GDF450PSR5SS General Electric Dishwasher - Instructions

Took it out of the box and set rollers on track
rolled in place ALL DONE

the design of this part is easy to break when closing the top rack.

there is a hub that clicks in place and a spinner within this that makes the water spray evenly on the top of the tub of the dishwasher

the part broke when closing the rack [a dish too tall hit it]

it took less than 5 minutes to replace as the part just clicks into two edge spots i did this without removing the rack or even looking into the tub all by feel

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

Popped the old one off. Popped the new one on. Easy as that.

I took out the old one and simply inserted the replacement. It was an exact replacement part and thus a perfect fit. Dishwasher is working fine now! Cost was around $40 (shipped) which I thought was reasonable.

Chances are your Lower spray arm is worn or jets are off. Replacing this part is very easy. Grab the base of the lower spray arm, twist and pull straight up. Place the new one in and twist lock in place. Repair complete!

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

A quick twist of the locking nut

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.

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.

Ordered the Upper and Lower rack assemblies. Lower rack slid right in as the wheels came with it. Upper rack had to be removed from rails and old spray arm removed so it could be used with new rack (spray arm does not come with it). Whole process took about 10 minutes, no tools needed other than your hands. Overall, installation was no hassle but sad that the racks don't last over 2 years.

After hours looking for problem. I tried cleaning door gasket. Did not stop leak. Looked at lower water spray arm and it was split. It is literally a 2 minute repair to remove and install. Knock on wood, no leaks in the last 10 washes.

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

Replaced all 3 spray arms in less than 10 minutes.The top one came in two pieces,the mounting bracket and the arm.Snap the bracket on the dishwasher first , then attach the arm to the bracket.

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