Whirlpool W10909089 Dishwasher Lower Door Seal OEM Part

My Whirlpool dishwasher was leaking out the bottom of the door. I replaced the gasket and the lower door seal. When I ran a test wash, it was still leaking. After reading more online, I found that it could be a cracked washer arm. The initial inspection of the washer arm looked normal but when I used my faucet to slowly pour water into the inlet of the arm, I noted that water was leaking through a seam and not just the holes where it should come out. I then tried running a wash without the lower washer arm in place and I had no leaks. I ended up ordering a new arm. Once that was installed there have been no leaks. My advice if you are having the same problem is to try removing the washer arm and start a cycle before you assume it is the seals. (my seals did not appear to be damaged but I assumed they were the problem) It might save you a bit of time.

Bottom door seal.

Ordered the bottom door seal and it came with the exact video instruction of how to replace it, which was AMAZINGLY helpful. Once it was installed, the leak was fixed. Also the part arrived in like 2 days, very fast.

I noticed water leaking under the door of the dishwasher and found that the insulation under the door was saturated with water. Some googling led me to check out the lower door seal as well as the spray arms. The spray arms didn't seem to be cracked but the lower door seal was awfully wavy. It took some effort to get the door apart and remove the old seal. There was a ton of gunk behind the seal, which made me pretty sure it was the cause. My advice if you think you need to replace the seal: take your time disassembling the door so that you don't pull any of the wires between the door panels and clean well after removing the old door seal. It was not a difficult job and seems to have fixed the problem.

So, I replaced the inside seal gasket and bottom lower door seal thinking that was causing the middle of the door panel to leak/dip. I spent $100 on two parts only to find out that they are not the parts that will fix this problem. I am awaiting repairman tomorrow to figure it out. $80 now for service call. The parts I ordered were brand new and what my dishwasher takes but I'm no repairman and should have just called the pros from the start. Lesson learned...
