GSC3430F00WW General Electric Dishwasher - Instructions

Removed the 4 1/4" screws holding the rear screen to the bottom of the inside of dishwasher. "Piston & Nut" assembly was badly corroded- to the point that no dirty water was leaving the dishwasher. Because the appliance is at least 10 yrs old and there was nothing happening during the rinse cycle, I initially assumed the worst- that the pump was bad. After reading the other descriptions of the problem here, I said, "what the hell?, if a $20 part fixes it, I'll be amazed- if not, I'm out $20 and looking at another $300 for a new dishwasher!" The $20 part (inc. shipping) did the trick. Thank you, and your website is on my "highly recommended" list! One note- the piston & nut assembly did offer some resistance as you might expect after being "gunked" in place for 10 years. However, the top has some lugs or ears built into it, so a few taps with a hammer on my largest straight-blade screwdriver loosened it right up...

follow instructions found here, with a little help from part diagram. Initially removed the sump cover but then removed the cover at the back of tub. This uncovered the Piston assembly and the replacement was a snap. Dishwasher now works well and actually cleans the dishes. Also did I mention my parts arrived the day after I ordered even though I used standard delivery. This site rocks.

Unplugged the machine then removed the two connectors to the motor. Loosenned the hose clamps, pulled the hoses took off the balancing bar,removed old motor assembly and put new one in. Reverse all the steps plugged the machine back on and was done in less then twenty minutes.

Very, very easy to insert part.

removed piston in filter and replaced. the check valve had come apart and was not sealing

First I removed the four screws from the screen/cover located at the back of the dishwasher. You will notice a mesh screen in the center of this cover. The check valve is under this cover midway between the sides. The check valve is unscrewed counter clockwise. I had to use a pair of pliers to start turning the valve. There are two "ears" on the top of the valve. You will see a rubber cone shaped piece that should completely cover the opening when the plunger is depressed. In my case the rubber was almost completely gone allowing water in the drain hose to return to the dishwasher after the drain pump stopped. The new check valve threads back into the opening and should be finger tightened. Replace the cover/screen and you should be good to go.

Most time spent was removing washer out from beneath the counter. Motor and pump installation was a breeze. Everything I needed was in the kit and easy to follow the instructions provided. Saved a lot of money and washer runs perfect. Thank you.

Removed the dishwasher from under the counter, found where the leak was coming from, which took the most time. We ordered the new part on line, it came the next day and the installation of the new part took about 30 minutes and the dishwasher is like new now. This procedure saved us a lot of money.

Replaced the Piston and Nut Assembly, located inside the dishwasher under the screen at the back, by unscrewing the old one and replacing with the new - Works great now!!

Assistant helped me take apart unit, assumption on issue was correct, part was ordered and showed up 3days later. I installed and all seems fine. I do question what would have happened if the deduction was incorrect. The assistant was very patient and clear with his instructions. A good experience!

I disconnected the water line on the left-front. Disconnected the drain line at the air-break. I removed the AC power-in box on the right front and disconnected the power lines going to the unit. I took out the two screws holding the unit to the cabinet (above the door) and slid the unit out onto a drop cloth (protect the floor; some water spills). Pulled the unit out and turned over. Followed the directions with the motor & pump valve kit, which were very easy to follow. Then reversed the above. Nut drivers are a must for this job.

The repair went really smoothly, I found a video on youtube for how to remove the dishwasher, and the video on the parts page did a great job covering replacing the motor. The repair went really well. As others have noted, it ran really nosily the 1st time, and a little the 2nd. After that, it ran quieter, and stronger than it has in the 4 years we have owned the house.

I reinstalled a new piston/nut assembly which was easy as per this forum. The two compared side to side clearly showed my old one as worn out and deteriorated. This however wasn't the only problem. Once new piston/nut assembly was installed the water still did not drain. I pulled the dishwasher out from the cabinet, disconnected the hose connected from the pump to the outer box the piston/nut assembly connected to and flushed that out. I discovered two pieces of broken glass in the box that may have been blocking the rubber flapper connecting the box to the drain hose. Glass was removed and once all was reconnected the unit drained perfectly. Check for potential debris in outer piston/nut assembly piece if simple change out of of piston/nut assembly doesn't solve the issue.

Followed previous directions which were easy. Hard on back trying to reach over door all the way to the back. My DW is over 15 yrs old and the plastic plug w/corroded and locked into place. Tried turning it by hand to no avail since the plug turning lips were worn off/or not long enought to grasp it with. Took a hammer and chisel to the lips and turned it about an inch counter clockwise (either way), then lifted it out prying it with a screwdriver. KEEP IN MIND THE THREADS ARE JUST FOR LOCKING IT IN PLACE AND THE PLUG CAN BE TURNED EITHER WAY. IT DOES NOT SCREW IN!! Cleaned it with DW40 and reassembled it.

Removed the existing inner door by removing screws along the edge of the inside door. Had trouble removing the door latch but after lifting it on one side of the plastic door fitting, it eventually lifted out. I also had some trouble getting the spring loaded soap door back into the replacement inner door. After playing with it for awhile I realized that the soap door should be in the open position when putting the spring latch back on. The soap door won't close until you get the entire inner door mounted and back on. I also want to note the the inside vent in the upper part of the inner door needs to be removed from the old inner door and installed in the new one. I missed that at first and it allowed condensation to get inside the door which caused the dishwashers alarm to go off during the dry cycle. One last note that I initially decided not to replace the existing sound proofing material in the new door based on advice from a website that stated that I wouldn't notice the sound difference. That was definitely untrue. I had to disassemble the door, replace the sound proofing and then it sounded fine. Overall it was a little difficult to figure out but considering how inexpensive the replacement door was compared with a having a service repairman come out, it was worth the trouble.
