How to Troubleshoot & Replace Bosch AP4339629 / 00645141 Door Seal

I examined the situation and realized that the two plastic pieces at the back of the upper spray arm had simply oxidized overtime and weren’t sliding past each other as well as they did when they were new. I looked up the replacement part on appliancepartspros.com and easily found it. I decided to replace the main tub gasket as well. It’s quieter than it used to be and it works like new. Thanks, appliance parts pros! This is the second time you guys have saved my bacon! 

The 2 seals on a dish washer door are the Door Seal which attaches to the body of the dishwasher and the lower door seal which connects the bottom of the body to the door. It was not clear which was leaking so I bought both parts, watched the videos, and got to work. The door seal took only a couple of minutes to replace as you just pull out the old and push in the new. The lower door seal requires you to pull out the dishwasher and take apart the door. Turns out this only takes unscrewing 12 screws. The old lower door seal had 3 inch tears on both sides. I just followed the video and it was all done in about 30 minutes. So far it is working great and I hope it lasts another 10 years. 

Bottom door seal/door seal. Watched the video’s-which are excellent step by step. Longer to pull out and clean grooves than installing seals. Being retired don't get in a big rush. Delivery was about a week. Replaced door lock from “competitors”- 3 weeks delivery ????? figured was Post Office. Appliance Pro is by far the best. Have a quick link to the site now. Thanks
