GDF520PGD0WW General Electric Dishwasher - Instructions

In did the drain screen, undid two nuts on top, removed panel, undid plastic ring, undid two screws with but driver, pulled sensor up, dried up any water at bottom, installed new sensor and follow steps in reverse. It worked!!!

I replaced the User Control and Display Board and it is working very well now. The important things that should be noted are to take off the door and to open the door cover by unscrewing it. Those screws are located at the bottom of the door and two are hided inside.

The old gasket pulled right out with no tools needed,
The new gasket went in the same way.

Results:
It did help on one side, but the bottom gasket also needs to be replaced it has a couple of tears one on each end.

Next Steps:
When the bottom gasket gets here I will replace that and it should be as good as new.

Super easy repair, just removed the old latch and replaced it with the new one.

Replaced gasket with a new one before further problems occurred. Got to get it in but it was relatively easy to place and snap in just make sure it fits on the right place where gasket inside meets ridges on door so it will be on properly for proper fit.

Replaced motherboard, parts select,very helpful in helping diagnose problem! Exchanged parts, credit account after returned parts. Great customer service All good stuff! They brought their A game for this diy-er...

So after noticing some horrid food waste build up in my 9 year old dishwasher, I determined it wasn't heating the water during the wash cycle. I came on here to check how to replace the heating element and was surprised when the flood switch was instead strongly recommended as the first repair step.

I ordered the part, and prepped the dishwasher for the repair (Pro-tip: Clothes pin attached to the bottom of the flood switch wiring harness ensures it doesn't slip down below the opening during the part swap!). The part swap and reassembly only took 5-10 mins or so after prep and dishwasher is now heating water and running great again. Many thanks to partselect.com for the detailed installation guides/videos and the parts recommendations!

Open box...remove old rack from dishwasher...roll in NEW rack. Done!!!

Simply unscrewed the old damaged arm and screwed the new one on, took less than a minute

The base of the spray arm literally just spins a little bit into place like a luer lock. Takes two seconds to replace.

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.

Took off the door and separated the two door pieces. Unscrewed the old dispenser and replaced it with the new one.

Replace all three spray arms and knocking sound disappeared.
Unscrewed counter clockwise old sprayer arms and lifted. Replaced with new sprayer arms and noise disappeared.

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

YouTube search indicated the common problem was the Dishwasher Electronic Control Board, part # WD21X10537. YouTube was wrong. $83.76 mistake. (not Parts Selects fault)
I continued my search and stumbled on JustAnswers.com for $38.00.
They diagnosed the issue by me describing the lights that were blinking and for how long, and quickly told me the door latch is not registering. However, said it is rarely the door latch, but rather the Electronic Control Board, part # PS12726419 for $105.90. What the heck, I'll bite.
Bought both parts at Parts Select, quick shipping, solid packaging and good return policy (learned from previous experience). I did not return the 1st part, figured it probably wasn't long for this world anyway.
Dishwasher is running fine again. The combination of JustAnswers.com and PartSelect.com is far better than an extended warranty. Extended warranties last 3 yrs in most cases and cost as much as I spent. Someone with smaller hands could have done both repairs much quicker.
