PDT720SGH7WW General Electric Dishwasher - Instructions

Replaced old gasket with new one. More difficult than expected, because new gasket was much stiffer than old one. Also, the yellow centering spot on gasket (to line up with top latch) was nearly impossible to see. Unfortunately, this did not solve the problem for me, so money was wasted. Bought new dishwasher.

The pump went out after a few months of very loud noise during the drain cycle and then one day no drain or noise. A bit of research shows that this pump goes out frequently on this model so I ordered a new pump after inspecting the old pump for a clog or snag on the rotors.

The Install:
After removing the dishwasher from it's installed location and turning it on it's side (unplug water and electric of course), I was able to remove the pump from the two lines that connected it to the dishwasher and the drain line. I also had to unplug the pump from an electric connection to the dishwasher. Swapping out the new pump was the same but in reverse. Not a hard install, only simple tools required.

One note, my electric connection to the dish washer was different on this model pump since they changed the original part but there is an adapter included with this part so make sure it is in the box and fits before beginning.

Simply pick the basket up to slide wheels onto axles and push in until they lock in place.

took off 2 sheet metal on the bottom, lowered the dish washer, pulled it out enought to unscrew 2 screws, unplugged the old part plugged in the new, put it back together.
Works like a champ.

Not having to screw with the hose clamps is the advantage here!
Disconnect electric connection at motor.
Slightly bend tabs that hold the pump to motor, twist motor from volute.
Do this on old pump first to get a feel for how easy the tabs can be broken
Do same on the replacement pump, put new motor on, watch alignment
can be a bit tricky.

The pieces just twist and snap together. You have to align the conduit with the interacting items before sliding and snapping into place. The problem happens when the bottom rack is loaded too high and the bottom items hit the spray head.

Popped old bracket off with screwdriver, with a then easy installation of the new part.

Had to remove the rubber gasket on the new spray arm to install the device, as it was hard to push into the above slot that fits the arm..

Replaced latch

Removed the top two screws that hold the dishwasher to the cabinet , remove the two screws on the bottom panel and remove the panel. Screw the levelers all of the way up and pull out the dishwasher about 6 to 8 inch. Hook the new cabe on the spring and pull around pulley and attach it to the door bracket. I replaced both cables. Reverse to complete.

Drain hose elbow (#326) had a crack in it. Disconnected power, slid dishwasher out and laid on its back. Hose had two pinch clamps to remove. Replace old hose with new one and used standard hose clamps. Put dishwasher back in place and hooked power back up. Entire process took less than 30 minutes. PartSelect had elbow for about $6. GE does not sell just the elbow. They sell whole pump setup for about $106.

Simply removed old gasket by hand, lined up center of new gasket (white dot was printed on the center of new gasket) with the tub latch and pressed new gasket into place. We have used the dishwasher about a dozen times since and hasn't leaked a drop.

I tested Heating Element with Ohm Meter-Direct Short (if open it would have been bad and I would need to replace the element. Per the Website Troubleshooting for GE dishwasher, it said Heating Element (65%), Float Switch (32%), or Computer Board (only 3% Chance of it being board). So I ordered Float Switch. Later I noticed that the dishwasher would not change wash cycles from Heavy, Normal or Light.
So I turned the Circuit Breaker on and off. This fixed the Wash Cycle.
When the Float Switch Came in, I installed it in a few minutes watching the video on the GE Troubleshooting Page. Later when it was running I checked the operation and when I opened the door, the wife says seeing the steaming water, You fixed it, the Water is Hot now ! It was all about Hot Water, not the Heating Element at all ! And I think everything was fixed when I flipped the Circuit Breaker on and off and re-set the computer board. I think replacing the Float Switch was good maintenance, cause it was really dirty and needed to be replaced soon anyway. And it may have avoided my wife's next misdiagnosis with our dishwasher. This was 2 weeks ago, and all is well.
Sincerely,
Scott

When new gasket arrived almost two weeks after it was sent out from Green Bay, I took out old gasket, marking which side was in and which out.
Then, with hands, fit new gasket in place making sure it was centered.
No leaking; it worked.
Thanks.

The part did not fit at all but not worth it to me to return it. The part I need is about 20 inches in length and the one sent was about 10 inches. I will simply call for this dishwasher to be repaired or replaced.
