GDF510PGJ2WW General Electric Dishwasher - Instructions

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!

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.

Followed video instructions step by step.
I was fortunate i had enough slack in water, electric and discharge lines to avoid disconnecting.

Two wrinkles
1. wire clips on my door had to be pulled/pried loose from door and there were two not one

2. could not slide dishwasher out after lowering adjusters and figured out it was the mounting tabs bumpimng the granite countertop, thus the use of putty knives to slide the dishwasher out.

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.

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

The Mid Spray Arm Assembly was not spinning due to a dish that was in placed the dishwasher that was too high and hitting the arm. When it spun until it broke the center shaft. Replacement was easy. After removing power I pulled the upper tray out and removed the Conduit Mid Tiered Assembly by unsnapping it from the tray. I twisted off the broken spindle of the damaged arm assembly from the Conduit Mid Tiered Assembly and inserted the new arm and gently pushed it until it snapped into the Mid Tiered Assembly. Reinstalled the assembled parts by snapping into the tray making sure it was centered.

Replaced latch

Unhook water line . Turn off power to dishwasher. Remove dishwasher from under counter. Lay it on its back. Loosen clamps on drain pump and remove pump. Install new drain pump and tighten clamps. Be sure to put hanger in the hole on the pump. Very easy job. Reinstall water line and put dishwasher back under counter. Turn on power to dishwasher. Go to go.

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.

Simply pulled the new one out of the box and put it into the dishwasher.

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!!!

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.

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

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

Just took old one off & install new one. Snaps on dish rack. Took 5 minutes.
