GSD4910Z02AA General Electric Dishwasher - Instructions

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.

Removed the 4 screws holding the filter screen assembly in the back of the tub. This exposed the Piston and Nut assembly which unscrewed fairly easily.
Replaced with the new part, put the filter screen assembly back in place ran the machine. The machine still stops with the blocked arm message - just not as frequently. The web researched fix with the piston and nut assembly replacement was obviously not the final answer. I am now out of options I believe except to bite the bullet and get a new machine. Any other suggestions are welcomed.

Remove the back filter to access check valve assembly. Twist check valve assembly to remove, not significant deterioration of rubber cap. Install new assembly. Re-install filter. Super-easy and effective!

Remove shield in rear. Unscrew valve using hand. Screw new valve in place.

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.

As per instructions from this site I simply unscrewed the entire assembly and installed the new spray arm assembly. The old unit was a bit stubborn due to age so I used the long handle of my favorite screwdriver, inserted through the bottom area, for leverage. The entire process took less than 5 minutes. Very simple and as a side benefit, the dishwasher operates much quieter than before the old spray arm broke. Guess the old arm was also worn out before it broke on this 18 year dishwasher.

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.

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.

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.

I Just Open Door And Put Fill Cap In And Turn That It

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.

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.

Opened package, removed cap and screwed it in place.

Recieved universal parts f/ pump & mtr assy. sorted them out, picked the ones I needed to complete my repair. Installed new assy, checked operation and was completly done in about an hour.

My old bones needed a break, or I could have been done faster. All's well, and the dirty dishes are back getting cleaned via machine, and not us.

Turn water off and unplug unit first. I remove the 2 retaining screws under counter, pulled out dishwasher. I laid it on it's side to get to pump, loosen up Hose clamps on inlet and outlet ports on pump. You may need a towel or rags to soak up a small amount of water from hoses and old pump. Removed the two hoses on the side, note the lowest one is the drain hose. Un plug all wire connections and loosen support bracket. Removed old pump and installed new one in reverse order. I had to use the 90* adapter hose and the white adapter for my drain hose.The kit contains all adapters and it all fits perfect. Reinstalled and tested unit worked great!!!
