PDT720SSH7SS General Electric Dishwasher - Instructions

Followed troubleshooting procedure to determine that defective Flood Switch caused the problem and not the Heating Element. Replaced only the Flood Switch. I also replaced a deteriorated door gasket.

De-installed dishwasher from cabinet, removed door, and tipped unit over with back of tub resting on floor.

I followed the document referenced here for the troubleshooting and repair procedures: GE Appliances Technical Service Guide, 2012 GE Dishwasher, 31-9226.pdf available on web.

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.

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.

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.

I replaced the Flood Switch Part Number: WD21X10519.
I found that be removing the bottom front cover under dishwasher door, there was a small black plastic clamp holding up the wiring cable. By disconnecting the clamp, it gave me a few more inching of wire inside the machine, which made disconnecting old flood switch easier. It also help in installing the new flood switch. Then finally i reinstall the clamp cable under the machine to finish the job.

2 hose clamps, connect the wire with the wire adaptor suppled

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.

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

Just snap part in position quick to do.

Looked upm the problem it said door wasn.t closed so cause was the door latch. put in the new one no change so I bought a new dishwasher

I followed the U tube instructions already put out part select.

Followed the instructions on the video, it was pretty straight forward. It was helpful to know what to expect before hand like removing accumulated water in the drain before removing the flood switch so as not to have that water drain under the dishwasher. Knowing to have a nut driver with magnetic tip was helpful in removing and reinserting the screws. all in all it was pretty easy repair.

Had to trouble shoot to isolated the true fault condition. Checked heating element was good
Researched symptoms on YouTube
Removed and inspected float switch part
Ordered and replaced part.

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.

I removed the old roller wheels and the new roller wheels snapped together and the simple instructions made the repair quick and simple..
