GMB939JC119 General Electric Dishwasher - Instructions

I had never done work on my dishwasher - I was a rookie in this area. Turns out the work itself was quite simple. Pulled the dishwasher out, turned it over, and was able to easily replace the motor and pump assembly. The drain tube was also an easy replace. A couple key notes:

1. I also purchased a new drain solenoid and impeller kit. Note that both of these items are already included in the Motor and Pump kit replacement. There is no need to by both, now I have extras.

2. The end of the drain tube has to be trimmed if you are routing the drain tube to an air gap mounted on your kitchen sink. You have to cut the large diameter end of the tube to get to the narrow portion that will fit on your air gap.

3. The first cycle you run with the new motor/pump assembly is noisy. When you first fire it up the components in the pump are all dry, and they squeal until the water gets to them. I initially thought I had done something wrong, but once the water started flowing all the peculiar sounds cleared up.

I removed the four screws holding the screen and molded plastic cage inside the rear of the dishwasher to expose the check valve assembly. I then unscrewed the piston and nut assembly with my hand and replaced it with the new one. I found that the rubber cone shaped valve on the old piston and nut assembly was entirely disintegrated. This easy repair solved the problem.

1. Remove lower cover skirt.
2. Shut of water at undersink valve.
3. Unplug power cord or turn off circuit breaker.
4. Disconnect water supply line from fill valve.
5. Unplug the electrical connector from the valve.
6. Remove the 2 valve mounting bracket screws.
7. With loose valve in hand, rotate to gain access to allow release of outlet hose clamp for hose removal.
8. Remove brass fitting from old valve and install on new valve. Use teflon tape on the pipe threads only.

Install new valve by reversing the procedure.

The most difficult part was removing the dishwasher from below the counter. Once that was complete, I simply turned the washer onto it's front surface to access the pump easier. Simply disconnected the electrical connectors, loosened the three hose clamps holding the hoses to the pump. Lastly removed a stiff arm bracket holding the pump. Reversed the order to install the new one using a longer bracket provided with the new unit. Hooked up the electrical connections last and slid the washer back in place. The washer runs like new now and is not making noise. The replacement part was a perfect match.

unscrewed 2 screws found on upper part of dishwasher that connected hose to spray arm found inside of dishwasher to remove hose. gently squeezed rubber gasket to work it into the hole found at the top center of the dishwasher, made sure rubber disc shaped gasket was seated properly into spray arm, screw spray arm back into place. The job was much easier than I thought It took about 20 minutes it saved me from buying a new dishwasher, the delivery of the hose was faster than the speed of light it took about i business day, I order the hose on saturday it arrived tuesday evening. Thanks for your excellent service

took dishwasher out- put on table to work on-removed wire brace- disconected drain outlet- disconnected top drive seal- removed wire clip connector- removed motor unit----------------
installed new motor/drain unit--used new longer wire brac used adapter to connect electical leads-
tightened clamps and bingo it worked and didnt' leak. good job on the supplying of all the necessary adapers.

Did the install a few days ago 4.25.11 and all went smoothly. The instructions that came with the kit were very straightforward and the diagrams were extremely helpful in locating brackets/hoses/connections. My dad thought he would just get down there and do it, but wasn't sure what to do. Using the directions with the kit, I had the motor and pump off in under 5 minutes. FOLLOW THE DIRECTIONS WITH THE KIT!

Some things to note:
- Get some towels/cups/bowls, we had some water leaking from the dishwasher and hoses.
- Be careful removing the dishwasher from the counters, go slow.


1. Shut off electricity
2. Shut off water. I just shut closed the line that went directly to the dishwasher.
3. Removed screws from bottom panel to expose motor and pump assembly.
4. Removed screws securing the dishwasher to the counters.
5. Slowly slid dishwasher from counter and rotated so door was facing the ground carefully to ensure wires/hoses were not pulled or crushed.
6. Removed screw from bottom of motor that was secured to the hanger.
7. Removed ground screw from bottom of motor.
8. Removed all wired connections from the motor and pump.
9. Loosened hose clamp securing the drain line and removed from motor.
10. Loosened 2x hose clamps securing the motor and pump assembly to dishwasher.
11. Ensured everything was clear and disconnected, and slowly removed motor and pump assembly from dishwasher.
12. Test fit new motor and pump assembly.
13. Reconnected 2x connections to the motor and pump.
14. Secured the ground wire to the motor and pump.
15. Slid motor and pump onto dishwasher and secured the 2x hose clamps.
16. Secured screw from the hanger cable to the motor and pump.
17. Reconnected water line to motor and pump, and tightened hose clamp.
18. Ensured all connections were made, hose clamps were tightened, and there were no extra connections.
19. Rotated dishwasher back onto feet.
20. Slowly slid dishwasher back into counters ensuring no cables or hoses were kinked or crushed.
21. Restored electricity and water to dishwasher, and then performed a quick test of one cycle to check for leeks.
22. Secured bottom panel and dishwasher to counters.
23. Enjoyed having a working dishwasher again!

Ordered the part, by using the diagram on the ge website identified the part and ordered it right them and when it came (delivered really fast) took it out of the bag and screwed it in the jet dry despenser and is working great.

The hardest part was removing the dishwasher from under the counter and cleaning up the large amount of water that poured out when I turned the unit on its side.
The actual pump replacement was pretty easy except there were a lot of extra parts that were only needed for other brands or other models.
I might have tightened one of the large clamps too much as there was a very slight leak after I was done. One or two drops of water per cycle, which evaporates quickly and not worth taking apart again.
It was not hard but took longer than predicted.
Much better than buying a new dishwasher or paying the estimated $350 to an appliance repair company.

Rather than remove the dishwasher from the counter, I performed the repair inplace, which was much less work (although I did have to lay on the floor).
After turning off the power, I removed the two access panels at the bottom of the unit, disconnected the wiring from the pump and solenoid, loosened the drain hose fitting and drained most of the water out of the unit and into a shallow pan (the drain solenoid was stuck open, so this was pretty easy - otherwise, I still could have manually actuated the drain valve & solenoid to drain water through this hose).
There was alot of water in the unit and my pan overflowed a little. If I was doing this again, think I would have disconnected the drain hose from under the sink and drained out through that into a bucket (I could have controlled that flow better).
Once the water was out, there are just two hose clamps that hold the pump onto the unit (one on top and one in the back), and a stabilizer bar that connects the motor to the front frame. Removed these and the whole unit came right out.
The replacement pump & motor was exactly the same as the one that came out, so I didn't need any of the hose or wire adapters that came in the kit.
Reconnected the two pump connections, motor bracket and wiring, and the unit was good-to-go!

Removed bottom tray from the dishwasher and in the back there is a screen with 5 hex head screws. Removed the screws and then lifted the screen out to expose the vavle. Unscrewed the valve by hand an installed the new one,hand tighten only. Reversed order for reassembly.

Found great information on this site describing the problem. My 9 year old GE Triton dishwasher has not been draining. I thought at first it was something stuck in float somewhere or perhaps a bad pump, but after searching around, I found this site and other stories similar to mine. Most of the reports suggested a worn check valve in the floor of the dishwasher tub, apparently a common issue with some GE models. I removed the strainer located at the back of the tub (4 screws removed w/ 1/4" nutdriver), then unscrewed the check valve to inspect it. Saw that the valve seat was very worn. Ordered the replacement part, received it 4 days later and installed in less than 10 minutes. The best part was I didn't have to remove the dishwasher or crawl underneath to complete the repair. Well worth the $20 for parts & shipping.

1. Remove access panel under door. 2.Shut off hot water.3. Shut off electric to washer.4. Disconnect water line from water inlet valve.5. Remove small outlet water line from valve. Replace valve & reconnect. OR !!! 1.Take solenoid valve & bracket off of original inlet valve 2. Pull out white plastic diaphragm cover. 3. Remove diaphragm & clean out water holes with a pin. 4. Reassemble valve. 5. Reinstall original water inlet valve & save $27.00

I removed the four screws of the filter frame exposing the check valve (piston and nut assembly) . I unscrewed the old check valve and replaced it with the new one.
