Our 6 year old Frigidaire aka Electrolux (Model #: PLD4375RFC) dishwasher was leaking from the bottom of the door all over the place. I searched the forums, and I searched the net, and most of the posts recommend replacing the bottom door seal. The float does click when I pull up on it, and I don’t see any cracks or obvious holes in either of the upper or lower arms.
So I removed the door gasket, and it was a little worn at the edges, and corroded with deposits. I also removed the splash guards at the bottom of the door corners, and noticed they were split in half.
I’ve already replaced the bottom door seal gasket (OEM Part: 154576501) AND the side flaps splash shields / guards (OEM Part #: 154701001), however it’s STILL leaking. I think replacing the three gaskets helped a little, but now it’s leaking mostly at the center intermittently depending on what it’s doing.
So I ran it again, and took off the kick plate and looked under it. It appears to be leaking from the hole where the electrical connector goes up the middle of the door in between some white Styrofoam. I took some videos. See below.
You’ll notice it’s leaking a lot from that hole in the time-code 0:00–0:55, but right about 0:56 the machine changes it’s tune and goes through another cycle of some sort and it stops …

In this clip a little later on, it changes it’s tune again and goes through some other cycle or thing and the leak starts back up again at 0:12…

I have not replaced the tub gasket yet, but I don’t want to throw unnecessary time and money at this thing if someone can identify this for sure, and send me a link to the correct part? 
THANK YOU! <3
