How to Troubleshoot & Replace Ge AP3794323 / WD12X10109 Fine Filter

Partway through a normal cycle I heard a crunching/grinding noise as the dishwasher was trying to exhaust water at the end of a wash phase. The dishwasher continued to the end of the cycle but when it finished there was still a lot of water in the bottom. I suspected the drain pump had failed. I took off the front kick plate and found the drain pump. It was humming so it had power (thus the circuit board was OK) but there was no sound of moving water. Referring to the AppliancePartsPros.com video. I removed the lower wash arm, the fine screen, and the coarse screen. There was a huge amount of solidified greasy gunk in the sump under the coarse screen. I suspected a piece of the gunk had broken off and broken the drain pump impeller. The pump is a sealed unit, so I ordered a new one. It arrived in a couple of days. Meanwhile, I cleaned out all the gunk in the sump. The hardest part of the repair was disconnecting the dishwasher and removing it from under the counter. Once the dishwasher was out and tipped on its side, the AppliancePartsPros.com video explains clearly how to replace the pump. Very easy, just a couple of screws and a couple of hose clamps. Reinstalling the dishwasher under the counter was fussy but not difficult. It now runs perfectly! Just saved myself several hundred dollars. High marks for the AppliancePartsPros.com video!! These guys deserve your business. 

Replaced several parts of which all fit like original and it was a fairly straightforward repair. Only difference from repair video was a support bracket and 2 screws that I had to remove. 

After seeing videos on the website and how easy the repair would be. I ordered the fine filter and the lower, middle and upper wash arms. The repair took about 45 minutes to replace all of the parts. You will need to clean under the lower arm. The fine filter will probably have a lot of debris and gunk trapped. 

Fine filter replacement. (never knew it existed after 12 years of use) 

I ordered parts, replaced them. The dishwasher draining and cleaning back to standard my wife can accept. 

Went great. Watched video all good. Took 10 minutes. 

Super easy to change, I did it myself within 5 minutes. 

Took the filter off and tried to clean it. But some of the stuff would no come out 

I ordered a new Fine Filter and Nut Hub and then watched the AppliancePartsPros.com video on how to remove the old parts and install the new parts. Once the old parts were removed, I cleaned several of the remaining surfaces. The only tool I used was a flashlight for extra lighting. These parts were very affordable and the repair video was great. I saved many $$$ by doing this repair myself and not calling a repair person. THANK YOU SO MUCH. Rich, Roseville, CA 

To identify the problem, I put a small coating of Vaseline on the seal face to see if the problem stopped. It did. Since the seal is not sold separately, I had to purchase the complete dispenser unit. The Pro's video on how to replace it was perfect. Simple 30-minute job but don't remove the two screws that hold the latch in place, located at the middle top of the door. They are a different screw from those needed to be removed to remove the door face and gain access to the mounting screws for the dispenser. Also, be careful with/riibbon cables that connect the touch panel to the motherboard. Removing them to set the door face aside makes the job easier....but be careful of them.
