GSD3920C05BB General Electric Dishwasher - Instructions

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 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.

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.

Literally 1 minute to replace. They are perfect and an easy fix for split tongs on the wine glass holders

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.

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
Mr. Buddy King

Your video doesn't include disconnecting water supply disconnecting electrical and disconnecting drain hose but after all that the repair to change the solenoid was a easy task but the problem was not solved so I TRIED . thanks Robert

took end caps off (one broke) slid in new disk rack and put caps back on.

repair kit was complete and directions were easy to follow. my model of dishwasher disnt even require any of the adapters. really only required removing a couple of clamps and replacing everything as a single unit

I looked at your web sight and saw how to repair dishwasher.

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.

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!

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.
