GSC3200J01BB General Electric Dishwasher - Instructions

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.

After two repair people were unable to solve the problem, I read similar stories in your forum and decided to replace the check value as a last ditch effort. Looking at your diagrams it seemed like an easy repair. Removed four screws with nutdriver and replaced value by hand. Ran washer three times and water drained completely. Still puzzled that this wasn't the first thing a repair person would check.
Websight very 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.

remove the screen at the back bottom of dishwaser. (4 screws). Unthread piston and and nut assembly for check valve....thread in new one.
Problem solved....no more water $10 part....no repair person !!!

First i removed the front cover from the dishwasher then i reached under dishwasher and removed the hose ,then installed the new one. the hose was different size on each end. it took a factory hose to fit it. The diagram that partsselect showed of the dishwasher (the breakdown) made ordering the right part a breeze. Thanks PartSelect.

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.

Your site is great! Saved me a service call for a repairman to come out and tell me what was wrong, order parts and then come back. Total repair was less than $90 including parts and shipping. It arrived in two days from when I ordered it. I ordered the replacement door gasket, the gasket insert and a new checkvalve. This was a super easy fix and I am a girl too boot! I am proud of myself!

I used a phillips screwdriver to take off about 8 screws off the white inner door fascia in order to replace the door seal. Keep this panel upright and do not lay it down since the rinse agent will leak out all over! Found out that the hard way.

Removed the old, dried out, outer door gasket, centered the notch that was on the new gasket at the top of the door and installed it all the way around in the door gasket groove. Installed the gasket insert at the bottom where the door gasket comes together on the bottom of the door.

After that was completed I used a 1/4" nutdriver to remove the 4 hex screws at the back of the dishwasher for the cover that is over the check valve. It is white and has a very fine mesh screen.. so easy to identify.

The old check valve was filled with crud and and the rubber was deteriorated. I just backed the old one out counterclockwise and put in the new one, a little better than finger tight. Replaced the cover and the hex screws with the 1/4" nutdriver.

Reinstalled the white inner door panel, insure the door handle comes through the hole in the front prior to attaching your screws back in place. Closed the dishwasher. Ran it on rinse/hold cycle to make sure no leaks before going for a full wash. Works great and drains now too.

Your site is a lifesaver! Thanks!!!

First I removed the bottom dishwasher rack. Using a 1/4" nutdriver I removed (4) 1/4" screws from the drain cover that is inside the dishwasher all the way in the back. This will allow you to get to the piston and nut assembly which was easily removed with no tools by simply grasping and unscrewing. Used a wash cloth to wipe "gunk" from around the threads. I then screwed the new piston and nut assembly in place. Used no tools to tighten, just "snug up" by hand. The seal on my old piston and nut assembly was 50 percent gone, not sealing at all. I guess the years had taken their toll. This solved my problem. The dishwasher washes and drains as it should. Super easy fix. Took me about 10 minutes to do the repair.

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.

A no brainer, replaced old fill cap with new fill cap. Delighted I was able to order the part, website is user friendly.

After aligning the new knob shaft to the slotted hole and with a slight inward pressure, it snapped right in place

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

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.
