GSD3420Z04BB General Electric Dishwasher - Instructions

The repair went smoothly. There were actually instructions included with the parts, so that was nice. The only "gotcha" I found was that . . . after you take off the old food-chopper, you have unscrew the old impeller from the motor shaft. This was a bit difficult and you'll want some good pliers to do it. Don't worry about stripping where the food chopper screwed on-to, that part is attached to the impeller and there is a new one on the new impeller. When I re-installed everything onto the dishwasher, it rattled the first couple of times while the wear-ring was finding it's seat. Don't worry, that's normal. It went away by the third wash. I think I still have a small crack in the pump housing, though. The pump housing is two halves of molded plastic fused together along a seam, and I think the seam is starting to leak. It's about one drop every 45 seconds. I'm thinking JB Weld will fix it.

Since the pump and the motor was a single unit, I removed the assembly by disconnecting the electrical plugs and drainage connections. This was a very simple installation. I reversed the above steps, reinstalled the dishwasher and all worked out well.

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

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.

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

Replaced with a new rinse aid fill cap.

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

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 !!!

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

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.

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.

Removed door panel. Removed old door seal and cleaned seal recess. Installed new seal. Replaced door panel on door and ran a cycle to check for leaks. Readjusted door latch to correct small leak. Ran another leak test. Job complete and wife is happy!

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.

Only getting "humming" sound from dishwasher. Although water had filled the dishwasher tub, pump/motor would not operate. After some research, figured the motor had siezed and I had to replace the pump/motor assembly as mentioned on this site. The kit came in a couple days and I reserved a Sunday afternoon for the repair which I had never done before. Hardest part of repair was unhooking and removing dishwasher from under counter and then getting it back in proper place. I would suggest providing some instruction within the repair instructions showing how the dishwasher is installed or how to remove it as I had never installed one so I was not quite sure what screws etc I needed to remove on the dishwasher itself to start to remove it? I was able to find the original installation instruction for the dishwasher and found that all you had to do was remove two screws from the inside top of the dishwasher which were securing it to the bottom side of the kitchen counter and then the whole thing just slides out. Once removed, turned dishwasher over to access bottom where pump/motor is located. After determining which diagram to use with the instructions, proceeded to replace the motor/pump assembly. It came out easily after wrestling with some corroded bolts/nuts and the existing pump inlet and outlet hose clamps. Mine were old and worthless and no new ones (3-4") are supplied with the kit. Had to run to hardware store to get new hose clamps for the inlet/outlet of the pump before intalling new one. Suggest new hose clamps be provided with the kit. Only thing that was not too clear in instructions was when reconnecting power wiring harness to motor. By looking closely at the instruction diagram I was able to locate what looked to be the right power extension harness from the bag of parts and attach it to the existing power wire harness and the new motor. Suggest also that you somehow better distinguish or identify the proper way the power wire harness should be fastned to the motor? The existing power wires were both the same color and both the female and male connections for the power at the new motor were identical leaving you to guess which wire goes to which connection. After re-installing dishwasher, put about a gallon of water in bottom of unit prior to starting and then put it through a few cycles. It has been working just like new. Suggest having a helper when removing and re-installing dishwasher from under kitchen counter to assist with the power cord, water line, drain line, and help to turn the dishwasher upside down and right side up again.
