GE Profile Dishwasher Not Cleaning
I removed the outer metal door cover by removing most of the phillips roundhead screws. The two screws closest to the latch should not be removed (they hold plastic pieces that help hold the outer door cover in place during reassembly), and the two flathead screws on the side of the door near the hinge should not be removed yet (they attach the pump). The door cover also has two small hex bolts on the bottom - these should be removed, too (or at least loosened). I removed them.
The outer door cover has two flat flexible wire bundles (for the buttons) that attach to the door using "quick-connect" push-pull connectors. One has a small tab which must be slightly depressed. Gently but firmly pull these out. Set the door cover aside.
I removed the pump by (one) gently but firmly removing the short (2" or so) gray rubber tube from the bottom of the detergent reservoir (NOTE: any detergent remaining in the reservoir will immediately drain on the floor at this time -- I let it drain most of the detergent into a cup, but then I taped a tapered wood screw into the opening to serve as a plug); (two) removing the 90 degree rubber fitting that attaches to the door; (three) disconnecting the motor wire electrical quick-connect; and (four) removing the two flathead screws that attach the pump to the door.
My (rotary peristaltic) pump has a black flexible tube that was clogged with solidified detergent. I verified the pump worked by first connecting the pump to power from the wall outlet. I used an old extension cord, cut the ends, crimped some small connectors that did not fit well to the pump connector, then taped the whole thing to help prevent a shock (I did not feel comfortable with this, but I did it anyway. Use caution. If I have to do it again, I would have used a pipe cleaner or wire instead of operating the pump as described below.). The pump motor is rated 110 volts ac., and the pump was operating fine. I think I got lucky (the pump spun the correct direction). It may be that if I reversed the wires, the pump might have operated backwards.
I then held the pump inlet hose under hot water in the sink for about 10-15 minutes, occasionally squeezing the hose, until the thick detergent had dissolved. During this time, the pump was pumping the water out the outlet.
I put everything back together, and the dishwasher cleans again.
