whirlpool dishwasher quiet partnet III door leak

Whirlpool QuietPartner III GU3200XTSB2.

Leaking at bottom of door. Water drips on the floor to the left and right of the leveler legs (part 8524584). Removed front door panel (part 8269841) and run dishwasher to have better point of view from where its leaking.

Two places water leaks from:

No.1-Water travels out by the inlet air (part 8268937) which is fixed at the bottom of the inner door (part W10084289), and travels left and right along a lip of the said inlet air, and drips on the floor to the left and right of the leveler legs.

It looks similar to this:

(note: the little cover Eric Nay is referring to in the comment section of the youtube link is fine on my dishwasher; and anyway I don’t see how this could be the source of the problem as it would spray water in the middle of the inner door)

No.2-As well, water comes out by the door latch hole at the top of the said inner door, travels down the outer surface of the inner door and then follow the same path left and right along the lip of the said inlet air, and drips on the floor to the left and right of the leveler legs.

A new door seal will probably overcome water leakage source No.2, but I’m wondering what is causing water leakage source No.1 ?

Other brands aside from Whirlpool and Kitchen Aid have a rubber seal at the bottom of the inner door, instead of an air inlet.

Thanks in advance for advice!
