Whirlpool W10909089 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.

The part from AppliancePartPros.com was perfect and I followed the associated video. While there are some differences in each dishwasher, the video guided me step by step to replace the lower door seal. I used a nut driver that was not magnetic; however, a magnetic nut driver would have made the job a lot easier.

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...
