Frigidaire Dishwasher Leaking From Door

[SchlockRod]

There's a whole lot of people with FDB model #s that have leaks.
Can anyone tell me what's likely wrong with this FMB one? (service bulletins, etc. appreciated) FMB330RGS0
Leaking at bottom left corner. Is full of dishes top & bottom.
Bottom seal does not look like the one I've seen pix of on those other models. This is like a double flap of black rubber. It's bent a little flatter in one spot, but I don't know if that's enough to cause leak.
Bottom seal was caked up with crud as was sheet metal that it contacts. I cleaned both with scrubber sponge.
Still leaking.
Side/Top seal looks OK.
DW is level but there was about 1/2 inch of water in the bottom when I opened it during spray cycle as it was leaking heavily. Is that normal? I pulled the drain strainer out and water didn't go down. Now I've opened it during part of cycle w/o spray, and there is no water.
See pictures:
1. Side seal and bottom seal from inside. 2&3. Flattened part of bottom seal.
