Kitchen Aid dishwasher door falls open

I have a Kitchen Aid Dishwasher that has a door that no longer supports itself and it falls open if one does not support it when opening. Do I need the link kit AP3775412 or something else perhaps?

Thanks,

Tim

In case anyone is having a similar problem, it turns out the fix I needed included this:

AP3777680 (8535568) - Link

Hope it helps…
