How to Troubleshoot & Replace Ge AP3994749 / WD01X10342 Coupler

Replaced sump and related pieces. Also replaced door baffles that were getting bad. The hardest part of job was removing the dishwasher from the its spot in cabinets. The info on site made replacing parts easy. 

Replaced the part, a coupler.. 

Ordered new parts and put them in! 

The water was coming out of the overflow into my cabinet not just into the drain. Turns out there was just debris in the drain little draino cleaned it out I took that opportunity to change the discharge hose and clean all the filters. I had the special order the little rubber coupler that had disintegrated and the large filter as it was so gross it wouldn't come clean. It was an easy repair just a little tough getting underneath the washer to change the hose. 

After viewing a few videos on how to remove the spray arm and filter below it, removing and replacing the rotted coupler (part 450, attaching the filter to the spray arm base) was easy. Removing the spray arm required reaching around with a screwdriver to pop a lever on the back side of the spray arm to remove it, then unscrewing the filter and moving the lever the other way to wiggle it out. Then I popped off the rotten coupler, slid on the new one, and replaced the filter and spray arm. I replaced the silverware basket, too, since the one on our 7 year old washer was cracked. 

On google search engine found the help to fix the issue along with the parts. With the help of videos and parts, I fixed it right and got it working. The help made it very easy to fix, but I took enough time to make it right and avoid any possible leaks. 

Mostly just cleaning. I also discovered the Coupler (small tube) was cracked and the Fine Filter hard to get really cleaned out. The videos at Appliance PartsPros.com make taking things apart to clean and repair a straightforward task. 

I watched the repair videos provided by Appliance Parts Pros and I was prepared to change parts. I removed the dishwasher and took out all the old parts and easily replaced all the ordered parts with the new ones with no trouble. reassembled the unit and ran a cycle and the dishwasher was operating better than I have ever remembered. %Thank you Appliance Parts Pros for your detailed and instructive videos. 

Had to order a new water coupler and re-install, took about 5 mins. 

At first I thought the coupler was a chunk of debris, it had partially disintegrated. I pulled it out and went online to find a replacement. This was very easy with AppliancePartsPros. While replacing the coupler, I cleaned some parts but the fine filter could not be cleaned to my standards, so I ordered a replacement from AppliancePartsPros. The job was easy and the video was very helpful in finding those tabs that need to be pried the right way, so they don't break. (btw: I'm a 77 year old female).
