GSC3430F00WW General Electric Dishwasher - Instructions

Removed filter/screen by unscrewing 2 screws with a nut driver and then unscrewed the old Piston and Nut assembly and simply screwed in the new part. Problem solved and my dishes are much cleaner and the water is draining out completely. Easy fix for this frustrating problem.

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.

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.

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.

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.

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.

I disconnected the power shut off water supply. I then removed the drain hoses and water supply to the old pump. I removed the ground wire and the mounting rod to the old pump. Once removed, I followed the easy illustrated diagrams and instructions that came with the replacement pump.
I mounted the new pump using the supplied hardware and reconnected suply line and drain hose. I turned water supply and power back on. Ran a test cycle before reinserting under countertop. Amazingly quiet and no leaks. Repair a success.

I would use this service again if needed for additonal home appliances.

Thank you

The replacement of the motor and pump assembly went smoothly and without difficulty however this did not fix the problem. It then appeared that the inlet water valve was not operating properly, so this part was ordered and instlled, a very simple proceedure that could be done witrhout removving fthe dishwasher from its cabinet. -- Again failure to run -- the timer assembly and electronic panel were then removed and examined. The control panel had no visible defects, so the timer assemblyand its cover was removed and examined . Uing a variable power supply the drive motor for the timer was energized and tested. As the motor ran properly the electrical switching contacts were then carfully checked, it was discovered that one contact set was heavily pitted and burned. These contacts were carefully cleaned and pollished with 1000 grit sanding paper. The actuator leaves were examined and two sets were found to be slightly out of alignment. The leaves on these sets were bent slightly to insure they were in line with the rest of the leaf serts. It was then noted that the rotating leaf('s) actuator had a home position indicated by a molded depression at one location and the motor was energized using approximately 5 volts ( a nine volt battery could also be used as a poer supply) observing prolper polarity to run the rotator until the home position was established and the actuator rods paul dropped into this depression. The assembly was then replaced in the diswasher using care to make sure that the actuation arm and spring were positioned properly weith the arrow end of the arm located in the recesss of of the rotating timer disk use care in placing the assembly and do not lose the sping which attaches to a mounting post and the arm. You may want to take a picture of the spring and arm locations when you rwmove the timer assembly to properly re-assemble all components, the repaired unit was placed back in its cabinet and a full cycle run to establish proper operation. And unit checked ok! Some of these proceedures are not for the weak of heart. I am a retired engineer who has been repairing my own equipment since graduation. .

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!

Unscrewed unit from counter and loosened legs using adjustable supports under dishwasher. After switching off water under sink and power at circuit breaker, removed motor and pump assembly and replaced with repair kit.

remove bottom tray and rear cover from inside washer.then remove PISTON NUT ASSEMBLY CHECH VALVE by turning it to the left. replaced with new valve assemmbly. IT IS workng like NEW.TOOK ME 30 minutes.VERY EASY!!!!!!!!!!thankyou allfor the help.

I gently grasped the end caps with pliers and twisted them toward the center of the dishwasher while gently pulling on them. They came out with some minor difficulty. Be careful or they can be broken. When putting the caps back on the tracks grasp them with pliers to reinsert. Use a small srewdriver to assist in getting the plastic caps to slide into place. Wear light weight gloves when doing this to avoid getting cut on the sharp edges of the tracks.

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.
