the door seals and the door gasket is tight. Is there an other seal I am missing?
Here are your parts

By seals I assume you mean Item 49 in Section 2.
Did you also replace the splash shield kit AP4338941 as suggested in the parts info?
Check that the spray arm holes are clean. Sometimes you can get a partial plug which can spray out at a weird angle and cause a leak.
It may be just semantics but you said “in the door”, if it is actually in the door then perhaps it is leaking around the dispenser.
