GSD4030Z04WW General Electric Dishwasher - Instructions

Removed filter screen with the socket set, removed the piston and nut assembly with pliers, and installed the new piston and nut assembly. Put filter screen back in with hex head screws. During the process, I opened the float regulator and cleaned it out too. Water backup problems solved.

Remove the back filter to access check valve assembly. Twist check valve assembly to remove, not significant deterioration of rubber cap. Install new assembly. Re-install filter. Super-easy and effective!

Removed the 4 screws holding the filter screen assembly in the back of the tub. This exposed the Piston and Nut assembly which unscrewed fairly easily.
Replaced with the new part, put the filter screen assembly back in place ran the machine. The machine still stops with the blocked arm message - just not as frequently. The web researched fix with the piston and nut assembly replacement was obviously not the final answer. I am now out of options I believe except to bite the bullet and get a new machine. Any other suggestions are welcomed.

remove the screen at the back bottom of dishwaser. (4 screws). Unthread piston and and nut assembly for check valve....thread in new one.
Problem solved....no more water $10 part....no repair person !!!

Remove shield in rear. Unscrew valve using hand. Screw new valve in place.

A no brainer, replaced old fill cap with new fill cap. Delighted I was able to order the part, website is user friendly.

Followed the simple instructions to unscrew the old unit and replace with the new one. The unit was easily located on a diagram on the internet and the website instructions for removal were spot on.

First I removed the bottom dishwasher rack. Using a 1/4" nutdriver I removed (4) 1/4" screws from the drain cover that is inside the dishwasher all the way in the back. This will allow you to get to the piston and nut assembly which was easily removed with no tools by simply grasping and unscrewing. Used a wash cloth to wipe "gunk" from around the threads. I then screwed the new piston and nut assembly in place. Used no tools to tighten, just "snug up" by hand. The seal on my old piston and nut assembly was 50 percent gone, not sealing at all. I guess the years had taken their toll. This solved my problem. The dishwasher washes and drains as it should. Super easy fix. Took me about 10 minutes to do the repair.

Unscrewed bottom of spray arm support assembly counterclockwise by hand for removal. Inserted new part and screwed it in clockwise by hand for installation. Worked perfectly. Video was helpful.

Removed filter/screen by unscrewing 2 screws with a nut driver and then unscrewed the old Piston and Nut assembly and simply screwed in the new part. Problem solved and my dishes are much cleaner and the water is draining out completely. Easy fix for this frustrating problem.

The repair could not have been more easy! We simply unscrewed the broken spray arm and screwed in the new one. For less than $50, we fixed it ourselves. We would have paid in excess of $350 for the repairman to fix it. We could not be more happy with this website, the videos and the fast delivery!

Loosened the clamps connecting the pump, disconnected all electric and stabilizer arm. Simply unscrewed the solenoid bracket and replaced with new part.

Used Phillips screwdriver to undo brackets that keep dishwasher in place. Pulled out dishwasher from underneath the counter. Placed hinge arm in spring, hooked spring onto clip, placed hinge arm in clip. Put back dishwasher under the counter and screwed in place. Took all of 15 minutes. Saved 185.00 for service call.

took out 4 screws pulled piston out and changed put back together. very easy and inexpensive!! thanks

The replacement of the motor and pump assembly went smoothly and without difficulty however this did not fix the problem. It then appeared that the inlet water valve was not operating properly, so this part was ordered and instlled, a very simple proceedure that could be done witrhout removving fthe dishwasher from its cabinet. -- Again failure to run -- the timer assembly and electronic panel were then removed and examined. The control panel had no visible defects, so the timer assemblyand its cover was removed and examined . Uing a variable power supply the drive motor for the timer was energized and tested. As the motor ran properly the electrical switching contacts were then carfully checked, it was discovered that one contact set was heavily pitted and burned. These contacts were carefully cleaned and pollished with 1000 grit sanding paper. The actuator leaves were examined and two sets were found to be slightly out of alignment. The leaves on these sets were bent slightly to insure they were in line with the rest of the leaf serts. It was then noted that the rotating leaf('s) actuator had a home position indicated by a molded depression at one location and the motor was energized using approximately 5 volts ( a nine volt battery could also be used as a poer supply) observing prolper polarity to run the rotator until the home position was established and the actuator rods paul dropped into this depression. The assembly was then replaced in the diswasher using care to make sure that the actuation arm and spring were positioned properly weith the arrow end of the arm located in the recesss of of the rotating timer disk use care in placing the assembly and do not lose the sping which attaches to a mounting post and the arm. You may want to take a picture of the spring and arm locations when you rwmove the timer assembly to properly re-assemble all components, the repaired unit was placed back in its cabinet and a full cycle run to establish proper operation. And unit checked ok! Some of these proceedures are not for the weak of heart. I am a retired engineer who has been repairing my own equipment since graduation. .
