GSD3900L20BB General Electric Dishwasher - Instructions

I found that the supplied part did not have threads to receive the bolts that were used in the original part. I had to locate thin nuts and bolts and very awkwardly fit those in behind the part. The orignal part would have just bolted on from the front. I almost returned the part as unsatifactory, but decided to make do. Otherwise it would have been a 10 min job.

I pulled the dishwasher out and detached the drain hose. I attached the new drain hose after cleaning out the connection to the garbage disposal.

Now my dishwasher doesn't stink anymore!

It is pretty easy to replace the parts because the new and old parts are identical. I unplugged wire connection, removed the two screws and one small metal piece that fixes the plastic moving part, then put back with new parts.
A little bit extra time may needed due to small space in that location, also the small or flexable screw driver is needed.

Disconnected the electrical, water supply and drain. Pulled unit out from under counter, tipped it on its side and replaced the motor/pump unit. tipped it back on its legs put it back under the counter connected the water supply, drain and electrical. All went well. The unit performs as it should. it took about two (2) hours without rushing through it.

Opened the package and screwed in the new rinse aid fill cap. No problems. It fit and works just fine.

My son found a water leak and cut the water supply off. He then pulled the machine from under the counter at which time I examined the valve under pressure and saw the leak. We cut the water off again and after tripping the circuit breaker we pulled the electrical connector and undid the mounting bracket which made getting the lines off the valve much simpler. New valve in hand I attached the lines and did a test then remounted the bracket and attached the electric. Easy as pie!

At first I found some water on my hardwood floor by the dishwasher, I thought that I might spilled't the day before, then it hapened again, so I remover the front lower cover for the dishwasher and I found water under the dishwasher, then I turned on the machine and I found a pin hall water leak from the water inlet valve. I turned the machine off, then I closed the water valve under the sink, then I disconected the power plug from the valve, the diconected the water supply copper pipe, then diconected the house from the valve to dishwasher, then got the part# from the valve sticker and the model# for the dishwasher from inside of the door. after that I went online and I got the valve. make sure to try more than one website because they all have differant prices, and Parts Select was the lowest one.

First I looked for blockage and found none.I took the pump off and hooked power to it in my work shop and it did spin when powered up.We had broken a glass in the washer and thats when the problem started. I did find a few small pieces in the check valve assembly. It did not look bad but for cheap I ordered the part. Ran the washer and it drained on the wash but not on the final. Turned off the power.Slid the wash out where I could get to the power and not unhook the water. Turning off the power I disconnected the wires and carefully turned the power on and touched them to the pump and forced it to drain knowing that the pump worked I thought it would at least empty the water. I touched the wires to the pump and the board clicked the water drained. Hooked it back up. Ran it and has been working great since.

Once the new motor and pump kit arrived. I removed the dishwasher, turned it upside down and replaced the motor and pump with the new one per the directions. Difficulty came in feeding the electrical wire/plug back through the cabinets. Once done, turned on the dishwasher, filled the tub, then manually moved the dial to drian. The water still would not drain from the tub. I searched further for the problem. Here it is; Found the air gap tube was plugged with food. Once I removed, cleaned and reinstalled the air gap, the tub drained fast and everything works great. So, I hope you folks put this up in your troubleshooting section for others to check before buying a pump and motor kit. If you had, I would have been able to check out the air gap, clean it out first before spending $140.00 for a pump and motor kit I didn't need. Anyway, lessons learned..Jeff

Replaced with a new rinse aid fill cap.

Removed 4 screws, took off basket covering, put new part in one turn, then replaced covering. Plumber had come out, I watched what he did, he had to order part and come back. I asked how much he didn't know but said cheaper than buying a new dishwasher. When he left I started calling around about the little plastic part that I needed. Part was $15.50. They called and said it would be $110.00. Needless to say I called them out and ordered the part myself and put it in. Took me like 6 minutes and cost $21.69. I was so mad about this situation that I even got my service call money back that I had already paid.

Removed the old one from its slot and slid the new one into it.
No instructions needed.

I used the website to identify a few different problem areas. I found that the motor shaft would not turn. Upon removing it, it did turn, which lead me to look at the Impeller which was worn / frozen. Ordered new impeller and installed 100 % success !!!

First I removed the four screws that secure the dishwasher to the underside of the countertop. Then I removed the four screws from the front cover at the toespace. Next I used an adjustable wrench to turn the feet to lower the unit enough to slide it out of the compartment. I unplugged the dishwasher and turned it on its side in order to access the hose chamber. I used a pliers to loosen the clamps at each end of the hose chamber and removed the the damaged item. Next I slid the ends of the new part into place and used the pliers to reposition the clamps. Finally I returned the dishwasher to an upright position, slid it back into the compartment, adjusted the feet to raise it to the proper height, put the toespace cover back on, secured the top of the unit to the underside of the countertop and I was good to go. No more water leakage.

The repairman offered to fix the dishwasher at a cost of about $200 or supply the water inlet valve for $85. Google led me to PartSelect.com where I easily found the correct part for $45. I received the part in 2 days by FedEx ground.
The hardest part of the repair was removing the dishwasher from the cabinet. I took the dishwasher out a short distance to the patio where I replaced the water valve...about 10 minutes.
I then made a makeshift connection to an outdoor water hose and connected the electricity and ran the dishwasher while out on the patio through a short cycle to make sure of the repair and check for leaks.
Then reinstalled into the cabinet...total time about 2 hours.
