Dishwasher wouldn't drain
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

Leak when dishwasher drains
The leak was coming from the drain valve shaft and I found the tips to replace the seal from this website. I was able to reach everything without removing the dishwasher from the cabinet. Once I got the cam lifter off the old push on nut was corroded so it was easy to get off. The old seal was recessed so I used the point of an ice pick to gently pry it out. The new seal was easy to push in place but the push on nut was a bear. I saw other comments about using a deep socket to push it on but I didn't have one the right size. I was able to hold the end of the shaft with pliers and pushed the nut in place using a screwdriver. Ran a short cycle and no more leak. Thank goodness for this website. Found the part easily and the other written comments were very helpful.

Door Leaking
On the GE Pot Scrubber 1120 model you do not even need tools to replace the parts that we replaced. We just pulled the corner baffles out and cleaned the corners before placing the new baffles in. For the door gasket, we just pulled the old gasket out and put the new one in the track that the old one came out of. We didn't have to take any door screws out to replace the gasket at all. It was very easy to do and no more leaks. You will have to push against the door to get it closed tightly the first time you use it since the new gasket has not been flattened by use. I ordered the gasket insert and used it since we had it but for this model we didn't really need it. I would suggest not ordering one for this model.

Appliance door would fall open and was heavy to close
I first removed four screws holding the two cover panels attached to the dishwasher front at the bottom. Next I removed the broken cable and put everything back together that had sprung apart when the cable broke. Then I inserted the two door springs ends into the cable slots. Next I pulled on the springs to create slack and attached the cable / eyelet assembly to the protruding tab on the dishwasher frame. After attaching both sides the door works perfectly.

Dishwasher would not drain
I simply removed the front toe kick panels.
The solonoid is staring you in the face.
I removed the small nuts on back side of the solonoid bracket and removed the retaining clip and springs.
I installed the new solonoid and was very surprised how easy it was.

I DID turn the power OFF at the breaker panel prior to starting the repair.

dishwasher wouldn't drain all the way
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.

Broken Roller
I watched the video and did exactly what he did. I am a novice when it comes to repairs. I learn as I go. This repair went flawlessly. Ordering was quick and easy. The part arrived quickly. The repair took less time than expected. The part was what I needed and nothing else broke or went wrong when repairing the original problem. It was a 100% success.

water leak due to bad rubber connector
Ordered rubber connector and it arrived the next day. Shut off main power and water. Disconnected water supply and pulled unit out from under counter. Flipped unit over on it's side. Disconnected wiring, drain hose, clamps and completely removed motor/pump. Rubber connector would not unscrew by hand so I found a drinking glass slightly smaller in diameter than the connector inner diameter. Inserted glass in connector and proceeded to unscrew connector by turning connector and glass together. After removing old connector I cleaned the mating part after removing it from inside the washer and removed all the build-up. Replaced everything back in same order.
