Problem solved....no more water $10 part....no repair person !!!

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. .

took end caps off (one broke) slid in new disk rack and put caps back on.

I disconnected the power shut off water supply. I then removed the drain hoses and water supply to the old pump. I removed the ground wire and the mounting rod to the old pump. Once removed, I followed the easy illustrated diagrams and instructions that came with the replacement pump.
I mounted the new pump using the supplied hardware and reconnected suply line and drain hose. I turned water supply and power back on. Ran a test cycle before reinserting under countertop. Amazingly quiet and no leaks. Repair a success.

I would use this service again if needed for additonal home appliances.

Thank you
Mr. Buddy King

I looked at your web sight and saw how to repair dishwasher.

Your video doesn't include disconnecting water supply disconnecting electrical and disconnecting drain hose but after all that the repair to change the solenoid was a easy task but the problem was not solved so I TRIED . thanks Robert

Removed screen bottom rear andfound a plunger type part, unscrewed plunger and found it was distressed around it and did not close of a tight seal. Placed new part into location and dishwasher now proforms perfect...

repair kit was complete and directions were easy to follow. my model of dishwasher disnt even require any of the adapters. really only required removing a couple of clamps and replacing everything as a single unit

I had a problem where the GE dishwasher would randomly stall upon startup due to a dead spot in the motor which prevented it from energizing. I removed the dishwasher's bottom access panel to inspect it and found that not only was the motor dead but it had a sizable leak emanating from the pump seal. I removed the dishwasher from under the cabinet area and turned it over to make it easier to replace the motor and pump assembly which only took a matter of minutes; the most difficult part of the repair being the reinstalling of the dishwasher. The replacement motor/pump assy was not only modified from the original parts but it is also much quieter than the original. I also have to commend PartSelect on their very speedy delivery which was only 2 days. All in all with a couple of minor modifications that was taken care of with the included parts the repair went very easy.

Recieved universal parts f/ pump & mtr assy. sorted them out, picked the ones I needed to complete my repair. Installed new assy, checked operation and was completly done in about an hour.

My old bones needed a break, or I could have been done faster. All's well, and the dirty dishes are back getting cleaned via machine, and not us.

Installed new motor and pump kit. Very easy, except that the instructions did not give any detail on the electrical hook-up. The problem was that the electrical connections for the motor and solenoid were the same on the replacement kit, making it possible to switch them. Be sure and mark the connections from the old unit before removing them.

Went great, but make sure you install lock for the door on the door cover, not the door and save yourself some time!
