kenmore dish stuck in open position

kenmore door stuck in open position. i have had this problem before and somehow i fixed it but cant remember how. i tried running thru the cylces seems its stuck in a locked position. model number 66516522000. I pushed the latch to open the door and it has stayed in that position. door wont close.

I’m afraid I did not get it clear…

You can not latch the door or it stuck in a middle position and you can not move it?

The model number you posted is incomplete. Verify and repost it.
