GSD3900L20CC General Electric Dishwasher - Instructions

from the information previous customers had written.
it saved a lot of fustration and time
and best of all the dish washer does not leak.

I connected one end of hose to the drain using a hose clamp and screwdriver then connected the other end to the dishwasher using anouther hose clamp and a screwdriver..

At first I thought I would call a repair man.Then I thought-that will be at least $100!So we went online and found the part.Took about four days to arrive.I pulled the dishwasher out and turned it on it's front.The little leaking hose was easy to remove,two clamps,and the new one installed.Total cost-$14.00.

Open door, remove lower wash rack, remove 4 screws holding screen in rear of inside tub with 1/4 inch socket. Unscrew piston and nut assy for checkvalve, sounds like a mouthful but it is only 1 part. Checkvalve has 2 small ears on it which allow you to twist it out, it has treads on it. Flapper on check valve flapper rots away and water pumps back into tub instead of being routed to drain line to garbage disposal. Part with shipping was just over $20.

Ordered motor and pump and replaced. Motor pump kit also comes with a drain solinoid so if that was the problem the kit repaired it. One issue is the size of the hanger to ensure the pump does not just hang on its mount. The directions were not very clear and after some trial and error I got it to work to.

Removed the 4 screws on front inspection plate and had easy access to solenoid switch. Unplugged unit and switched out with repair kit. So easy a caveman could do it...

I removed 2 screws a wire plug connector and replaced the old part. The total repair including putting the cover plate back on only took about 15 minutes. Also I saved approximately $130.00 by doing this repair my self.

First I opened the dishwasher and removed the lower basket. Next I removed the 4 screws that hold the food filter plate in place at the back of the tub. Then I unscrewed the Piston/Check Valve assembly counterclockwise, located at the back center of the tub, by hand. I replaced the old part with the new one and reinstalled the filter plate. I ran a rinse cycle to verify that that all of the water was purged. Finally, I reinstalled the lower basket and resumed using my dishwasher.

First let me say, it's so easy even a caveman can do it. I removed the water out of the bottom. Then I removed the cover in the very back of the machine with a wrench. As soon as I did that, I could see the piston. Next, I twisted the white piston out with my fingers (this was the hardest part). I could see the piston had partially disintigrated. I ordered a new one, had it delivered in a few days, and put it all back in reverse. It took minutes. Thanks to the guy that posted his story, I was able to fix mine for $18.

I removed the end caps on the two side tracks using pliers. I pulled out the old rack and inserted the new one. I replaced the end caps and I was done. It was that simple.

removed screen at back of dishwasher from the inside. Twisted piston & nut assembly out by hand and replaced with new one. Very, very simple. Dishwasher works perfectly now.

after I let the unit rest on its side to expose the bottom part, I took a picture just in case for reference; I marked all electrical connections, so it would go to right place into the new unit; removed the old pump unit by loosening the rubber clamps, for the inlet and outlet; detached the support sling for the motor unit; installed the new pump unit; it fits like a charm and it was wonderful; I had some bad experiences of replacement parts from other suppliers, on many things that I fix , that won't really fit like the original, but this one fits like a charm; I made my first test run with just water with out the detergent and after one cycle I used the necessary dishwasher detergent and it works just like brand new; Thank you, PartSelect, I will be ordering any of my part needs from you. - G.V.

This was one of those wonderful repairs where anything went right.
The part arrived overnight as ordered and even though I was abit leary of it fitting, since it was described as a replacement/new design, it fit perfectly! As mentioned in another post here, draining the water out of the unit so I could tip it over to do the replacement was the hardest part!
I'm sure I saved over $100 doing it myself. Thanks PartSelect!

Followed the simple instructions to unscrew the old unit and replace with the new one. The unit was easily located on a diagram on the internet and the website instructions for removal were spot on.

Used Phillips screwdriver to undo brackets that keep dishwasher in place. Pulled out dishwasher from underneath the counter. Placed hinge arm in spring, hooked spring onto clip, placed hinge arm in clip. Put back dishwasher under the counter and screwed in place. Took all of 15 minutes. Saved 185.00 for service call.
