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.

The replacement lower door seal fixed my issue. It was a fairly easy part swap and the order arrived quickly from AppliancePartsPros.com.

I removed the screws on the dishwasher door using a T-15 torx screwdriver. I then separated the outer and inner door. I then removed the 5 3/16 screws holding the lower door gasket seal. I replaced the old gasket seal with a new one that I purchased from AppliancePartsPros.com. I then reattached the inner and outer doors. I made sure that the dishwasher unit was level afterwards.
