GMB939JC119 General Electric Dishwasher - Instructions

took out 4 screws pulled piston out and changed put back together. very easy and inexpensive!! thanks

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

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.

Replaced the old hose with new one; very inexpensive part, only cost me 10 dollars. Way better than replacing the entire dish washer. Thank you so much for providing the "do it yourselfer" the items for simple and easy tasks. :)

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.

Pulled out old basket with holes at bottom and replaced it with new basket. Perfect fit!

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.

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.

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 !!!

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

The repair kit solenoid was mounted in a metal bracket. My unit has the solenoid and mounting bracket as one piece. If the solenoid was separate it would have been an easy fix. As it was I had to cut the solenoid out of the bracket to mount it in my unit which this kit was suppose to fit.

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

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
