ZBD3900C00SS General Electric Dishwasher - Instructions

Removed filter screen with the socket set, removed the piston and nut assembly with pliers, and installed the new piston and nut assembly. Put filter screen back in with hex head screws. During the process, I opened the float regulator and cleaned it out too. Water backup problems solved.

Ordered door seal and followed directions included with the seal. I did put the seal in the clothes dryer for 5 minutes prior to installation as recommended in the Parts Select video that is posted on You tube.

Unscrewed bottom of spray arm support assembly counterclockwise by hand for removal. Inserted new part and screwed it in clockwise by hand for installation. Worked perfectly. Video was helpful.

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.

The repair could not have been more easy! We simply unscrewed the broken spray arm and screwed in the new one. For less than $50, we fixed it ourselves. We would have paid in excess of $350 for the repairman to fix it. We could not be more happy with this website, the videos and the fast delivery!

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.

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.

Very simple to change it, only follow the instructions that came with the part and don’t have how to do wrong

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.

Not really difficult to do. First remove the washer from the counter and flip it over. Carefully determine the correct drawing in the instructions which matches your machine. Follow insructions and double check everything. Took about an hour - and I saved about $350.00 by fixing it myself rather than buying a new one!

Just remove the 4 screws at the lower rear inside the washer to remove screen holder...then unscrew the Piston and Nut Assembly by hand. Put in the new unit, reattach the screen holder with the 4 screws...and the job is done. Probably takes less than 5 minutes....very easy.

Basically, I told my girlfriend, hey, if you are board, this box has the parts to fix the dishwasher in it. When I got home from work, I had to connect one wire, and tighten a couple of screws. The kit has great, easy to follow directions. Thanks!!

Installed new motor and pump kit. Very easy, except that the instructions did not give any detail on the electrical hook-up. The problem was that the electrical connections for the motor and solenoid were the same on the replacement kit, making it possible to switch them. Be sure and mark the connections from the old unit before removing them.

I had a problem where the GE dishwasher would randomly stall upon startup due to a dead spot in the motor which prevented it from energizing. I removed the dishwasher's bottom access panel to inspect it and found that not only was the motor dead but it had a sizable leak emanating from the pump seal. I removed the dishwasher from under the cabinet area and turned it over to make it easier to replace the motor and pump assembly which only took a matter of minutes; the most difficult part of the repair being the reinstalling of the dishwasher. The replacement motor/pump assy was not only modified from the original parts but it is also much quieter than the original. I also have to commend PartSelect on their very speedy delivery which was only 2 days. All in all with a couple of minor modifications that was taken care of with the included parts the repair went very easy.

I went to your site and check all the diagrams and then read the postings from others. I turned off the electrical breaker then took off the lower cover of the dishwasher. After disconnecting the water and electricial connections I was able to remove the 2 screws holding the unit in place and it came right out. I turned the unit over and was able to just remove the old part and put the new part in place. The whole job took me about one hour but I had never worked on a dishwasher before. Your site made the repair very easy to do on my own.
