How to Troubleshoot & Replace Ge AP3794288 / WD01X10242 Ring Nut With Gasket

I replaced the spray arm. It took a few tries before I got it on enough to click into place. So it fell off twice. I removed the top shelf and used one of those rubber jar openers to give myself a better grip. I was concerned that using a wrench might crack the plastic. I slowly applied more pressure until I heard a click. I haven't had a chance to run the machine again but hopefully it's on all the way this time.

The main conduit needed to be replaced because the threaded end had cracked due to over-tightening of the ring nut. This was causing a leak at the back of the dishwasher when running. Removed the old conduit and installed the new one, along with a new O ring and new ring nut. The Guide casing was not needed. To remove the old conduit at the bottom (near the pump) a hose clamp needed to be removed. The hose clamps used on my dishwasher were not designed to be re-used so this needed to be replaced as well. A quick trip to the hardware store was necessary. The whole job took under an hour. Only tools needed were pliers to remove and replace the hose clamp and a philips head screwdriver to remove bottom back panel to access where the main conduit connected to its feeder hose. 

I pulled the dishwasher out from under the counter and found that it was leaking in the back where the main conduit , ring nut, and top basket spray bar all intersected. I ordered the parts I needed form Appliance Parts Pros. The parts were delivered quickly, and the repair itself only took about 15 minutes. 

Took apart to see what the issue was, then replaced the needed parts. 

Replaced it with a new one.
