GSD3910C04AA General Electric Dishwasher - Instructions

First I removed the dishwasher from under the counter. I turned it onto it's side so I had access to the motor and pump underneath. I determined which version of the old pump I had. I removed the old part and easily installed the new motor/pump following the directions. It took a little while for the water to begin flowing when I started it back up. Eventually it did get going.

The motor seized up on my 1990 GE Dishwasher
Repair would cost 360. Replacement about 600
I ordered the motor and pump from PartSelect for 137..44
Remover the under counter washer (it‘s very light) and removed the water and drain line and disconnected the power. Turned the washer on it’s top to access the motor and pump and removed the electrical plug in lines, and the clamps holding the pump on to the connections. Replaced it with the new motor and pump, reconnected the electrical plug ins, added an adapter hose part, tightened the original clamps then reconnected the water, drain and electrical connections and reinstalled the washer. All in about an hour, The only glitch was the grounding screw for the ground wire on the motor. The screw was too long to tighten. Substituted the original shorter ground screw from the old motor, and that worked fine. Only used 4 parts from the large assortment of parts supplied.
Immediately ran the washer through a cycle, all worked perfectly.

Unscrewed the old spray arm (I needed pliers but you may not need them)and screwed on the new spray arm.

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

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.

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 !!!

Unplugged unit, unscrewed screws on top of dishwasher attached to countertop, undid water supply and drain hose that goes into tee with garbage disposal. Using crescent wrench turned front leveling screws up all the way and slid/rocked dishwasher out from under the counter - I had no problem leaving back leveling screws down. Turned dishwasher over on some towels (it WILL leak some water so spread out some towels!) so it was oriented like the directions that came with pump and motor. The directions were good, although color or a picture might have been more helpful. CHECK the new pump/ motor unit CAREFULLY for any loose debris from packing etc. I had a small piece of plastic that was in the top of the motor that goes in the dishwasher bottom that rattled around after I installed everything and put it back. I was able to get to it from the drain assembly in the tub but it made a heck of a racket at first. All in all, I had a great experience. I'm glad I ordered the pump and motor even though I only thought I needed the drain solenoid because when I took the old unit out, the prop on the old impeller was almost gone. Easy to order, good customer service (I called with a question and talked to a wonderful customer service representative!), good directions and easy to do. I'd say a 4 out of 10 in terms of difficulty. Thanks PartSelect!

Took four screws out, unscrewed the piston & nut assembly by hand installed the new one. Cycled the dishwasher & it worked perfectly.

First I opened the package and screwed the new dispenser cap into place.

Disconnect water line and screws (2) holding dishwasher under cabinet, and clamp for wastewater line. Pulled dishwasher out, turned on its side, and removed pump. Disassembled pump per instructions (great instructions) and installed new parts. Reversed to reassemble and except for a loose clamp that leaked (I tightened) it went well. Just under 1 hour.

The Solenoid black plastic had melted around the solenoid shaft. I unplugged the solenoid, removed 2 screws,then one C clip and pulled the the unit out. The new solenoid is difficult to install all together as the shaft it goes on holds it all together when both springs are installed - - so I installed in one piece, with the 2 screws, except for the white plastic thing, the C clip that holds it on the shaft, and one of the two springs - - these three items went on separately. I wanted to thank the help your expert gave, but I couldn't figure how to do that.
